Climate change drives uneven shifts in tree diversity across Amazon and Andes
- A team of researchers looked at changes in tree richness across the lowland and montane forests of the Andes and Amazon over the last four decades.
- While their results didn’t show an overall shift in any one direction, they found that tree richness changed significantly across the six subregions: forests in the central Andes, Guyana Shield and central-eastern Amazon have been losing species, while the northern Andes and western Amazon showed increased tree richness.
- Changes in the seasonality of precipitation, total rainfall, temperature, as well as the degree of forest fragmentation are key drivers for tree richness: forests that warmed more since 1971 lost species faster than those moderately warming; but regionally, precipitation plays a bigger role than temperature in richness changes.
- Forests with a higher number of trees and landscape integrity gain species, so limiting deforestation across the Andes–Amazon ecosystems can protect tree richness, in particular the northern Andes, which could serve as a key refuge for species that can no longer survive the warming Amazon.

Out of captivity, into conflict: slow lorises struggle to survive after release
- A study in Bangladesh found that seven of nine rescued Bengal slow lorises died within six months of release, showing that rewilding trafficked animals can become a “death trap” if habitat and social conditions aren’t right.
- Most of the dead lorises bore venomous bite wounds from their wild counterparts, indicating that releasing highly territorial animals into already occupied forests can trigger lethal fights.
- The two that survived established larger home ranges, while those kept longer in captivity fared worse, underscoring the need for careful site selection, population surveys, and evidence-based release protocols.
- Experts say that rescue and release only address the symptoms of illegal wildlife trafficking, and that curbing poaching and habitat loss is essential to prevent further harm to both individuals and wild populations.

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.

In Thailand, old camera-trap photos shed new light on Asian tapirs
- Archived camera-trap data from southern Thailand’s Khlong Saeng–Khao Sok Forest Complex identified at least 43 individual Asian tapirs, suggesting the area may be a key refuge for the endangered species.
- Researchers used “bycatch” images from camera traps originally set to photograph bears to estimate tapir density at 6-10 individuals per 100 square kilometers, showing existing data can help monitor elusive species.
- Modeling suggests the forest complex could hold up to 436 mature tapirs, far higher than previous estimates for Thailand and Myanmar combined, though researchers warn the figure may overestimate actual numbers.
- Despite the promising findings, Asian tapirs face ongoing threats from habitat loss and snaring, and experts say protecting intact forest strongholds is vital for the species’ survival.

It’s electric: Scientists develop cheap way to keep sharks off fishing hooks
- Unintentional catch is a major reason that more than a hundred shark species are threatened with extinction.
- A new study found that creating a small electric field around fishing hooks using zinc and graphite is enough to keep many sharks away.
- Researchers have for decades tried to take advantage of sharks’ electrosensitivity to develop devices to keep them off fishing hooks. The authors of the new study chose zinc and graphite because they’re nonmagnetic, cheap and readily available materials.
- The lead author and two former students are pursuing commercial applications for the new method.

New study assesses geoengineering marine ecosystem risks, knowledge gaps
- A new review study examines the current research regarding the risks that various geoengineering approaches pose to marine ecosystems.
- The study looked particularly at a range of marine carbon dioxide removal (mCDR) methods, along with solar radiation modification (SRM) technologies, and found that some approaches carry fewer risks than others.
- Electrochemical ocean alkalinity enhancement and anoxic storage of terrestrial biomass in the deep ocean (utilizing crop waste, for example) carry fewer risks to marine ecosystems than some carbon dioxide removal methods, such as those that would add nutrients to seawater to promote major plankton growth.
- However, better models, increased field testing, and better geoengineering regulatory oversight are needed to fully assess potential geoengineering marine ecosystem impacts, especially if commercialization proceeds. Public fears over field testing also need to be allayed.

Study refutes claim that Indonesia’s legal turtle trade supports livelihoods
- Tens of thousands of freshwater turtles and tortoises are legally harvested each year in Indonesia for their meat and exported primarily to China, while many species teeter on the brink of extinction.
- Although this turtle trade is thought to provide livelihoods for harvesters, a study finds that with current market prices, it only supports a few hundred people nationwide with a barely sustainable minimum wage income.
- A big proportion of the trade must be illegal to keep it profitable, researchers say. They question whether it should be permitted at all, given that many targeted species are threatened with extinction.
- To prevent illegal trade, conservationists urge Indonesian authorities to enforce harvest quotas, ban the trade of threatened species and provide alternative livelihoods for harvesters to save the country’s chelonians.

Mapping underground fungal networks: Interview with SPUN’s Toby Kiers
- Mycorrhizal fungi are found in every soil system on Earth, and have symbiotic relationships with the plants whose roots they live on.
- They receive carbon dioxide from plants in exchange for nutrients, making them major carbon repositories and an important tool for carbon sequestration.
- The Society for the Protection of Underground Networks (SPUN) is deploying a wide range of technologies, from remote sensing to imaging robots, to map these crucial underground networks.
- “We think of these networks as one of Earth’s circulatory systems, but people are not paying attention,” SPUN co-founder Toby Kiers tells Mongabay in an interview.

Rodent burrows offer unusual sanctuary to Africa’s smallest wildcat
- New research shows female black-footed cats rely heavily on abandoned springhare burrows to shelter themselves and raise their kittens, using a constantly shifting network of underground dens to survive Southern Africa’s harsh, semiarid landscape.
- Mothers rotate frequently among multiple dens — sometimes almost daily once kittens begin to move — a strategy likely aimed at avoiding predators and minimizing scent trails.
- Despite weighing as little as 1 kilogram (2.2 pounds), black-footed cats are among the most active and efficient hunters of any feline, ranging over large territories at night and retreating underground by day.
- With low reproductive rates, disease pressure and a population of around 10,000, the species’ survival depends on protecting both springhares and the working landscapes of livestock farms, where burrow loss, overgrazing and predator control can indirectly threaten the cats.

Risk-taking comes earlier in chimpanzees than in humans, study finds
- A study found that chimpanzees tend to take more physical risks as infants and young animals rather than as adolescents, like humans.
- The researchers hypothesize that the level of care humans provide may cut down on the risks young children might otherwise take.
- The team tracked how often 119 chimps dropped or leaped through the forests without holding onto any branches at Uganda’s Ngogo Chimpanzee Project, and analyzed the results according to the animals’ ages.
- Infant and young chimpanzees were more likely to launch themselves through the trees than adolescents or adults, despite the risk of injury.

Seagrass restoration in Malaysia finds multi-species approach boosts recovery
- Seagrass restoration is increasingly recognized as crucial for addressing the twin crises of biodiversity loss and climate change.
- However, much remains unknown about the most effective techniques, especially in tropical ecosystems where long-term projects struggle for funding.
- A decade-long seagrass recovery program in Peninsular Malaysia has achieved high survival rates at a site heavily impacted by coastal development, raising hopes that degraded meadows can be revitalized.
- The study also identified several factors that can increase success, including: knowledge of the biology of local seagrass species, adapting methods to suit local environmental and physical conditions, and properly addressing the original drivers of decline.

Conservation programs must embrace causal evidence when evaluating impact (commentary)
- A couple of seminal studies published almost 20 years ago found that conservationists needed to start examining whether their actions were actually causing the desired effects.
- Assessing conservation projects through a causal lens takes more effort but can ultimately be a big piece of the puzzle that helps practitioners identify cause-and-effect relationships between various factors.
- “What’s needed now is making causal evaluation standard practice rather than the exception. With biodiversity in crisis, we can’t afford to keep guessing whether our actions work,” a new op-ed argues.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

African wild dogs break the carnivore rule in Botswana
For the first time, “hyper-carnivorous” African wild dogs have been recorded eating fruit, a behavior so far documented only in a small part of Botswana’s wildlife-rich Okavango Delta. The wild dogs were seen picking up jackalberries, the fruit of the African ebony tree (Diospyros mespiliformis), with their teeth and swallowing them almost whole. Jackalberries […]
‘Blew us away’: Researchers find nitrogen boost spurs faster tropical forest growth
- A new study in Panama finds that nitrogen availability limits forest growth in the early stages of regeneration.
- Nitrogen addition to newly cleared land and 10-year-old forests substantially boosted regeneration, though adding nutrients to older forests did not have the same effect
- The study also found that phosphorus availability did not limit forest growth at any stage of forest maturity.
- The researchers recommend ensuring nitrogen-fixing species are included during reforestation.

Cameroon cookstove project looks to slow forest loss
- The Center for International Forestry Research (CIFOR) hopes new cookstoves that require less wood than traditional varieties will slow forest loss in Cameroon.
- Mongabay visited one of the villages where CIFOR’s project is taking place to talk to people who are involved in it.
- Long-term success rates for similar projects in Africa have often been low.
- CIFOR wants to break that trend by encouraging people to adopt the new cookstoves and keep using them.

More than 87m people impacted by climate-related disasters in 2025
In 2025, more than 200 climate-related disasters affected more than 87.8 million people worldwide, according to preliminary figures from the International Disaster Database analyzed by Mongabay. The disasters include flash floods, landslides, severe storms, wildfires and droughts. Drought and food insecurity impacted the largest number of people. In Syria, which faced its worst drought in […]
Study ties same-sex behavior in primates to ecological and social pressures
- A recent study into same-sex behavior in primates finds that social organization and ecological factors, including climatic conditions, influence this behavior.
- In gorilla groups, same-sex relations can help strengthen social bonds, study lead author Chloë Coxshall told Mongabay, reducing competition and facilitating access to mates and resources.
- Gorilla groups typically consist of a dominant adult male, several adult females, and their offspring. If the dominant male has the exclusive right to mate with all females of the same group, sometimes this polygamy pushes the females to leave this family to look for other females with whom they develop intimate relationships, Malagasy primatologist Jonah Henri Ratsimbazafy said.
- Same-sex behavior doesn’t appear to have the same place in the lives of different primate species or even at various times for the same population, the study suggests. So species-specific research is needed, according to the study authors.

Coast-to-coast coral assessment reveals Thailand’s reefs losing complexity
- Marine scientists have documented Thailand’s coral reefs in unprecedented detail, providing a crucial baseline against which reef managers can measure future change.
- The surveys indicate that, as in other parts of the world, Thailand’s reefs are losing structural complexity, becoming dominated by simpler boulder-forming corals, while staghorn and branching species die out.
- Experts say the new baseline can help steer future strategies to prepare for future bleaching events through reef restoration and assisted reproduction.
- The surveys were conducted just before the full effects of the 2024 global bleaching event were felt in Thai waters, which will have inevitably taken an as-yet-unquantified toll on the region’s reefs.

Earth Rover Program seeks to track the world’s soil health
- Leveraging tools from seismology — the study of earthquakes and the inside of our planet — the Earth Rover Program aims to provide critical data on the health of soil.
- Humans, and terrestrial life in general, depend on the soil for nourishment.
- Yet, in many parts of the world, soils are degraded, worn out and eroding away.
- The recently founded program involves the development of inexpensive technology that farmers and scientists alike can use to better understand soil health and what can be done to improve it.

Too many African plants fall into the IUCN’s ‘not evaluated’ trap (commentary)
- Of the approximately 350,000 vascular plant species in the world, only about 18% have been assessed by the IUCN Red List, and the situation is starker still if one looks at just tropical African species.
- Further, IUCN’s “not evaluated” category simply means a species has not yet been assessed against Red List criteria, and in practice, African conservationists often meet a more confusing reality: Many species are not on the global Red List at all but are still informally talked about as if they are NE.
- “Here’s a constructive way forward via “Red List + Reality” decision rules…A stronger system could combine global assessments with local intelligence,” a new commentary suggests.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

How many insects does California have? We’re getting closer to an answer
California’s insects are as outsized as the state itself. Between its redwood forests and desert basins may live 60,000, perhaps even 100,000 species — though no one truly knows. That uncertainty drives the California Insect Barcode Initiative, an audacious attempt to document every insect in the state through DNA sequencing. Leading the effort is Austin […]
Hidden heroes: Australian tree bark microbes consume greenhouse & toxic gases
- A new study carried out in Australia finds that the bark of common tree species holds diverse microbial communities, with trillions of microbes living on every tree.
- The research determined that many of these microbial species specialize in metabolizing methane, hydrogen, carbon monoxide and volatile organic compounds (VOCs).
- Methane is a powerful greenhouse gas, while hydrogen and carbon monoxide are considered indirect greenhouse gases. Carbon monoxide and VOCs are also both hazardous to human health.
- The study found that tree bark microbes play a significant, previously unknown role in atmospheric gas cycling, potentially boosting estimations of the climate benefits offered by global forests. Learning which tree species boast the best microbes for curbing climate change and pollution could better inform reforestation strategies.

Nitrogen may turbocharge regrowth in young tropical forest trees
New research finds that tropical forests can grow significantly faster and sequester more climate-warming carbon dioxide when additional nitrogen is available in the soil. “With this information we can prioritise management and conservation practices to maximise forest regrowth,” Kelly Anderson, a research scientist at Missouri Botanical Garden in the U.S., told Mongabay by email. Anderson […]
A novel sanctuary in Antarctica is preserving ice samples from rapidly melting glaciers
ROME (AP) — Scientists in Antarctica on Wednesday inaugurated the first global repository of mountain ice cores, preserving the history of the Earth’s atmosphere in a frozen vault for future generations to study as global warming melts glaciers around the world. An ice core is something of an atmospheric time capsule, containing information about the Earth’s past […]
Greenland sharks retain functional vision despite extreme longevity
Greenland sharks are the longest-living vertebrate known to science, topping out at more than 400 years old, and scientists have largely believed they were nearly blind. But new research suggests they actually can see, and, remarkably, maintain their vision for more than a century. Greenland sharks (Somniosus microcephalus) mostly live in the cold waters of […]
Study tracks fishing boats to see how heat waves affect fish distribution
- A new study suggests an early way to detect ecological shifts during marine heat waves: Use fishing vessel tracking data.
- The study found that tracking data could provide early detection of extreme northward and inshore shifts in albacore tuna and Pacific bluefin tuna distribution in response to heat waves and showed when such shifts weren’t happening despite high sea surface temperatures.
- The authors position fishers as “apex predators” and build on research that finds that predators are good ecosystem sentinels.

Myanmar’s botanical data gaps risk its unique flora, collaborations could help, study says
- Home to snowcapped mountains, drought-prone savannas and tropical rainforests, Myanmar hosts tremendous botanical diversity among its richly varied habitats.
- There are 864 known plant species that are found only in the conflict-torn country, yet critical knowledge gaps remain.
- Researchers recently compiled what is known about Myanmar’s flora, identifying key research gaps and priority areas where conservation efforts for plants are most urgently needed.
- They urge collaborative and systematic action to fill in data gaps and protect floristically diverse areas and avoid irreversible species losses.

