Study analyzes danger of parasites to Bengal tigers in South Asia
- Researchers analyzing parasite infections of Bengal tigers and their prey population in the Sundarbans in Bangladesh have raised concerns about the critically endangered species’ conservation.
- Researchers in South Asia warn that parasitic infections can act as silent killers to stressed tigers and cubs.
- Human settlements near habitat elevate the risk of parasite transmission between wild and domestic animals, the research suggests.
- Experts recommend reducing human-wildlife contact and adopting integrated and long-term wildlife disease prevention.
Ebola outbreak underscores food insecurity crisis in DRC
The recent Ebola outbreak caused by the Bundibugyo strain of the virus has reportedly claimed more than 3,000 lives, and more than twice as many reported cases, in the Democratic Republic of Congo, according to the U.S. Centers for Disease Control and Prevention. At the same time, analysts warn that roughly 26 million people across […]
Drought is deepening a health crisis among Peru’s recently contacted Indigenous Matsés
- Since initiating contact with the outside world in 1969, the Matsés Indigenous people of the northeastern Peruvian Amazon have faced a barrage of epidemics.
- During a recent visit to the Matsés reserve, Mongabay found a population still suffering from outbreaks of deadly malaria and hepatitis B, exacerbated by state neglect and environmental threats like drought.
- Matsés leaders, anthropologists, and health experts warn that exposure could be fatal for isolated groups neighboring Matsés land, as well as those in nearby reserves across the wider Yavarí-Tapiche Territorial Corridor.
- Drought and an intensifying El Niño could further compound these health pressures by disrupting rainfall patterns, creating conditions that allow malaria-bearing mosquitoes to proliferate and affecting river transport for medical care.
Scientists use mining data to build malaria alert system in the Amazon
- Researchers have found a direct link between illegal mining, miners’ routes, and malaria cases in the Yanomami Indigenous Territory in Brazil.
- Now, they’re working on an alert system that will rely on mining data to warn local health agents about the risk of a malaria outbreak.
- The number of malaria cases dropped sharply after authorities expelled illegal miners from the Yanomami land, but Indigenous people worry the potential return of a right-wing government after October’s election could revive the humanitarian crisis.
Community programs linked to lower forest loss in Indonesia’s Borneo during COVID-19
- As climate and economic shocks put pressure on tropical forests, a new study suggests support for rural communities could help protect forests while strengthening their ability to withstand crises.
- Forest loss in protected areas of West Kalimantan on the Indonesian part of Borneo fell during the COVID-19 pandemic, with a larger decline in villages receiving health and livelihood support, the study finds.
- The findings point to health care, alternative livelihoods and other social support as potential tools for easing pressure on forests and helping forest-dependent communities adapt to future economic and environmental shocks — although the study does not establish a direct cause-and-effect relationship.
As hay fever sufferers grow in Japan, the country is looking to plant no-pollen trees
- More than 40% of the population in Japan suffers from hay fever, or kafunsho, an annual affliction.
- The majority of Japan’s hay fever sufferers are allergic to the pollen of two trees — sugi and hinoki. Both trees were widely planted in the years following World War II as a much-needed source of timber.
- In 2023, the Japanese government announced a solution: Fell 750,000 hectares of sugi and hinoki trees in a bid to cut the problem off at the root.
- After decades of work, researchers have developed more than 30 strains of low-pollen and no-pollen sugi trees, which will replace some of the trees cut down.
Congo’s Ebola outbreak records one of its highest weekly death tolls yet
BUNIA, Congo (AP) — More than 300 people died of Ebola in eastern Congo in the past week, one of the highest weekly tolls yet, government data showed Monday, as health workers struggle to catch up with an outbreak that is spreading at unprecedented speed. Ministry of Health data showed that as of Saturday, the outbreak had recorded […]
A deadly cross over: In South Africa, rabies moves from land animals to seals
- Cape Town, South Africa, has recorded 135 incidents of aggressive seal behavior toward humans since September 2021, including injuries that led to hospitalizations.
- Researchers suspect the cause is rabies, a disease normally associated with land animals but has leapt to Cape fur seals.
- Since May 2024, rabies cases have been confirmed in Cape fur seals along the Western Cape and Northern Cape coastlines of South Africa — the first time the virus has established itself in a marine mammal population anywhere in the world.
- Beyond attacks on humans, researchers worry whether the disease will spread to other marine mammals, as seals interact with different species.
Bat virus fragments turn up in fertilizer sold in Thai markets, study finds
Researchers have found the first genetic evidence of bat-borne viruses within commercially sold bat guano fertilizer in Thailand. However, the viral strains the team detected are not known to infect humans. Moreover, since the researchers only identified fragments of viral RNA and did not isolate live, intact viruses, they could not confirm if the genetic […]
Delays, biosecurity failures worsened flu outbreak at Nepal zoo, probe finds
- The bird flu outbreak at Nepal’s only zoo killed or led to the culling of at least 63 animals, including birds, wild cats, civets, two leopards, a jackal and a bear, an inquiry has found.
- The inquiry’s report says contaminated feed and water in open bird enclosures, along with failures in animal-food handling, likely helped the virus spread.
- The zoo remained open for five days after a rapid test indicated bird flu, despite receiving an earlier warning about infections among crows in Kathmandu.
- Less than two weeks after reopening following the bird flu outbreak, the zoo recorded another disease outbreak that killed three wild boars from African swine fever.
As DRC confronts largest Ebola outbreak, health agencies revise strategy
- The Central African country is facing its largest and also the fastest-spreading Ebola outbreak on record.
- Health agencies are seeking to revise their strategy to tackle the public health crisis but focusing on response at the village level in the affected provinces of the DRC.
- Dr. Jean Kaseya, director-general of Africa CDC underscored the need to bring the outbreak response to the village level, saying that a community-centered approach helps build trust between local populations and health teams while strengthening participatory surveillance.
- One of the reasons this outbreak has turned out to be more difficult to contain is because a rare strain of the Ebola virus, Bundibugyo ebolavirus, is driving the cases.
Brazil’s wildcats face multiple diseases due to habitat fragmentation
- Throughout Brazil, the contact between domestic cats and wild felines has been exposing threatened, biologically vulnerable feral species to diseases, which can reduce their populations.
- According to experts, habitat fragmentation is a common denominator of this crisis, from the Amazon to the Pampa, where felines are forced to leave the boundaries of their native areas and approach sites modified by human action.
- From the imposing jaguar to one of the smallest and rarest, the pampas cat, no Brazilian feline escapes the risks of contracting fungi, bacteria, parasites, and known viral diseases, such as feline leukemia and others.
- Studies and veterinarians warn that mass vaccination of domestic animals and the preservation of natural areas are key pieces to address this problem.
Some free-roaming cats in New York City are parasite ‘super-shedders,’ study shows
- New York City has a large population of free-roaming cats, which can harbor and transmit zoonotic parasites.
- Some parasites shed by cats remain in the environment for long periods and infect pets, wildlife and humans.
- Researchers recently tested cats that were captured during a trap-neuter-return program in New York City and found that more than half were infected with at least one type of parasite; young male cats shed large numbers of parasite eggs into the environment.
- The study’s authors suggest that trap-neuter-return programs incorporate disease management and surveillance to better monitor and mitigate zoonotic health risks.
Nepal zoo bird flu outbreak raises alarm for national parks
- In June, a bird flu outbreak at Kathmandu’s Central Zoo killed at least 65 animals from more than 20 species, exposing flaws in Nepal’s disease surveillance.
- The outbreak has raised concerns that similar outbreaks could go undetected in national parks, where wildlife is not routinely monitored.
- Experts warn that shared feeding sites, including Nepal’s renowned “vulture restaurants”, and the reliance of wild carnivores on domestic poultry could create pathways for influenza viruses to spread between birds and mammals.
- Despite the outbreak and recommendations from the zoo’s own investigation committee for contingency plans, stronger biosecurity and rapid reporting, Nepal’s wildlife and livestock authorities say they have no plans for park-specific surveillance or response programs.
Australia confirms first mass bird flu mortality in wildlife
Australia has confirmed the country’s first mass mortality of native seabirds from the deadly strain of avian influenza, H5N1. On Aug. 1, authorities confirmed the positive cases among 49 dead and 35 sick greater crested terns (Thalasseus bergii) at Baudin Rocks, an island roughly 5 kilometers (3 miles) off South Australia’s southeast coast near Cape […]
Ebola responders persevere in the DRC as Uganda nears end of outbreak
- Community leaders and local radio stations are fighting widespread misinformation, while resistance to safe burials has fueled attacks on Ebola treatment facilities.
- The current Ebola outbreak has become the fastest-growing outbreak recorded in the Democratic Republic of Congo, with more than 3,360 reported cases and nearly 1,487 deaths in about two and a half months.
- Aid workers say funding cuts have weakened disease surveillance, community outreach and logistics at a time when the response is already constrained by armed conflict.
- According to WHO, in Uganda, the last confirmed patient was discharged from care on July 16, and the 42-day with no new Ebola cases countdown necessary to declare the end of that country’s outbreak has started.
Researchers find ‘priority zones’ for yellow fever vaccination of golden lion tamarins
- Golden lion tamarins, an endangered species of monkey endemic to Brazil’s Atlantic Forest, are susceptible to yellow fever: An outbreak in 2017-2019 wiped out roughly 30% of the population.
- A new study finds that certain environmental factors, including habitat connectivity and human population, were linked to higher numbers of deaths during the outbreak.
- Scientists have identified areas where tamarins could be at high risk for yellow fever transmission, which could help guide vaccination efforts and help protect the monkeys in the event of another deadly outbreak.
Study suggests the threat of mold-associated illnesses may be underappreciated
NEW YORK (AP) — A first-of-its-kind U.S. study suggests invasive mold infections may be an underappreciated — and potentially deadly — threat. The researchers detected about 450 cases in Atlanta-area hospitals over five years. About a third of the patients died in the hospital. The findings, published this week by the U.S. Centers for Disease Control and […]
Study investigates how to prevent viral spread from bat guano in Southeast Asia
- Scientists say they have found the first evidence of bat-linked viruses in commercial fertilizer made from bat guano in Thailand.
- Bat guano harvested from roosting cave sites is widely used, both commercially and informally, as agricultural fertilizer across many parts of Southeast Asia.
- While the viral strains detected in the study are not known to infect humans, the research urges the fertilizer industry to introduce stronger safety precautions throughout the supply chain to minimize the risk of zoonotic disease transfer.
- Experts also note the need to adhere to a “One Health” approach that minimizes disturbance of bat roosts and habitats to maintain safe ecological boundaries between potential zoonotic disease reservoirs and people.
WHO evacuated health workers from Ebola treatment center due to armed clashes
On July 15, gunfire erupted between armed groups near an Ebola Treatment Center (ETC) in Nyankunde (or Nyakunde), located 45 kilometers (28 miles) southwest of Bunia in the eastern Democratic Republic of Congo (DRC). Following the fighting, medical personnel from the World Health Organization (WHO), Africa CDC and the NGO Samaritan’s Purse evacuated from Nyankunde, […]
Peru’s only penguin species at risk from upcoming El Niño and bird flu, experts warn
- The Humboldt penguin is the only penguin species to breed in Peru, inhabiting the country’s coastal deserts. But since 2022, the species’ has been under pressure from the spread of avian influenza, followed by El Niño.
- Between 2022 and 2025, the population of Humboldt penguins has dropped by two-thirds across 34 islands and peninsulas on the Peruvian coast.
- Experts monitoring the species say penguins are abandoning their nests as they already feel the impacts of the upcoming El Niño episode, which changes temperatures in coastal waters and diminishes the amount of prey fish available.
- Scientists are asking both the national government and the IUCN to revise the species’ status to reflect the increasing threats and boost conservation efforts.
Laos’s illegal wildlife shops keep growing despite enforcement, investigators find
- Illegal wildlife shopping sites targeting Chinese tour groups in Laos appear to have expanded despite recent law raids, with investigators identifying up to 35 suspected locations, nearly double the number Mongabay documented in 2025.
- Investigators say the shops, embedded in low-cost package tours, continue to pressure tourists into buying illegal wildlife products, while some restaurants are reportedly serving highly threatened pangolins to tour groups.
- Laotian authorities say they’ve seized illegal wildlife products and launched investigations, but conservation groups argue enforcement remains too limited to disrupt the broader network.
- Experts warn the trade could undermine Laos’s efforts to improve its standing under the global wildlife trade convention, and say a coordinated regional response is needed to prevent the business model from spreading elsewhere in Southeast Asia.
Microplastic pollution can fuel rise in antibiotic resistance, studies find
- Plastic pollution and drug-resistant infections are usually regarded as separate global crises. But emerging research suggests links between them: Microplastic particles in the environment are colonized by bacteria, and those bacteria develop antibiotic resistance at an unprecedented rate.
- Studies have found that bacteria exposed to microplastics develop enhanced resistance to antibiotics. Microplastics actively promote the formation of biofilms, communities of bacteria that stick to each other on a surface. These protect the bacteria and aid the development of drug-resistance genes. They also encourage resistance genes to spread from one bacterium to another.
- In high-income countries, drug-resistant infections are often overcome with medical care. Yet in low- and middle-income nations, where sanitation facilities and wastewater treatment plants are less available, infections resistant to antibiotics are prevalent and often fatal. Plastic waste is also rampant in many such nations.
- Research into the link between microplastics and drug resistance is ongoing, but action is needed now, say experts. Limiting opportunities for bacteria, antibiotics and microplastics to mix with each other, via better wastewater management and surveillance of drug-resistant strains, may be the best hope.
Clinical trials begin in DRC epicenter of Bundibugyo strain of Ebola
- Clinical trials that aim to establish a standard treatment for the Bundibugyo strain of Ebola, which is driving the current outbreak, began on July 2.
- The trials are being conducted in Evangelical Medical Center in Bunia, the capital of Ituri province, the epicenter of the outbreak.
- Dr. Placide Mbala of the National Institute of Biomedical Research (INRB), is in charge of clinical trials, said the trials could take between three and six months, depending on how the disease evolves on the ground.
Sri Lanka intensifies fight against dengue and the mosquitos that cause the infection
- Sri Lanka has recorded more than 56,422 dengue cases from January to July 1, adding pressure to the country’s healthcare system as the caseload continues to increase.
- DENV-2 is the dominant dengue serotype causing a higher number of infections at present, health officials say.
- According to academics, unplanned urbanization and climate change are factors contributing to the spike in dengue cases in South Asia and many other regions.
- Meanwhile, the Aedes vector is evolving and adapting, increasing the mosquito’s ability to survive in constantly changing environmental conditions, researchers say.
France confirms its first Ebola case as DRC outbreak continues to grow
A positive case of Ebola disease has been identified in France, a first for the Western European country. According to the World Health Organization (WHO), the patient is a healthcare worker from the NGO Alliance for International Medical Action (ALIMA) who contracted the disease in the Democratic Republic of Congo (DRC) before returning to France. […]
Seizures reveal macabre grey parrot blood trade in Cameroon
- A grim, illicit trade in the blood of endangered African grey parrots is emerging near Cameroon’s Lobéké National Park, a stronghold for the species, according to TRAFFIC, a wildlife trafficking monitoring NGO.
- This trade first came to light in 2025 when forest authorities apprehended individuals caught illegally trapping grey parrots in the park. During interrogation, the poachers said that blood was extracted from trapped birds and likely used for medicine and religious practices.
- These intelligent birds are in demand as pets worldwide; their skulls and colorful feathers are used in belief-based practices, as a cure for speech problems and as decor. Decades of trade has pushed African grey parrots to the brink of extinction.
- Not a lot is known about this blood trade, but conservationists say it points to a general trend where wildlife traffickers are shifting to hard-to-detect products, making it challenging to combat illegal commerce.
Nepal’s Central Zoo faces questions over its bird flu response
- At least 40 animals have died at Nepal’s Central Zoo since a bird flu outbreak began in mid-June, most of them raptors and carnivores including a common leopard, though the zoo has refused to officially confirm the toll.
- Officials gave conflicting dates for when the first dead birds were found, and the zoo stayed open until June 19 despite a positive rapid test on June 14, a five-day gap that allowed the virus to spread through the facility.
- Investigators suspect feral crows were the likely vector, with a nest found near the barn owl enclosure and droppings possibly contaminating the owl’s water supply; contaminated raw chicken fed to carnivores is also being examined.
- The inquiry into the response is being led by the same spokesperson who has publicly defended the zoo’s handling of the outbreak.
Deadly bird flu strain confirmed in Australia for first time
A deadly strain of avian influenza, H5N1, that has killed millions of wild and domestic birds and mammals across the globe, has for the first time reached Australia’s shores. Australian authorities confirmed that two migratory seabirds, a brown skua (Stercorarius antarcticus) and a northern giant petrel (Macronectes halli), have both tested positive for H5N1, a […]
We must prevent the next pandemic, not build perfect conditions for it (commentary)
- How the world reacted to the recent disease outbreaks tells us more about inequity than about epidemiology, a new op-ed argues.
- Beside the lopsided coverage of affected populations, both outbreaks point to the fact that these events are not isolated biological accidents, but predictable consequences of the ecological, economic, and political systems we have built.
- “The first signal of the next outbreak will not come from a high-tech laboratory or a global summit. It will most likely come from a ranger deep in a protected forest, a community health worker in a remote village, or a hunter reporting a dead chimpanzee along a forest trail. The question is whether the world is willing to invest in listening before the crisis reaches everyone else,” the author writes.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
As human Ebola cases climb in DRC, critically endangered gorillas are at risk
- Gorillas are vulnerable to communicable diseases that infect humans and other nonhuman primates, including the Ebola virus.
- A new Ebola outbreak was announced in the Democratic Republic of Congo in mid-May, but so far, there have been no reported cases of gorilla infection. Previous outbreaks have devastated western lowland gorillas.
- Armed conflict hampers both conservation and efforts to monitor both Grauer’s and mountain gorilla populations in DRC. They also impair the public health response, which has also been seriously impacted by cuts in U.S. funding under the Trump administration.
- Gorillas are highly social animals, which facilitates spread of infectious disease. Infants and females are disproportionately affected, which has serious consequences for recovery of devastated populations.
Four years to earn their trust: Habituating bonobos in DRC’s Salonga National Park
- In the heart of Salonga National Park, one of Africa’s largest protected areas, researchers are trying to earn the trust of wild bonobos, one of the continent’s most endangered great apes.
- Conservationists say that habituation is a critical tool for protecting the species, allowing scientists to monitor their health, behavior and populations while strengthening long-term conservation efforts.
- As the Democratic Republic of Congo confronts a renewed Ebola outbreak in its eastern region, park officials acknowledge the ever-present risk of zoonotic disease transmission. However, when conducted under strict biosecurity protocols, bonobo habituation offers significant conservation, scientific and ecotourism benefits that outweigh the risks.
Evidence linking bats to Ebola inconclusive, scientist says. ‘Solution is not fear’
- The current Ebola outbreak in the Democratic Republic of Congo has sparked efforts to develop a vaccine for this current strain, but has also brought renewed attention to the long-standing question of where the virus originates.
- As scientists race to better understand and contain the Bundibugyo strain, they continue to search for the origins and transmission pathways of this virus, which has a 50-60% mortality rate in humans and has also wiped-out substantial numbers of gorillas and chimpanzees.
- As with previous zoonotic disease outbreaks, bats are once again under scrutiny. During the COVID-19 pandemic, for example, bat colonies were destroyed in countries including India, Peru and Cuba, while bats were culled in Indonesian markets and driven from urban areas in Rwanda amid fears about disease transmission.