Methane chasers: Hunting a climate-changing gas seeping from Earth’s seafloor
- Methane is a potent greenhouse gas that can pack more than 25 times the global warming punch of carbon dioxide, and atmospheric methane emissions have been growing significantly since 2007. So it’s vital that humanity knows how and where methane emissions are coming from, including the world’s oceans.
- Scientists first raised the alarm over methane releases from shallow waters in the Arctic Ocean between 2008 and 2010. But recently, they were surprised to discover new releases in shallow waters off Antarctica. Researchers continue spotting additional seafloor seeps there and elsewhere, as methane bubbles escape seafloor sediments.
- In shallow waters, methane bubbles that break the ocean’s surface add greenhouse gases to the atmosphere, but to learn how much climate risk these bubbles pose, scientists first have to find them. The hunt for methane bubbles requires everything from underwater microphones and sonar maps to scuba divers and submersibles.
- Methane seeps are more than a potential climate change threat. They also form the basis of unique chemosynthetic ecosystems that influence the deep sea and may hold clues about the origin of life. Finding and studying those seeps present fascinating challenges, requiring ingenuity and creative thinking by researchers.

5 unexpected animal behaviors we learned about in 2025
Every year, researchers and people out in nature capture some aspect of animal behavior that’s unusual or unexpected in some way, changing how we understand the natural world. Here are five such examples that Mongabay reported on in 2025: Massive fish aggregation seen climbing waterfalls in Brazil For the first time, scientists observed a “massive […]
How are California’s birds faring amid ever more frequent wildfires?
- Long-term research in California shows that many bird populations increase after wildfires and can remain more abundant in burned areas for decades, especially following moderate fires.
- Although some bird species are adapted to fire and benefit from low to moderately severe blazes, megafires in California are becoming more frequent.
- Megafires, scientists say, are unlikely to benefit most bird species and harm those that depend on old-growth forests.
- Wildfire smoke poses a serious threat to birds’ health, with evidence linking heavy exposure to particulate matter in smoke to reduced activity, weight loss and, possibly, increased mortality.

Ditches on peatland oil palm plantations are an overlooked source of methane: Study
- Ditches that drain peatlands for agriculture are significant but often-overlooked sources of greenhouse gases, including methane, according to a recent study.
- Methane doesn’t last as long as CO2 in the atmosphere, but it is many times more potent in warming the climate.
- The researchers analyzed emissions from ditches on two oil palm plantations in Malaysian Borneo and found that the ditches play an outsize role in the overall carbon emissions from converted peatlands.
- Their findings underscore the need to account for emissions from these ditches to better understand the implications of draining peatlands.

Sri Lanka looks to build disaster-resilient housing after devastating cyclone
- More than 1,200 landslides were recorded in two provinces in Sri Lanka following Cyclone Ditwah in late November, resulting in crisis evacuations to safeguard vulnerable populations.
- Most of the disaster-impacted people continue to live in high-risk regions due to the lack of alternative housing.
- The country’s mandated institution for landslide risk management, the National Building and Research Organisation (NBRO), says it’s working on the first national building code to establish minimum standards for the design, construction and maintenance of hazard-resilient housing.
- Following the significant loss of lives and homes in the recent disaster, the NBRO is also introducing specific types of housing models suitable for flat and sloped terrains.

How ‘Adventure Scientists’ provide pioneering data for conservation
Gregg Treinish didn’t start out as an outdoor enthusiast, but found solace and purpose in nature during his youth. After years of enjoying the outdoors, he was left feeling a need to give something back to the world. He found fulfillment by using his passion for outdoor adventures to gather critical data that researchers need […]
As Cyclone Ditwah battered land, Sri Lanka’s oceans absorbed a silent shock
- Following the tropical Cyclone Ditwah, unusual sea-foam appeared along parts of Sri Lanka’s northern coast, a natural phenomenon caused by storm-driven turbulence and organic compounds released by plankton, not marine pollution, scientists say.
- Extreme rainfall from Ditwah released an extraordinary volume of freshwater into the ocean, and researchers estimate that nearly 10% of Sri Lanka’s average annual rainfall was received in a single day and rapidly drained to sea through the island’s river network.
- Flood-driven sediments and sudden changes in salinity may stress coral reefs and coastal ecosystems, but Sri Lanka lacks systematic sediment monitoring at river mouths, leaving scientists with limited data on downstream impacts.
- The floods also swept plastics, debris and nutrients into coastal waters, potentially intensifying plankton blooms and fish aggregations while increasing the risk of algal blooms, oxygen depletion and long-term marine pollution.

New miniature bright-orange toadlet found in southern Brazil and named after Lula
In a small stretch of the Atlantic Forest in southern Brazil lives a bright-orange species of frog that’s new to science, researchers report in a recent study. The miniature amphibian measures just over a centimeter long, less than half an inch, or the length of an average fingernail. The team has named the toadlet Brachycephalus […]
Tanzania’s tree-climbing hyraxes have adapted to life without trees
Despite their name, tree hyraxes — small, furry, nocturnal African mammals — don’t always live in trees. In Tanzania’s Pare mountains, near the border with Kenya, they’ve adapted to life on steep rocky outcrops as forests disappeared over the centuries, a recent study has found. Eastern tree hyraxes (Dendrohyrax validus) are known to inhabit the […]
How Southern African farmers & elephants can both adapt to coexist
- In Southern Africa, people live alongside elephants, but not always peacefully.
- The growing reports of human-elephant conflict have triggered calls for elephant culls in some countries, like Zimbabwe.
- But conservation groups are working hard to promote coexistence, using technology that can warn farmers about approaching elephants or link farmers to more lucrative markets to offset the cost of living with one of Africa’s most charismatic mammals.
- In all of this, adaptation is the key: Farmers are adapting the way they farm, while elephants are learning to move at night and stick to specific routes through populated areas to avoid conflict.

When abandoned conservation projects are counted as progress, what are we protecting? (commentary)
- An issue that receives little attention from conservationists and funders is the quiet abandonment of conservation projects after their high-profile launches.
- New evidence suggests that over one-third of conservation initiatives are abandoned within a few years of launch; if these eventual failures are not reported, they tend to be assumed to remain active.
- “Conservation must be reframed as a long-term commitment. Until the community confronts the uncomfortable truth that starting new projects holds no value unless existing ones are sustained, billions of dollars will continue to be spent on initiatives that provide the illusion of progress while nature continues its decline,” a new op-ed argues.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

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.

Earth’s freshwater fish face harsh new climate challenges, researchers warn
- Climate change is rapidly altering freshwater ecosystems — raising temperatures, altering flood pulses and oxygen levels — and driving complex, region-specific changes in how fish grow, migrate and survive.
- Long-term U.S. data show sharp declines in cold-water fish as streams and lakes warm, while warm-water species gain only slightly. Some cold-adapted species are now disappearing as deep waters cease being a cold refuge.
- From Africa to the Arctic, impacts are emerging, including stronger lake stratification, declining fisheries and rivers turning orange as thawing permafrost releases toxic metals. Declining freshwater fisheries increasingly put food security at risk, especially affecting diets and health in traditional and Indigenous communities.
- Scientists say management and conservation techniques rooted in past conditions no longer work. New approaches must anticipate shifting baselines as climate change rapidly accelerates.

New study points to private land as key to Atlantic Forest recovery
- A new study shows that restored private lands in Brazil’s Atlantic Forest achieved up to 20% more forest cover than unrestored neighboring private lands.
- With 75% of the Atlantic Forest in private hands and a 6.2-million-hectare (15.3-million-acre) deficit of native vegetation, according to the law, private landowners are key to recovery.
- Over the past decade, forest gains and losses in the Atlantic Forest have essentially stagnated; but last year, half of all deforestation hit mature forests over 40 years old, threatening biodiversity and carbon stocks.

Noisy traffic is making Galápagos’ yellow warblers angry
A recent study found that birds that live closer to roads display more aggression than birds of the same species that live farther away from noisy vehicles, Mongabay’s Spoorthy Raman reported. Researchers looked at the behavioral differences of male Galápagos yellow warblers (Setophaga petechia aureola) on two islands of the Galápagos, an Ecuadorian archipelago in […]
Study finds more ‘laggards’ than ‘leaders’ among high seas fisheries managers
- A new paper suggests that regional fisheries management organizations (RFMOs) haven’t done a very good job setting up systems to conserve fish stocks and broader ecosystems.
- The paper questions RFMOs’ readiness for a coming new era of marine governance, with the high seas treaty set to take effect in January.
- The authors rated 16 RFMOs based on 100 management-related questions, such as “Are there consequences for violations of conservation measures …?” and used the answers to help identify “leaders” and “laggards.” The average rating was 45.5 out of 100.
- They also determined that on average, more than half of RFMOs’ target stocks are overexploited or collapsed, reinforcing previous research.

Africa’s wildlife has lost a third of its ‘ecological power,’ study says
- A recent study quantifies the impact of biodiversity loss on ecological functions by tracking energy flows within them. It found that declines in birds and small mammals have led to a significant erosion of ecological functions in sub-Saharan Africa.
- The study crunched data on nearly 3,000 bird and mammal species found in the region, which performed 23 key ecosystem functions, ranging from pollination to nutrient disposal.
- In the paper, the researchers group animals according to the ecological roles they play. By taking into account species present in an area, their abundance, body sizes, diets, and metabolic rates, they turn the animal’s food consumption into a measure of energy flow.
- The analysis found that the “ecological power” of wild mammals and birds weakened drastically, by about 60%, in areas converted to agricultural land; however, in well-managed protected areas, ecological functions are almost 90% intact.

Corridors, not culls, offer solution to Southern Africa’s growing elephant population
- Elephant populations in Southern Africa are stable or growing, but the space available for them is not.
- Often, elephant populations are constrained, increasing their impact on the environment or surrounding communities, and triggering calls for controversial solutions, like culls or contraception.
- But studies in a region that hosts 50% of Africa’s remaining savanna elephants (Loxodonta africana) show how the animals make use of wildlife corridors to move between protected areas and neighboring countries.
- Encouraging elephants to migrate can help relieve overpopulation in some areas, but any corridor invariably intersects with human communities, making it both vital ecological infrastructure and a social challenge.

Choosing coexistence over conflict: How some California ranchers are adapting to wolves
- California’s expanding gray wolf numbers — a conservation success for an endangered species — have worried ranchers in recent years as wolf-related livestock kills mount.
- Some ranchers are adapting to the changing landscape, using short-term nonlethal deterrents, some of which are funded by a state compensation program.
- A few ranchers are exploring long-term approaches, such as changing their ranching practices and training their cattle to keep them safe from wolves.
- While change is hard, ranchers acknowledge that learning to live with the new predator is the only way forward, and it pays to find ways to do so.

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.

Botswana’s elephant hunting quota threatens to wipe out mature bulls: Report
The reintroduction of elephant trophy hunting in Botswana in 2019, following a five-year moratorium, is likely severely depleting the number of large, older bulls, according to a recent report. This has put the country’s elephant population at risk and induced behavioral changes in the mammals, researchers say. Since 2019, Botswana has permitted roughly 400 elephants […]
Warmer climate triggers pest infestations in Bangladesh, India tea estates
- A warmer climate triggers pest infestations across tropical tea estates in Bangladesh and India.
- Since traditional pesticides fail in pest control, the producers experience significant losses in terms of production as well as earning.
- Experts recommend comprehensive solutions with integrated pest management and improvement of soil health.

Turning adventure into data
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries.

Years of wandering through wilderness had left him restless. “I was spending years in the wilderness, doing long expeditions, and I began to feel selfish for […]
In wake of Cyclone Ditwah, Sri Lanka faces continuing disaster risks
- The devastating Cyclone Ditwah has left a trail of destruction over 25 districts in Sri Lanka and killed 474 people; among the hardest-hit are those inhabiting low-lying coastal areas and the tea growing Central Highlands.
- Increasing vulnerability to extreme weather events among littoral populations is exacerbated by high population density, experts say.
- More than one-third of the Sri Lankan population, or more than 4.5 million people, live along the coastline and population density is projected to reach 134 people per square kilometer by 2050.
- Nearly 34% of the island population lives in high-risk landslide-prone areas of the country, making the island’s central hills highly susceptible to disaster impacts.

Can two Amazons survive? Invisible e-waste is poisoning the world
- E-waste, which refers to discarded electrical or electronic devices, is the fastest growing domestic waste stream in the world, and it is highly toxic, threatening public health. Much of this e-waste, largely produced by rich countries, is dumped in poor countries, with Asia and Africa major destinations.
- Because poor countries mostly lack the highly sophisticated equipment and processes needed to dismantle and recycle these complex composite products safely, unskilled scrap workers, including children, plunder them for resalable components, often with a disastrous impact on their health and the environment.
- Increasingly, the torrent of discarded cell phones and obsolete computers is greatly exacerbated by invisible e-waste: a vast, varied plethora of microchip-containing products, ranging from vaping devices to e-readers, toys, smoke detectors, e-tire pressure gauges and chip-containing shoes and apparel.
- Invisible e-waste greatly adds to developing world recycling challenges. The U.N. Environment Programme warns that “the increasing proliferation of technological devices has skyrocketed the amount of electronic waste worldwide” with nations now facing “an environmental challenge of enormous dimensions.”

Scientists chart a new source, and length, for Africa’s famous Zambezi River
- Historically, the Zambezi River in Southern Africa was believed to begin its journey at a spring in northwestern Zambia.
- A new study suggests the river actually starts off in a shallow depression in Angola’s southern highlands, at the source of a river called the Lungwebungu, giving the Zambezi a new total length of 3,421 km (2,126 mi), or 342 km (213 mi) longer than previously thought.
- The Lungwebungu and several other Angolan rivers contribute about 70% of the water reaching Victoria Falls, making them critical to the long-term health of the Zambezi and the people and wildlife who depend on it.
- The study highlights the importance of protecting the Upper Zambezi Basin, where another recent study recorded significant forest loss over the past three decades.

Peru’s Río Abiseo park yields new marsupial, hinting at more undiscovered species
- Brazilian researcher Silvia Pavan organized an expedition to a remote protected area in the Peruvian Amazon to search for a species of squirrel last observed 30 years ago.
- During the expedition, the team discovered a new species of mouse opossum, a type of marsupial, which they named Marmosa chachapoya.
- This new species is distinguished by its reddish-brown fur, yellow-grayish belly, and long, narrow face.
- The eastern Andes of Peru is notable for its high endemism, but remains largely understudied, researchers say.

SE Asia forest carbon projects sidelining social, biodiversity benefits, study finds
- Across Southeast Asia, forest carbon projects intended to offset greenhouse gas emissions are falling short on social justice safeguards, according to recent research.
- The study identifies weak governance, land tenure conflicts, corruption and fragmented policies as contributing to the shortcomings.
- Well-managed forest carbon initiatives have an important role to play in global efforts to reduce emissions, the researchers say, but they must center the rights of traditional custodians of forests.
- Against the backdrop of global democratic backsliding, experts urge greater scrutiny of project accountability to uphold social and environmental standards within the carbon sector.

The valuable peatlands of Peru’s Pastaza River Fan: one of the world’s largest carbon reservoirs
- In Peru’s Datem del Marañón province, local communities are combining ancestral knowledge with scientific expertise to protect the peatlands that thrive in this part of the Amazon.
- Peatlands cover only 3% of Earth’s surface, yet can store up to five times more carbon dioxide per hectare than other tropical ecosystems.
- Although research on Peru’s peatlands remains limited, their importance lies in both their role in mitigating climate change and their socioeconomic value for local communities.
- The area that’s the focus of scientists’ research and local communities’ conservation work is part of the Pastaza River Fan, Peru’s largest wetland and the third-deepest peatland in the world.

Small grants can empower the next generation of conservationists
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. Paul Barnes, who leads the Zoological Society of London’s EDGE of Existence program, has spent the past few years listening to the frustrations of early-career conservationists. The stories are rarely about fieldwork itself. They’re about making rent, juggling […]
First state-authorized killings mark escalation in California’s management of wolves
- California’s wildlife department killed four gray wolves in the Sierra Valley in late October, in a dramatic escalation of tactics to address growing predation of cattle by the canids and despite protection under state and federal endangered species laws.
- The department says the wolves killed at least 88 cattle in Sierra and Plumas counties and continued to target livestock despite months of nonlethal deterrents deployed to drive them away.
- The state employed lethal action despite its compensation program, which pays ranchers for cattle killed by wolves, and additional federal subsidies paid to the livestock industry at large.
- The state wildlife agency confirmed a new pack –– the Grizzly pack–– earlier this week with two adults and a pup. Though the state’s wolf population remains small and vulnerable, ranchers are increasingly concerned about livestock deaths.

Indian megacities are sinking putting thousands of buildings at risk: Study
Parts of Delhi, Mumbai, Chennai, Kolkata and Bengaluru, India’s largest cities, are slowly sinking, mainly due to overextraction of groundwater, according to a recent study, reports Mongabay India’s Manish Chandra Mishra. Researchers used eight years of satellite radar data and found that 878 square kilometers (339 square miles) of land across the five megacities show […]
Saving forests won’t be enough if fossil fuels beneath them are still extracted, experts warn
- A new analysis finds that tropical forests in 68 countries sit atop fossil fuel deposits that, if extracted, would emit 317 billion metric tons of greenhouse gases — more than the remaining 1.5°C (2.7°F) carbon budget — revealing a major blind spot in global climate policy.
- Because Brazil’s proposed Tropical Forest Forever Facility (TFFF) focuses only on stopping deforestation, researchers warn it risks missing far larger emissions from potential oil, gas and coal extraction under protected forests.
- India, China and Indonesia hold the largest fossil reserves beneath forests, with Indonesia facing acute trade-offs as most of its coal lies under forest areas where mining threatens biodiversity and Indigenous communities, including rhino habitats in Borneo.
- Experts say that compensating countries for leaving fossil fuels unextracted — through mechanisms like debt swaps or climate finance — could unlock massive climate benefits, but fossil fuel phaseout remains excluded from TFFF negotiations despite growing calls to include it.

Island-confined reptiles face high extinction risk, but low research interest
Reptile species found only on islands are significantly more vulnerable to extinction than their mainland counterparts, yet remain vastly overlooked by researchers, according to a recent study. “Reptiles, partly due to their ability to endure long periods without food or water, are particularly effective island colonizers,” Ricardo Rocha, study co-author and an associate professor at […]
Botanists decode secret life of rare plants to ensure reintroduction success
- Working with South African daisies, Colombian magnolias and Philippine coffee trees, botanists the world over are discovering the secrets to bringing extremely rare and threatened plants back from the brink of extinction. Reintroductions are often the only way to build back thriving populations, but scientists face numerous hurdles.
- A major barrier is lack of botanical knowledge about rare species, making it hard to produce sufficient viable seeds, determine triggers for germination, and identify suitable seedling habitat. If seeds aren’t available from rare plants, botanists must use cuttings to propagate plants.
- Newly established plant populations often need help in the face of numerous threats. Climate change, for example, can not only create harsh new growing conditions but also fuels the spread of plant pests. Young plants frequently need to be protected from human activities like poaching, intentional burning or land-use change.
- While it can take decades for reintroduced plants to grow into sustainable, self-replenishing populations, project funding is often limited to three years or less, especially in the Global South. Experts say they hope funding will increase as recognition grows that ecosystem restoration requires plant diversity, including rare species.

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 […]
‘Forever chemical’ contamination could undermine sea otters’ fragile recovery in Canada
- Sea otters living along the coastline of Canada’s British Columbia province are exposed — and absorb — forever chemicals, a new study shows.
- Each of the 11 sea otters tested carried residues PFAS chemicals, with concentrations higher for those living near dense human populations or shipping lanes.
- The Canadian government released an assessment earlier this year recommending that PFAS be classed as toxic and is moving toward adopting tighter rules for these chemicals. Environmentalists support the initiative.

In Thailand, a cheap bottle crate hack gives tree saplings a fighting chance
- A recent study in Thailand finds that raising native tree seedlings inside repurposed bottle crates improves performance compared to standard methods in community-run nurseries.
- Saplings grown in bottle crates had better root formation and superior growth when planted out in a deforested site, thanks to better air circulation for the roots.
- Crating the saplings also saved on labor costs, which more than offset the cost of purchasing the crates.
- Adoption of the new method could improve the quality of saplings grown in community nurseries, a benefit for reforestation projects where sapling survival is key to success.

Game of tiny thrones: Parasitic ants grab power by turning workers against their queen
Queens of some ant species have evolved an unusually hostile mode for colony takeover: they infiltrate colonies of other ant species and manipulate the worker ants into killing their own queen — their mother — then accepting the intruding queen as their new leader, according to a recent study. In the world of ants, where […]
Pioneering primatologist in Madagascar shares decades of conservation wisdom
Patricia Wright, a pioneering primatologist who established the Centre ValBio research station in Madagascar, began her work there in 1986. As the person who first described the golden bamboo lemur (Hapalemur aureus) to Western science, her contributions led to the creation of Ranomafana National Park, now a UNESCO World Heritage Site. She joins the Mongabay […]
Trade in marine fish for aquariums includes threatened species, lacks oversight: Study
- A new study of major U.S.-based online retailers of marine fish bound for aquariums found that nearly 90% of traded species are sourced exclusively from the wild, including a number of threatened species, and that the trade is poorly tracked.
- The study raises concerns about the ecological impact of the trade on marine ecosystems, including around coral reefs, in countries such as Indonesia and the Philippines, where the fish are caught.
- Experts called for more work to develop sustainable fisheries and aquaculture in coastal communities in the Global South, and for building consumer awareness and establishing eco-certification schemes.

Top ethnobotanist Mark Plotkin’s COP30 reflections on Amazon conservation (analysis)
- The global battle to mitigate climate change cannot be won in the Amazon, but it can certainly be lost there, writes top ethnobotanist Mark Plotkin in a new analysis for Mongabay. Though he’s well-known for investigating traditional uses of plants in the region, he’s also a keen observer of and advocate for Indigenous communities and conservation there.
- Compared to the 1970s, he writes, the Amazon enjoys far greater formal protection, understanding and attention, while advances in technology and ethnobotany have revealed new insights into tropical biodiversity, and Indigenous communities — long the guardians and stewards of this ecosystem — are increasingly recognized as central partners in conservation, and their shamans employ hallucinogens like biological scalpels to diagnose, treat and sometimes cure ailments, a technology that is increasingly and ever more widely appreciated.
- “The challenge now is to ensure that the forces of protection outpace the forces of destruction, which, of course, is one of the ultimate goals of the COP30 meeting in Belém,” he writes.
- This article is an analysis. The views expressed are those of the author, not necessarily of Mongabay.

Newly described ‘lucifer’ bee found visiting critically endangered plant in Australia
In 2019, researcher Kit Prendergast was surveying the insects visiting an incredibly rare plant in the Bremer Ranges of Western Australia when a bee grabbed her attention. Prendergast and her colleague dug deeper and found that the native bee, now named Megachile lucifer, is a new-to-science species, according to a recent study. The species name […]
Iguanas on Mexico’s Clarion Island likely native, not introduced by people: Study
Researchers have long speculated that humans introduced spiny-tailed iguanas to Mexico’s remote Clarion Island about 50 years ago. However, a recent study suggests the Clarion iguanas are likely native to the island, arriving long before human colonization of the Americas. Clarion Island is the westernmost and oldest of a small group of islands in Mexico’s […]
Turning outdoor exploration into environmental discovery: Gregg Treinish and the rise of Adventure Scientists
- Gregg Treinish, founder of Adventure Scientists, has built a global network of trained volunteers who collect high-quality environmental data for researchers, agencies, and conservationists. His organization bridges the worlds of outdoor adventure and scientific rigor.
- From microplastics and illegal timber to biodiversity mapping, Adventure Scientists’ projects have filled crucial data gaps and influenced policy, research, and corporate practices around the world.
- In California, Treinish’s team is partnering with the California All-Taxa Biodiversity Inventory (CalATBI) to help catalog the state’s immense diversity through thousands of insect and soil eDNA samples collected by volunteers.
- Treinish spoke with Mongabay founder and CEO Rhett Ayers Butler in October 2025 about scaling trust-based citizen science, the value of human observation in nature, and why adventure remains a powerful gateway to environmental action.

Asian golden cat range expands, but declines continue amid rising threats
- The Asian golden cat (Catopuma temminckii) is a medium-sized cat species that was once abundant across Asia, ranging from India to China. Today its population is undergoing a significant decline.
- That’s resulted in it now being declared a threatened species as its habitat is lost or fragmented, and indiscriminate snaring removes it from forests, particularly in Southeast Asia.
- Targeted research, conservation and funding are rare for this species, resulting in significant knowledge gaps about its basic ecology and threats. That uncertainty is causing some conservationists to say it could warrant endangered status.
- It’s hoped that increasing threat levels imperiling the Asian golden cat will spur donor funding, giving researchers the tools to shine a light on the needs of this lesser-known felid. Nepal has so far led the way in conservation efforts.

Europe’s under-pressure bats face ‘astonishing’ threat: Ambush by rats
Researchers have captured video of an unexpected predator at two bat hibernation sites in northern Germany: invasive brown rats that lie in wait to intercept the bats mid-flight. Invasive rodents are known predators of native animals on islands, including bats. However, this is likely the first time invasive brown rats (Rattus norvegicus) have been recorded […]
Vietnam’s protected areas fall short of safeguarding most bats, study finds
- Bats play crucial roles in biodiverse ecosystems the world over, yet they’re often overlooked in conservation planning.
- New research from Vietnam indicates the existing network of protected areas fails to adequately safeguard the small flying mammals, risking continued population declines.
- The study identifies priority areas where Vietnam’s efforts to expand its protected area network would most benefit bats in the central highlands, the western central coast and the northwest regions.
- Experts say a lot could be achieved for bats in Southeast Asia by ending the illegal wildlife trade, particularly the “frivolous” international ornamental bat trade.

Report identifies 10 emerging tech solutions to enhance planetary health
- A recent report underlines 10 emerging technologies offering potential to accelerate climate action, restore ecosystems, and drive sustainable innovation within safe planetary boundaries. These technologies include AI-supported Earth observation, automated food waste upcycling, green concrete and more.
- Innovative AI improvements in Earth observations (EO) can better identify and track human-caused environmental impacts and offer improved early warning alerts for planetary boundary overshoot. Such systems use AI-powered analytics to synthesize satellite, drone and ground-based data for near-real-time results.
- Artificial intelligence and automation can also work in tandem to manage citywide food waste programs, ensuring that food scraps are diverted from landfills or incineration, decreasing carbon emissions and reducing waste.
- Another tech solution is green concrete which could not only reduce emissions from traditional cement production, but when incorporated into infrastructure construction, can offer a permanent storage place for captured CO2.

India’s Ganga River drying at unprecedented levels
The Ganga River, which sustains the lives of at least 600 million people, is facing its worst dry spell and lowest streamflow in 1,300 years, according to a recent study, reports Mongabay India’s Simrin Sirur. Researchers extrapolated the Ganga’s water levels going back to the year 700 C.E. using a combination of paleoclimatic and historical […]
In Mauritius, an NGO is tracking the sex life of corals to save them
- Mauritius will soon be home to one of the largest projects in the Western Indian Ocean aimed at restoring corals through sexual propagation.
- The scientific research for the Odysseo coral restoration initiative is led by U.S.-based nonprofit Secore, which has also worked in the Caribbean Sea and reported success in breeding heat-tolerant corals.
- The initiative aligns with a recent policy push by the Mauritian government to promote coral restoration through sexual propagation as opposed to through asexual methods.
- However, this method of coral restoration is in its nascency in this region, and Secore is currently focused on gathering knowledge that will help it choose species to breed, donor sites to collect sperm and egg cells, and transplanting sites for newly grown coral.

With ‘terrifying’ trade in African hornbills, scientists call for increased protection
- With an alarming rise in the international trade of African hornbills, wild populations are plummeting. As key seed dispersers, their demise also threatens the survival of the forests they inhabit.
- According to recent studies, the United States is a major market for African hornbills, with more than 2,500 individuals or their parts imported into the country between 1999 and 2024. Another 500 were traded online from 2010 to 2024.
- Although the drivers of the trade are unknown, West and Central Africa are trade hotspots, with Cameroon and the Democratic Republic of Congo being the main source countries.
- The international trade in African hornbills is currently unregulated, unlike that of their Asian counterparts. But a proposal to control this trade is on the agenda at the upcoming CITES meeting, which conservationists say is the first step to rein in unsustainable trade.

Potential wind slowdown threatens renewable energy and fuels heat domes
Climate change may be causing long-term global wind speeds to slow down, a shift that will likely lead to a dangerous rise in local temperatures, worsening air pollution and disruption to renewable energy systems, Mongabay writer Sean Mowbray reported. A warming atmosphere is likely weakening the forces that govern wind speeds, leading to more frequent […]
Study reveals overlooked cultural threat to wildcats across Africa
- The role that cultural demand plays in driving hunting and trade of many species of wildcats is poorly understood.
- Research commissioned by the wildcat conservation NGO Panthera found widespread use across Africa by traditional leaders, healers and participants in cultural ceremonies. Leopards were the most commonly identified species, followed by lions, servals and cheetahs.
- The researchers say recognizing the cultural contexts in which carnivores are used can help conservationists design interventions that are culturally sensitive and locally relevant.