- While there have been no reported cases of bat culls linked to the current Ebola outbreak, Dr. Paul Webala, a wildlife biologist at Maasai Mara University in Kenya who has studied bats for more than two decades, cautions against such actions. He argues that bats play a critical ecological role and notes that the scientific evidence linking bats directly to Ebola outbreaks remains inconclusive.
Genetic study reveals extinction risk for unique mangrove-adapted pampas cat
- The San Pedro de Vice dry mangrove habitat on the northwest coast of Peru hosts a very small population of desert pampas cats (Leopardus garleppi). It’s part of a population unlike any other across the species’ Latin American range, which stretches from southern Colombia to northern Argentina.
- While the desert pampas cat is normally found in arid deserts, dry forests or grasslands, this small coastal population is one of a kind in that it is uniquely adapted to a dry mangrove habitat bordered by desert.
- While camera-trap data initially suggested a healthy population in San Pedro de Vice, a recent genetic study performed on scat determined there are just nine cats in this isolated area, all of them related, with just two actively breeding — raising concerns this unique population can’t survival without conservation intervention.
- Researchers say this population’s story is a warning to conservationists that other small cat species worldwide thought to be thriving may be facing isolation and genetic bottlenecks in fragmented ecosystems, risking multiple local extinctions. But expensive genetic studies of hard-to-find scat make assessments difficult.
Confinement and disinfected bedding: An ape sanctuary in DRC responds to Ebola
- The Lwiro Primates Rehabilitation Center, located in South Kivu in the eastern Democratic Republic of Congo, has gone into lockdown to protect its primates.
- Primatologists say Ebola transmission from infected wild primates to humans has been documented repeatedly but there are no recorded cases of transmission from humans to great apes.
- Emergency plans have also been activated to limit the spread of the virus in the protected areas of the Greater Virunga Landscape, a transboundary area shared among the DRC, Rwanda and Uganda.
- As of May 27, the World Health Organization has already recorded 223 suspected deaths linked to the current outbreak.
Can deforestation predict Ebola outbreaks? Q&A with CDC’s Carson Telford
- In 2024, a group of researchers with the U.S. Centers for Disease Control (CDC) used machine learning to analyze 24 Ebola outbreaks between 2001 and 2022 to isolate which geographic and other variables they shared in common.
- They found that forest loss and fragmentation are among the most important predictive factors for where Ebola outbreaks occur.
- Carson Telford, who led the research, told Mongabay modeling like this can strengthen communication and readiness for outbreaks like the one taking place in the eastern Democratic Republic of Congo and Uganda.
‘People kept dying’: Interview with Dr. Macky Mbavugha on DRC’s latest Ebola outbreak
- The Democratic Republic of Congo is facing a new Ebola outbreak caused by the Bundibugyo strain, for which there is currently no approved vaccine or treatment.
- More than 1,000 suspected cases and more than 238 suspected deaths have already been recorded in the DRC, while the disease has also spread into neighboring Uganda.
- Armed groups, population displacement and intense mobility around gold mining areas are accelerating transmission risks, says Dr. Macky Mbavugha of the International Rescue Committee (IRC).
- Mongabay spoke to Dr. Mbavugha about why it took so long for authorities to identify the rarer Ebola strain, and how USAID funding cuts have severely weakened disease surveillance, community outreach and emergency response capacity.
Ebola outbreak draws attention to longstanding virus spillover risks in western Uganda
- In western Uganda, especially in districts bordering the Democratic Republic of Congo, human-bat interactions are frequent and can increase viral spillover risk, experts say.
- The Bundibugyo ebolavirus, a genetically distinct Ebola strain first identified in Uganda’s Bundibugyo district in 2007-2008, is driving the current outbreak.
- Experts warn that current Ebola vaccines and treatments, largely developed for the Zaire strain of ebolavirus, may offer limited protection against the Bundibugyo strain, underscoring major preparedness gaps.
- Field research highlights how humans may be exposed to these viruses including through hunting and consumption of bats in some communities, raising concerns about potential transmission of zoonotic pathogens.
Ebola outbreak reaches major cities in DR Congo, Uganda amid fears of regional spread
The Ebola hemorrhagic fever virus outbreak that began in the Democratic Republic of the Congo was officially confirmed by the World Health Organization (WHO) on May 15. Less than a week later, the death toll is rising with at least 600 suspected cases and 139 suspected deaths linked to the disease, as well as 51 […]
Measures must be taken now to prevent pandemics at the source, says epidemiologist
“[The]cruel irony here [is] that the world cannot get its act together to address these threats … people are dying, animals are suffering, we’re losing rainforest … these are all interconnected threats,” Neil Vora tells me on this week’s episode of the Mongabay Newscast, just a day after the World Health Organization (WHO) reported more […]
More than a million live birds imported to Asia in 15 years, report finds
Hong Kong and Singapore imported more than 1 million live wild birds between 2006 and 2020, according to a new analysis of customs data published in Conservation Biology. Nearly two-thirds of the birds were from Africa. The study highlights a massive, often under-regulated trade that threatens wild populations and poses significant risks for the spread […]
At least 65 dead in latest Ebola outbreak in eastern DR Congo
A new Ebola outbreak has been declared in the eastern Democratic Republic of the Congo, according to an announcement made by The Africa Centres for Disease Control and Prevention (Africa CDC) on May 15. Sixty-five people have died and around 246 suspected cases have been identified so far, mainly in the Mongwalu and Rwampara health […]
The European wildcat hovers between recovery and local extinction
- European wildcats are making a comeback in the Czech Republic, where they’re critically endangered. Conservationists found evidence of this species breeding in the Lusatian Mountains.
- Though these wildcats, similar in size to large domestic cats, aren’t at risk range-wide, some populations face local extinction.
- Experts note that positive recovery in Central European countries is countered by declines and a lack of basic population data elsewhere.
Australia’s declining tree health is a slow-burning crisis (commentary)
- Unlike destructive bushfires, tree health is often treated as a niche or technical issue, but its implications pose equally important questions about ecological resilience and public health, a new op-ed argues.
- Threats to Australian tree species are multiplying like an invisible bushfire via a proliferation of introduced insects and pathogens, the authors suggest, ahead of his country’s first national forum on the topic later this month, Safeguarding Australia’s Tree Health, in Brisbane.
- “We recognize bushfires as a national crisis because their impacts are visible and immediate, but some ecological crises arrive more quietly. If we fail to notice them early, the damage can become harder to reverse for forests, for biodiversity, and for the communities that depend on them,” they write.
- This article is a commentary. The views expressed are those of the authors, not necessarily of Mongabay.
As wildlife trade expands, so do pathways for disease spillover to humans
- Another study has shown that the worldwide trade of wild animals increases the spread of disease between wildlife and humans. The new research focused on mammal species.
- Any sale of wild animals, their meat or products increases risk the that contagious pathogens may jump the species barrier and infect humans.
- Researchers found that mammals sold in the global wildlife trade are 50% more likely to share pathogens with humans than those that aren’t bought and sold. They also found that repeated and prolonged human contact may create more opportunities for spillover.
- Contrary to conventional wisdom, illegally traded species were no more likely to carry these zoonotic pathogens than those imported and sold legally, often as exotic pets. The study highlights the need for stronger biosurveillance, better information sharing and a “One Health” approach to wildlife trade that considers risks to both animals and humans.
Linking habitats strengthens wildlife microbiomes, helps fight disease: Study
- It has long been known that when terrestrial and aquatic habitats, vital at various times during a species’ life cycle, become disconnected due to human activities (a process known as habitat split), the impacted species can become more vulnerable to disease and see major population declines.
- A new study pinpoints one mechanism contributing to such losses. Researchers analyzed habitat split impacts on the skin microbiomes of frog species in Brazil’s Atlantic Forest and detected microbial changes that increased frog susceptibility to the chytrid pathogen, which is devastating amphibians globally.
- The scientists stress that their findings could likely apply elsewhere and to many species (such as birds, fish and mammals), which need varied habitats during their life cycles in order to maintain a diverse microbiome that enhances disease defenses.
- The researchers say their findings underline the need for conservation projects that protect and connect key habitats, such as forests and streams that are utilized at various life cycle stages, in order to better protect a multitude of species, not only at the macro scale, but also species at the micro scale.
Nearly a million birds shipped from Africa to Asia in 15 years; canaries top the list
- Hong Kong and Singapore, two Asian wildlife trade hubs, imported more than a million live wild birds, nearly two-thirds from Africa between 2006 and 2020, according to a new analysis of customs data. Canaries, including species declining in the wild, topped the list.
- More than two-thirds of the birds came from African countries where export regulations are weak, including Mali, Guinea, Tanzania and Mozambique.
- This massive live bird trade depletes wild populations and may spread dangerous diseases or invasive species, researchers say.
- Experts urge countries to restrict imports of live birds, implement stricter quarantine measures and adopt an approved list of pets that don’t pose risks to biodiversity or human health.
Avian bird flu surges in New York urban wildlife, increasing disease concerns
- The H5N1 strain of highly pathogenic avian influenza has spread across the globe, infecting hundreds of birds and mammal species. Few places offer a clearer view of the virus’s spread in urban wildlife than New York state, where the Atlantic Flyway and a layered surveillance system have made the virus easier to track.
- Scientists and local wildlife rehabilitators in New York City have reported a sharp uptick in suspected avian influenza cases this past winter. The current H5N1 strain is unusual not only for its significant impact on migratory birds, but for its ability to jump to a growing number of mammal species.
- H5N1 continues to surface in live animal and poultry markets across New York City, after more than a decade of recurring avian influenza outbreaks. Experts say the crowded, mixed-species conditions in these markets can amplify viral spread and create new opportunities for spillover to other species, potentially including humans.
- If H5N1 can move this readily across species in a city as heavily surveilled and globally connected as New York, experts warn that the risks may be even greater in other urban centers with more migratory wildlife, large live animal markets and weaker surveillance.
Canadian muskoxen hit by double punch of novel diseases and climate change
- New emerging diseases and other threats, including climate change, are upending muskox recovery in parts of the Canadian Arctic Archipelago.
- An emerging pathogen, dubbed Erysipelothrix rhusiopathiae Arctic clone, was linked to widespread muskox mortalities on Victoria and Banks islands from 2009-14. Another outbreak was identified on Ellesmere Island in 2021.
- Brucellosis, a zoonotic disease, is now appearing in muskoxen on Victoria Island and parts of the mainland, with rates increasing since 2015.
- These emerging diseases were identified, researched and tracked via an innovative community-based wildlife health surveillance program that teams up Inuit hunters and trappers, scientists and government agencies. Muskoxen are a key food source for many Inuit communities and play a vital role in Arctic ecology. Their loss could put food security and Indigenous culture at risk.
Open-air markets: hotspots for a lethal virus infecting macaws and parrots
- Environmental officers detected circovirus in birds seized from a market in Brazil’s northeast, signaling a new and dangerous means of transmission for a deadly avian disease.
- The outbreak was discovered at a government wildlife rehabilitation center where the birds were taken, putting animals housed there — and being prepared for return to the wild — at risk.
- In October 2025, the virus was detected in Spix’s macaws, which were declared extinct in the wild in 2019 but are being bred and rewilded in Brazil’s Bahia state.
- Experts warn of the need for rigorous monitoring and quarantine at rescue and rehabilitation centers, but some facilities don’t have veterinarians on staff.
Poop pills and gut microbes: Wildlife microbiome studies aid conservation
- Recent research into the human microbiome is revealing how closely connected it is to our health. Similarly, scientists are exploring how the microbiome in wildlife species can aid conservation efforts.
- Studies show that human action (including climate change and close proximity to people) is altering the microbiomes of multiple wildlife species. The implications of how these changes may be impacting wildlife survival and health remain unclear.
- Researchers are also exploring how supporting a diverse wildlife microbiome can improve animal health in captivity, aid recovery during rehabilitation, and even boost reintroduction success. Microbiome studies are underway on numerous species, ranging from Australian koalas to African meerkats and cheetahs.
- Though still an emerging field, fecal microbiota transplants (FMTs) are just one possible tool that researchers and conservationists are exploring in trials to see how the restoration of a healthy diverse microbiome can support wildlife conservation.
PNG’s New Ireland coastal waters causing fish deaths, human sickness
- Communities on the east coast of Papua New Guinea’s New Ireland province report that contact with the seawater there has made people sick since December 2025; residents have also reported spikes in the number of dead fish and other marine life along the shoreline.
- A group of local and international NGOs has responded, providing help with sampling to determine the cause and raising money for the affected villages.
- New Ireland’s coastal communities depend on the sea for food, but government officials have warned against eating fish until the cause of the problems has been identified.
- Government ministries have been aware of the situation for at least two months, and while leaders say that tissue, water and soil samples have been collected, no results have been released yet.
Captive-bred Panamanian golden frogs released to the wild
Since 2009, no one has seen a Panamanian golden frog in the wild. These bright yellow frogs disappeared completely when an amphibian fungal disease, chytridiomycosis, swept through Panama reaching El Valle de Anton, the last stronghold of golden frogs. Researchers at the Smithsonian Institution predicted these declines based on the pattern of disease spread, but […]
Outlook for migratory species worsens amid habitat loss & avian flu, report finds
- A U.N.-backed report finds that nearly half of the world’s migratory species protected under a global treaty are now decreasing — and about one in four now faces extinction.
- Habitat loss and degradation as well as hunting and fishing are driving these declines, but a deadly virus, Highly Pathogenic Avian Influenza, is also taking a heavy toll on bird populations.
- Wildlife corridors and protected ocean networks can play a pivotal role in conserving imperiled species: Animals need to move to find food, a mate and migrate.
Five Yanomami infants in Brazil die amid whooping cough outbreak
Five Indigenous Yanomami infants have reportedly died from a preventable respiratory illness called pertussis, or whooping cough. The outbreak began Jan. 7 in the Yanomami Indigenous Territory in Roraima state in northern Brazil. A representative of the Urihi Yanomami Association (UYA) told Mongabay that health authorities have been slow to respond. Three of the […]
Avian flu strikes California’s northern elephant seals; area quarantined
- Experts confirmed that seven young northern elephant seals on the beach at California’s Año Nuevo State Park carried a deadly form of avian influenza, H5N1, the first recorded infection in these seals.
- This highly contagious virus has circulated the globe since 2020. The U.N. estimates that as of December 2025, H5N1 had infected some 598 bird species and 102 mammal species. In 2022-23, the virus devastated seal colonies off South American coastlines, sparking increased surveillance of North American marine mammals.
- This northern elephant seal population has been carefully studied for about 60 years. With close monitoring, researchers quickly discovered that sick pups were infected with Highly Pathogenic Avian Influenza H5N1.
- Since this avian flu strain emerged, there have been 131 human infections globally, including 71 in the U.S. As a precaution, California officials have banned visitors from the elephant seal beaches and canceled guided tours.
In Myanmar’s limestone hills, people and bats are often too close for comfort
- A recent census of cave-dwelling bats in northeastern Myanmar found many karst caverns are increasingly inhospitable for the winged mammals due to human disturbance, posing risks to both bats and people.
- Bats are natural reservoirs for many viruses, researchers say, which means managing the ways humans interact with them is vital to managing potential disease spillover, researchers say.
- The main sources of disturbance are limestone quarrying, tourism and religious activities, hunting of bats for food, and guano harvesting.
- To manage the ecological threats and disease risk, the researchers recommend better conservation protections, improved land-use planning, and dedicated cave management plans that include public education programs on cave hygiene and zoonotic disease risk.
Some forest restoration linked to short-term rise in zoonotic diseases
Deforestation and land use change can accelerate the spread of zoonotic diseases — infectious illnesses that can spread from animals to humans — including malaria and COVID-19. While habitat restoration is crucial for addressing biodiversity loss and climate change, new research suggests counterintuitively that it can also temporarily increase the risk of certain zoonotic diseases […]
Malaria outbreak among Indigenous Pirahã linked to forest loss, satellite data find
- According to data from Global Forest Watch, the Pirahã Indigenous Territory in Brazil lost 7,000 hectares of tree cover from 2002-24.
- A large spike occurred in 2024, when the territory lost 3,200 hectares of tree cover.
- Government officials told Mongabay that the recently contacted Pirahã people are facing a malaria outbreak, and the deforestation is the result of an effort by Brazil’s Indigenous affairs agency to improve food security.
- The situation is complex, conservationists say, and although the clearings to plant crops may exacerbate the risk of malaria, the Pirahã people need food to improve their ability to fight the disease.
When nature becomes a security risk
Britain’s national security thinking has traditionally been shaped by familiar concerns: hostile states, terrorism, energy supply, and, more recently, cyber threats. A new assessment from the U.K. government adds a different category to that list. Global biodiversity loss and ecosystem collapse, it argues, now pose a direct and growing risk to national security, with implications […]
Mosquitoes in Brazil’s Atlantic Forest prefer human blood
As deforestation and habitat loss drive down wildlife populations, mosquitoes are increasingly turning to another source for their blood meal: humans. That’s the finding of a new study in Brazil’s Atlantic Forest, a global biodiversity hotspot with less than a third of its original forest remaining. Mosquitoes in the Atlantic Forest “have a clear preference […]
Marine heat waves and raw sewage combine to put human health at risk
- Climate change is fueling an increasing number of marine heat waves across the globe.
- When this intensifying heat is coupled with pollution — especially sewage, nitrogen fertilizer agricultural runoff, wildfire soot and possibly plastics — waterborne bacterial pathogens can multiply, raising human health concerns.
- These connections are exemplified in the escalating spread of Vibrio, a group of naturally occurring bacteria whose numbers are multiplying and undergoing global distribution shifts due to complex relationships between marine heat waves and pollution.
- Vibrio infections can range in severity but can result in sickness and death. One notorious Vibrio species is known as the flesh-eating bacteria; another causes cholera.
Reforestation and wild pig decline spark surge in miniature deer in Singapore
- Once thought extinct in Singapore, a little-known species of miniature deer has reemerged in unprecedented numbers on a small island reserve in the Johor Strait.
- Researchers documented the greater mouse-deer thriving on Pulau Ubin at the highest population density recorded anywhere in the species’ range.
- The team put the surge down to increased availability of prime habitat following a decade of forest restoration, as well as reduced competition for food after the collapse of the island’s wild pig population due to African swine fever.
- Experts say the dramatic “ecological cascade” underscores the need for long-term, ecosystem-wide monitoring throughout Southeast Asia, particularly at sites impacted by sudden shifts triggered by disease.
‘Silent epidemic of chemical pollution’ demands radical regulatory redo, say scientists
- An international team of 43 scientists has called for a “paradigm shift” in toxicology and chemical regulation globally after having found severe lapses in current regulatory systems for evaluating the safety of pesticides and plastics derived from petrochemical byproducts.
- The researchers note that the full commercial formulations of common petrochemical-based pesticides and plasticizers have never been subjected to long-term tests on mammals. Only the active ingredients declared by chemical companies have been assessed for human health risks, while other ingredients have not.
- The scientists found that synthesized pesticides and plasticizers contain petroleum-based waste and heavy metals such as arsenic that can make them “at least 1,000 times more toxic” than the active ingredients alone, posing chronic disease and health threats, especially to children — claims that the chemical industry denies.
- Researchers urge lowering the admissible daily intake, or toxicity threshold, for already approved chemical compounds; long-term testing on the full formulations of new pesticides and new plasticizers; and requiring all toxicological data and experimental protocols for approved commercial compounds be made public.
How do we stop the next pandemic?
How do we stop the next big viral outbreak? The answer to that question lies in preventing zoonotic spillovers. Thousands of pathogens have been silently circulating in our forests for centuries. However, climate change, deforestation and the trade of live animals increases the risk of bringing them in close proximity to humans. So how do […]
Chronic diseases prevalent across animals, but understudied: Study
From obesity in cats and dogs and osteoarthritis in pigs, to cancer in whales and high blood glucose in racoons, chronic diseases are increasingly becoming a concern across the animal world, a recent study finds. Most of these ailments can be traced back to human-driven changes, the author says. Antonia Mataragka, the study’s author from […]
Witch Hunt: Virulent fungal disease attacks South America’s cassava crop
- Witches’ Broom, a devastating fungal disease, has spread for the first time from Southeast Asia to Latin America, arriving in French Guiana in 2023 and has now infiltrated northern Brazil.
- Cassava is a vital crop for food security in South America and Africa, and a critical cash crop in Southeast Asia, where the fungal disease is spreading rapidly. More than 500 million people worldwide rely on cassava for their dietary needs.
- The pathogen has already caused massive cassava losses in Southeast Asia, with infection rates in some fields near 90%, and now it threatens food security in Latin America. Climate change is helping the fungus thrive and spread, as wetter conditions create an ideal environment for infection.
- Brazil has launched emergency measures, including funding research and farmer training, but scientists warn that without swift containment, cassava production across the tropics could face severe declines.
Bird flu hits migrating cranes hard in Germany as the virus flares up
LINUM, Germany (AP) — In a spot outside Berlin that’s usually a paradise for birdwatchers, volunteers have recovered nearly 2,000 dead cranes in recent days as bird flu has hit the migrating birds hard. Linum, a small village about an hour’s travel from the German capital, is a popular resting spot for thousands of cranes […]
Report urges full protection of world’s 196 uncontacted Indigenous peoples
- A comprehensive global report on uncontacted Indigenous peoples, published Oct. 27 by Survival International, estimates that the world still holds at least 196 uncontacted peoples living in 10 countries in South America, Asia and the Pacific region.
- About 95% of uncontacted peoples and groups live in the Amazon — especially in Brazil, home to 124 groups. Survival International says that, unless governments and private companies act, half of the groups could be wiped out within 10 years.
- Nine out of 10 of these Indigenous groups face the threat of unsolicited contact by extractive industries, including logging, mining and oil and gas drilling. It’s estimated that a quarter are threatened by agribusiness, with a third terrorized by criminal gangs. Intrusions by missionaries are a problem for one in six groups.
- After contact, Indigenous groups are often decimated by illnesses, mainly influenza, for which they have little immunity. Survival International says that, if these peoples are to survive, they must be fully protected, requiring serious noncontact commitments by governments, companies and missionaries.
Deforestation and disease spread as Nicaragua ignores illegal cattle ranching
- Illegal cattle ranching has torn through Nicaragua’s rainforests in recent years, supplying a growing international market for meat despite calls for better oversight of the industry.
- The practice has led to a spike in cases of New World screwworm (Cochliomyia hominivorax), a parasitic fly that feeds on warm-blooded animals
- A new investigation by conservation group Re:wild found that years of industry reforms still haven’t prevented cattle ranchers from deforesting protected areas and Indigenous territories.
‘Alarming’ levels of toxins found in free-range eggs near dumpsites globally
- A recent review paper identifies toxic chemicals, including dioxin, in free-range eggs on five continents — likely the result of nearby open burning and incineration of plastic and e-waste containing legacy and banned chemicals, as well as unregulated toxins.
- Researchers tested eggs produced near e-waste sites, dumpsites, and waste incinerators and found high levels of globally banned flame retardant chemicals, including brominated dioxins which are toxic and pose a serious risk to human health and the environment.
- Experts note that while some brominated flame retardants (BFRs) are regulated and banned, others haven’t been. Critics also note that the chemical industry often replaces individual banned chemicals with other unregulated but still potentially toxic chemicals in the same family, a process known as “regrettable substitutions.”
- Experts are calling for stronger regulation to prevent release of known toxins, not by banning one chemical at a time, but by addressing entire classes of chemicals. But a just completed UN Stockholm Convention meeting deferred listing and monitoring brominated and mixed brominated-chlorinated dioxins.
IUCN downgrades guiña threat status, prompting conservation warning
- The guiña, a small wildcat, has been moved to least concern on the IUCN Red List of Threatened Species. Found only in Chile and Argentina, this small cat was previously listed as vulnerable.
- But the threat downgrade isn’t a sign of conservation success, researchers say. Rather, it reflects more in-depth knowledge of the species. Three out of six recognized subpopulations remain highly in danger of localized extinction and need special attention and urgent conservation action.
- Some conservationists see the downgrade in status as concerning (especially considering the daunting range of threats and number of imperiled populations) and they fear the improved listing may take attention away from the species and result in a decline in conservation funding.
Research aims to link Hansen’s disease & illegal armadillo hunting in Brazil
- There are more cases of Hansen’s disease reported in Brazil than any other nation besides India. Even though the disease is highly prevalent, scientists are developing new studies to map out its occurrence with greater precision.
- One of the main objectives of the new studies is to prove that Hansen’s disease is zoonotic and can be transmitted to humans who illegally hunt wild armadillos and handle their meat for consumption.
- A study carried out by Brazilian researchers and published in May revealed a strong association in Brazil between direct contact with armadillos and a high risk of contracting Hansen’s disease.
- The study led to a new multinational project financed by the Leprosy Research Initiative in the Netherlands. It also emphasizes the role that conservation plays in containing the dissemination of zoonotic diseases and calls for new environmental and sanitation policies in Brazil.
In Panama, poison dart frog move brings hope amid amphibians’ fight with fungus
- Twelve pairs of poison dart frogs were recently translocated in Panama in a bid to strengthen the species’ chances of survival and provide answers over a deadly fungal disease threatening amphibians worldwide.
- The effort hopes to boost the population of these frogs, which play a vital role in forest ecosystems and whose toxins could be important for human medicinal use.
- The amphibian chytrid fungus has affected hundreds of species of amphibians over the last decades, leading to the extinction in the wild of 90 species, estimates say.
- Apart from the fungal disease, amphibians are also at risk because of habitat loss driven by urban development and agriculture, experts warn.
Protecting Indigenous Amazon lands may also protect public health, study says
- Healthy forests in protected Indigenous territories could help reduce the risk of certain illnesses for humans, a new study shows.
- Different factors influence how effective Indigenous territories are at protecting health, including whether a territory has legal protected status and the type of landscape surrounding it.
- Researchers found that Indigenous territories can effectively reduce the risk of vector-borne or zoonotic diseases if they’re located in municipalities with at least 40% forest cover.
- The study used a data set of respiratory, cardiovascular, vector-borne and zoonotic diseases recorded across the Amazon region between 2001 and 2019 to understand how pollution from forest fires, forest cover and fragmentation, and Indigenous territories impacted the risk from 21 different diseases.
Forests on Indigenous lands help protect health in the Amazon
Healthy forests are more than climate shields; in the Amazon, they also serve as public-health infrastructure. A Communications Earth & Environment study spanning two decades across the biome links the extent and legal status of Indigenous Territories to 27 respiratory, cardiovascular, and zoonotic or vector-borne diseases. The findings are complex, but one pattern is clear: […]
Yellow fever deaths reported among threatened captive monkeys in Colombia
An ongoing outbreak of yellow fever in Colombia is sickening and killing rare and threatened monkey species in captivity, a new study shows. Between February and May 2025, authorities reported eight deaths among four monkey species in southern Colombia’s Putumayo department, researchers note. Six of the individuals were in captivity: one white-fronted capuchin (Cebus albifrons), […]
Censured Sumatra coal plant blamed for sickening children in Indonesia’s Bengkulu
- A 2×100 megawatt coal power plant established by Chinese state-owned enterprise, Power Construction Corporation of China (PowerChina), incurred environmental penalties in 2023 from Indonesia’s environment ministry for dumping fly ash into a protected marine area off the city of Bengkulu in Sumatra.
- Residents of Teluk Sepang in 2019 formed a grassroots organization to advocate for clean air while holding to account PowerChina’s Indonesian affiliate, PT Tenaga Listrik Bengkulu.
- Data from a local clinic in Teluk Sepang showed a large share of young people living in the shadow of the coal plant suffer from respiratory diseases.
There’s hope for sunflower sea stars, with their killer unmasked and reintroductions pending
- Since 2013, sea star wasting disease, worsened by warming oceans, has wiped out 99% of sunflower sea stars from Washington state to Mexico, collapsing kelp forest ecosystems.
- Researchers from the University of British Columbia and the Hakai Institute in Canada have pinpointed the bacterium Vibrio pectenicida as a key cause of the epidemic, confirming its lethal effects through lab experiments that replicated symptoms seen in the wild.
- A coalition of aquariums, nonprofits, Indigenous groups and government agencies has successfully bred sunflower sea stars in captivity for the first time, experimenting with fresh, frozen and cryopreserved sperm, and raising 72 juveniles in a Monterey facility with plans for controlled releases.
- Guided by the Pycnopodia Recovery Working Group and a 2024-2027 conservation plan, efforts have now turned to breeding, disease research, habitat protection, regulatory engagement and public outreach, with broad community support — including from fishers — for restoring this keystone predator.
Scientists identify the bacterium behind billions of sea star deaths
More than a decade ago, a mysterious illness killed billions of sea stars, particularly along the North American Pacific coast. The sea star wasting disease caused the stars to develop lesions, their arms to fall off and their bodies to disintegrate. Now, researchers in a recent study say they have zeroed in on the cause: […]
The world’s children suffer brunt of wildfire smoke health impacts
- Around 270,000 children under the age of 5 die every year from breathing wildfire smoke, with 99% of these deaths occurring in low- and middle-income countries (LMICs), according to scientists.
- Despite a lack of extensive research on how wildfire smoke affects children’s health, recent studies have found a range of physical and mental impacts, starting in utero and continuing through adolescence. This research offers valuable evidence of a worsening global public health crisis driven by climate change-intensified wildfires.
- Researchers emphasize that children are especially susceptible to harm from wildfire smoke due to their physiology and tendency to spend more time outdoors. Also, not all smoke is the same. Combustion of different materials, ranging from plants to plastics, creates a complex mix of pollutants whose health impacts vary.
- Health experts stress that while smoke crosses borders, protections often don’t. More global research, better monitoring and action are urgently needed to protect children and other vulnerable populations from wildfire smoke.
Restoration, protection aim to save Belize’s coral reef from extreme heat and disease
- Charles Darwin described the Belize Barrier Reef, a complex system of coral reefs, atolls and cayes spanning 300 kilometers (186 miles) and cradling the nation’s coast, as “the most remarkable reef in the West Indies.”
- Today, unprecedented coral bleaching, a relatively new illness called stony coral tissue loss disease and other threats to corals are negatively impacting reef health across Belize, according to local organizations and a recent reef health assessment.
- The government is looking to identify 20% of the reef for full protection, part of an effort to roughly triple coral reef protection from 7% to 20%.
- Meanwhile nonprofit and scientific groups are doubling down on restoration and monitoring efforts.
Scientists trial chlorine as gentler alternative to antibiotics to fight coral disease
- Stony coral tissue loss disease (also known as SCTLD) spreads rapidly, causing high mortality rates among reef-building corals in the Caribbean.
- The most effective treatment known to date is the application of an antibiotic paste, but this poses a major health concern due to the development of antimicrobial resistance, which in turn exposes sea life to threats over the long term.
- Scientists have found that applying chlorine to affected reefs, delivered in a cocoa butter paste, can be both effective and more environmentally friendly, though it’s less effective than antibiotic treatment.
- Tackling water pollution and maintaining the balance of ecosystems, which are now severely disrupted in many parts of the world, would be the best strategy for safeguarding corals against disease, experts say.
Nepal launches plan to boost science, awareness to save dholes
- Nepal has launched its first-ever species-specific action plan for dholes (Cuon alpinus), allocating 262.9 million rupees ($1.9 million) over five years to address key threats such as habitat loss, prey depletion, disease and competition with larger predators.
- The plan prioritizes both scientific research and public awareness, with the highest budget shares going to understanding dhole distribution (25%) and conservation education (26.4%), highlighting a dual strategy of data-driven conservation and local engagement.
- A key innovation is the financial model, which leverages 36% of the funding from existing conservation plans for tigers and snow leopards — species that often share habitats with dholes but may also displace them.
As large scavengers decline, disease risk soars, study finds
Scavengers aren’t the most charismatic of animals, but they perform a vital task: by eating carrion, they remove dead animals from our environments. Yet large-bodied scavengers are declining worldwide, increasing the risk of the spread of diseases, according to a recent study. Researchers found that 1,376 animal species have been recorded in the scientific literature […]
Indonesian women sustain seaweed traditions in a changing climate
- The women of Indonesia’s Nusa Penida and Nusa Lembongan islands have harvested seaweed for generations.
- Climate change and tourism development now threaten seaweed cultivators’ centuries-old practices.
- In the face of these changes, seaweed cultivators are working with tourism operators and coral-conservation groups to preserve, and adapt, their traditional practices.
Researchers race to understand disease killing Caribbean corals at unprecedented rates
- Stony coral tissue loss disease (SCTLD) is a novel coral disease that first emerged in Florida in 2014, and has now spread to 33 countries and territories in the Caribbean, including along the Mesoamerican Reef.
- SCTLD affects an unprecedented number of species (more than 30 species of reef-building corals), spreads quickly, and has a very high mortality rate.
- Researchers are still trying to figure out exactly what causes the disease.
- Researchers are also trying to understand how the coral microbiome is involved in or responds to SCTLD infection, and developing probiotics that they hope will offer an alternative treatment to antibiotics, with fieldwork in Belize, Colombia and elsewhere.
Signs of hope as elephant seals rebound from avian flu in remote Chilean fjord
- An outbreak of avian flu in 2023 hammered a colony of southern elephant seals in Chile’s Tierra del Fuego region, leading to a 50% decline in its population.
- But over the 2024-2025 breeding season, the colony’s population recovered, with 33 pups being born.
- An alliance between the Chilean branch of the Wildlife Conservation Society and the regional environmental department has been monitoring this particular colony for years, braving the remoteness and extreme weather at the southern tip of the Americas.
- Experts posit that the site, Jackson Bay, may serve as a natural refuge from the avian flu because it’s geographically isolated as a fjord.
Without vultures, carcasses are slow to rot and disease-carrying flies abound
- Researchers in Costa Rica found that pig carcasses decomposed twice as fast when vultures had access to them compared to carcasses where vultures were excluded.
- The absence of vultures led to a doubling of fly populations at carcass sites, which could affect human health, since these flies can carry diseases like botulism and anthrax, and antibiotic-resistant bacteria.
- Unlike temperate regions with diverse scavenger communities, the neotropical forest system showed vultures as the primary vertebrate decomposers, with few other animals eating carcasses.
- The study highlights a major research gap since neotropical vultures are represented in only 7% of existing vulture literature, despite facing similar conservation threats as Old World vultures, like habitat loss, poisoning and power line collisions.
Invasive whiteflies pose a new threat to Bangladesh’s cash crops
- The invasion of sap-sucking whiteflies in Bangladesh’s agricultural farms, especially in those of coconuts, bananas and guavas, has become a serious concern among farmers as it can cause widespread damage.
- Farmers first noticed these insects in 2019 on coconut plants, and observed they affected the growth of the plants and yields. Research shows whiteflies have already made 61 types of plants as their hosts in Bangladesh.
- Though the researchers have yet to confirm how they entered the country, they suggest it could be via imported high-yielding coconut plants in 2014 and 2015.
- Researchers suggest deploying a parasitoid wasp, Encarsia guadeloupae, which is considered to tackle the invasion of the whitefly.
Why WHO’s pandemic prevention draft agreement takes a nature-centric, One Health approach (commentary)
- When the World Health Assembly meets next week in Geneva, it will debate a draft agreement on pandemic prevention that hinges on multilateralism and collaboration across borders and disciplines.
- The World Health Organization’s Intergovernmental Negotiating Body recently reached consensus on the draft with member states, endorsing the reality that human contact with live wildlife must be regulated or curbed, as part of prevention of pathogen spillovers.
- “Moving forward, we must invest in the systems that will prevent future pandemics and not just respond to them. This means funding integrated surveillance networks, fostering global inter-agency collaboration, and protecting the world’s remaining wild places,” the authors of a new op-ed write.
- This article is a commentary. The views expressed are those of the authors, not necessarily Mongabay.
Report alleges criminality in Cambodian, Vietnamese monkey trade
- A new report is the latest to bolster long-standing allegations that many long-tailed macaques imported into the U.S. for biomedical research were illegally caught from the wild and falsely labeled as captive-bred, with suspiciously high birth rates at breeding facilities in Southeast Asia.
- Cambodia became a major supplier of monkeys for research after China stopped exports in 2020, but investigations found indications of large-scale monkey-laundering operations, leading to legal cases, failed prosecutions, and a 64% drop in exports by 2023. Despite concerns, global wildlife trade regulator CITES did not ban the trade.
- Vietnam’s reported monkey exports also show discrepancies, with new “satellite breeding facilities” appearing without proper documentation, raising concerns that wild monkeys are also being trafficked into breeding farms.
- A tuberculosis outbreak linked to Vietnamese monkey exports highlights the public health risks, while U.S. company Charles River Laboratories faces scrutiny over its alleged role in the illegal monkey trade, seeming to benefit from political ties to evade accountability.
Meet Brazil’s often-seen but little-known hoary fox
The hoary fox can often be spotted sprinting through Brazil’s Cerrado, the world’s most biodiverse savanna. Despite this, not much is known about the small canid, says researcher Frederico Lemos in a recent video produced by contributors Augusto Gomes, Julia Lemos Lima and the Mongabay video team. Lemos and fellow researcher Fernanda Cavalcanti have made […]
With climate change, cryosphere melt scales up as a threat to planetary health
- Earth’s cryosphere — comprised of ice sheets, glaciers, permafrost and snowfall — is in a rapid state of flux due to escalating climate change, with numerous studies underlining the grave risks posed by the thaw.
- Today, that worldwide meltdown poses new threats to human lives — endangering freshwater supplies and food security while increasing the risks of natural disasters and disease outbreaks. Cryosphere loss poses immense dangers to the environment, agriculture, economy and society according to a new report.
- If emissions continue unabated, these problems will only worsen. Scientists warn of compounding risks as cryosphere melt escalates, including sea level rise, the slowing of ocean currents, and the triggering of feedbacks that will add to climate change.
- 2025 is designated the International Year of Glaciers’ Preservation. Experts are calling for drastic cuts to carbon emissions because each fraction of a degree of warming avoided counts toward the preservation of the cryosphere along with the ecosystem services that ice, snow and permafrost provide.
Dry season predictability and temperature drive dengue cases: Study
What’s new: Rising temperatures and variation in the length of dry seasons appear to influence the prevalence of dengue fever, according to a recent study conducted in the Philippines. What the study says: Cases of dengue fever are rising globally; in the Americas, they more than doubled from 4.6 million cases in 2023 to 10.6 […]
Getting rewilding right with the reintroduction of small wildcats
- Four lynx were illegally released in Scotland earlier this year by an unknown party, sparking condemnation. One of the cats died shortly after capture. That release comes amid long-running discussions of a possible reintroduction of this wildcat to the United Kingdom.
- Conservationists are working to reintroduce small cats across the globe. There are about 40 recognized species of wildcats, including a handful of charismatic big cats and at least 33 small wildcat species — with some of the most threatened felid species numbering among them.
- Mongabay spoke to experts working on small cat recovery projects in various stages of progress to understand what can make small cat reintroductions successful.
- Small wildcat reintroductions are presently underway or under consideration on the Iberian Peninsula, in Scotland, Argentina, Taiwan, Brazil, South Africa, Thailand and elsewhere.