Negro River study finds genetic damage in fish after oil spill
- Scientists assessed harmful effects on Amazonian fish after a barge capsized in 2013 with approximately 60,000 liters of petroleum asphalt cement in Manaus.
- Although the concentration of the contaminant decreased with rising water levels, the fish continued to exhibit effects of exposure three months after the accident, including DNA damage and neurotoxicity.
- The Negro River’s waters are rich in dissolved organic matter, which may increase the toxicity of the chemical compound.
- This research adds to other studies that attest to the harmful effects of oil on vertebrates, aquatic insects and plants in the Amazon, given the pressure for greater exploration in the region.

Scientists describe new-to-science mouse opossum from Peruvian Andes
Scientists have described a new species of mouse opossum discovered in 2018 in the cloud forests of the Peruvian Andes, 2,664 meters (8,740 feet) above sea level. The find was reported by Mongabay Latam staff writer Yvette Sierra Praeli. The new marsupial is named Marmosa chachapoya after the ancient Chachapoya people who once lived in […]
New cluster of Tapanuli orangutans discovered in Sumatra peat swamp
- Researchers have confirmed that the critically endangered Tapanuli orangutan, previously thought to live only in Sumatra’s Batang Toru forest, also inhabits a peat swamp forest 32 kilometers (20 miles) away in the Lumut Maju village forest.
- DNA analysis of fecal samples verified the Lumut Maju apes as Tapanuli orangutans, marking the first confirmed record of the species outside Batang Toru.
- The discovery highlights the conservation value of nonprotected peat swamps, which are rapidly being cleared for oil palm plantations, threatening the orangutans’ survival.
- Conservationists warn that the isolated Lumut Maju population, likely fewer than 100 individuals, may not be viable long term unless habitat protection or relocation strategies are implemented.

Vast freshwater reserves found beneath Atlantic seafloor
Scientists recently discovered vast freshwater reservoirs beneath the Atlantic seafloor, stretching off the U.S. East Coast from the states of New Jersey to Maine. The find was “a beautiful scientific accident,” Brandon Dugan, a professor of geophysics at the Colorado School of Mines, U.S., and co-chief scientist on the expedition, told Mongabay in a video […]
‘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.

Biodiversity loss due to land use change could be highly underestimated: Study
- New research carried out in Colombia by the University of Cambridge suggests that local surveys assessing the effect of land clearances on biodiversity may be underestimating the impact by as much as 60%.
- To fully understand the effects of clearing forests for pastureland, much surveys of a much larger scale are required to reflect the different levels of biodiversity in regions and habitats and their resilience to change.
- More accurate species surveys, the authors say, could also support future programs such as biodiversity offsetting schemes as well as influencing farming policies.

World’s 1,500th known bat species confirmed from Equatorial Guinea
From Bioko Island in Equatorial Guinea, researchers have described what is officially recognized as the 1,500th bat species known to science, according to a recent study. The newly described bat is a species of pipistrelle, a group of tiny insect-eating bats, and scientists have named it Pipistrellus etula, with etula meaning “island” or “nation” in […]
Tanzanian conservationists mourn death of plant expert Aloyce Mwakisoma
- Aloyce Mwakisoma, a renowned plant expert from Tanzania’s Udzungwa Mountains, was struck and killed by a bus on Oct. 6 near the village of Sanje.
- Mwakisoma, who was born and raised in the Udzungwas, had an encyclopedic knowledge of the plants and animals found in his home in the Eastern Arc.
- His colleagues recognized him as one of the many local experts whose indigenous knowledge powerfully informs the description and protection of the continent’s biodiversity.

First oarfish sighting in Sri Lanka highlights citizen science in marine protection
- Scientists have documented the first-ever record of an oarfish (Regalecus russellii) in Sri Lanka, a 2.6-meter (8.5-foot) specimen caught off the country’s western coast.
- The find expands the known distribution of oarfish into the Indian Ocean, offering a new baseline for studying this rarely seen deep-sea species.
- Meanwhile, another oarfish was recorded in India’s Tamil Nadu this year, while within 20 days, three oarfish have been recorded from Australia and New Zealand, puzzling naturalists.
- The importance of promoting citizen science and raising awareness among fishers is needed.

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.

Big Oil isn’t part of the clean energy push, despite its claims, study shows
A new study that mapped the portfolios of the world’s 250 biggest oil and gas companies found their deployment of renewable energy is paltry: they’re responsible for just 1.42% of the global renewable energy capacity in operation. Despite announcing ambitious plans to embrace renewables, a mere 0.1% of the primary energy they produce comes from […]
Study busts big bad myth that wolves are growing fearless of humans
- As wolves return to parts of their historical ranges in Europe and North America, there’s growing concern that the predators are becoming less fearful of people.
- But a recent study from Poland shows that wolves still fully fear people, a finding that extends to other top predators and wildlife elsewhere around the world, where the fear of humans is “ingrained.”
- In May, wolves were moved to a lesser protected status in the EU, partly based on the argument that the canids are becoming fearless of humans.
- However, the study’s authors say that safety from wolves requires behavioral change on the part of humans, including keeping food and livestock secure and away from the canids.

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.

Amazon Rainforest hits record carbon emissions from 2024 forest fires
In 2024, the Amazon Rainforest underwent its most devastating forest fire season in more than two decades. According to a new study by the European Commission’s Joint Research Centre, the fire-driven forest degradation released an estimated 791 million metric tons of carbon dioxide in 2024, a sevenfold increase compared with the previous two years. The […]
Marine life are thriving on Nazi missile debris in the Baltic Sea: Study
As Germany demilitarized after World War II, it dumped massive amounts of its leftover munitions into the Baltic Sea. A recent study has found that some of those submerged weapons, which are still releasing toxic compounds, now host more marine organisms than the sediments around them. In October 2024, researchers used a remotely operated vehicle […]
Scientists rethink Serengeti migration numbers with satellite, AI tools
- An AI-powered satellite survey has found that the number of wildebeests migrating across Kenya and Tanzania annually might be less than half of the million-plus figure that’s widely touted.
- The authors of the study said their findings underscore the need to calibrate the findings from different surveying methods in order to accurately estimate wildebeest numbers.
- The wildebeest migration is one of the largest mammal migrations in the world, with the animals migrating 800 kilometers (500 miles) in search of better grass.
- Estimating accurate numbers of migrating wildebeests is essential to keep track of the population in the face of habitat loss and increased human presence.

Study warns up to a quarter of Philippine vertebrates risk extinction
- A new study warns that 15-23% of the Philippines’ 1,294 terrestrial vertebrates face extinction, with amphibians and mammals at highest risk.
- Endemic species are most vulnerable, yet many lesser-known taxa like flying foxes, Cebu flowerpeckers and island frogs receive little research or funding compared to charismatic species such as the Philippine eagle and tamaraw dwarf buffalo.
- Habitat loss, overhunting and the wildlife trade remain the leading threats, while research gaps and bureaucratic hurdles hinder effective conservation planning.
- Experts say the findings should guide the updated Philippine Biodiversity Strategy and Action Plan, prioritizing poorly studied species and high-risk sites not yet covered by protected areas.

There’s far less land available for reforestation than we think, study finds
- In recent years, policymakers have made pledges for huge tree-planting projects a cornerstone for meeting national carbon reduction goals, while doing little to seriously cut fossil fuel emissions. But a new study shows the carbon sequestration estimates made for those forestation projects may be wildly optimistic.
- The new research determined that land found suitable for forestation in past studies — an area about the size of India — shrank by as much as two-thirds when adverse impacts on biodiversity, food security and water resources were taken into account.
- When the new study figured in environmental and social constraints, the potential for existing tree-planting pledges to store a promised 40 gigatons of carbon by 2050, was reduced to just 12.5 gigatons — a significant sum, but far from what’s needed to offset continued fossil fuel use.
- The new study urges policymakers to be more pragmatic in their planting strategies, and prioritize lands best slated for permanent reforestation. Other researchers urge decision-makers to put more effort and money into protecting already existing biodiverse forests, which hold high carbon storage potential.

Urban appetite for lemur meat piles pressure on iconic primates
- Thousands of threatened lemurs are killed by specialist hunters every year to feed a lucrative urban market for their meat in cities across Madagascar.
- While rural subsistence hunting is seasonal and opportunistic, the year-round urban luxury trade for lemur meat threatens large-bodied species, including during key reproductive periods.
- Primatologists recently issued a statement calling for strategies aimed at different actors involved in lemur meat hunting, including stricter gun regulations and enforcement directed at the urban trade, and the development of economic alternatives for rural subsistence hunters.

Climate change puts pressure on reindeer populations, both wild & domestic herds
- In Finland’s Arctic, unpredictable weather events pose a threat to reindeer herding, a traditional livelihood for the Indigenous Sámi people.
- Due to climate impacts, the global reindeer population could decline by more than 50% by 2100, with the steepest declines expected in North America, at 84%, and population increases predicted in northern Asia, according to a study.
- The impacts of climate change also affect semidomestic reindeer herds, according to researchers, and additional pressures, such as logging old-growth forests and expanding extractive activities on grazing lands, shrink their access to food sources.
- Sustainable land management, such as protecting ecological corridors and old-growth forests, plays a vital role in maintaining reindeer populations and preserving migration routes, one author says.

Jaguar in Brazil swims 2.3 km in longest recorded distance for the species
Biologists in Brazil have documented a jaguar swimming an estimated 2.3 kilometers, or 1.4 miles, across an artificial reservoir in the Cerrado savanna, the longest confirmed swim by the species to date. The previous scientific record, published in 1932, was of a jaguar swimming 200 m (660 ft). “We knew that jaguars might have this […]
First review of Amazon plastic pollution finds widespread contamination
Plastic pollution is widespread across the Amazon Rainforest’s rivers, plants and animals, according to a recent study. Previous research suggests up to 10% of total plastics in the ocean arrive there via the vast network of waterways that’s the Amazon Basin. To understand how and where plastic pollution is present within the basin itself, researchers […]
The fate of flying rivers could decide Amazon ‘tipping point,’ report says
- The Amazon’s “tipping point” refers to the transition of the rainforest into a drier, savanna ecosystem. The rainforest’s ecological balance depends on the transport and recycling of moisture, but deforestation has been shown to disrupt the region’s water cycle.
- Moisture moves east to west, from the Atlantic Ocean across the Amazon Basin via what scientists call “aerial” or “flying rivers,” a critical mechanism in the region’s water cycle.
- A new report from Amazon Conservation’s Monitoring of the Andes Amazon Project identified areas of deforestation that disrupt these flying rivers from hundreds of miles away. It also found that not all parts of the Amazon have the same tipping point.
- The researchers stressed the need for regional, transboundary conservation efforts that account for varied threats in different parts of the Amazon.

Long-lost white shark tag traces remarkable journey from South Africa to SE Asia
- The discovery of a satellite tag from a subadult female white shark in Indonesia marks the first recorded connectivity of white shark movement between South Africa and Southeast Asia.
- The white sharks found in South Africa and Australia belong to different genetic pools, which makes the two populations distinct from one another, even though they share the same migratory route.
- The biggest threats facing white sharks in South Africa and Indonesia are unsustainable fishing, where the sharks become both the bycatch and main catch.
- While there are attempts to support local fishers to pioneer shark conservation instead of hunting them, such efforts are thwarted by lack of funding.

Grue jay or Bleen jay? Researchers confirm hybrid between blue and green jays
Researchers have for the first time confirmed that a blue jay and a green jay have mated in the wild to produce a rare hybrid with mixed features. Spotted by a birder named Donna in her backyard in San Antonio in the U.S. state of Texas, this hybrid may have resulted from the two jay […]
Turning camera traps into real-time sentinels: Interview with Conservation X Lab’s Dante Wasmuht
- Wildlife technology nonprofit Conservation X Labs has developed and deployed an AI-powered device to make real-time monitoring of camera-trap images easier and more seamless.
- The Sentinel device can be attached to camera traps and serves as a minicomputer with built-in AI models.
- The device has been deployed around the world, and has found applications in detecting invasive species in New Zealand and in the Florida Everglades.
- While camera traps are widely used in conservation, it’s often a challenge to retrieve the data from remote locations, often leading to a delay in conservation action and management.

Ocean acidification threatens planetary health: Interview with Johan Rockström
- The newly published 2025 Planetary Health Check report confirms transgression of the ocean acidification planetary boundary — the seventh Earth system threshold crossed, putting a “safe operating space for humanity” at risk. Oceans act as a key climate stabilizer, resilience builder and Earth life-support system.
- Marking the launch of the 2025 Planetary Health Check, Mongabay speaks with report co-author and renowned Earth system scientist Johan Rockström about how the transgression of planetary boundaries is eroding environmental justice — the right of every human being to life on a stable, healthy planet.
- Rockström, who led the international team of scientists who originated the 2009 planetary boundary framework, also speaks about the failure to achieve a U.N. plastics treaty in August and the challenge of accomplishing planetwide sustainability in a time of widespread armed conflict and political instability.
- He likewise emphasizes the need to bring the U.S. back to the negotiating table at COP30, the U.N. climate summit scheduled for November, in Belém, Brazil, and addresses the importance of inserting the planetary boundaries framework into those talks.

Global CO2 storage capacity may be drastically overstated, study finds
- The storage available for safe carbon storage could be far lower than current estimates, according to a new study.
- Carbon capture and storage (CCS) has been touted as a viable method for drawing billions of tons of CO2 out of the air, typically securing it in rock formations deep underground.
- However, this new analysis suggests that many locations suitable for carbon storage may also pose risks, such as water contamination or earthquakes.
- That finding led the study authors to conclude that the “prudent” available storage is much less than has been estimated.

Timing, not traits, helps California’s jewelflowers adapt to diverse landscapes
- California’s native jewelflowers, a group of plants that belong to the mustard family, grow in widely diverse landscapes and microclimates across the state. But until now, scientists didn’t understand what allowed their wide distribution.
- To understand this, researchers analyzed information from nearly 2,000 specimens; dug into climate and geological databases; and amassed field observations to understand the climatic conditions that 14 species of jewelflowers need to grow and reproduce.
- Their study found that, despite living in different landscapes, from desert to valleys and mountains, jewelflowers prefer hotter and drier climates, timing their sprouting and flowering accordingly. Even those species growing in colder regions adjust their life cycle to flower later in the summer and seek drought-prone soils.
- The research shows how plants distributed across vast geographies may require specific microclimates and habitats to survive, which are potentially at risk in a warming world.