Declining biodiversity and emerging diseases are entwined, more study needed
- A new review study traces the complex links between biodiversity loss and emerging infectious diseases — though one doesn’t necessarily lead to the other.
- Instead, complex interactions between factors (including climate change, habitat loss, agricultural practices, and closer contact between wildlife, livestock and people) can contribute to emergent infectious diseases and new pandemics.
- It’s now well understood that human actions are causing a major increase in pandemics. To stave off future global outbreaks, researchers say we need to better understand the shared upstream drivers of both biodiversity loss and emerging disease.
- The study highlights significant gaps in the monitoring and surveillance of wildlife pathogens worldwide. It suggests that prevention and early interventions targeting locales and situations where emergent disease spillover is likely are important to avoiding future human pandemics.
Mass salmon deaths hit Scottish farms as government investigates
- Hundreds of thousands of Atlantic salmon (Salmo salar) died on fish farms in Scottish waters in the final months of 2024.
- Poisonous jellyfish, disease and parasites were behind the mass mortality events, despite major investments by the salmon industry to combat these threats.
- In January, a parliamentary committee concluded an inquiry into the industry, saying it was “disappointed” by the lack of progress on environmental pollution and animal welfare issues.
Bobcats benefit both human and ecological health, but their growing populations are often misunderstood
The bobcat population has rebounded over the past 125 years, making it North America’s most common wildcat: as of 2011, there were an estimated 3.5 million bobcats in the United States alone, a significant increase from the late 1990s. These intelligent felids, Lynx rufus, have benefited from conservation efforts that have increased their natural habitat. […]
Disease surges in Indonesia community on frontline of world energy transition
- Residential areas next to a major nickel processing site on Indonesia’s Halmahera Island recorded exponential increases in diagnoses of respiratory infections between 2020 and 2023.
- During that same period, the value of nickel exports from Indonesia, the world’s largest producer of the metal, increased from around $800 million to $6.8 billion.
- Interviews by Mongabay with residents of one village in the area indicate health conditions there have deteriorated rapidly.
U.S. reports first human death from H5N1 bird flu
A person in the state of Louisiana has died from avian influenza or bird flu, also known as H5N1, the Louisiana Department of Health (LDH) reported on Jan. 6, marking the first recorded human fatality from H5N1 in the U.S. “The patient contracted H5N1 after exposure to a combination of a non-commercial backyard flock and […]
A deadly parasite turns jaguar conservation into a human health priority
- Analysis of jaguar droppings in Brazil’s Pantanal wetlands have uncovered the presence of Spirometra tapeworms, a parasite with significant ecological and public health implications that can be dangerous to people in its larval form.
- Pantanal ranchers typically see jaguars as pests because they prey on livestock; however, conservationists aim to reframe these big cats as allies in ecological balance, as they control parasite-carrying prey and serve as vital bioindicators of the biome’s health.
- The underreporting of parasitical infections in humans caused by Spirometra reveals a gap in public health awareness in Brazil, making the discovery of the parasite in jaguars a key breakthrough toward protecting communities.
- Educational workshops and practical measures, such as electric fencing, have significantly reduced jaguar-livestock conflicts while improving community practices and promoting coexistence between humans and the big cats.
Severe drought in Peruvian Amazon isolated more than 130 Indigenous communities
- A severe drought that spread over recent months in Peru’s Loreto and Ucayali regions led to the isolation of more than 130 communities.
- Record low river levels affected the navigation of boats that deliver food and supplies as well as the health and livelihoods of communities that rely on fish for food and trade.
- Indigenous leaders from isolated communities have criticized the state for failing to deliver emergency assistance, such as drinking water and medical supplies.
- The frequency and intensity of extreme drought in the Amazon will continue to increase substantially due to climate change, experts warn.
How nature protection and inspiring art are key to planetary health & preventing pandemics
Dr. Neil Vora is no stranger to dangerous diseases, as a former epidemic intelligence service officer with the U.S. Centers for Disease Control and Prevention (CDC). Vora has deployed to nations like Liberia and the Democratic Republic of Congo to combat outbreaks of the deadly Ebola virus, and is an ardent supporter of investing in […]
Elephant seal colonies in Argentina face long recovery after ‘catastrophic’ avian flu
- Avian flu, also known as H5N1, spread through marine mammal colonies in Argentinian Patagonia in August 2023, nearly doubling the death rate among southern elephant seals in some areas.
- In a recent land survey, researchers found no new cases of the disease among the seals, signaling an end to the outbreak, at least for now.
- But they also found that the total number of elephant seals had decreased by as much as 66% in some areas, the direct result of the high mortality rates during last year’s outbreak.
- Colonies will only recover with undisturbed seasons of breeding and molting, as well as access to abundant food, experts said.
Studies link stronger dengue outbreak in Bangladesh to climate change
- A typical consequence of climate change, drier monsoons with sudden bursts of heavy rain has led to days of inundation and long periods of standing water, creating an ideal situation for breeding mosquitoes, which may be linked to the stronger outbreak of dengue.
- Bangladesh has experienced noticeable changes in the timing and characteristics of its monsoon season. Traditionally occurring from June to August, the monsoon now extends from July to early October.
- Dengue cases have risen dramatically worldwide, with Asia responsible for 70% of reported instances, according to WHO. Researchers indicate that temperatures between 27 and 32 degrees Celsius are optimal for the breeding of Aedes mosquitoes, the vectors of the viral disease.
- As of Nov. 18, the death toll from the dengue outbreak in Bangladesh is 415, with around 80,000 infected, while the country recorded 1,705 dengue-related deaths in 2023.
Bobcats are back, and they’re helping protect people from zoonotic disease
- In the last 125 years, bobcats have recovered significantly from extremely low numbers, with several million individuals found throughout North America today.
- Living at the interface of urban and rural environments, bobcats face many human-caused dangers, including loss of habitat to roam, automobiles, and rodent poisons.
- Bobcats help reduce the spread of diseases from animals to humans partly because they and other large mammals are poor disease vectors. Bobcats also prey on the small rodents that easily transmit pathogens.
- It’s legal to hunt bobcats in most of the United States. California, which has for five years closed the bobcat season, may reinstate hunting in 2025. Some researchers suggest that regulators should more carefully consider the role thriving wildcat populations play in protecting human communities from zoonotic diseases before expanding hunting.
Impacts and legacies of migration across the Pan Amazon
- Although represented by only a few thousand people across 150 years, the Jesuits left a major social and cultural impact on native communities across the Pan Amazon. Their aim was to create autonomous communities based on early Renaissance concepts of equality and a spiritual vision based on the Christian Gospels. But in practice, they worked closely for the political and military interests of the colonies.
- Jesuits settled in remote places and border areas after being invited by colonial authorities interested in taking advantage of the native population’s labor force. But their arrival triggered the collapse of the Indigenous populations of the Western Amazon. Only in the late 17th century, more than 140,000 people died because of diseases brought by the outsiders.
- The success of the Jesuits and the religious colonialism that characterized the Catholic Church in the 17th century motivated other religious orders to follow similar missionary programs.
Canine distemper likely infecting & killing Nepal’s leopards, study shows
- A recent study confirms that canine distemper virus (CDV) is circulating among common leopards (Panthera pardus) in Nepal, causing fatalities; this is the first documentation of live CDV in leopards, establishing a direct link to their deaths.
- Researchers analyzed tissue samples from leopards that exhibited symptoms such as difficulty breathing and seizures, collected from areas like Kathmandu and Dolakha; they identified the virus’ genetic material and confirmed it was the Asia-5 lineage of CDV.
- The presence of different sublineages (A, B and C) of CDV in leopards suggests they may have acquired the virus from multiple sources, including domestic dogs and wild carnivores, highlighting the potential for cross-species transmission.
- The researchers emphasize the importance of controlling CDV spread through dog vaccination, as vaccinating wild animals isn’t possible.
25-fold surge in malaria at Indonesia gold frontier raises deforestation questions
- Diagnoses of malaria in Pohuwato district on the Indonesian island of Sulawesi soared by more than an order of magnitude in 2023, a health department official told Mongabay Indonesia.
- The rise in the disease has been linked to deforestation in the district as well as its large trade in alluvial gold.
- Global incidences of malaria have declined markedly since the 1990s after the Gates Foundation and other donors poured money into prevention programs, but progress in eradicating the disease has slowed in recent years.
As bird flu outbreak kills myriad wildlife species, virologists eye threat to humans
The current outbreak of H5N1, as reported by Sharon Guynup for Mongabay, is the “fastest spreading” and “largest ever” outbreak of the disease better known as “bird flu.” It’s what experts refer to as a panzootic — a widespread outbreak of a zoonotic disease affecting a broad swath of species. It has already spread across […]
Climate change threatens public health, raising the spread of food-borne diseases
- A new study finds that climate change is affecting the distribution and spread of food-borne diseases.
- An increase in the number and severity of heatwaves, droughts, and heavy precipitation events are all expected to lead to a rise in food-borne diseases, hitting Africa and Asia particularly hard.
- Investing in research and innovation can provide valuable insights into the underlying mechanisms of climate change-pathogen interactions and novel solutions for mitigating effects.
- For example, the Cameroon National Climate Observatory, ONACC, already provides national sectors, such as agriculture, livestock, and health with forecast climate information translated into local languages to facilitate monitoring in the context of global warming.
‘Polycrisis’ threatens planetary health; UN calls for innovative solutions
- Rapidly converging environmental, technological and social changes at the global level indicate the world has entered a “polycrisis,” according to a new U.N. Environmental Programme (UNEP) report. The polycrisis has major implications for Earth’s climate, biodiversity, pollution and health, according to the authors.
- Eight major shifts — including competition for natural resources, the rapid advance of new technologies such as AI, mass forced displacement and growing inequalities — are overlapping and synchronizing, intensifying the polycrisis.
- The U.N. report also identifies 18 “signals of change” on the near horizon that need to be monitored closely, many of which could cause major disruptions that would impact planetary health.
- These looming issues include new infectious diseases linked to climate change, deployment of climate-altering geoengineering technologies and an increase in “uninhabitable places.” The report underlines the need for monitoring, rapid response and inclusive decision-making to deploy a range of innovative solutions.
Animal apocalypse: Deadly bird flu infects hundreds of species pole-to-pole
- The world is currently seeing the fastest-spreading, largest-ever outbreak of H5N1, a highly contagious, deadly strain of avian influenza. Scientists say this virus now presents an existential threat to the world’s biodiversity, with the risk to humans rising as it continues to leap the species barrier, reaching new host species.
- H5N1 has already impacted at least 485 bird species and 48 mammal species, killing seals, sea otters, dolphins, foxes, California condors, albatrosses, bald eagles, cougars, polar bears and a zoo tiger. Since it broke out in Europe in 2020, this virus has spread globally. Carried by birds along migratory pathways, it has invaded six continents, including Antarctica.
- This current H5N1 animal pandemic (or panzootic) was caused by humans: A mild form of avian flu carried by wild birds turned deadly when it infected domestic poultry. Many industrial-scale poultry farms adjoin wetlands where migrating birds congregate, facilitating rapid spread.
- The toll on some bird and mammal populations has been devastating. With continued outbreaks, some imperiled species could be pushed to the brink, with wildlife already fighting to survive against a changing climate, disappearing habitat and other stressors.
As climate change shakes up global map of venomous snakes, health risks abound
- Researchers assessed the impacts of climate change on 209 species of venomous snakes from now until 2070, and concluded that while some may disappear from their range, others are likely to expand to new areas.
- Venomous snakes are among the most dangerous animals on the planet, responsible for at least 80,000 deaths a year, mostly in low-income countries with limited access to antivenom.
- Another impact on public health is the reduction in drug development: snake venom has great pharmacological potential, contributing to the production of medicines used to treat illnesses ranging from cancer to heart failure.
- Ecosystems will also face an imbalance as new species move in and existing ones go extinct, since snakes play a critical role in controlling the population of other animals such as rodents, which are also disease vectors.
In the wake of Bangladesh’s deadliest dengue outbreak, researchers respond
- In 2023, Bangladesh experienced the deadliest outbreak of dengue fever in the country’s history.
- Climate change will likely make severe disease outbreaks more common.
- Common prevention strategies, like insecticides, are becoming less effective as mosquitoes gain resistance and the nature of disease changes.
- In response, researchers, nonprofits and Bangladeshi residents are searching for ways to protect their communities and families.
How an international effort is keeping North America free of a deadly amphibian disease
Batrachochytrium salamandrivorans, better known as Bsal, is a fungal pathogen that causes chytridiomycosis, a deadly disease that’s contributing to an amphibian decline across most of the world. But it hasn’t reached North America. A new paper published by scientists from the North American Bsal Task Force confirms that after a decade of testing and monitoring, there’s […]
Animal welfare advocacy must include wildlife & invertebrates (commentary)
- Broadening the scope of animal advocacy to include wild and intelligent animals, as well as invertebrates, is more than an ethical imperative, it is a practical necessity.
- “The interconnectedness of all life forms means that these animals’ well-being directly impacts the health of all beings, including humans, as well as ecosystems,” a new op-ed argues.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Study finds best plants for bee health and conservation in North America
- A new study analyzed pollen from 57 North American plant species, identifying those most nutritionally beneficial for bees, which could inform conservation efforts and wildflower restoration projects.
- Based on their findings, the researchers recommend emphasizing roses (Rosa sp.), clovers (Trifolium sp.), red raspberry (Rubus idaeus), tall buttercup (Ranunculus acris), and Tara vine (Actinidia arguta) in wildflower restoration projects, citing their ideal protein-to-lipid ratios in pollen for wild bee nutrition.
- The research found that bees require a diverse diet from multiple plant sources to obtain a balanced intake of fatty acids and essential amino acids, as no single plant species provides the optimal nutrition.
- With many bee species facing significant threats, the researchers say they hope these findings can inform conservation efforts from policy changes to individual actions like planting native flowers and reducing pesticide use.
Kenyan farmers turn to WhatsApp & AI tools to combat crop diseases
- Farmers in Kenya and other countries are using online chat groups and artificial intelligence (AI) tools to help combat crop losses due to pests and diseases.
- New research shows chat groups modeled on those used in human health care can offer benefits to farmers and enhance their communication with plant doctors.
- Organizations such as PlantVillage and CABI are using such digital tools and chat groups to expand their reach and augment the services offered through their extension agents and plant clinics; participating farmers say the knowledge they gain through digital tools can ultimately help increase their crop yields.
African health experts warn of climate change & rising vector-borne diseases
- Climate change has become a pressing public health crisis around the world, as disease patterns worsen and emerge in regions where they did not exist before.
- Health experts are particularly concerned about the role of climate change in the rise of vector-borne diseases in Africa’s low- and middle-income countries.
- Rising temperatures can expand and extend the life cycle of disease-carrying vectors such as mosquitoes, ticks and parasites.
- Health experts discussed these issues in a recent webinar organized by the Health Rights Advocacy Forum, the African Medical and Research Foundation and the African Institute for Development Policy.
Drone cameras help scientists distinguish between drought stress & fungus in oaks
- Scientists have used remote sensing, spectroscopy and machine learning to detect sick oak trees and distinguish between drought stress and oak wilt, a fungal disease.
- A recently published study describes how researchers established a link between physiological traits of trees and light reflectance to monitor the progression of symptoms in trees afflicted by oak wilt and drought.
- They used the data to build a predictive model that can identify symptoms and detect sick oaks 12 days before visual symptoms appear.
- Oaks are vital for climate regulation and carbon sequestration; however, the trees face threats to their survival because of a fatal fungal disease as well as the worsening impacts of climate change.
Research links deforestation in Cambodia to stunting in kids, anemia in women
- An analysis of public health data in Cambodia has found increased rates of malnutrition among children born in areas where deforestation had recently occurred.
- It also found that pregnant women in these areas were more likely to suffer from anemia, a condition that often correlates with incidences of malaria.
- Cambodia has lost nearly 30% of its forest cover this century, while more than 30% of its children under 5 have stunted growth due to malnutrition.
- The study illustrates how deforestation and the ecological disruptions it causes can compound previously existing rural health issues.
The potential for tracking wildlife health & disease via bioacoustics is great (commentary)
- Bioacoustics is the passive, non-invasive recording of sounds emitted by a wide range of animals.
- Analysis of this information reveals the presence and behavior of wildlife, and can also be valuable indicator of animal health, which can then be used in ecosystem monitoring.
- “As disease prevalence skyrockets in wildlife, we are desperately in need of tools to remotely monitor ecosystem health,” a new op-ed argues.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Beneath the surface, a toxic tide threatens Bangladesh’s water lifeline
- Despite widespread water access, millions in Bangladesh lack safe drinking water due to contamination by arsenic, salinity and heavy metals as unveiled by the nation’s first comprehensive report on groundwater quality assessment.
- Depletion of groundwater, driven by irrigation and exacerbated by climate change, intensifies contamination, particularly affecting coastal areas with saltwater intrusion and surpassing safe limits in certain regions.
- Freshwater pockets and deep aquifers provide temporary relief, but experts emphasize that long-term strategies are imperative to address the problem in coastal districts.
- The Bangladeshi government’s commitment to water issues is evident, but urgent global cooperation, improved infrastructure and data-driven solutions are essential for ensuring safe water access nationwide.
Peru’s illegal pet monkey trade is also an infection superhighway
- A recent study has found that monkeys trafficked in Peru are spreading viruses, parasites and bacteria to humans all along the trafficking route.
- These pathogens can lead to tuberculosis, Chagas disease, malaria, gastrointestinal ailments, and other diseases in humans.
- Those directly involved in illegal wildlife trafficking are the most at risk of infection; however, climate change is increasing the chances of broader community transmission.
- After a brief lull during the COVID-19 pandemic, the illegal monkey trade is in full swing again in Peru, with most of the animals sold ending up as pets in local households.
Impunity for Cambodia’s exotic pet owners as trade outpaces legislation
- High-profile interventions by Cambodia’s former leader and weak legislation have allowed the illegal wildlife trade to persist largely in the open.
- The case of a gas station menagerie in western Cambodia is emblematic of the ease with which even endangered species can be bought and sold.
- The collection, owned by a police officer, includes cockatoos from Indonesia, marmosets and parakeets from South America, and a native gibbon.
- Authorities said they were aware of the collection, but were “following the format” set in the wake of their 2023 seizure of peacocks from a breeder, which culminated in them having to return the birds after then-prime minister Hun Sen criticized their actions.
Stalemate: WTO talks again fail to end overfishing subsidies
- At the World Trade Organization’s 13th ministerial conference (MC13), which closed in Abu Dhabi on March 2, negotiators failed to finalize phase two of an international treaty banning harmful fisheries subsidies.
- Despite 22 years of negotiations, member states remained divided on crucial aspects of the treaty to phase out subsidies worth an estimated $22 billion annually that support overfishing.
- The draft negotiating text includes contentious loopholes, raising concerns about fairness and effectiveness from state delegates, fisheries experts and scientists.
- Ratifications of phase one of the treaty leapt to 71 as 10 more states signed up during MC13, but 39 more are needed for implementation.
Scientists and doctors raise global alarm over hormone-disrupting chemicals
- Endocrine-disrupting chemicals, which harm the human body’s regulation of hormones, have become ubiquitous in consumer products, food, water, and soil, says a new report, leading to serious global health impacts.
- There are some 350,000 synthetic chemicals and polymers used worldwide, and thousands may be endocrine disruptors. Most were not studied for their human health effects before being marketed. Known and suspected endocrine disruptors are found in pesticides, plastic additives, cosmetics, and waterproofing finishes.
- The new report examines four sources of endocrine-disrupting chemicals: plastics, pesticides, consumer products, and PFAS. Rising rates of cancer, infertility, and obesity are suspected to be at least partially attributable to the presence of endocrine disruptors in the human body.
- The Endocrine Society and International Pollutants Elimination Network (IPEN), which co-authored the new report, are calling for legally binding global treaties to restrict and ban endocrine disruptor production and use.
Dholes latest wild canids likely making comeback in Nepal, study shows
- Dholes and Himalayan wolves were extensively persecuted across rural Nepal for preying on livestock, leading to their decline in the region.
- But recent observations suggest a resurgence of both species, possibly due to the reclaiming of their former territories: Himalayan wolves may have followed yak herders from Tibet, while dholes are believed to be recolonizing areas they had been locally extirpated from.
- Camera trap surveys and literature reviews indicate the recolonization of areas like the Annapurna Conservation Area and the Tinjure–Milke–Jaljale forests by dholes.
- Despite some optimism among conservationists, challenges such as competition with other predators, habitat fragmentation and human-wildlife conflict persist, requiring further studies and monitoring efforts.
Cornell receives $35m gift for research at nexus of wildlife and health
- Our newfound global awareness that human health, animal health and the health of the planet are inextricably linked has underscored the importance of research at the interface of wildlife and health.
- Cornell University’s College of Veterinary Medicine has announced a donation of $35 million to support its work in this burgeoning field of research.
- The Cornell K. Lisa Yang Center for Wildlife Health aims to use the funds to further its research on how disease interactions affect wildlife, domestic animal and human health, and translate its findings into policy and action to protect wildlife and wild places.
‘Healthy humans without a healthy planet is a logical fallacy’: Interview with Dr. Sakib Burza
- Brought up watching nature’s grandeur in Indian Kashmir, Dr. Sakib Burza’s early inspiration in medicine began at home before he went on to work with Indigenous and local communities in tropical forest regions.
- Having worked in communities responding to the impacts of droughts and climate shocks, he says improved planetary health is crucial for better human health, and that health problems are often the symptoms of climate change or environmental problems.
- At Health In Harmony, he leads medical projects with rainforest communities through the concept of radical listening and supporting their medical needs and livelihoods.
- In an interview with Mongabay, Dr. Burza lays out his argument for how and why the health of people and the planet are connected, and actions that can improve the state of both.
In Argentina, scientists scramble to study seal colonies hit hard by avian flu
- A powerful strain of the avian flu has swept through seal colonies in southern Argentina, wiping out many juvenile populations and raising concern about a spread to other species.
- The flu, also known as H5N1, appeared in Argentina in August 2023 and resulted in newborn mortality rates of over 90% in some seal colonies.
- Researchers are monitoring colony population trends and trying to better understand how the disease jumps from one species to another, which could affect other mammals like orcas.
Civil-backed proposal seeks to address root causes of Thailand’s choking haze
- Policymakers in Thailand have begun proceedings on a new Clean Air Act to address seasonal air pollution that blankets parts of the country every dry season, presenting what experts describe as severe health risks for citizens.
- Agricultural burning and industrial emissions, both locally and in neighboring countries, are the main sources of air pollution levels that annually exceed WHO safe limits, often making Thailand among the most polluted places in the world.
- Several draft versions of clean air legislation have been presented for parliamentary approval, including a citizen-backed proposal that focuses on empowering local action and addressing the root causes of the choking haze.
Prevention is best defense against Bangladesh crop diseases, researchers say
- Two staples — paddy and wheat — and one cash crop, jute, are the major focus areas of researchers and scientists in Bangladesh due to their importance to food security and the economy.
- However, state research institutes say these crops are damaged by five main crop diseases, which could trigger a yield loss of up to 62% annually if outbreaks occur frequently.
- Researchers suggest various approaches, including natural pest control, that could ensure a healthy ecosystem for crop cultivation and reduce the cost of farm production.
Long-term wildlife impacts at Chornobyl, Fukushima may yield ‘a new ecology’
- The world’s worst nuclear power plant accidents to date, at Chornobyl, Ukraine, in 1986, and Fukushima, Japan in 2011, and the human exclusion zones created around them have given scientists a unique opportunity to study the effects on wildlife of radiation and of reduced pressure from people.
- Chornobyl disaster findings regarding the impacts on exclusion zone organisms vary: Some point to a resurgence of the studied wildlife in the absence of humans, while others indicate radiation negatively impacting certain animal populations.
- Fukushima radiation impacts are statistically harder to detect. But scientists have made similar observation to Chornobyl: Some, but not all, species appear to thrive from reduced human pressure.
- Radioactive contamination moves in ecosystem-specific ways, depending on factors such as water flow. A combination of radioactive contamination and reduced human activity in nuclear exclusion zones may be giving rise to “a new ecology,” with nature overall neither suffering nor thriving, simply different in the impacted areas.
Peru’s crackdown on illegal gold mining a success, but only briefly, study shows
- Peru’s state intervention against illegal gold mining in the Madre de Dios region succeeded in halting the activity for a couple of years, pushing miners into concessions allowing mining, according to recent research.
- Operation Mercury, which ran between 2019-2020, led to the abandonment of almost all targeted illegal mining sites in La Pampa, an area found in the buffer zone of a major national park.
- But while there’s been some forest regeneration in the affected areas since then, this has been undone by even higher rates of deforestation in the legal mining areas where the miners have moved into.
- Experts also say the effort has been unsustainable, as law enforcement in the area has waned and miners have started to come back, with the COVID-19 pandemic playing a major role in cutting enforcement budgets.
Jamaica battles relentless plastic pollution in quest to restore mangroves
- In recent decades, mangroves in Jamaica have declined rapidly, from about 15,000 hectares (37,000 acres) in the 1970s to about 9,945 hectares (24,574 acres) now.
- Currently there are several efforts to restore mangroves in the island country, as experts recognize the many ecosystem services they provide, including the protection and stabilization of coastlines as human-induced climate change worsens.
- However, restoration efforts face numerous challenges: Near Kingston, the main one is voluminous tides of plastic waste, which can stunt mangrove growth or kill them.
Last of the reef netters: An Indigenous, sustainable salmon fishery
- Reef net fishing is an ancient, sustainable salmon-harvesting technique created and perfected by the Lummi and other Coast Salish Indigenous people over a millennium.
- Rather than chasing the fish, this technique uses ropes to create an artificial reef that channels fish toward a net stretched between two anchored boats. Fishers observe the water and pull in the net at the right moment, intercepting salmon as they migrate from the Pacific Ocean to the Fraser River near present-day Washington state and British Columbia.
- Colonialism, government policies, habitat destruction, and declining salmon populations have separated tribes from this tradition. Today, only 12 reef net permits exist, with just one belonging to the Lummi Nation.
- Many tribal members hope to revive reef net fishing to restore their cultural identity and a sustainable salmon harvest but face difficulties balancing economic realities with preserving what the Lummi consider a sacred heritage.
Fish out of water: North American drought bakes salmon
- An unprecedented drought across much of British Columbia, Canada, and Washington and Oregon, U.S., during the summer and fall months of June through October could have dire impacts on Pacific salmon populations, biologists warn.
- Low water levels in streams and rivers combined with higher water temperatures can kill juvenile salmon and make it difficult for adults to swim upriver to their spawning grounds.
- Experts say relieving other pressures on Pacific salmon and restoring habitat are the best ways to build their resiliency to drought and other impacts of climate change.
Efforts to Control Stray Dogs and Cats Imperiling Madagascar’s Wildlife
Stray dogs and cats pose a significant threat to native wildlife in Madagascar, with studies indicating a decline in native carnivores and lemurs near villages where these stray animals are prevalent. To address this issue, the American NGO Mad Dog Initiative is taking proactive measures. Their approach includes annual campaigns for sterilization and rabies vaccination, […]
Cerro de Pasco: The massive mine poisoning an entire city in Peru
Cerro de Pasco, a city in Peru, has a mining history that dates back almost 400 years to the early Spanish colonial era. In recent decades, the extensive extraction of metals like lead, zinc, and silver has transformed the landscape, with a massive open-pit mine, around 300 meters deep, now overshadowing this city of 80,000 […]
Poisoned for decades by a Peruvian mine, communities say they feel forgotten
- Communities in Cerro de Pasco, Peru, have been living for decades with contamination from mining activities, which has had serious health consequences, ranging from chronic to fatal diseases.
- Repeated environmental samplings have shown that heavy metal levels surpass by hundreds of times national and World Health Organization safe limits; the most recent research by the NGO Source International reveals persistently high levels of contamination in Cerro de Pasco’s waters and soils.
- IQ levels in children living in Cerro de Pasco have been significantly impacted by exposure to heavy metals.
- Both the Peruvian government and Volcan, the mining company operating in Cerro de Pasco, have done little to nothing to remediate contamination and respond to the communities’ pleas for help.
Australia crackdown on climate protesters grows amid fight against gas project
- The Indigenous ancestral land of Murujuga in Western Australia is home to the world’s oldest and largest collection of petroglyphs, which would be partially destroyed by the country’s biggest fossil fuel project, the Burrup Hub, owned by Woodside Energy.
- As the company argues more gas is needed, direct action tactics by protesters, like releasing non-toxic stench gas or painting on art, have erupted across the state, as well as crackdowns by the police who have begun imposing the strongest form of charges on activists — some facing up to 20 years in prison.
- This is on trend with a general increasing intolerance toward environmental protesters in Australia and an uptick in the use of direct action by protesters who feel the time is running out to meet climate targets and protect endangered species.
- Environmentalists and researchers worry the project will endanger marine life through seismic blasting and say studies show it is not necessary to meet the country’s energy needs.
New online map tracks threats to uncontacted Indigenous peoples in Brazil’s Amazon
- Mobi, a new online interactive map, draws information from public databases, government statistics and field observations to paint a comprehensive picture of the threats that uncontacted Indigenous peoples face in the Brazilian Amazon.
- The exact location of uncontacted communities is deliberately displaced on the map to avoid any subsequent attacks against them from those who engage in illegal activity in or near their territories.
- The tool can help Indigenous agencies deploy more effective protective actions to fend off threats such as diseases and environmental destruction, which can wipe out vulnerable populations.
- Activists hope the platform will help create a vulnerability index that ranks uncontacted populations according to the severity of threats against them, which can promote stronger public policies.
PFAS ‘forever chemicals’ harming wildlife the world over: Study
- While the health impacts of toxic per- and polyfluoroalkyl chemicals, or PFAS, are well known in humans, a new study reports how they affect a wide range of wildlife species.
- In this survey of published studies, the authors found and mapped wildlife exposures worldwide, including impacts on animal species in remote parts of the planet, including the Arctic.
- Researchers documented serious PFAS-triggered conditions in wildlife, including suppressed immunity, liver damage, developmental and reproductive issues, nervous and endocrine system impacts, gut microbiome/bowel disease and more. PFAS pose yet another threat to already beleaguered global wildlife.
- National governments have done little to restrict use of PFAS or remediate pollution, despite growing evidence of increased harm to both humans and wildlife. The study authors call for immediate action to remediate PFAS-contamination sites and regulate industrial chemicals to help protect threatened and endangered species.
Do virus-detecting ants hold the key to preventing zoonotic diseases?
- Researchers are using army ants in Congo Basin rainforests to better understand the presence and emergence of zoonoses, diseases transmitted from animals to humans.
- According to the World Health Organization, the number of zoonotic epidemics recorded in Africa between 2012 and 2022 rose by 63% compared to the previous decade.
- Researchers collected 200 army ants from 29 colonies in Gabon’s rainforest for analysis. They found nearly 50,000 different viral sequences, half of them belonging to viruses currently unknown to science.
- They hope that by regularly collecting ants for analysis from selected sites, they will be able to identify potentially-dangerous viruses as well as which animal species harbour them, and use this information to guide public health strategy to control zoonotic diseases.
‘All will be well’: Q&A with Kenyan fisher turned coral gardener Katana Ngala
- Once a fisherman, Katana Ngala has been restoring corals near his home in Kuruwitu, Kenya, for more than 20 years.
- Early on, the area’s coral was degraded due to destructive fishing practices and coral bleaching, and he and other fishermen were experiencing diminished catches.
- Now the coral and fish are flourishing in the area, which the local community set aside as a no-fishing zone.
- Ngala spoke about the changes he’s seen in the coral garden over time and how he shares his commitment to the sea with fishers, students, scientists and the wider community in an interview with Mongabay at his seaside coral workshop.
Zika, dengue transmission expected to rise with climate change
- A new study foresees a 20% increase in cases of viruses like dengue, Zika and chikungunya over the next 30 years due to climate change.
- Higher temperatures are already causing the diseases carried by the Aedes aegypti mosquito to spread in cooler regions like southern Brazil and southern Europe.
- Deforestation also favors the spread of these illnesses because biodiversity-rich forests with more predators tend to inhibit mosquito populations.
- Brazil set a historic record in 2022, when more than 1,000 deaths resulting from the dengue virus were reported.
Kenyan fishers put new twists on an age-old marine conservation system
- Over the past two decades Kenyan fishing communities have been setting up no-fishing zones called tengefus, Swahili for “set aside.”
- The idea was inspired by the fishing habits of their forebears, who prior to colonization established seasonal fishing closures to ensure plentiful harvests.
- Today there are 22 tengefus in various stages of development in the country, some more successful than others.
- Successful tengefus have seen fish populations and coral cover increase, and they’ve established tourism enterprises that fund community initiatives. To work, experts say tengefus need support from communities, donors and the government.
Nepal’s climate change adaptation strategy needs One Health approach (commentary)
- It is expected that climate change will adversely affect Nepalese biodiversity, human well-being, and economy, from a retreat of glaciers, agricultural losses, and impacts on tourism.
- The spread of infectious diseases can also be fueled by rising temperatures and shifting precipitation patterns.
- “Given the simultaneous exposure of animal and human populations to climate change impacts such as floods and landslides, proactively preparing for and combating ensuing issues like epidemics are best tackled using an integrated One Health approach,” a new op-ed argues.
- This article is a commentary. The views expressed are those of the authors, not necessarily Mongabay.
Prickly babies: A Jamaican nursery aims to restore sea urchins felled by disease
- The long-spined sea urchin (Diadema antillarum) is a key algae grazer in the Caribbean. A disease outbreak in the 1980s killed off most of the urchins, resulting in the overgrowth of many Caribbean coral reefs with algae.
- Last year, a recurrence of the disease hampered the species’ slow recovery. This time, scientists were able to discover the culprit, which they revealed in a recent paper.
- The waters of Jamaica’s Oracabessa Bay Fish Sanctuary remained largely unaffected by the disease. Scientists there collected healthy long-spined sea urchins and started an urchin nursery in hopes of restoring the species on reefs around the island.
- This story was produced with support from the Pulitzer Center.
Citizens demand sustainable solution to haze crisis in northern Thailand
- Citizens in northern Thailand have mounted a legal challenge against the prime minister and several government departments for inaction to tackle air pollution that experts say reduces people’s life expectancy and violates basic human rights.
- Air pollution levels in the northern city of Chiang Mai exceeded WHO guideline standards more than twentyfold earlier this year, ranking it among the most polluted places in the world.
- The sources of pollution are mainly from agricultural burning, both locally and in neighboring countries, a practice that coincides each year with the dry season. Air quality is also affected by forest fires that have taken a toll on the region’s landscapes and wildlife in recent years.
- Observers say the legal challenge is an example of civil society’s growing awareness of the right to use litigation avenues to hold companies and government departments accountable to their environmental commitments.
Bangladesh’s vultures still threatened by poison despite conservation actions
- The discovery of 14 dead vultures in an area of Bangladesh considered safe for the scavenging birds has highlighted the persistent threats to the birds despite ongoing measures to protect them.
- The vultures are thought to have died after feeding on a goat carcass laced with poison, which local residents had left out for feral dogs and jackals that had killed their livestock.
- Vulture populations across South Asia were decimated in the 1990s by the widespread use of the cattle painkiller diclofenac; birds that fed on dead cattle that had been treated with the drug died of severe poisoning.
- Bangladesh has since banned diclofenac and ketoprofen, another livestock painkiller deemed poisonous to vultures, and established vulture-safe zones around the country in an effort to boost their populations.
Parasites of the Caribbean: Study pinpoints cause of sea urchin die-off
- Once abundant in the Caribbean, long-spined sea urchins (Diadema antillarum) experienced a mass die-off in the early 1980s, contributing to coral reef deterioration.
- Another die-off occurred in 2022, leading to a further decline in coral reef health in some parts of the Caribbean.
- A new study has identified the culprit: a parasite called a ciliate that took over the sea urchins’ bodies and quickly killed them.
- While researchers are still trying to determine how this disease is transmitted, they say it’s possible that climate change played a role.
DRC’s endangered bonobos face another threat to their survival: malaria
- Along with humans, great apes like gorillas and chimpanzees are known to get infected with malaria, but evidence about the parasite’s effects on bonobos has been scant.
- A recent study that analyzed the feces of bonobo across the species’ range found that one bonobo population showed evidence of both malaria infection and a genetic variation that would likely protect them against severe disease.
- This genetic variation was less common in other populations, suggesting that other bonobo groups could be in trouble if climate change brings malaria-carrying mosquitoes into their habitats.
Is it safe to eat? Bangladesh fish exposed to hormones, antibiotics and toxic waste
- Bangladesh has recently achieved remarkable success in freshwater fish production, with more than 1.25 million metric tons of freshwater fish produced in 2020.
- The use of antibiotics in fish culture and hormones in artificial fish breeding bring into question the safety of Bangladesh’s food supply, as exposure to high levels of these substances can harm human and environmental health.
- Research shows that 88% of fish farmers do not have proper knowledge of antibiotics use, and 81% are unaware of effective chemical dosages in fish farming.
- In addition, toxic industrial wastes containing heavy metals released into the aquatic environment may enter the food chain through biomagnification and may cause various health problems in humans.
Sagarmatha microbes may survive harsh conditions for decades
- Researchers have found microbes on Mount Everest that can survive harsh winds and conditions at some of the world’s highest elevations.
- The research comes at a time when scientists say melting glaciers and permafrost could reawaken viruses and bacteria as the climate warms.
- However, the microbes found on Mount Everest, which were possibly transported by humans through their coughing and sneezing, are unlikely to grow and reproduce, said University of Colorado Boulder scientist Steve Schmidt, a co-author of a new study on the team’s findings.
Bearded pigs a ‘cultural keystone species’ for Borneo’s Indigenous groups: Study
- A recent study examined the impacts of ecological and sociocultural influences on bearded pig populations in Malaysian Borneo.
- The researchers found that the presence of pigs is “compatible” with Indigenous hunting in certain areas.
- The team’s findings point to the importance of a nuanced understanding of nearby human cultural values and local ecology in determining policies toward hunting.
‘Plasticosis’: the new disease killing seabirds and likely many other species
- Scientists have identified a new fibrotic disease called “plasticosis” in flesh-footed shearwaters, a species that inadvertently consumes plastic.
- They found that plasticosis was even present in shearwaters with only a small quantity of plastic in their stomachs.
- While this plastic-related disease has thus far only been identified in flesh-footed shearwaters, experts say that nearly every organism — including humans — is being impacted by plastic in some way.
SE Asia’s COVID legacy is less wildlife trade, but more hunting, study finds
- The wildlife origins of COVID-19 highlighted the risks of intruding into forests and consuming wildlife, but most discussions around the pandemic have focused on human health and wildlife conservation.
- A recent study investigated how the pandemic impacted hunting communities in Southeast Asia, a hotspot for wildlife hunting and trafficking.
- The results show that while there was a decrease in the wildlife trade as international borders were closed and people’s movements restricted, there was an increase in forest visits and hunting in these communities due to job losses and increasing prices of goods.