Most Caribbean coral reefs to stop growing by 2040, study warns
Most coral reefs in the Caribbean could stop growing, and even start eroding away, by 2040 if global warming continues unchecked, a new study finds. Coral reefs, especially those near shores, protect valuable coastlines from flooding during cyclones and storm surges by breaking up wave energy. For the reefs to continue to act as natural […]
Mozambican reserve harbors largest documented breeding population of rare falcon
- A new study estimates Niassa Special Reserve in Mozambique hosts 68–76 breeding pairs of Taita falcons, likely the world’s biggest population of the rare raptor.
- Niassa’s granite inselbergs provide hunting advantages over larger falcons, allowing the Taitas to thrive.
- Woodland clearance, charcoal production, agriculture and domestic fowl could shift the balance in favor of peregrines and lanners, but conservation measures and the resilience of miombo woodlands offer hope.
- Once-healthy populations in South Africa and Zimbabwe have collapsed, underscoring Niassa’s importance for the species’ survival.

No new record low for Arctic sea ice loss in 2025
- Arctic sea ice hit its 2025 summer minimum without setting a record low on Sept. 10, despite a historically low winter maximum earlier in the year.
- Scientists say sea ice loss has slowed over the past 20 years due to natural variability in atmospheric and ocean systems, counterbalancing the impacts from human-caused climate change.
- However, researchers warn that this slowdown likely offers only a temporary reprieve, and that the continued escalation of global warming could cause rapid sea ice loss before 2050.
- The U.S. National Snow and Ice Data Center for the first time switched to using Japanese sea ice data after losing access to key U.S. military satellite data, which had allowed for a continuous Arctic sea ice record since 1979.

Warming triggers unprecedented carbon loss from tropical soils, study finds
- Tropical forests exchange more CO2 with the atmosphere than any other terrestrial biome, meaning that even a relatively small shift in the balance of carbon uptake and release there could have a big impact on global climate. Despite this, research on tropical soil responses to warming has lagged behind.
- In a field experiment in Puerto Rico, researchers used infrared heaters to warm understory plants and topsoil by 4° Celsius. Warming significantly increased soil carbon emissions, but terrain also had a major impact: A warmed plot at the top of a slope showed an unprecedented 204% increase in CO2 emissions after one year.
- Carbon emissions from plots lower on the slope increased between 42% and 59% in response to warming — in line with the results from the only other long-term tropical soil warming experiment to date. However, the upper-slope response represents the largest change in any soil warming experiment conducted globally.
- The new study results add to a growing body of evidence that tropical soils are far more sensitive to warming than previously thought. If elevated tropical soil CO2 releases persist in the long term, it could have dire consequences for Earth’s climate. But the soil biome may adjust over time, so future effects remain unclear.

Madagascar’s dry forests need attention, and Verreaux’s sifakas could help
- Western Madagascar is home to some of the country’s poorest communities and its most endangered wildlife, presenting intertwined challenges for conservation.
- The region’s characteristic dry forests have been badly damaged by clearing of land for shifting agriculture — and for mining, plantations and timber harvesting — over the past 50 years: Across Madagascar, nearly 60% of dry forest species are classed as vulnerable, endangered or critically endangered.
- NGO leaders, scientists and government representatives are forming a dry forest alliance to better coordinate efforts to protect this valuable biome.
- Among the new alliance’s first actions was pushing for the inclusion of the critically-endangered Verreaux’s sifaka on the latest list of the World’s 25 Most Endangered Primates, which alliance members hope will attract greater attention to this primate’s threatened habitat.

More deforestation leads to a drier dry season, Amazon study finds
- Between 2002 and 2015, forest loss in Brazil’s southern Amazon reduced the amount of rainfall during the dry season by more than 5%, a recent study found.
- Researchers studying how deforestation in the states of Rondônia and Mato Grosso affected the atmospheric water cycle between 2002 and 2015 found that a reduction in forest cover reduced evapotranspiration and disrupted regional atmospheric systems.
- Lower rainfall during the dry season can compromise crops, boost wildfires, and reduce water supplies and river levels, sometimes leaving communities isolated.

An elusive deer species clings to survival in Sri Lanka’s south
- The hog deer (Axis porcinus), Sri Lanka’s most threatened deer species, is classified as critically endangered in the country and survives only in fragmented habitats in the island’s southwest.
- A year-long survey recorded 306 adults and 22 fawns, showing a modest increase in their numbers, but an array of threats continues to put pressure on the species’ survival.
- Conservationists warn against major threats including attacks by feral dogs and water monitors, road accidents and habitat loss, while garbage dumping alters predator dynamics, adding a fresh threat.
- Debate continues over whether Sri Lanka’s hog deer is native or introduced, with fossil evidence hinting at an ancient presence but some theories indicating colonial-era introductions.

Researchers describe three new-to-science snailfish species off California coast
In 2019, researchers surveying the seafloor off the coast of California came upon three unusual species of small fishes with large heads: one with bumpy pink skin, and the other two both black in color. The team collected the fish using underwater research vehicles and later analyzed their DNA and bodies. Their analysis showed that […]
Post-Blob, California’s kelp crisis isn’t going away
- Kelp forests function as major habitat for marine biodiversity, but are in rapid decline worldwide, largely because of climate impacts on the oceans.
- A 2013 marine heat wave known as “the Blob,” combined with the mass die-off of sea stars, caused a 95% loss of Northern California’s kelp forests.
- The loss of sea stars allowed the purple urchins that they thrive on to spread rapidly, converting lush kelp forests into “urchin barrens” in parts of California. There’s been very little recovery since.
- Restoration of kelp forests is extremely difficult and requires far more resources than are currently being committed.

How climate change could affect production of the world’s favorite fruit, the banana
- Bananas make up one of the largest tropical fruit export chains, with 20 million metric tons of bananas exported annually; a whopping 100 billion bananas are eaten globally each year.
- According to a recent study, the area suitable for export banana production in Latin America and the Caribbean could be reduced by 60% due to climate change and other factors, such as population density and distance from ports.
- Research highlights that countries located in the Global South may find it more difficult to adapt to climate change than wealthier countries due to a lack of resources.
- Although the study focuses on large, intensive banana plantations, researchers say small farmers could also be affected by climate change; however, they may be more resilient to climate shocks because they often use a production system that values crop diversity.

Sri Lanka monkey survey sparks skepticism & oddball ideas for deterring crop raiders
- In March, an islandwide five-minute rapid visual census conducted in Sri Lanka estimated populations of crop-damaging wildlife at about 6.5 million monkeys, 2.7 million giant squirrels, and 4.7 million peafowl.
- While the accuracy of the survey has been strongly questioned, there is broad agreement on the urgent need for solutions, as these species cause considerable damage to crops.
- Several solutions have been proposed, one of them is to use predatory scents, particularly leopard urine, as a natural repellent to deter monkeys citing successful use of predator scents like coyote and wolf elsewhere.
- This idea has drawn mixed reactions, with some citing practical challenges in implementation, while others recommend further study and testing of the method to address the problem of crop raiders.

Scientists tap ‘secret’ fresh water under the ocean, raising hopes for a thirsty world
ABOARD LIFTBOAT ROBERT, North Atlantic (AP) — Scientists conducting a first-of-its-kind drilling operation have extracted samples of fresh water hiding in massive reservoirs deep under the ocean. Their consortium of more than a dozen nations sank pipes through the seabed muck off Cape Cod this summer to see how old that water is, what organisms […]
How do we perceive biodiversity? We can see it & hear it
- A recent study shows that people are able to perceive biodiversity through sights and sounds, and those perceptions correlate with the actual biodiversity of a natural place.
- Indigenous community members in the Democratic Republic of Congo share their experiences that affirm what the researchers found.
- The study adds to a growing body of research on biodiversity perception and its connections to human mental health and well-being.

Soil carbon: Crucial ally or potential threat to net-zero commitments?
- Earth’s top 2 meters (6 feet) of soil hold 2.5 trillion metric tons of carbon — more than is held in living vegetation and the atmosphere combined. But soil carbon sinks are under threat — global warming could trigger a positive feedback loop that seriously accelerates soil emissions, just as we take steps to decarbonize society.
- The effects of elevated temperature and atmospheric CO₂ on soil carbon have been factored into climate models. But those models don’t currently capture the true complexity of the soil carbon sink, in part because scientists don’t fully understand the mechanisms that influence soil carbon gains and losses.
- Major knowledge gaps urgently need to be addressed: How are long-term soil carbon stores protected from microbial consumption (and CO₂ release)? And how will global warming alter microbial communities, deep soil carbon, and the climate sensitivity of tropical soils (which store a third of global soil carbon)?
- Improved understanding of soil carbon dynamics could offer an opportunity to better manage agricultural and forest soils for carbon sequestration. With proper management, degraded soils could sequester a billion tons of additional carbon annually, making them a key ally in the fight against climate change.

Discovery of dazzling blue butterfly underscores peril facing Angola’s forests
- Scientists have described a new butterfly species, Francis’s gorgeous sapphire (Iolaus francisi), from Angola’s Namba Mountains, where its survival depends on mistletoe plants.
- High-altitude evergreen forests, known as Afromontane and covering about 590 hectares (1,460 acres) in the Namba Mountains, are the largest of their kind in Angola but remain without legal protection.
- Researchers warn that fires, timber harvesting, and especially unregulated farming could devastate the forests, as has happened at Kumbira, another Angolan Afromontane forest.
- Conservationists say community-led initiatives are key to protecting Namba, as Angola’s parliament moves to consider protected status for nearby Mount Moco, another Afromontane oasis.

To save humanity and nature we must tackle wealth inequality, says Cambridge researcher
Wealth inequality is a primary culprit behind the ecological and environmental collapse of societies over the past 12,000 years, which have come to be dominated by a small circle of elites hoarding resources like land, research shows. Today, instead of an isolated collapse, we face a global one, says Luke Kemp, a researcher at the […]
New bat species described from Western Himalayas
Researchers reviewing the diversity of bats in the Western Himalayas in India recently confirmed a new-to-science species from Uttarakhand state.

Rohit Chakravarty, a bat researcher and conservationist with the nonprofit Nature Conservation Foundation, […]
Scientists decode the unusual silver-blue color of an ancient South African plant
Most plants get their coloration from pigments, but an endangered South African cycad gets its unique silvery-blue hue from wax crystals and an underlying chlorophyll-rich layer, according to a recent study. Researchers say understanding how such layers work could pave the way for creating materials that protect from UV and water exposure. Cycads, sometimes described […]
Data debunks spike in Sri Lanka’s elephant killings, points at media hype
- With 238 elephant deaths reported between January and end of July this year, including several iconic tuskers that were found dead, there is increasing concerns about possible organized crime network behind the elephant killings in Sri Lanka.
- The country’s environment minister has filed a complaint with the Criminal Investigations Department (CID) and plans are afoot to deploy the Civil Defence Force to combat wildlife crime and support the severely understaffed Department of Wildlife Conservation (DWC) to address human-elephant conflict.
- Meanwhile, the government’s attempt to distribute more guns among the farming community has angered environmentalists who warn that these guns would increase elephant deaths.
- While various theories are being suggested by some regarding the recent spike in elephant deaths, including ivory poaching, hunting for meat and organized killings, data analysis by Mongabay shows there’s no significant rise, but instead points to a well-meaning media hype, with far greater coverage than before on elephant deaths.

Small islands offer big hope for conservation of endemic species, study shows
- New research in Indonesia shows that small islands, often considered extinction hotspots, can act as crucial refuges for rare mammals like the anoa and babirusa, which face severe threats from deforestation and poaching on larger land masses.
- Genetic analyses of more than 110 individuals revealed that while small-island populations have lower genetic diversity and higher inbreeding, they also carry fewer harmful mutations — likely because long-term isolation allowed natural selection to purge them.
- Smaller islands were also found to host higher-quality, better-protected forest habitats, suggesting that conserving these areas may be more effective than attempting “genetic rescue” by moving animals from mainland populations, which could introduce harmful mutations.
- The study highlights the need to refine taxonomy, prioritize protection of small-island habitats, and integrate these overlooked areas into conservation planning, as they may hold the key to the long-term survival of iconic and endemic small-island mammals.

The slow demise of turtles and tortoises
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries.

Yet despite their evolutionary stamina, these ancient mariners and land dwellers now find themselves in peril. A sweeping global assessment published in Nature […]
Sharks risk losing their bite as oceans turn acidic: Study
Sharks continually shed and regrow teeth throughout their lives, replacing worn or lost teeth with new ones. That makes them particularly good at catching prey. However, these top marine predators could lose their literal edge as ocean acidification damages their teeth and makes it harder to keep and replace them, a new study says. “Shark […]
Sunscreens protect us but also pose real planetary health concerns
- Sunscreens have become an important part of people’s sun management routine, protecting skin from harmful solar UV radiation. But many of these products contain chemicals that can be harmful to saltwater and freshwater ecosystems, while preliminary findings indicate some ingredients can have health effects.
- Ultraviolet filter chemicals and mineral components found in sunscreens can harm marine species such as corals and help trigger bleaching. In recent years, numerous studies have shown that many of these chemicals persist in the environment and can impact seagrass, fish and other marine life.
- More research is needed to understand the full environmental and health impacts of chemicals used in sunscreens. New formulations using ingredients proven to be safe are required, say analysts, and makers should improve product labelling to better inform consumers, with government regulation potentially necessary.
- Experts also urge caution, noting that while there are environmental concerns surrounding sunscreen chemicals, this should not be understood as a call not to use these products.

Shrinking Mekong megafish underlines risks to the river, study finds
- A new study has found that the Mekong River’s largest freshwater fish are shrinking in size, with critically endangered species like the giant catfish and giant barb now averaging less than half their historical size.
- Researchers analyzed more than 397,000 samples of 257 species across Laos, Cambodia and Vietnam, finding that fish longer than 60 centimeters (2 feet) are shrinking fastest, while smaller species show little change.
- Overfishing, habitat loss, dam construction, sand mining, pollution and climate change are driving the decline, raising fears of collapse in one of the world’s most important inland fisheries.
- Scientists warn the trend mirrors global declines in large freshwater species, such as in the Amazon and Nile basins, but recent discoveries of massive fish like a 300-kg stingray show it’s not too late for recovery if urgent action is taken.