- The researchers suggest that to conserve wildlife in the region and rein in hunting, authorities need to work with hunting communities and support sustainable alternative livelihoods.
For tigers in Nepal, highways are a giant roadblock best avoided
- A new study indicates that the presence of roads, and vehicle traffic, in tiger habitats could take a toll on the big cats’ behavior and long-term fitness and survival.
- A tiger fitted with a GPS collar in Nepal’s Parsa National Park was found to avoid crossing roads by day, but to cross more often during the country’s 2021 COVID-19 lockdown.
- This suggests the animals can adapt quickly when traffic volume eases, pointing to measures that can be taken to mitigate road impacts not just on tigers, but on wildlife in general.
- Researchers say the findings should give planners in Nepal something to consider as they look to double the number of lanes on the East-West Highway that runs through both Parsa and Bardiya national parks.
Deforestation could pose disease threat to Amazon’s white-lipped peccaries
- White-lipped peccaries are vital ecosystem engineers and an important source of food for people living in the Amazon.
- Deforestation has reduced their habitat and, in addition, researchers highlight that disease is an understudied factor in their conservation.
- Scientists say it could represent an additional threat to an already vulnerable species, as continuing deforestation and expanding agricultural frontiers can bring greater contact between domestic animals and wildlife, potentially leading to spillover events.
Avian flu hits Peru, killing thousands of sea birds and infecting some marine mammals
- H5N1, a highly pathogenic avian influenza virus carried generally by wild birds, has arrived in Latin America, causing unprecedented mortality in sea bird colonies along the west coast.
- The virus has killed tens of thousands of sea birds in Peru alone, including some species that are considered endangered in the country, and scientists worry other vulnerable species like the Andean condor might also become infected.
- Hundreds of sea lions and a dolphin have also been infected, which raises concerns regarding transmission to humans and is especially worrisome if it is confirmed that mammals can infect each other.
- The outbreaks also threaten Peru’s guano industry, which provides affordable fertilizer to many small-scale farmers in the region, and could expose people harvesting guano to H5N1.
In Nepal, conservationists suspect link between canine distemper and human-leopard conflict
- A new study shows for the first time that leopards in Nepal are exposed to canine distemper virus.
- Researchers suggest the virus could make the big cats less fearful of humans and thus more likely enter settlements in search of food.
- Conservationists have long warned of the risk of feral dogs passing on diseases like canine distemper to wildlife in Nepal, including tigers and leopards.
- Other studies show that while initial infections may have come from dogs, multiple strains the virus are now circulating among wildlife, making the latter carriers too.
Restore linked habitat to protect tropical amphibians from disease: Study
- Amphibians across the tropics are facing a global decline, with disease caused by the chytrid fungus Batrachochytrium dendrobatidis (Bd) playing an especially significant role in losses.
- According to recent research, “habitat split” — when different types of habitat, such as terrestrial and freshwater areas, become separated — could play a role in exacerbating disease, potentially altering species’ microbiomes and weakening amphibian resistance.
- According to the study, an amphibian’s journey through altered habitat to complete its life cycle can change the composition of its microbiome (the bacterial makeup of the skin); induce chronic stress; and reduce immune gene diversity — all of which can impact disease resistance.
- Though further studies are needed, this research may offer another persuasive reason to actively restore and reconnect habitats, helping to “prime” amphibian immune systems against disease. There is also a possibility that habitat split findings among amphibians could extend to other families of animals.
Pollution and climate change set stage for rise in antimicrobial resistance
- A new report from the United Nations Environment Programme illustrates the role that pollution, climate change and biodiversity loss can play in the development of antimicrobial resistance.
- The compounds used to treat bacterial, viral, parasitic and fungal infections have saved countless lives, but their overuse and their presence in the environment from human waste, agriculture and effluent from the pharmaceutical industry and places like hospitals has given rise to resistance to these chemicals in potentially harmful microbes.
- If this resistance continues to increase, experts warn that an additional 10 million people may lose their lives by 2050 — about the same number who died of cancer in 2020.
- The report’s authors recommend stronger safeguards around industrial runoff, better sanitation and more judicious use of antimicrobials to address this potential crisis.
Pollinator declines linked to half million early human deaths annually: Study
- A new modeling study finds that half a million people are currently dying prematurely every year due to global insect pollinator decline because of lack of availability and/or high price of healthy foods such as nuts, legumes, fruits and vegetables.
- Robust epidemiological research has linked higher fruit, vegetable and nut intake to lowered mortality from many major chronic diseases like heart disease, stroke, cancer and diabetes.
- Researchers assessed the problem nationally: Middle-income countries, including Russia, China and India, are among the hardest hit, as are Indonesia, Vietnam and Myanmar, though surprisingly, parts of Latin America and sub-Saharan Africa were among the least affected. Wealthy nations were more immune from pollinator decline.
- Experts say multiple solutions are readily available: Wild pollinators can be significantly increased by protecting existing, and creating new, pollinator habitat at the farm and national level, by reducing and eliminating the use of harmful pesticides like neonicotinoids, and by effectively combating climate change.
Yanomami health disaster prompts outrage as Lula vows to tackle crisis
- An average of three Indigenous Yanomami infants have died every week over the past four years in Brazil from diseases that are considered treatable, an investigation shows alongside shocking pictures.
- Experts say that decades-long invasions by illegal miners in the Yanomami Indigenous Territory and the dismantling of health care systems under the administration of Jair Bolsonaro have caused a spiral of malnutrition and disease within the Yanomami population.
- Official complaints from Indigenous rights advocates and allies from at least 2018 have been systematically ignored, leading to a worsening of the problems.
- Brazil’s new president, Luiz Inácio Lula da Silva, has called the crisis a genocide and vowed to tackle the problem with a series of immediate and long-term action plans.
As sea lice feast away on dwindling salmon, First Nations decide the fate of salmon farms
- Increased sea lice infestations, scientists say are caused by salmon farms, threaten the already-vulnerable wild Pacific salmon populations in western Canada, worrying conservationists and First Nations.
- Three First Nations in the region are now deciding on the future of open net pen Atlantic salmon farms dotting the channels and waterways in and around their territories. They hope their decisions will pave the way to protect wild salmon, a culturally important species.
- So far, ten farms have been closed and the future of seven farms are to be decided this year, in 2023.
- The impact of the closure of the farms on local sea lice and wild salmon populations is still unclear, say scientists, and more time to monitor the data is needed.
Himalayan community takes initiative to help dogs, wildlife and itself
- Feral dogs have long proved problematic to people, livestock and wildlife in Nepal’s Annnapurna region.
- Studies have shown a high prevalence of canine distemper among the dogs, which are also suspected of carrying other diseases that could be passed on to domestic animals, wildlife or even people.
- A project to vaccinate and neuter the dogs helped slow their population growth, but was halted by the COVID-19 pandemic.
- Since then, however, locals have revived the initiative on their own, and the success of their efforts have drawn requests for assistance from other Himalayan communities dogged by dogs.
Shadows of oil in Peru: Shipibo people denounce damage, contamination left by company
- Community members guided a team of journalists to the creeks and land of Canaán de Cachiyacu and Nuevo Sucre, in the district of Contamana in Peru’s Loreto region, to demonstrate how they have been affected by the various spills attributed to the Maple Gas oil company for over 25 years.
- Shipibo community members say that due to contaminated water, they still suffer from illnesses and their farms no longer produce crops. The contract established that the company must comply with environmental protection laws, but Perupetro confirmed that it simply abandoned its operations.
- Mongabay Latam traveled to two Indigenous communities on the banks of the Ucayali River and listened to the concerns of their residents regarding the serious environmental impact that they claim was caused by the operations in Block 31-B and Block 31-E.
Tobacco: Vaping and smoking drive environmental harm from farm to fingertip
- Electronic cigarettes heavily marketed via single-use flavored products are increasingly popular. These products require disposal of large amounts of hazardous waste, including huge quantities of lithium, a resource in demand for electric car batteries and rechargeable electronics for laptops and mobile phones.
- Even as vaping use grows, an estimated 6 trillion “traditional” cigarettes are still smoked annually; 4.5 trillion are thought to be discarded into the environment each year. Researchers and activists emphasize that the tobacco industry is responsible for considerable harm to nature and human health.
- Traveling along the supply chain, tobacco production and consumption has consequences for forests, oceans, the climate, and for farmers and their families who produce the crop — all to an extent not yet fully known or understood.
- Efforts are underway to rein in some of these negative impacts against the backdrop of an industry accused of consistently greenwashing to conceal an environmental footprint that is harming both nature and public health.
Ebola-like African primate viruses ‘poised for spillover’ to humans, study finds
- A family of viruses that causes Ebola-like symptoms in African primate populations is “poised for spillover” to humans, a new study shows.
- Researchers say these arteriviruses, already a threat to macaques, use a specific receptor to enter and invade the body; humans have a similar form of the receptor, called CD163.
- Although there is no evidence of these viruses infecting humans to this point, researchers say they found similarities to the viruses that gave rise to HIV.
- Conservationists say the risks of animal-human disease transmission increase as human populations continue to encroach on wild animal spaces.
“Sinchiurco is coated with oil”: The Kichwa people going up against Petroecuador
- In 1985, a road opened through the Kichwa community of Sinchiruco, in the northern Ecuadorian Amazon. With it came the Guanta 1 oil platform, which would lead to repeated complaints of human and environmental rights violations.
- Until 1990, Guanta 1 was operated by Texaco. Texaco and the companies that came later have been accused of oil and diesel spills, creating crude oil pools, and accidents that led to the death of a child and the loss of one girl’s sight.
- The platform was later managed by Petroamazonas and PDVSA. Now run by Petroecuador, the surrounding communities are still demanding compensation for previous spills and repairs to partially fixed pipelines that, they claim, continue to cause spills. After 37 years, the community is saying that enough is enough.
Indigenous youths lured by the illegal mines destroying their Amazon homeland
- An increasing number of young Indigenous people in Brazil’s Yanomami Indigenous Territory are leaving their communities behind and turning to illegal gold mining, lured by the promise of small fortunes and a new lifestyle.
- Work in the mining camps ranges from digging and removing tree roots to operating as boat pilots ferrying gold, supplies and miners to and from the camps; recruits receive nearly $1,000 per boat trip.
- The structures, traditions and health of Indigenous societies are torn apart by the proximity of the gold miners, and the outflow of the young generation further fuels this vicious cycle, say Indigenous leaders.
- Amid the COVID-19 pandemic and a lack of authorities monitoring the area, illegal mining in the region has increased drastically, with 20,000 miners now operating illegally in the territory.
Dhaka’s ailing sewage system threatens human and environmental health
- Existing sewage treatment plants in Dhaka treat only 30% of all sewage waste.
- Emerging pollutants such as antibiotics, microplastics, detergents, toothpastes, shampoos and lotion are found in Dhaka’s urban rivers and lakes.
- Microplastics are also found in fish, snails, crabs and sediments of the Buriganga River in Dhaka.
- City authorities suggest installing small treatment plants in residential buildings.
In Bangladesh, popular eggplant comes with a side of lead. And cadmium
- New studies have highlighted potentially cancer-causing levels of chemicals such as lead and cadmium in food crops grown across Bangladesh, and in particular in eggplants, one of the most widely consumed vegetables in the country.
- Researchers attribute the contamination to excessive use of chemical fertilizers and pesticides by farmers, as well as industrial pollution.
- Also affected are fish caught in the Buriganga River in the capital, Dhaka, and cow’s milk sold in the city.
- Regulators have acknowledged the problem, and say they’re working on efforts to reduce agrochemical use across the country and crack down on industrial pollution.
Probe finds Vietnam faltering in bid to curb wildlife trade, animal suffering
- In recent years, authorities in Vietnam have made a series of pledges to curb illegal wildlife trade and the sale and consumption of dog meat.
- However, a new investigation by animal rights groups reveals that protected wildlife species are still being sold at wet markets, where animal suffering and public health risks are rife.
- The findings also indicate the dog meat industry shows few signs of abating, with slaughterhouses and restaurants still doing business despite calls to phase out the industry in major cities.
- Experts say sustained and coordinated efforts from provincial authorities, enforcement agencies and the public will be needed to fully curb the practices throughout the country.
Another winter of discontent as Kathmandu braces for deadly air pollution
- As winter sets in, residents of Kathmandu are bracing for worsening air pollution levels that can exceed by a hundredfold the safe limit prescribed by the WHO.
- The sources of the pollution are both local — vehicle exhaust fumes and burning of garbage — and from further afield, including firecracker residue from festivities in neighboring India.
- A recent study says these combine to give Nepal the highest death rate from chronic lung disease of any country — a problem that experts say the government has repeatedly failed to recognize.
Who let the dogs out? Feral canines pose a threat to Nepal’s wildlife
- Dogs in Nepal enjoy a special status during the Tihar festival, but for the rest of the year are often overlooked or even abandoned.
- The latter often turn feral and pose a threat to the country’s iconic wildlife — from tigers to snow leopards to dholes — through potential disease transmission and competition for prey.
- Studies show a high prevalence of diseases such as canine distemper and parvovirus among dogs near key protected areas.
Conservationists say it’s up to humans to better manage their pets, including vaccinating them routinely, sterilizing them, and not abandoning them.
In temperate Nepal, climate change paves way for tropical dengue fever
- Nepal is experiencing its worst outbreak of dengue fever in recorded history, which health experts attribute in part to a changing climate.
- Wetter monsoons and warmer temperatures have made for ideal breeding conditions for the mosquitoes that carry the virus.
- Poor water and waste management are also factors, allowing for water to stagnate for long periods and giving the mosquitoes a place to lay their larvae.
- Experts say it will take a combination of personal responsibility — to eradicate mosquito-breeding grounds — and government leadership — to coordinate the public health response — if dengue is to be eradicated in Nepal.
Severe malaria cases in rescued orangutans raises concerns for wild populations
- Researchers in West Kalimantan, Indonesia, sampled orangutans and found a high prevalence of malaria.
- In some cases, malaria resulted in severe illness among the great apes, causing concern about the conservation implications for the animals.
- On the plus side, all of the orangutans inflicted with severe illness responded well to treatment and recovered.
- Some experts says these findings underline the need for a precautionary principle when translocating or reintroducing orangutans that test positive for malaria.
Wild cats threatened by ‘underrecognized’ risk of spillover disease
- Researchers warn that disease spillover from livestock and domestic animals represents a serious conservation threat to wildlife, including felids in tropical areas around the world. Spillover is most likely to occur on rapidly advancing forest-agricultural frontiers or within fragmented habitats.
- Tracking the spillover and spread of diseases from humans and domestic animals to wildlife is extremely challenging, particularly among wild felid species, which tend to be secretive and solitary, making ongoing observation difficult.
- Possible cases of disease spillover have been documented in wild cats in India, Malaysian Borneo, Thailand, Brazil, Ecuador, Costa Rica, Russia and Nepal. These are likely the tip of the iceberg, say scientists, who believe much disease among wild species is going undetected, with case numbers and outbreaks unknown.
- Scientists stress the need for greater health monitoring of wildlife to reduce this “invisible threat.” But funding for health testing is often scant, and treatment difficult. One researcher sees disease transmission from domestic animals to wildlife as perhaps the most “underrecognized conservation threat today.”
‘Remix it and let it evolve’: Q&A with FieldKit developer Shah Selbe
- Conservation technologist Shah Selbe’s plan to unveil his new environmental sensor platform FieldKit went awry because of the COVID-19 pandemic and the subsequent global supply chain crisis.
- The supply chain crisis has impacted companies big and small across industries — from Ikea to McDonalds — and been particularly harsh on smaller operators like Selbe, who don’t have the purchasing might of tech giants like Apple that are scrounging for the same scarce components.
- Selbe says that while the situation has improved somewhat, it’s still going to be hard on the conservation technology community: “Don’t build a hardware product during a pandemic,” he laughs.
- He also emphasizes the need for conservation technology to be open source to promote sharing of information: “I want people to be able to take FieldKit and mix and match and create some version of their own and build on it.”
For Brazil’s Indigenous people, slavery born of colonization still hasn’t ended
- Since Brazil began recording cases of workers found working in slavery-like conditions in 2004, 1,640 Indigenous people have been rescued from these situations.
- During the COVID-19 pandemic, more than 100 Indigenous people have been found working in these conditions.
- Sugarcane harvesting, which a decade ago was the worst offender in terms of enslaved Indigenous laborers, has now been eclipsed by apple harvesting in the states of Rio Grande do Sul and Santa Catarina, where native peoples endure degrading work conditions.
- Mato Grosso do Sul in Brazil’s south is the state where the most people have been rescued, but numbers of Indigenous slaves are rising in the Amazon in the north, especially at the illegal mines operating inside the Yanomami Indigenous Territory.
Farmer-to-farmer agroecology: Q&A with Chukki Nanjundaswamy of Amrita Bhoomi Learning Centre
- The Amrita Bhoomi Learning Centre in southern India is one of dozens of education hubs around the world providing a space for farmer-to-farmer training in agroecology.
- In a wide-ranging interview with Mongabay, the center’s Chukki Nanjundaswamy discusses their model of agriculture, its Gandhian roots, and how it grew out of the rejection of Green Revolution farming techniques that rely on chemical inputs and expensive hybrid seeds.
- Nanjundaswamy shares some of their innovative approaches to growing food without inputs, plus clever techniques to thwart notorious pests like fall armyworm, which is also prevalent in Africa.
For residents of Jakarta’s port district, coal is the neighbor no one wants
- Residents, officials and experts blame dust from a coal storage facility in Jakarta’s port district for a spate of health problems in a neighboring community.
- Children in Marunda ward have been hit particularly hard, suffering from eye and skin problems and respiratory infections, in a city already notorious for its dirty air.
- City authorities inspecting the facility run by KCN, a public-private joint venture, have found several violations and revoked the company’s environmental permit.
- While KCN has offered to provide residents with free medical checkups, it has not acknowledged a link between its operation and residents’ health problems.
WTO finally nets deal curbing fisheries subsidies, but tables key bits for later
- Negotiators agreed on a deal to curb “harmful” government fisheries subsidies that are compromising fish populations and damaging the marine environment.
- The talks among the World Trade Organization’s 164 member states were scheduled for June 12–15, but overtime negotiations didn’t conclude until early June 17.
- The new agreement addresses certain harmful subsidies. But in the interest of reaching consensus, negotiators put off dealing with others where agreement proved elusive.
- Many observers are welcoming the agreement as “historic,” coming as it does two decades after talks began in 2001, even as others point out “major weakness.”
Farmers in Mexico fight coffee disease with resistant varieties and agroforestry
- Indigenous Mixe farmers in Mexico’s Sierra Norte highlands are testing dozens of coffee varieties and developing agroforestry systems in order to combat coffee leaf rust, a fungal disease that spread to the region and devastated coffee production.
- The parasitic fungus thrives in wet and warm temperatures, say researchers, which are becoming more frequent in Mexico’s highlands amid changes in climate.
- The project tests the resistance of over 27 different varieties of coffee within a shaded agroforestry system that helps decrease temperatures and create drier conditions – reducing the fungi’s spread.
- Cultivating organic coffee in times of unpredictable weather is risky, costly and a laborious exercise. The cost of production is also growing, affecting farmers’ eagerness and capacity to cultivate.
At 30, Brazil’s Yanomami reserve is beset by mining, malaria and mercury
- When the Yanomami Indigenous Territory, the world’s biggest, was designated 30 years ago, the Brazilian army cleared out the illegal gold miners operating there.
- Today, miners are back in force, encouraged by the anti-Indigenous and anti-environment rhetoric of President Jair Bolsonaro, who has vowed to open up the reserves to mining.
- The illegal activity has destroyed forests and contaminated rivers with mercury and has also brought with it violence, disease and death for the 27,000 Yanomami living in the heart of the Amazon.
- As it marks the 30th anniversary of its establishment, the Yanomami reserve faces of the prospect of losing up to a third of its area to mining — a very real prospect if a key Bolsonaro bill clears Congress.
Study warns of risk from feline viruses to wild cats on the palm oil frontier
- A recently published study has found that wild felines are exposed to viruses common to domestic cats, such as feline coronavirus.
- Certain species that frequent oil palm plantations in Malaysian Borneo, such as the leopard cat and Malay civet, may act as carriers of viruses back into forest areas.
- These findings are of concern, conservationists say, due to the potential impact on threatened small cat species, such as the endangered flat-headed cat and the vulnerable Sunda clouded leopard.
- Integration of animal welfare into conservation action and oil palm management plans are potential solutions to mitigate the risks of transmission, the study authors say.
Tale of two pandemics as mining thrived while communities faced restrictions
- The power imbalance between mining companies and communities in Latin America deepened during the COVID-19 pandemic, according to a report published May 24.
- The report details how the pandemic presented companies with a window of opportunity to continue or even ramp up their activities, while communities opposed to mining projects faced pandemic restrictions and violence.
- Indigenous Mapuche-Tehuelche community leaders from Argentina traveled to Guatemala in May to meet with Indigenous Xinka communities affected by the same mining company.
Rachel Carson’s ‘Silent Spring’ 60 years on: Birds still fading from the skies
- Rachel Carson’s “Silent Spring” catalyzed the modern environmental movement and sparked a ban on DDT in the U.S. and most other nations, though DDT has since been replaced by a growing number of other harmful biocides.
- Now, 60 years later, birds may face more threats than any other animal group because they live in — or migrate through — every habitat on Earth. Birds are impacted by land-use changes, pollution (ranging from pesticides to plastics), climate change, invasive species, diseases, hunting, the wildlife trade, and more.
- The 2022 update to the “State of the World’s Birds” report notes winners and losers amid increasing human alteration of the planet, but documents a continuing downward trend.
9m deaths a year from pollution, the ‘largest existential threat’ to humans
- A new report has found that pollution is responsible for 9 million premature deaths per year, the majority of them caused by air pollution.
- While deaths associated with household pollution and water quality have decreased, deaths related to industrialization and urbanization have increased.
- It’s estimated that lead and other chemical pollutants are responsible for about 1.8 million deaths, but the authors say this is likely to be an undercount.
- The authors argue that more needs to be done to address the issue of pollution, which would also help mitigate the impacts of climate change.
Wage-related abuses in fishing industry exacerbated by pandemic response
- The COVID-19 pandemic left migrant fishers in Asia, already a highly vulnerable section of the workforce, with less income and at higher risk of labor abuses, a new report says.
- The brief, commissioned by the International Labour Organization and authored by Cornell University researchers, looked at workers’ experiences in the fishing and seafood-processing industries of Japan, South Korea, Thailand and Taiwan from March 2020 to March 2021.
- Common issues they uncovered included employers paying wages below the legal minimum, making illegal wage deductions, deferring wage payments, and not paying wages upon termination of employment.
- Labor shortages caused by border closures due to the pandemic should have given workers more leverage in wage negotiations, but this wasn’t the case, the researchers found.
Conservation win for Bangladesh as efforts to halt vulture decline pay off
- Concerted conservation actions since 2010 have helped halt the decline in vulture populations in Bangladesh.
- The country was previously home to seven vulture species, but one — the red-headed vulture (Sarcogyps calvus) — has now gone locally extinct, and two others are considered critically endangered.
- A key threat to the birds was the excessive use of veterinary drugs used in cattle, which proved deadly for the scavengers, but which have since been banned.
- Bangladesh has also declared several “vulture safe zones” across the country, where officials work with local communities to raise awareness about the importance of vultures to the environment and to protect breeding sites and habitats.
Thai gold mine blamed for sickening local villagers is set to reopen
- The Chatree mining complex, owned by a subsidiary of Australia’s Kingsgate Consolidated Ltd., began operations in 2001 and was closed by Thailand’s ruling junta in 2017.
- Villagers say the environment and their health has suffered as a result of the operations; mass blood tests found that the majority of children and adults tested exhibited elevated levels of heavy metals, including arsenic, manganese and cyanide.
- The mining company denies allegations that its operations have caused health problems, and in 2017 sued the Thai government for shutting down the mine, seeking “very substantial damages.”
- In January 2022, the government gave permission for the mine to reopen.
Illegal miners bring sexual violence and disease to Indigenous reserve in Brazil
- A new investigative report shows that Brazil’s largest Indigenous reserve is experiencing the most intense spate of invasions by illegal miners in 30 years.
- An estimated 15,000 of the Yanomami Indigenous Territory’s Indigenous inhabitants have been directly affected by the mining, with girls as young as 11 lured into sex work with the promise of food and clothing.
- The miners are also exploiting Venezuelan refugees fleeing the economic crisis in their country, effectively keeping them in indentured labor through insurmountable debts.
- Forest destruction as a result of illegal mining has nearly tripled since 2018 inside the Yanomami reserve; the practice has also been blamed for outbreaks of malaria and high rates of child malnutrition.
Study finds high prevalence of gut parasites in Nepal’s rhinos
- A high prevalence of tapeworms and other parasites in the greater one-horned rhinos of Chitwan National Park in Nepal has raised concerns about the threatened species.
- A new study suggests the problem is an unintended consequence of decades of successful rhino conservation, leading to a growing number of the animals roaming outside the park and into areas also frequented by livestock.
- A similar high prevalence of gastrointestinal parasites has also been recorded in India’s Kaziranga National Park.
- The authors of the new study emphasize that the parasites don’t kill the rhinos, although they may affect their metabolism or cause disease during periods of stress.
Unseen crisis: Threatened gut microbiome also offers hope for world
- Plants and animals provide a home within themselves to an invisible community of microbes known as the microbiome. But these natural microbial communities are being degraded and altered by human-caused biodiversity loss, pollution, land-use change and climate change.
- On the macro level, habitat loss and diminished environmental microbe diversity, particularly in urban environments, is altering the gut microbiomes of humans and wild animals. Studies have linked microbiome changes to higher risk of chronic and autoimmune diseases.
- Coral bleaching is an extreme example of climate stress-induced microbiome dysfunction: During heat waves, beneficial microbes go rogue and must be expelled, leaving the coral vulnerable to starvation. Microbiome resilience is key to determining corals’ ability to acclimate to changing ocean conditions.
- There are solutions to these problems: Inoculating coral with beneficial microbes can reduce bleaching, while the restoring natural green spaces, especially in socioeconomically deprived urban areas, could encourage “microbiome rewilding” and improve human and natural community health.
Bonobos torn from the wild make their return, with a helping hand
- An NGO in the Democratic Republic of Congo has returned 14 bonobos into the wild — only the second time ever a bonobo group has been reintroduced to their natural habitat.
- Friends of Bonobos runs a bonobo sanctuary in the DRC where bonobos orphaned by illegal poaching are tended to and rehabilitated.
- The nonprofit released the first group of bonobos in the Ekolo ya Bonobo Community Reserve in 2009, and after more than a decade of preparation and several delays, the second batch was safely moved into the reserve in March.
- The Ekolo ya Bonobo Community Reserve was officially designated a protected area in 2019, and Friends of Bonobos plans to seek National Park status for the forest. This effort could help ensure the two groups remain safe in the wild.
‘A risky business’: Online illegal wildlife trade continues to soar in Myanmar
- A new report from WWF shows that trade in protected wild animals and their body parts in Myanmar via the social media platform Facebook rose by 74% in 2021 compared to the previous year.
- The scale of the online trade, the purpose of the trade, and the species seen in the trade are all of major concern in terms of impacts on biodiversity and the potential risks to public health from disease transfer, according to the report.
- Posts advertising live civets and pangolins as wild meat, as well as posts referring to their commercial breeding potential are a particular concern, argue the report authors. Both species are considered to be potential vectors in passing zoonotic diseases to humans.
- The report calls on online platforms to do more to monitor their platforms and take swift action, and for greater involvement and collaboration from multiple sectors to strengthen enforcement, disrupt the illegal wildlife trade, and increase awareness of the health risks posed by illegally traded wildlife.
An Indigenous basket-weaving tradition keeps a Philippine forest alive
- Traditional handicrafts like the Pala’wan Indigenous people’s tingkep woven baskets are deeply tied to local ecosystems; experts increasingly understand that supporting traditional practices can aid conservation by creating incentives for keeping forests intact.
- Efforts to support tingkep weavers have been undercut by the COVID-19 pandemic, which has dried up tourism in Palawan as well as reduced disposable income for many potential buyers, dramatically slashing the demand for the handicrafts.
- At the same time, climate change is already affecting the forests from which tingkep weavers gather materials.
Call for COVID rules that reduced infections in gorilla parks to remain
- Respiratory infections recorded among mountain gorillas in Rwanda’s Volcanoes National Park dropped from a pre-pandemic average of 5.4 outbreaks among family groups to just 1.6 per year since the start of the COVID-19 pandemic in March 2020.
- Conservation group Gorilla Doctors, whose Rwanda team recorded the decrease in infections, says the decline correlates with lower visitor numbers to the park as well as masking requirements and an increase in the distance tourists must stay from habituated apes.
- In a recent letter in the journal Nature, Gorilla Doctors and the park’s chief warden called for these stricter measures to be kept in place permanently.
Preventing the next pandemic is vastly cheaper than reacting to it: Study
- A new study emphasizes the need to stop pandemics before they start, stepping beyond the quest for new vaccines and treatments for zoonotic diseases to also aggressively fund interventions that prevent them from happening in the first place.
- Researchers estimated that based on Earth’s current population and on past pandemics, we can expect 3.3 million deaths from zoonotic diseases each year in future. COVID-19 pushed numbers in 2020-21 even higher. These outbreaks are now happening more frequently, and their cost is calculated in trillions of dollars.
- Addressing the main drivers — deforestation, the wildlife trade and burgeoning agriculture, especially in the tropics — could prevent future pandemics, save lives and catastrophic societal disruptions.
Rainforests in 2022: A look at the year ahead
- Between rising deforestation in the Amazon, new financial and political commitments to reduce deforestation, and growing interest in “nature-based solutions” like conservation and reforestation, 2021 may prove to have been a fateful year for the world’s tropical rainforests.
- So what should we expect in 2022? Mongabay Founder Rhett A. Butler provides a brief look at what may be some of the major storylines for tropical forests in the coming year.
- He picks 12 issues to watch, ranging from the post-COVID recovery to carbon markets to geopolitics.
Mongabay’s Top 10 Indigenous News Stories of 2021
- To date, 2021 has proved to be one of the most consequential years for Indigenous rights and participation in global climate and conservation efforts.
- In some parts of the world, Indigenous communities saw support for their rights increase, while in others, threats to their land rights by extractive industries continued unabated.
- To end the year, Mongabay rounds up the top 10 Indigenous news stories of 2021.
Conservation deaths in 2021
- Between the pandemic, natural disasters worsened by human activities, and violence against environmental defenders, 2021 was another year of significant losses in conservation.
- The following is a list of some of the deaths that occurred in 2021 that were notable to the conservation sector.
Mongabay’s top Amazon stories from 2021
- The world’s largest rainforest continued to come under pressure in 2021, due largely to the policies of Brazilian President Jair Bolsonaro.
- Deforestation rates hit a 15-year-high, while fires flared up again, combining to turn Brazil’s portion of the Amazon into a net carbon source for the first time ever.
- The rainforest as a whole remains a net carbon sink, thanks to conservation areas and Indigenous territories, where deforestation rates remained low.
- Indigenous communities continued to be hit by a barrage of outside pressure, from COVID-19 to illegal miners and land grabbers, while community members living in Brazil’s cities dealt with persistent prejudice.
2021’s top ocean news stories (commentary)
- Marine scientists from the University of California, Santa Barbara, share their list of the top 10 ocean news stories from 2021.
- Hopeful developments this year included big investments pledged for ocean conservation, baby steps toward the reduction of marine plastic pollution, and the description of two new whale species, Rice’s whale (Balaenoptera ricei) and Ramari’s beaked whale (Mesoplodon eueu).
- At the same time, rising ocean temperatures, a byproduct of climate change, had profound effects on marine species up and down the food chain, and action on key measures to maintain ocean resilience in the face of multiple threats hung in the balance.

As the Amazon burns, its Indigenous inhabitants choke on the haze
- Forest fires in the Brazilian Amazon increased this year, with much of the smoke generated concentrating in the state of Acre and disproportionately affecting the health of Indigenous people.
- At the peak of the fires, in July and August, a total of 88,400 hectares (218,400 acres) of land burned, a 20% increase from the 76,400 hectares (188,800 acres) burned in the same period in 2020.
- Recorded cases of respiratory disease increased by almost 8% from June to September 2021 over the previous year, according to data from the Acre state health department.
- Indigenous people, who have lower immunity and a higher incidence of pre-existing medical conditions, are among the most at-risk groups to the smoke pollution, compounded by the ongoing COVID-19 pandemic.
What has the pandemic done to forest policies? (commentary)
- Aida Greenbury, the former Managing Director of Sustainability at APP Group and currently a board member and advisor to several organizations including Mongabay, raised concerns about recent high-level commitments from governments.
- Greenbury says that fuzzy definitions on what constitutes “forest” and “deforestation” leave plenty of loopholes for countries to dodge meaningful action on protecting natural forests. She cites Indonesia, where there’s a renewed push to classify industrial oil palm plantations as forests, as an example.
- “Creating vague definitions for ‘forest’ is a common tactic by policy makers and corporations. It could be used to change the perception of deforestation being associated with palm oil,” she said. “Categorizing oil palm plantations as ‘forest’ could be used to lower the country’s official deforestation rate, as well as make them eligible for carbon offsets. It would probably even legalize oil palm plantation development in protected forest areas.”

Lockdown underscores Uganda’s overreliance on tourism to fund conservation
- When the COVID-19 pandemic broke out in March 2020, Uganda quickly shut down parks like Bwindi Impenetrable National Park to protect the gorillas and chimpanzees from getting infected.
- Tourism provides up to 60% of the Uganda Wildlife Authority’s operating revenue and is also an important source of income for communities living around Bwindi.
- Poaching in Bwindi rose sharply during lockdown in 2020 as some villagers entered the park to hunt for food or an income.
- One NGO reinforced its programs supporting public health and livelihoods in an attempt to reduce this pressure.
Uganda’s ‘Dr. Gladys’ honored by U.N. for work linking conservation and health
- The United Nations on Dec. 7 recognized Gladys Kalema-Zikusoka as one of its “champions of the Earth” for promoting the One Health approach to conservation in Africa.
- The Ugandan conservationist, a trained wildlife veterinarian, established the NGO Conservation Through Public Health (CTPH) in 2003 to ensure better health care access for communities living around Bwindi Impenetrable National Park and to lower the risk of human pathogens jumping to mountain gorillas.
- UNEP selected Kalema-Zikusoka for its science and innovation category; the other awardees were Barbados Prime Minister Mia Mottley, Kyrgyz youth activist Maria Kolesnikova, and the nonprofit Sea Women of Melanesia.
- “If you make the community feel that you care about them, then there’s less need to fight them,” Kalema-Zikusoka said.
Illegal mangrove logging surges in Indonesia’s Batam amid economic hardship
- Police in Indonesia’s Riau Islands have reported a 280% increase in seizures of mangrove wood from would-be smugglers this year.
- Police said much of the wood was cut from the main island of Batam, and destined for nearby Singapore and Malaysia.
- Indonesia is targeting the rehabilitation of 630,000 hectares (1.55 million acres) of mangrove forests across the country by 2024.
- The country is home to more than a quarter of the world’s mangroves, an ecosystem that buffers coastal communities against storm surges and sea-level rise, stores four times as much carbon as other tropical forests, and serves as a key habitat for a wealth of marine species.
Latest delay casts pall over WTO bid to end harmful fishing subsidies
- International negotiators were set to discuss ending government subsidies that lead to overfishing at the Twelfth WTO Ministerial Conference, scheduled to run Nov. 30 through Dec. 3 in Geneva, Switzerland.
- Days before it was due to start, however, organizers postponed the event indefinitely, due to concerns over the newly announced COVID-19 variant, Omicron.
- Negotiators have been struggling to close the remaining gaps in an agreement that has been 20 years in the works.
- Observers say the ongoing failure to reach agreement on fishing subsidies calls into question the WTO’s ability to adapt to a changing world and meet the U.N.’s Sustainable Development Goals.
Extinction not only threatens primates—their parasites are in danger, too
- Primates threatened with extinction have highly specific parasites that will likely vanish if their hosts go extinct.
- Parasites play essential roles in ecosystems, but most are so understudied that scientists don’t understand the consequences of losing them.
- If in peril due to a diminishing number of hosts, parasites may try to jump to new host species—potentially triggering unforeseen infections.
Wildlife trade hub Vietnam is also hub of impunity for traffickers, report says
- Only one in every seven wildlife seizures made in Vietnam in the past decade has resulted in convictions, a new report by the U.K.-based Environmental Investigation Agency has found.
- Low numbers of arrests and prosecutions highlight problems of weak enforcement and a lack of coordination between law enforcement agencies, the researchers said.
- Three-quarters of the shipments originated from African countries, they found, with numerous large-scale seizures indicating transnational organized crime.
- With pandemic-related restrictions easing, the worry is that the cross-border wildlife trade will come roaring back even as Vietnam struggles to follow up on investigations into past and current seizures.
In a warming world, deforestation turns the heat deadly, Borneo study finds
- New research identifies how rising localized temperatures driven by deforestation and global warming are increasing heat-related deaths and creating unsafe working conditions in Indonesia.
- In the Bornean district of Berau, 4,375 square kilometers (1,689 square miles) of forest were cleared between 2002 and 2018, contributing to a 0.95°C (1.71°F) increase in mean daily temperature across the district, according to the study.
- It concluded climate change temperature increases in the region caused an 8% rise in mortality rates in 2018, or more than 100 deaths annually, and an additional almost 20 minutes per day of unsafe work time.
- Based on the 2018 data, a projected 2°C (3.6°F) global temperature increase in deforested areas could result in a 20%increase in all-cause mortality — an additional 236-282 deaths per year — and almost five unsafe work hours per day.
Indonesia slashes 2021 mangrove restoration target, vows to make up in 2022
- Indonesia has scaled back its target for mangrove restoration this year, but says its longer-term goal of rehabilitating 630,000 hectares (1.55 million acres) by 2024 remains unchanged.
- It blames “technical hurdles,” including the diversion of funding for the COVID-19 pandemic response, for its decision to revise its 20201 target from 83,000 hectares (205,000 acres) to 33,000 hectares (81,500 acres).
- The country is home to more than a quarter of the world’s mangroves, an ecosystem that buffers coastal communities against storm surges and sea-level rise, stores four times as much carbon as other tropical forests, and serves as a key habitat for a wealth of marine species.
- Indonesia has lost much of its mangroves to shrimp farms and logging, which have also undone previous efforts at mangrove rehabilitation.
‘To change policies, insert yourself in them’: Q&A with biologist Liliana Dávalos
- Colombian biologist Liliana Dávalos has combined conservation research with evolutionary ecology from her laboratory at Stony Brook University.
- Dávalos was one of the first scientists to warn, in 2001, about the environmental risks that an eventual end to the civil war in Colombia would have — a scenario that is now playing out as Colombia’s forests are being opened up for commercial activity.