Social media post sparks rediscovery of endemic Sri Lanka rainforest plant
- Classified as “extinct in the wild” in Sri Lanka’s 2012 Red List, the endemic rainforest giant known as Pini- Beraliya (Doona ovalifolia) has been rediscovered in several locations, but the first discovery of the plant was triggered by a Facebook post.
- The species was long known only from a single cultivated specimen found at the Royal Botanic Gardens in Peradeniya, which served as a living reference during decades without any wild sightings.
- Conservation efforts now include propagation of hundreds of seedlings at the Endane plant nursery in mid-country and the creation of a community-run nursery in Pimbura in southwestern Sri Lanka, where schoolchildren actively water and monitor these plants in their school premises.
- A recovery plan aims to protect all remaining wild trees, expand ex-situ collections and restore suitable riparian habitats with the help of local guardian groups.

How science links extreme weather disasters to climate change: Interview with WWA’s Clair Barnes
- Scientifically attributing extreme weather events like floods or drought to climate change versus other natural processes or human activities is tricky.
- But since 2014, the World Weather Attribution, an international network of researchers, has pioneered methods that allow them to understand the role of human-induced climate change in current extreme weather events, if at all.
- Mongabay’s Kristine Sabillo recently spoke with WWA researcher and environmental statistician Clair Barnes to learn more about how WWA conducts its rapid analyses.

Climate change tests the resilience of people and desert-adapted wildlife in Namibia
- Since Namibia’s independence in 1990, the country has become a model of wildlife recovery, and is now famed for its free-roaming herds of megafauna and emblematic national parks.
- A key to this recovery is the model of community-based natural resource management, which places much of the responsibility and benefits of wildlife conservation in the hands of rural communities, enabling people to earn income from small-scale hunting and tourism and thus motivating them to conserve wildlife.
- A recent 11-year dry spell has tested the resilience of the model and the people and natural systems that depend on it — but it also serves as an opportunity to build a more climate-resilient future for desert-adapted megafauna in habitats projected to become hotter and drier.
- Namibian conservation experts maintain that the key to wildlife survival is to cement their economic value in policies: if the people in the areas they roam can benefit from wildlife, they will stand a better chance in a more inhospitable future.

Invasive ants get a warm welcome as global temperatures rise: Study
As people move plants, soil and goods around the world, insects including ants often hitch a ride, making themselves at home in new regions. A recent study finds that some of these nonnative ants, currently restricted to warmer indoor environments like buildings or greenhouses, could easily spread outdoors as global temperatures rise, raising concerns for […]
How rain can reveal what lives in rainforest treetops
Perched high above the forest floor, the tropical canopy is a reservoir of biodiversity that has long resisted scrutiny. Its inaccessibility has left many of its inhabitants — orchids, epiphytes, ants, monkeys, frogs — poorly studied and poorly protected. But a new study offers a workaround: let the rain do the climbing. Scientists led by […]
Respite, for now, for bird migration hotspot at heart of Sri Lanka’s wind power dispute
- Amid mounting protests from locals and environmentalists, Sri Lanka’s president has suspended a proposed wind farm in Mannar, in the island’s north for a month, pending a review of ecological concerns.
- Scientists warn additional wind farms in the area could further fragment habitats of the fragile Mannar Island ecosystem, an important stopover point for migratory birds on the Central Asian Flyway.
- The country’s energy minister has referred to Mannar as “stale land,” dismissing its biodiversity value, but environmentalists have countered this with research that shows more than 500 plant and animal species recorded there, including dozens found nowhere else on Earth.
- Activists urge the government to pursue sustainable development that protects Mannar’s globally important ecosystems while expanding clean energy following a balanced development pathway.

Belize project seeks out heat-resilient corals to protect its reefs
- An initiative called the Super Reefs program is setting out to identify the corals in Belize’s waters that have the highest chance of surviving warming waters amid climate change.
- Researchers with the program have discovered that corals that grow in the hottest areas are naturally more heat-resistant.
- Massive starlet coral (Siderastrea siderea) tends to be tolerant of warm water, whereas symmetrical brain coral (Pseudodiploria strigosa) is more sensitive.
- The team plans to use its findings, which are to be published by 2026, to inform the Belize government which coral communities in the country are best suited for protection and restoration.

Whale shark hotspot discovered along the Great Barrier Reef
- Whale sharks (Rhincodon typus) are the largest fish in the world and are endangered but are hard to study because they’re largely solitary creatures that roam great distances.
- There are only about 30 sites worldwide where they’re known to aggregate — and scientists have finally identified one of them along the Great Barrier Reef, a new study reveals.
- It’s the first known aggregation found in eastern Australia and in the entire southwest Pacific Ocean.
- The finding is significant for whale shark research and conservation efforts, experts said.

Are crows really street smart? Science confirms the genius of corvids (commentary)
- Crows and other corvids exhibit remarkable intelligence — including tool use, problem-solving, memory and even social awareness — challenging long-held assumptions that such cognitive abilities are exclusive to humans or primates.
- Scientific research and experiments, some inspired by popular fables about clever crows, show that these birds understand cause and effect, plan for the future, and adapt their behavior based on context, environment and who’s watching.
- Urban crows thrive due to cognitive flexibility, as shown in an ongoing experimental project in India, which highlights their strategic foraging, memory and ability to learn and adapt in human-dominated environments.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

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.

As climate change burdens grow, community mental health alarm bells ring
- People worldwide are struggling emotionally with the relentless escalation of the climate crisis, and reports show that climate change-related threats to mental health and well-being are increasing. But this story goes beyond statistics to look at the impacts on communities, families and individuals in the developing world.
- Stories presented here tell of anxiety, depression, anger and sadness in the face of large-scale changes to communities and personal lives, mostly due to factors out of people’s hands, which leave them feeling powerless. The problem is especially acute in poorer vulnerable communities lacking sufficient mental health services.
- The current global capacity to deal with a climate change-induced mental health emergency is inadequate, say experts who are calling for the prioritization of mental health support as an integral part of climate change interventions and mitigation.
- Some local stories offer hope. Examples show how caring, engaged communities and individuals, plus government support, can help create resilience and hope. Coping strategies include culturally sensitive interventions, mentorship, ongoing mental health assistance and honest recognition of humanity’s climate change plight.

In India, humans & leopards meet near major cities; preserving habitat is crucial
- Bannerghatta National Park (BNP) sits on the edge of Bengaluru, one of India’s largest cities, putting humans and wildlife — such as leopards — in close proximity.
- A recent study estimates 80-85 leopards live in and around BNP, surpassing the leopard count around Mumbai, previously named as the city with the most leopards.
- The study recommends community outreach to increase awareness and acceptance of leopards as well as protecting key habitats in the area.
- Local residents who are accustomed to living among leopards share their stories of leopard interactions, noting their presence as “normal” and not “scary.”

A critical stopover for shorebirds awaits protection in Malaysia
- Malaysia’s Teluk Air Tawar-Kuala Muda (TAT-KM) mudflats host tens of thousands of migratory birds along the East Asian-Australasian Flyway, including at one point the critically endangered spoon-billed sandpiper, yet remain outside formal protection despite global population declines from habitat loss.
- A recent study found only 15% of the sandpiper’s suitable non-breeding habitat is protected, with threats from coastal reclamation, invasive plants and sea-level rise; scientists call for prioritizing high-threat wintering areas, especially in Thailand and Myanmar.
- Malaysian authorities plan to nominate TAT-KM as an East Asian-Australasian Flyway Partnership (EAAFP) site, which would be a first for Peninsular Malaysia, but the process requires local stakeholder support and faces lingering concerns over past proposals for aquaculture development in the area.
- Local fishers, NGOs and conservation groups are raising awareness, restoring habitats and promoting bird-watching to safeguard TAT-KM, amid fears that without formal recognition, development pressures could threaten the ecosystem’s integrity.

Cockatoos have at least 30 impressive dance moves: Study

Cockatoos are a family of parrots, which are highly intelligent birds. Many […]
Eswatini’s young honey-hunters sustain a rare bond with wild birds
In Eswatini, the Southern African country formerly known as Swaziland, people still commonly hunt for honey with the help of wild birds, a new study finds. This rare form of human-wildlife cooperation, which has disappeared from much of Africa, is expected to endure in Eswatini, sustained by tradition and peer-to-peer learning, researchers say. Only in […]
Study maps rare Borneo forests with unique habitats & urgent need for protection
- A new study has mapped lowland heath forests (kerangas) in Indonesian Borneo, revealing major changes in their extent and limited formal protection.
- In Central Kalimantan’s Rungan-Kahayan landscape, researchers documented unique habitats rich in biodiversity but surrounded by competing land uses.
- They noted that these forests are often overlooked due to misconceptions about their soils, despite their ecological and cultural importance.
- The study calls for urgent action to better understand, protect and sustainably manage these rare ecosystems.

With nocturnal surveys and awareness building, Sri Lanka steps up to protect its owls
- In Sri Lanka, volunteers and researchers survey owls at night along set routes to mark the International Owl Day that falls on Aug. 4. But what takes more effort is the public educational events to challenge deep-rooted superstitions about owls.
- From the common Indian scops owl (Otus bakkamoena) and brown hawk-owl (Ninox scutulata) to the elusive barn owl (Tyto alba), several owl species persist in Sri Lanka’s commercial capital city despite habitat loss and disturbance.
- In Sri Lankan culture, owls are generally viewed as a bad omen, leading to persecution and eviction from nesting sites, even though species like barn owls provide valuable rodent control, hence being particularly useful in urban settings.
- Practices such as placing hollow coconut trunks in agricultural fields to attract barn owls for natural pest control offer nature-based solutions that could be reintroduced to modern agriculture and beat the stigma around the species.

Wolves’ continued spread in California brings joy, controversy & conflicts
- After nearly a century’s absence, gray wolves continue to recolonize California, bringing changes and challenges to the state and its inhabitants.
- Ongoing research and monitoring programs are helping scientists understand growing wolf populations and their impact on prey species, other predators and alterations to the landscape.
- Gray wolves in California are protected under both federal and state laws. But balancing conservation, livestock predation and public safety concerns is complicated.
- The state has formulated a management plan for wolves: a compensation program for ranchers who lose livestock to wolves and efforts to mitigate conflicts.

What we can learn from the Nuer people and their sacred birds
For the pastoralist Nuer people who migrate with the seasons between western Ethiopia’s Gambella region and Africa’s largest wetland, the Sudd, in South Sudan, birds are gaatkuoth or “sacred children of God.” The community has identified at least 71 bird species that are culturally important to them and useful in traditional medicine, as well as […]
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: […]
Upmarket fish maw trade in Singapore & Malaysia includes endangered species: Study
- A new study using DNA barcoding reveals that Singapore and Malaysia’s fish maw markets include species listed as vulnerable, endangered or critically endangered, many of which are poorly monitored and sourced from unmanaged fisheries.
- Researchers identified 39 species from 503 dried maw samples, including critically endangered large yellow croakers and European eels, highlighting the scale and complexity of this high value, underregulated trade.
- Experts warn that the trade poses a growing threat to marine biodiversity, and with nearly 30% of samples coming from species lacking IUCN assessments, it makes sustainability difficult to evaluate.
- Researchers and conservationists urge governments to expand CITES protections, enhance species monitoring, educate stakeholders, and improve international coordination to prevent more marine species from being pushed toward extinction.

Ethiopia’s iconic Walia ibex faces extinction once again
The Walia ibex, an iconic wild goat species found only on the steep, ragged cliffs of the Simien Mountains in northern Ethiopia, has sharply declined in number over the past decade, according to a recent study. This puts the Walia ibex (Capra walie), now largely confined to Simien Mountains National Park, a UNESCO World Heritage […]
Study links long-term exposure to air pollution with increased dementia risk
More than a year of exposure to certain air pollutants is associated with an increased risk of dementia, according to a recently published study. Dementia, a group of diseases including Alzheimer’s, results in the loss of memory and a decline in cognitive abilities like thinking, reasoning and language skills. In 2019, dementia was estimated to […]
DNA research changes the fate of the most trafficked parrots in Colombia
- Colombian law demands that, after rehabilitation, trafficked wildlife must be released in their original home range. But that is often difficult to determine.
- Researchers sequenced the DNA of Colombia’s six Amazona parrot species, building a genetic database to help identify trafficked birds.
- With this tool, Colombian authorities will be able to compare the DNA of the rescued birds to trace their heritage and release them into their home habitat.
- This will prevent “unscientific” release of these birds, which could affect their survival, the ecosystem and the species’ evolutionary processes.

Indigenous leadership and science revive Panama’s degraded lands

However, these prized edible mushrooms have gained popularity throughout North America, where they’re spreading across forests and displacing native fungal species, a recent study has found. Aishwarya Veerabahu, lead author and a doctoral student at the University of Wisconsin-Madison, […]
The sacred humans-bird connection in Ethiopia’s wetlands: Interview with Abebayehu Aticho
- The Gambella region of Ethiopia is home to 71 bird species that are culturally important to the traditional pastoralist Nuer people and have several uses for the community, such as indicating seasonal changes and fish abundance.
- According to a recent study, the Nuer people maintain deep connections with these species, which helps the birds’ conservation, but threats to their habitats and wetlands are increasing.
- In the lead up to the Ramsar Convention on Wetlands (COP15), Mongabay interviewed the study’s lead author Abebayehu Aticho about the spiritual ties, symbiotic relationships of Nuer people with birds and wetlands, and strategies required for the species’ conservation.
- The preservation of traditional knowledge and its incorporation into conservation strategies and policy making at local, national and global levels is important, says Aticho.

Where there’s political will, there’s a way to stop tropical deforestation, study finds
- A study focused on why deforestation rates have slowed in Indonesia and the Brazilian Amazon revealed that political will was a critical factor, often as a result of pressure from civil society and diplomacy to conserve forests.
- The authors surveyed the expert opinions of researchers, policymakers and advocates working on forest conservation in Brazil or Indonesia.
- In Brazil, experts said government action — like satellite monitoring and recognizing Indigenous lands — was key to stopping deforestation.
- Indonesia’s forest conservation success comes not just from political will, but also from corporate efforts and pressure from civil society groups.

Saving polar bears and beluga whales: Interview with Alysa McCall
- Beluga Cam is a long-running initiative that aims to document the migration of almost 57,000 beluga whales through Hudson Bay in Canada.
- The project is run by the nonprofit Polar Bears International in a bid to collect more data about beluga migration as well as to create more awareness about the species.
- The initiative got an upgrade this year with a new boat that houses the cameras and other equipment deployed for the work.
- As the Arctic rapidly loses sea ice, species such as beluga whales and polar bears bear the brunt in terms of losing access to food and their habitats.

Study highlights dangers of declaring conservation success too soon
The IUCN Red List has long been the globally recognized gauge for assessing how close to extinction a given species is. An improvement in the species’ conservation status from a higher to a lower threat category, known as downlisting, can signal conservation success. But a recent study says this must be done cautiously to avoid […]
Commercial space race comes with multiple planetary health risks
- Space may be the final frontier, but the modern race to launch rockets and satellites at an unsurpassed rate has generated a large and rapidly growing environmental footprint, the full effects of which are poorly understood.
- Multiple companies and countries are rapidly increasing their launch capacity, with plans in the works to deploy tens of thousands of satellites within a few years. Experts warn this exponential increase brings with it major environmental concerns, from the ground to the upper atmosphere and into Earth orbit.
- Pollutants resulting from many thousands of rocket launches and from satellites burning up in the atmosphere could adversely impact the ozone layer and are already adding to climate change, but research is greatly lacking.
- Some experts warn of the Kessler Syndrome, a cascade of colliding and fragmenting space debris that may one day render key Earth orbits unusable. Analysts say proactive national and international regulations are needed to address multifaceted environmental impacts of a rapidly evolving space industry.

How much does it cost to restore a mangrove forest?
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. Mangroves, the amphibious forests that fringe tropical and subtropical coastlines, are ecological powerhouses. They buffer communities against storm surges, support fisheries, and sequester carbon at rates that rival their terrestrial counterparts. Yet despite growing recognition of their value, […]
In rare triumph, camera traps snap endangered wildcats in Pakistan
- Conservationists in Pakistan have snapped incredibly rare images of two small cat species: the Asiatic caracal (Caracal caracal schmitzi) and the sand cat (Felis margarita).
- The 2025 caracal image comes after two other sightings in the country were captured on camera phones.
- Very little is known about caracal and sand cat populations in the country. Though both species are of least concern at the global level, they’re highly endangered in Pakistan.
- Conservationists say they’re hopeful these sightings will spur interest in small cat species in Pakistan and encourage greater protection and targeted conservation measures.

Community patrols can slash environmental crime by 80% (commentary)
- When communities are equipped with training, resources and institutional support, they can become powerful guardians of biodiversity, the lead author of a new study writes.
- His team’s research showed that community-led patrols reduced illegal activities such as unregulated fishing, hunting and logging by up to 80% in two vast protected areas in the Brazilian Amazon, even in the near-total absence of formal government enforcement.
- “The implications of the study stretch beyond the Amazon. As funding and political support for environmental enforcement dwindle in many tropical countries, decentralized and community-driven strategies offer a practical path forward,” he argues.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Darkest-ever dwarfgoby fish gets named after Darth Vader
From the volcanic fjords of Tufi in Papua New Guinea, researchers have described a new-to-science species of a coral reef fish called a dwarfgoby with an unusual purplish-black color. The tiny fish is the “darkest of all described dwarfgobies,” the researchers say in the study, naming it Eviota vader after the Star Wars villain Darth […]
Conservation’s silent strain: Nature’s protectors face a mental health crisis
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. Amid the calls of gibbons and the whir of drones scanning forest canopies, a quieter crisis is unfolding within the ranks of those trying to save nature. Conservationists, often seen as tireless stewards of the planet’s dwindling biodiversity, […]
Evolution in overdrive as Baltic cod shrink due to fishing pressure, study shows
- The eastern Baltic cod has shrunk dramatically in size in recent decades due to rapid evolution — changes at the genetic level — caused by decades of intensive fishing, a new study says.
- Eastern Baltic cod, which are a distinct subpopulation of Atlantic cod (Gadus morhua), lost nearly half of their length and four-fifths of their weight from 1996 until 2019.
- It’s one of the first studies to show that a marine species has evolved in response to fishing pressure.
- An expert said the shrinking of the cod was “alarming,” and called on fisheries managers to work to protect fish biomass and size, given this new evidence of fisheries-induced evolution.

Small Australian carnivorous marsupial reclassified as 3 species: Study
Researchers describe the kultarr as “Australia’s cutest mammal”: It’s eyes are quite large for its mouse-like head, it’s ears are perky and it has long, thin legs that allow it to run so fast that it looks like it’s hopping. A recent study has now confirmed that the insect-eating marsupial is not one, but three […]
Sri Lanka’s plant messiah spreads optimism for biodiversity & conservation
- A young Sri Lankan scientist, Himesh Jayasinghe, has rediscovered more than 100 of 177 possibly extinct species in Sri Lanka as well as three of five extinct species and both species previously considered extinct in the wild.
- Jayasinghe up to now has found some 210 species that have never before been reported from Sri Lanka, with about 50 of them already known from India, while a further 20, though named in the historical literature, can now be added to the national floral inventory of Sri Lanka supported by hard evidence.
- These discoveries hint that unexpectedly high numbers of new plant species may await discovery even in well-explored tropical countries such as Sri Lanka and emphasizes that the process of inventorying biodiversity should not be retarded by the demands of formal taxonomy and informal names backed by georeferenced voucher specimens and photographs being sufficient for conservation purposes.
- Many species thought to be extinct may be rediscovered when targeted searches are conducted using new eyes, experts say.

Study finds two-thirds of India’s snow leopards are in Ladakh region
Snow leopards are often called “ghosts of the mountains,” and for good reason: They’re notoriously difficult to spot. But researchers behind a recent study used a comprehensive set of methods — from following the cats’ tracks and droppings, to deploying camera traps over vast areas — to find that the region of Ladakh in the […]
Deforestation in the Philippines may have caused infertile hybrids of endemic frogs, study finds
- The truncate-toed chorus frog is a widely distributed species in the Philippines archipelago, with four distinct subspecies. One of them, the Leyte chorus frog, first described around 80 years ago, is considered a rare, enigmatic and morphologically distinct subspecies that has not been seen for nearly half a century since its first sighting.
- In a recent study, scientists used genetic analysis to find that the subspecies is, in fact, a hybrid between another subspecies of the truncate-toed chorus frog and a ground-dwelling, closely related slender-digit chorus frog.
- Researchers say this infertile hybrid is a result of large-scale deforestation in the Philippines, which forced tree-dwelling frogs to come on land, where ground-dwelling frogs “ambushed” and mated with them, creating the hybrid.
- Conservationists say this hybrid shows how human-caused disturbances impact biodiversity in the Philippines, where deforestation is rampant due to mining, logging and expanding agriculture.

Global tracking study reveals marine megafauna hotspots lie largely unprotected
- A global study tracking nearly 13,000 marine animals representing 111 species reveals they spend 80% of their time in just 63% of their range, yet only about 5% of these high-use ocean areas are currently protected.
- The research identifies Important Marine Megafauna Areas (IMMegAs) as ecological hotspots that span national waters and the high seas, where governance and protection are often lacking.
- Findings show that the global target of protecting 30% of the ocean by 2030 is insufficient to safeguard migratory species unless paired with additional mitigation measures outside protected areas, like bycatch reduction and ship speed regulations.
- Researchers call for stronger international coordination and more dynamic, movement-informed conservation strategies to effectively protect wide-ranging ocean wildlife.

Bicolored waterberry: The overlooked tree shaping Zambia’s rivers
- The bicolored waterberry (Syzygium guineense subsp. barotsense) is a dominant tree along the Kafue and other major Zambian rivers, where it plays a vital structural and ecological role.
- Though capable of self-pollination, the tree’s flowers attract bees, birds and moths, creating vibrant micro-ecosystems in its canopy.
- While not currently threatened, riparian clearing poses local risks, and the trees’ value to pollinators may offer a path to conservation.

Tropical forest roots show strain as changes aboveground filter below
- Tropical forest plant roots have not received as much research attention as aboveground vegetation. This knowledge gap affects our understanding of how rainforests adapt to change, including their ability to capture and store atmospheric carbon.
- An emerging field of research is looking at how root systems respond to global change. New evidence dramatically underlines the outsized importance of tropical forests in the global carbon cycle. Tropical forests represent one of the world’s largest carbon sinks, largely thanks to plant roots, which add carbon to soils.
- Despite the challenge of studying tiny roots hidden underground, researchers are uncovering important insights. Some tropical forests send roots deeper into the soil under dry conditions, possibly seeking moisture, which may aid in drought tolerance. Others seem unable to do this, making them more vulnerable to climate change.
- Recent plant root studies are confirming the immense stress tropical rainforests are under, with conditions changing faster than roots belowground can adapt. Knowing more precisely which forests can, and can’t, tolerate escalating climate change and other stressors could better inform management and conservation decisions.

River of giants: Canoe team tracks hippos in one of Africa’s last strongholds
- A team from The Wilderness Project has conducted a survey of hippos along Zambia’s Kafue River, one of the last strongholds of the species in Southern Africa.
- The expedition faced regular close encounters with hippos, which are highly territorial and can be dangerous to people, especially when traveling by boat.
- The team counted nearly 2,400 hippos, most of them along a 350-kilometer (217-mile) stretch of the Kafue within the Kafue National Park and adjoining protected areas, underscoring the park’s conservation importance.
- Despite their ecological significance as ecosystem engineers, hippos remain understudied and increasingly vulnerable to habitat loss and pollution, including upstream mining spills.

Wildlife & tourists on the up in Zambia’s Kafue Park: Q&A with manager Craig Reid
- Zambia’s Kafue National Park, co-managed by Zambia’s Department of National Parks and Wildlife and conservation NGO African Parks, is home to up to 22 different species of antelopes, the highest diversity in Africa, more than 500 species of birds and at least 2,400 hippos in the river from which the park takes its name.
- Park manager Craig Reid says the nine game management areas that provide a buffer zone around the park have been modified in one way or another — including by climate-affected farmers and livestock herders — and illegal hunting also poses a threat to the core zone’s ecological integrity, as does pollution from mining and large settlements upstream.
- But, he says, around 3 million hectares (7.4 million acres) of the GMA buffer remains completely unsettled, and the park and the stretch of the Kafue that runs through it are doing well – more than $4 million worth of fish is sustainably caught within its boundaries every year.
- African Parks plans to introduce as many as 60 black rhinos to Kafue NP in the coming years and has already reestablished a thriving population of Kafue lechwe, a wetlands antelope unique to this landscape.

‘Revolutionary technology’ uses scanners for easier species detection in the wild
Researchers in Brazil’s Amazonas state are testing easy-to-use scanners that can help them identify animal species they come across in the wild, Mongabay contributor Miguel Monteiro reported in June. The scanners use a technology called near-infrared spectroscopy (NIRS), which currently has many applications, from measuring food quality to monitoring blood oxygen levels in the medical […]
Scientists turn plastic waste into pain medicine
Researchers have devised a way to make a commonly used pain and fever reduction medication from plastic waste. Yes, you read that right. They used genetically engineered microbes to transform a molecule obtained from polyethylene terephthalate (PET) plastic into paracetamol. Also known as acetaminophen, paracetamol is the active ingredient in widely available over-the-counter pain and […]
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.

‘Croc on a rock’: How a group of explorers suffers for science
- A team from The Wilderness Project is traversing Zambia’s Kafue River by canoe, collecting ecological data as part of a long-term survey.
- The expedition involves grueling portages over sharp, slippery rocks, close encounters with crocodiles and hippos and physically demanding conditions.
- Researchers gather DNA from fish and invasive crayfish, record nocturnal wildlife sounds and retrace a sampling transect first surveyed the year before.
- Despite the challenges, moments of beauty and wildlife encounters — from elephant herds to misty hornbill flights — punctuate the journey.

A success story at Zambia’s leopard hotspot: Interview with ecologist Chisomo M’hango
- At the Musekese Conservation research station, deep in Zambia’s Kafue National Park, trainee field ecologist Chisomo M’hango analyzes camera trap images of leopards, lions and wild dogs.
- M’hango and colleagues have identified 95 individual leopards, one of the highest densities of this vulnerable species anywhere in Southern Africa.
- The camera traps have caught relatively few lions, likely due to lack of prey in an area where widespread hunting of large antelopes has taken place for decades; M’hango says lion numbers are starting to rise, signaling renewed efforts to prevent poaching in the park and its buffer areas is bearing fruit.
- There are also encouraging signs that populations of wild dogs are recovering, with the single pair monitored soon after Musekese’s research began in 2020 multiplying into three healthy packs of this gregarious endangered carnivore.

In theory, they could provide more than a third of the climate […]
From cattle to crayfish, human pressures mount on Zambia’s Kafue River
- A group of scientists paddled the length of Zambia’s Kafue River to document ecological pressures, including invasive species, habitat changes and human encroachment.
- Australian red-clawed crayfish (Cherax quadricarinatus) have infested the river, outcompeting native species, disrupting fisheries and altering fishing practices. The crayfish invasion spans nearly the entire 1,600-kilometer (995-mile) river, traced to an original introduction in 2001.
- Overgrazing and invasive plants like the giant sensitive bush are transforming some riparian zones, threatening biodiversity, including endemic species like the Kafue lechwe (Kobus leche kafuensis).
- Researchers with The Wilderness Project’s Great Spine of Africa project are using standardized field methods to monitor river health and the spread of invasive species to inform future conservation efforts.

Energy transition boom drives rise in lawsuits against alleged rights abuses
A new analysis has found that lawsuits against transition mineral mining firms and renewable energy companies are increasing worldwide. The NGO Business & Human Rights Resource Centre (BHRRC) in its new report published July 1 notes that since 2009, its transition litigation tracking tool has documented 95 legal cases filed against companies linked to the […]
Endangered Andean cat is imperiled by climate change and its solutions
- The Andean cat is an endangered and elusive wildcat species found in the high Andes Mountain regions of Argentina, Bolivia, Chile and Peru.
- The species is exceedingly rare across its entire range and researchers must endure high altitudes, reduced oxygen levels and adverse weather conditions to study and monitor widely scattered populations.
- Climate change and our attempts to curb it both put this small cat at risk. As the world warms, the Andean cat’s cold mountain habitat shrinks ever smaller. Global warming is also driving up demand for lithium and other rare metals for electric vehicles, with extractive industries pushing ever deeper into alpine zones.
- With low numbers and low density, addressing local threats is vital to protecting felid populations, making every single Andean cat important for species survival, researchers say. Innovative local community programs have contributed to conserving this small Latin American cat.

Mining spill highlights need to protect Zambia’s vital Kafue River & its fish
- Researchers from The Wilderness Project (TWP) are documenting fish diversity along Zambia’s Kafue River to build a DNA reference library.
- The TWP scientists are collecting fin clippings and environmental DNA to help identify species, including some potentially new to science, without needing to catch them in the future.
- The river, a vital source of food and income for local communities, suffered from major pollution in February when a mine waste dam failed upstream.
- Protected stretches of the river within Kafue National Park offer crucial refuge for fish and other aquatic life, enabling recolonization after environmental shocks like toxic spills.