- Bats are another of Dávalos’s subjects of study: In addition to deciphering their genome to understand their evolution in space and time, more recently Dávalos has studied the relationship of these flying mammals with pathogens such as coronaviruses.
- In an interview with Mongabay, Dávalos, who is openly gay, also talks about attitudes in academia toward women and lesbians, and sends a message to young researchers not to be blinded by the awareness of obstacles.
Indigenous guides warn of repercussions if we don’t fix our relationship with nature
- The Mamos, spiritual guides of the Arhuaco and Kogi peoples in Colombia, have been warning the world about climate change and “unknown diseases” caused by environmental destruction for decades.
- Their homeland, the Sierra Nevada de Santa Marta, is the highest coastal massif in the world and is suffering irreversible damage, including the loss of its glaciers and the decline of its rivers due to climate change and extractive mega projects.
- According to the Mamos, COVID-19 would be only the first of four emerging unknown diseases if humans do not change their abusive relationship with the environment.
COVID could wreak havoc on gorillas, but they social distance better than we do
- A new study models the potential impacts of a COVID-19 outbreak in mountain gorillas using 50 years of population data collected in Rwanda’s Volcanoes National Park with epidemiological variables gathered on COVID-19 infection in humans.
- In most of the scenarios modeled, gorilla populations were found to decline sharply within 50 years of an outbreak.
- Questions remain as to whether the human epidemiological variables used in the analysis are a good fit for gorillas, which spend all of their time outdoors and interact with non-family members far less frequently than humans do.
‘The images are confronting’: Q&A with animal photojournalist Jo-Anne McArthur
- Hidden: Animals in the Anthropocene, published in December 2020, is a photojournalism book that documents the lives and deaths of animals in a human-dominated world.
- The “hidden” animals of the title are those that we humans use for food, fashion, research and cultural purposes.
- The book showcases the work of more than 40 photographers, including co-editor Jo-Anne McArthur, working in the burgeoning field of animal photojournalism.
- Mongabay interviewed McArthur about the creation of the book, the importance of engaging with images of animal suffering, the intersection between animal advocacy and environmentalism, and the growth of animal photojournalism.
Supporting more holistic approaches to conservation: an interview with Kai Carter
- For at least the past 20 years, there has been regular talk about the need to break down silos in conservation. But in practice, the conservation sector as a whole has been slow to bring the necessary voices and expertise into the conversation. That hesitancy, or inertia, can mean missed opportunities to connect conservation with other positive outcomes, from health to livelihoods.
- Kai Carter understands this well: As a program officer at the Packard Foundation’s Agriculture, Livelihoods, and Conservation (ALC) strategy, her work focuses on supporting organizations that work at the intersection of local communities, rights, health, and the environment.
- “Local agriculture, economic development, and conservation are interwoven in people’s lives; they don’t view them as separate,” Carter told Mongabay. “We’ve been exploring how our grantmaking can be more effective by approaching environmental sustainability, livelihoods, community resilience, and health holistically and with the intention of centering the needs and aspirations of smallholder farming communities.”
- Carter spoke about the Packard Foundation’s ALC strategy, equity and inclusion in conservation, and a range of other issues during a recent conversation with Mongabay founder Rhett A. Butler.
In harm’s way: Our actions put people and wildlife at risk of disease
- While global attention is currently focused on COVID-19 and other zoonotic diseases that jump from animals to humans, diseases that breach the species barrier also pass from people and domestic animals to wild species.
- Human alteration of the planet — the felling of forests, the legal and illegal wildlife trade, climate change, and other disruptions — is driving escalating unnatural interactions between species, allowing diseases to mutate and infect new hosts.
- Infectious disease poses a serious threat to tigers, chimpanzees, Ethiopian wolves, African wild dogs and a host of other threatened species. Viral diseases spread by humans, livestock and other domestic animals could serve as the knockout punch to endangered species already teetering on the edge of extinction.
- There’s growing support for a One Health strategy, which recognizes that human health, animal health and the health of the planet are inextricably linked — that protecting the planet is crucial to the health of all.
Biosurveillance of markets and legal wildlife trade needed to curb pandemic risk: Experts
- Almost 90% of the 180 recognized RNA viruses that can harm humans are zoonotic in origin. But disease biosurveillance of the world’s wildlife markets and legal trade is largely absent, putting humanity at significant risk.
- The world needs a decentralized disease biosurveillance system, experts say, that would allow public health professionals and wildlife scientists in remote areas to test for pathogens year-round, at source, with modern mobile technologies in order to help facilitate a rapid response to emerging zoonotic disease outbreaks.
- Though conservation advocates have long argued for an end to the illegal wildlife trade (which does pose zoonotic disease risk), but the legal trade poses a much greater threat to human health, say experts.
- Governments around the world are calling for the World Health Organization to create a pandemic treaty. Wildlife groups are pushing for such an agreement to include greater at-source protections to prevent zoonotic spillover.
For some Indigenous, COVID presents possibility of cultural extinction, says Myrna Cunningham
- COVID-19 has devastated communities around the world, but for some Indigenous groups, the pandemic posed an existential threat.
- Few people are better placed to speak to the impact COVID is having on Indigenous communities than Myrna Cunningham, a Miskitu physician from the Wangki river region of Nicaragua who has spent 50 years advocating for the rights of women and Indigenous peoples at local, regional, national, and international levels.
- Cunningham’s many achievements and accolades include: First Miskito doctor in Nicaragua; first woman governor of the Waspam autonomous region; Chairperson of the PAWANKA Fund; President of the Fund for the Development of Indigenous Peoples of Latin America and the Caribbean (FILAC); Advisor to the President of the UN General Assembly during the World Conference of Indigenous Peoples; member of the Board of Directors of the Global Fund for Women; Deputy of the Autonomous Region of the North Atlantic Coast in Nicaragua’s National Assembly; president of the Association for Women’s Rights in Development; and the first Honoris Causa Doctorate granted by the National Autonomous University of Mexico Universidad Nacional Autónoma de México to an indigenous woman, among others.
- Cunningham spoke about a range of issues in a recent interview with Mongabay founder Rhett A. Butler.
Two threatened whale groups had a mini baby boom, but not because of lockdown
- Two rare whale groups — southern resident killer whales in the Pacific Northwest, and North Atlantic right whales — have had mini baby booms since the start of the pandemic, raising hopes about their survival prospects.
- But experts say a reduction in human activity during this period isn’t the cause, and that the underlying threats pushing these whales toward extinction still persist.
- North Atlantic right whales are threatened by fishing gear entanglement and ship strikes, while the southern resident killer whales have seen stocks of their favorite prey, the Chinook salmon, decline.
- Experts say that policies to protect the whales, including regulating shipping, closing fisheries and restricting certain types of gear, are not keeping pace with whales’ changing dynamics, and that changes might need to be applied throughout their range.
Indonesia investigates alleged abuse of Sumatran tigers at city zoo
- Indonesian conservation authorities have launched an investigation into alleged abuse of Sumatran tigers at a municipal zoo in North Sumatra province.
- The zoo’s tigers appear emaciated, with their bones protruding, raising concerns that they’re being underfed.
- The zoo management has denied the allegation, saying one of its tigers was ill while the others were healthy and properly fed.
- Zoos in Indonesia are notorious for their negligence, mismanagement and corruption, with animals dying of malnutrition or ill treatment, or sold off into the illegal wildlife trade.
When North America locked down, birds filled the gap left by people
- Of the 82 bird species considered in an analysis, the distribution of 66 changed during pandemic-related shutdowns, and most of them grew in abundance in and around human settlements.
- The researchers gathered more than 4 million records from eBird, a community science program that relies on contributions from volunteers, both amateur and specialist birders.
- The study in Science Advances captured how sensitive birds are to human activities and highlighted how small adjustments could make areas used by humans welcoming to other species.
Black-footed ferrets riding out COVID-19 with a vaccine and a lot of TLC
- Black-footed ferrets were nearly wiped out by plague in the 1980s, and were only saved by a last-ditch effort to pull the 18 remaining individuals into a captive-breeding program.
- The wild population now numbers about 300 individuals, but the species remains reliant on captive breeding and sensitive to disease outbreaks — a combination that proved especially nerve-wracking during the COVID-19 pandemic.
- Luckily, black-footed ferret keepers are no stranger to disease-mitigating measures, and were able to successfully breed ferrets with the help of rigorous sanitation measures, dedicated staff, and even a vaccine.
- To date, no black-footed ferrets have tested positive for COVID-19, and after a 50% drop in the number of kits born last year, the program is back to producing its usual number of kits.
Congo’s bongos are in danger, and curbs on trophy hunting could save them
- Unsustainable hunting quotas could drive a rare African antelope to extinction in one corner of the Republic of Congo, a study by the NGO Wildlife Conservation Society has found.
- There are fewer than 30,000 bongos left today, inhabiting wooded expanses south of the Sahara in Africa, including in the Republic of Congo, which allows commercial hunting of these prized ungulates.
- The country’s hunting allotment of 15 adult males a year, at the time of the study, could lead to their disappearance within 25 years from the Bonio hunting concession, researchers say.
- Apart from trophy hunting, disease outbreaks, habitat loss and unregulated hunting also menace the eastern bongos of Congo.
Domestic bushmeat consumption an “urgent” threat to migratory mammals, U.N. says
- A recent U.N. report has found that many migratory mammals are in grave danger of being hunted for meat for domestic consumption, which in many cases poses a greater risk to population numbers than international trade.
- There is also strong evidence that wild meat taking and consumption is linked to zoonotic diseases.
- The authors say that while wild meat consumption cannot be eliminated because it is an indispensable source of nutrition and income for rural communities, they call for improved national regulations and international cooperation to safeguard threatened species.
Saving sea turtles in the ‘Anthropause’: Successes and challenges on the beach
- The COVID-19 pandemic has posed tough challenges for sea turtle conservation projects across the planet.
- Conservationists describe how economic issues have put turtles and themselves at risk from poachers, while travel restrictions have crippled operations in Costa Rica and Malaysia.
- The lull in human seashore activities also revealed that tourism pressure affects nesting turtle behavior in the Mediterranean, a study shows.
- In Lebanon, raising awareness has been key to turtle conservation successes despite the country’s economic collapse, conservationists said.
Fashions to die for: The fur trade’s role in spreading zoonotic disease
- It has long been known that zoonotic diseases, which originate in animals and can jump to humans and back again, have been a prime source and vector for pandemics, with COVID-19 the most recent example. What is less known is the role the global fur-for-fashion industry plays in the spread of zoonotic disease.
- In 2020, COVID-19 spread to minks on EU fur-to-fashion farms; the virus also spread from the animals to a farm worker. Denmark ordered the culling of 17 million farm-raised minks. Mink farms in 10 countries have since been hit by outbreaks, including the U.S., Canada, France, Greece, Italy, Latvia, Lithuania, Poland, Spain and Sweden.
- China is the largest producer and consumer of fur for fashion, with the U.S. and EU both major players as well. In China, government support, producer lobbying, weak regulation and popularity with Chinese consumers has kept that nation’s fur market strong. It is very well supplied by Chinese farms and EU fur farm joint ventures.
- The fashion trend today is not for full-length fur coats, but for fur trim on sports coats, caps, shoes and accessories. Animals killed for their fur include minks, sables, rabbits, chinchillas, foxes and raccoon dogs. All have the potential to serve as zoonotic disease sources and spreaders. Globally, an estimated 95% of fur comes from farms.
Study fails to find link between increased deforestation and COVID lockdowns
- Macroeconomic analysis suggests deforestation trends have not changed significantly in the past year as a direct result of the COVID-19 pandemic.
- Lockdowns and layoffs, and the unprecedented stimulus spending in response to them, were expected to lead to a spike in deforestation, but this wasn’t the case, the analysis shows.
- Still, campaign groups say there are signs of unsustainable expansion plans among the forest products sector in Asia.
- Conservationists are calling on world leaders to use the climate change conference later this year to make recovery programs more sustainable.
Borneo’s bearded pigs and traditional hunters adapted to oil palms. Then came swine fever
- Oil palm expansion and urbanization have altered the traditional hunting of bearded pigs by the Indigenous Kadazandusun-Murut (KDM) community in Sabah, Malaysia, a new study has found.
- Researchers interviewed 38 hunters on changes in pig behavior and hunting practices before the African swine fever (ASF) epidemic hit Sabah in 2021.
- They found that even though pig hunting patterns have changed dramatically, the activity remains a cornerstone of KDM communal culture for food, sport, gift-giving, festivals and celebrations.
- As ASF devastates wild pig populations, the researchers’ findings highlight a need for long-term hunting management that conserves both the bearded pig and Indigenous cultural traditions.
Plant-based face masks? This young Philippine inventor has you covered
- A Filipino high school student has developed a plant-based wax that has shown potential in increasing the life span and effectiveness of reusable face masks.
- Kiara Raye Cartojano, 18, says she hopes the project can reduce the number of disposable face masks discarded in her city, estimated at more than 480,000 per day since the start of the COVID-19 pandemic.
- The wax is made from the leaves of the taro plant, a widespread plant with the potential to displace native vegetation and threaten agricultural crops.
Conservation after coronavirus: We need to diversify and innovate (commentary)
- Protected areas, the ecotourism industry, and many conservation initiatives and communities, which depend on international tourism, took a financial hit as COVID-19 lockdowns started. As poverty swelled in these regions, there’s been an increase in poaching in Africa’s protected areas, including Zambia’s Kafue National Park.
- Long before the emergence of COVID-19, the conservation community has suffered from a chronic dearth of resources; with the pandemic, protected areas and related communities experienced a sharp retraction in investment.
- With examples from across the world, philanthropist Jon Ayers and Panthera CEO Frederic Launay call for diversified and innovative steps to increase funding and support for conservation communities.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
There is no climate solution without China and America, says Li Shuo
- China and the United States account for nearly half the world’s carbon dioxide emissions from energy, while the two countries’ resource consumption is among the biggest threats to global biodiversity. These issues make China and the U.S. major targets for environmental activists like Greenpeace.
- Despite the difference in political systems between China and the U.S., Li Shuo, Senior Climate and Energy Policy Officer at Greenpeace China, says the approach Greenpeace uses in China, like other places, is based on building trust.
- Li Shuo says the countries share another similarity: They are lagging behind on their climate commitments: “There is no climate solution without the G2 rolling towards the same direction,” Li Shuo told Mongabay. “The U.S. can do all it can to reduce emissions. It won’t solve the problem as long as China doesn’t comply, and vice versa.”
- Beyond climate, China and the U.S. have another near-term opportunity to collaborate: averting the global extinction crisis via strong action and commitment at the upcoming U.N. Conventional on Biological Diversity (CBD).
Studies debunk ‘nature is healing’ narrative from 2020 lockdowns
- Several new studies have tried to tally up the costs and benefits to the environment as a result of lockdowns around the world last year in response to the COVID-19 pandemic.
- One study showed that emissions of indirect greenhouse gases like CO and NO2 decreased significantly, but one of its authors says this likely won’t have much of an impact over the long term.
- Another study debunks the media hype behind the “animals are reclaiming the cities” trend last year, attributing the increased sightings to the fact that people forced to stay at home finally had time to start noticing the wildlife around them.
- In India, researchers concluded there were more negatives than positives for the environment, including a surge in the use of plastic packaging and PPE, as people shopped online and masked up.
Captive breeding of Sumatran rhinos: Where the program stands today
- In a series of video interviews, Mongabay speaks with Sumatran rhino experts to get up-to-date information on efforts to breed the species in captivity.
- The interviews focus on three locations that host the vast majority of Sumatran rhinos, whose entire population is believed to number no more than 80.
- The interviews reveal fears stemming from the dire state of the species, as well as optimism that officials and conservationists are finally working with united purpose to keep the species from sliding into extinction.
L.A.-sized tract of primary forest went up in flames in DRC province in 2020
- In 2020, more than 1,500 square kilometers (580 square miles) of old-growth forest burned in Sankuru province, including extensive tracts in a nature reserve.
- Overall, the DRC recorded its second-biggest decline in primary forest cover last year, according to data from Global Forest Watch (GFW), a platform developed by World Resources Institute.
- Forests in the country face increasing pressure from a constellation of factors: a growing population, climatic shifts like shorter rainy seasons, and, more recently, COVID-19-linked turmoil.
- In the past two years alone, more than 1,000 km2 (390 mi2) of land in Sankuru Nature Reserve was set alight.
Illegal mining in Colombia’s Amazon threatens Indigenous communities
- In June 2021, Indigenous communities observed boats carrying out illegal gold mining in the Caquetá River in the Colombian Amazon.
- Satellite images showed as many as 19 boats that month on the Puré River, one of the Caquetá’s tributaries.
- Research shows mercury contamination from gold mining has contaminated Indigenous communities in the Caquetá River Basin.
- Researchers and Indigenous advocates warn the influx of miners into the remote Colombian Amazon may compromise the health and well-being of uncontacted peoples who depend on isolation for their way of life.
Not just for humans — scientists turn to vaccines to save endangered species
- Vaccines developed for animals, including rabies or swine fever shots, have historically been aimed at protecting humans rather than the animals themselves.
- Scientists are now increasingly looking at animal vaccines as a means of saving wild populations of threatened species.
- As with vaccines for humans, development cycles can take a decade or more, and the challenge of administering doses is far more complex.
- But some initiatives have shown promise in protecting wildlife from infectious diseases that could otherwise lead to entire species being decimated.
In Brazil’s Acre, smoke from fires threatens health, could worsen COVID-19
- Fires are gaining momentum in Acre, a state in southwesten Brazil 80% covered in old-growth Amazon rainforest, where a historic drought and high levels of deforestation have experts worried that this will be a bad year for fires
- Wildfires generate small particulate matter which, when inhaled, can travel into the lungs, bloodstream, and vital organs, causing serious damage, akin to cigarette smoke.
- Data from Acre’s air-quality monitoring network, the largest in the Amazon, show that during the peak burning seasons in 2019 and 2020, the rates of particulate matter hovered well above the level recognized by the World Health Organization as clean and safe for breathing
- Wildfire smoke has been linked to higher COVID-19 mortality rates, threatening to compound what is already one of the worst burdens of coronavirus infections and deaths in the world. At particular risk are Indigenous populations, who suffer mortality rates 1.5 times the average in Brazil.
On World Elephant Day (and every day) humans should stay away from wildlife (commentary)
- Though we appreciate wild animals like elephants on World Elephant Day (August 12) and every day, travelers and the tourism industry need to stop seeking and promoting hands-on experiences with wild animals, a new op-ed by an elephant researcher argues.
- When humans insist upon touching, feeding, and taking photos with wild animals like elephants, it changes their behavior in ways that can be dangerous, as in the cases of begging for food and habituation.
- The COVID era underscores this: humans have become vectors for the disease, and both wild and captive animals have caught it, so we should exercise caution and limit interactions especially with endangered species.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Black Death aside, we know surprisingly little about rodents and disease
- Rodents make up 40% of all mammal species on the planet, and an estimated 10.7% of them are known hosts of zoonotic diseases, such as cat scratch disease, bartonella, hantavirus, Lyme disease, leishmaniasis, leptospirosis, and the plague.
- A recent letter in the journal Conservation Biology calls for more attention and funding to be directed toward studying small rodents, “the wildlife species most likely to be abundant, come into contact with humans, and be potential reservoirs in future zoonotic outbreaks.”
- Controlling and mitigating the risk of zoonotic diseases through rodent control is another area that lacks research, with the current approach of killing and poisoning rodents in urban areas actually posing the risk of causing more disease.
- Experts call for evidence-based, whole-system approaches to control rodents and champion the One Health approach to address zoonotic disease, acknowledging that human, environmental, and animal health are all interconnected.