Community patrolling reduces crime numbers in the Amazon, study shows
A study conducted in the Brazilian Amazon has found that community-based volunteer patrolling efforts in two protected areas were associated with an 80% reduction in recorded environmental crimes from 2003-13. During the same period, there was no clear decline in environmental violations detected by government-led operations outside those protected areas, suggesting that community-based patrols were […]
Out-of-range albatross makes a highlight in the revival of seabird watching in Sri Lanka
- Sri Lanka has recorded over 50 species of seabirds — birds that spend much of their lives at sea — within its territorial waters, including several long-distance migratory birds that travel thousands of kilometers across oceans.
- As observation of seabirds is challenging, only a small group of Sri Lankan birders have focused on this unique group. In the past decade, seabird studies in the island have seen a notable revival, led by enthusiastic young birders.
- Among last year’s remarkable observations is the sighting of a grey-headed albatross off Sri Lanka’s northern coast, marking the first-ever record of the species north of the equator, well beyond its usual Southern Ocean range near Antarctica.
- World Seabird Day, observed every year on July 3, commemorates the tragic extinction of the great auk, marking the last known pair of which was killed on that day in 1844 and highlighting the vulnerability of seabirds and the urgent need for their conservation.

Forest connectivity key to preserving PNG’s spectacular rainforest birds: Study
- Papua New Guinea is a global hotspot of avian biodiversity, home to spectacular and behaviorally complex bird species that occur nowhere else on the planet.
- A new study shows that forest fragmentation reduces unique forest-specialist birds, but boosts generalist species like pigeons, sunbirds and bulbuls.
- Birds suffered greater declines in habitats cut off from the surrounding landscape, compared to degraded habitats that remained connected to nearby intact forests.
- The shift in the bird community in degraded and isolated habitats undermines ecosystem stability and resilience, as birds that once performed vital pollination, seed dispersal and insect control services are lost.

Young secondary forests may be the planet’s most overlooked carbon sink
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. As governments and corporations scramble to meet climate pledges, the search for reliable and scalable carbon removal strategies has turned increasingly toward forests. But while tree planting captures the public imagination, a new study suggests a simpler, less […]
In Latin America, energy transition stirs a rise in human rights lawsuits
- A new report from the Business & Human Rights Resource Centre (BHRRC) finds that more than half of the 95 energy transition-related lawsuits recorded globally since 2009 took place in Latin America and the Caribbean.
- Almost half of all cases were filed by Indigenous peoples; 70% of cases globally and 76% of those filed in Latin America and the Caribbean concerned mining for transition minerals.
- The report urges governments, companies and investors to conduct robust human and environmental due diligence across the entire renewable energy value chain and to adopt a human rights-centered approach throughout project life cycles.

Traditional hunting shifts with access to cheap guns in India’s Nagaland: Study
Among Indigenous Naga tribes in India’s northeastern state of Nagaland, hunting traditions are transforming as cheap homemade guns make targeting commercially valuable large mammals easier, a recent study finds. “Indigenous hunting preferences are rooted in cultural traditions but have evolved under the influence of economic pressures and environmental changes,” Satem Longchar, conservation ecologist and the […]
Study urges legal protection for Sulawesi’s endangered bear cuscus amid habitat loss
- A new study has revealed that the endangered bear cuscus in South Sulawesi occupies a highly fragmented and shrinking habitat, with less than 1% of surveyed areas deemed suitable, largely due to poaching, mining expansion and forest loss.
- Despite being previously protected, the species was excluded from Indonesia’s 2018 protected species list, and researchers argue this oversight must be corrected given the animal’s vulnerability and ecological importance.
- The study also highlights the cuscus’ broader scientific significance as one of the few marsupials in western Wallacea, as well as its cultural and emotional value to local communities that have learned to coexist with it.
- Experts and the study’s authors urge stronger habitat protection, stricter environmental controls and greater public engagement to ensure the species’ survival.

As Thailand’s fishing cats face habitat loss & conflict, experts seek resolution
- Fishing cats have lost vast swathes of their former range in Thailand, where decades of wetland conversion to fish farms, shrimp ponds and plantations have decimated their numbers.
- With habitats shrinking, these wild cats have been driven to living in human-dominated landscapes, where conflicts often arise.
- Fishing cats perceived as competing with farmers for fish and chickens are sometimes killed in retaliation.
- Activists and NGOs are working to reduce these conflicts and encourage landowners to preserve patches of remaining habitat suitable for the cats.

Assisted colonization could be our ally in adapting to climate change, study suggests
- As climate change rapidly transforms ecosystems, it threatens to wipe out vital species, potentially leading to ecosystem collapse.
- Islands, to which many species from elsewhere can’t disperse naturally, are particularly vulnerable to these threats.
- In a recent study, scientists argue that assisted colonization, where species from neighboring regions are introduced to better cope with the changing climate, could help the forests of Great Britain adapt to the rapidly changing climate.
- Some conservationists say that assisted colonization is a proactive way of thinking about conservation in a changing world, rather than more reactive approaches such as species reintroductions.

Forest corridors protect Colombia’s critically endangered brown spider monkey
- Brown spider monkeys (Ateles hybridus) are some of the world’s most threatened primates, as deforestation has razed about 85% of their habitat in Colombia.
- With monkey populations living in patches of forests, conservationists in the Middle Magdalena region feared that low genetic variation could lead to a further collapse of the species, so they started creating biological corridors connecting forest fragments.
- The project currently maintains 15 ecological corridors, with plans to create six more. Researchers work with landowners to create private conservation areas, leveraging the benefits of forest restoration for agriculture and ecosystems in general.

Bogong moths use stars and the Milky Way to make epic migration
In Australia, millions of newly hatched Bogong moths embark on an impressive journey twice a year. Each spring, they hatch from eggs in their breeding grounds in Australia’s southeast and fly up to 1,000 kilometers (621 miles) further southward to spend a few months in the cool caves of the Australian Alps — a place […]
Communities and ecosystems in Venezuela learn to adapt to life after glaciers
- In 2023, La Corona, Venezuela’s last standing glacier in the Sierra Nevada de Mérida National Park, was reclassified as an ice field, having shrunk to the size of barely two football fields.
- The country is now the first tropical nation to lose all of its glaciers, which melted rapidly due to a combination of warming temperatures, reduced rainfall and ineffective policies since early signs of melting appeared in the late 19th century.
- As Venezuela’s symbolic glaciers began melting one after another, a team of researchers started studying not only their disappearance, but the emerging ecosystems that were taking over the formerly icy areas.
- With the ice gone, the city of Mérida, advertised for decades as the “city of eternal snow,” is now having to reinvent its identity and its tourism industry.

First-ever assessment highlights threats to Atlantic cold-water corals
- A new study published in the journal Marine Biodiversity delivers the first global IUCN Red List assessments for 22 cold-water coral species in the Northeast Atlantic.
- More than 30% of the species are at risk of extinction due to bottom-contact fishing, habitat destruction and climate change, with white coral (Desmophyllum pertusum) listed as globally vulnerable.
- Experts say the findings highlight gaps in conservation, especially for deep-sea species often excluded from monitoring and protection efforts.
- The study’s release comes at a key moment, as international talks continue under the Beyond National Jurisdiction Treaty to improve high seas biodiversity protections.

As ocean acidification ramps up, experts call for speedy ocean protection
- Scientists have known for decades that soaring atmospheric carbon dioxide emissions are causing changes in ocean chemistry, threatening marine life and ecosystems.
- In June 2025, a study found that ocean acidification has passed a safe threshold across large swathes of the world’s marine environment, not only near the sea surface, but also up to 200 meters (656 feet) deep. The effect is especially severe in polar regions.
- Ocean acidification is an added stressor to marine life already facing pressure from multiple threats connected to climate change (including marine heatwaves and reduced oxygen levels in seawater), along with other direct human impacts including pollution, overfishing and deep-sea mining.
- Carbon emissions need to be deeply slashed and ocean protections greatly enhanced to allow ecosystems time to adapt and one day recover, say experts.

‘Forgotten’ leopards being driven to silent extinction by poaching and trade
- Leopards are the second-most traded wildcat in the world, despite their international commercial trade being prohibited under CITES, the international wildlife trade agreement.
- Trophies and body parts — primarily skins, claws, bones and teeth — are the most traded, according to CITES data. However, other data indicate that illegal trade in skins and body parts is widespread in Asia and Africa.
- Southern African countries, particularly South Africa, Namibia and Zimbabwe, are major exporters of leopard parts, while the U.S. is the largest importer, according to data from CITES. But China remains a hotspot for trafficked leopard parts, including skin and claws.
- The legal and illegal trade, coupled with losses to habitat and prey, has caused widespread declines in leopard populations across their ranges in Asia and Africa.

Vanishing giants: The Indian Ocean’s biggest fish need saving (commentary)
- New research confirms the decline of predatory and large-bodied fishes in the western Indian Ocean due to overfishing, unregulated fishing practices and climate change.
- The lead author of a new paper published in the journal Conservation Biology argues that these fish must be protected to ensure healthier reefs, marine ecosystems and adjacent human communities.
- “This issue isn’t just about protecting fish, but also maintaining a healthy ecosystem, supporting a crucial food source for millions and sustaining the livelihoods of many coastal communities. If we act now, we can still turn the tide,” the author writes.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

DNA sequencing to meet global biodiversity goals: Interview with Tyler Kartzinel
- A new study has highlighted gaps in reference databases that are required by scientists for DNA sequencing, especially in tropical biodiversity hotspots around the world.
- DNA technology has advanced rapidly in recent years, but the lack of extensive reference databases makes species identification a challenge, especially in remote areas.
- The lead author of the study emphasizes the need to ramp up work to create these databases, especially as the world works toward critical goals to protect ecosystems and the biodiversity that lives in 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 […]
Checkout counter tech eases wildlife identification in the field
- Using spectroscopy, scientists can identify species during fieldwork, without the need for lengthy and costly analyses such as genetic testing or bioacoustics.
- Studies show a reliability rate of 80%, with practitioners looking to expand the reference database and provide information that’s crucial for monitoring biodiversity and combating the illegal wildlife trade, among other uses.
- Experts highlight the low cost and practicality of the equipment if improved methods are designed to create new solutions for conservation in areas with a wide variety of fauna, such as the Amazon.

On a Patagonian plateau, a microendemic frog makes a hopeful comeback
- Conservationists in Argentina’s Patagonia region have helped save the country’s most threatened amphibian, the El Rincon stream frog, a species whose entire existence centers on a single warm stream in the Somuncurá Plateau.
- To restore the frog population, researchers removed invasive trout from the stream, bred hundreds of frogs in captivity and released them in the wild, and worked with ranchers to keep cattle out of the frogs’ habitat.
- Researcher Federico Kacoliris, who mobilized the conservation movement around the species, recently received a Whitley Award, known as the “Green Oscars,” which will help his foundation expand protections in the area.

Whales still aren’t ‘eating all the fish’ (commentary)
- Estimating the amounts of krill or fish consumed by whales has long been an obsession of the proponents of industrial whaling, who argue that these amounts are too large and then use the figures as justification to hunt whales.
- However, this research is pseudoscience, a new op-ed argues, and badly misunderstands — or willingly misrepresents — established principles of marine ecology.
- “In order to counter the wild imaginings of how marine ecosystems work put forth by whalers and their bureaucratic enablers in whaling nations, new thinking is required,” the former NOAA scientist writes.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Another way to check the health of a coral reef: Study the microbes in the seawater
- An increasingly common way to keep tabs on coral reef health is by measuring microorganisms in the local seawater.
- Microbial-based coral reef monitoring is excellent at detecting nutrient and health changes on a reef and can draw attention to environmental disturbances; microbes are particularly good at sending such signals because they react quickly to pollution.
- This type of monitoring can help provide a fuller, faster and lower-cost picture of reef health than visual surveys alone, the most common current method.
- Two marine scientists explain the “why” and the “how” of microbial-based reef monitoring in a recent paper.

Wildfires push tropical forest loss in Latin America to record highs
- Recent data from the University of Maryland show the tropics lost 6.7 million hectares (16.6 million acres) of primary rainforest in 2024 — nearly double the loss of 2023 and the highest on record.
- Six Latin American countries were in the top 10 nations for primary tropical forest loss.
- In the Amazon, forest loss more than doubled from 2023 to 2024, with more than half the result of wildfires. Other key drivers include agricultural expansion and criminal networks that increasingly threaten the region through gold mining, drug trafficking and other illicit activities.
- Fire was the leading driver of forest loss (49.5%), destroying 2.84 million hectares (7 million acres) of forest cover in Brazil, Bolivia and Mexico alone.

To reduce rhino poaching — by a lot — cut off their horns, study says
Poaching has decimated rhino populations across Africa, but a new study finds that dehorning the animals, or surgically removing their horns, drastically reduces poaching. The study focused on 11 reserves in the Greater Kruger ecosystem that sprawls across the border of South Africa and Mozambique. Poachers killed nearly 2,000 rhinos here, 6.5% of the reserves’ […]
Protect one large forest, or many small ones? New study reignites conservation debate
- The scientific community has been divided since the 1970s as to which sort of forest offers more protection for biodiversity: a set of many small patches of forest, or a single large tract?
- A newly published study has rekindled the debate, backing the thesis that large expanses of green space are more important for species conservation, particularly for larger animals that require a more extensive range.
- The debate could help policymakers better direct conservation efforts and funding, but researchers agree that all standing forest, regardless of size, must be protected.

Unique notes in sarus crane duets help distinguish sexes for conservation
Sarus cranes typically live most of their lives as a male-female duo, singing tightly coordinated duets. At a glance, the male and female, both standing 1.5-1.8 meters (5-6 feet) tall, are difficult to tell apart visually. They’re both gray-bodied with red necks and head. But researchers have found a way of distinguishing between the sexes […]
Mounting risks due to climate change threaten Sri Lanka’s endemic species
- Sri Lanka’s isolation during past glacial cycles resulted in the evolution of unique species, but ongoing human-induced climate change now poses a major threat to their survival.
- Using species distribution models, researchers have discovered that montane amphibians and reptiles that are particularly restricted to narrow ecological niches with limited mobility are particularly vulnerable to rising temperatures.
- Species with direct development, like many Pseudophilautus frogs, which bypass the tadpole stage, are especially sensitive to microclimate changes.
- Of the 34 amphibian species confirmed extinct worldwide, 21 were endemic to Sri Lanka, underscoring the island’s fragility and the urgent need for targeted conservation efforts.

“The Birds,” Revisited (cartoon)
A new study using citizen science data via eBird — an app used by birdwatchers to record sightings — has found that declines in bird populations in North America are the steepest where the respective species have historically been most abundant.
Endangered shark trophies dominate the online wildlife trade, study finds
- A recent study analyzed wildlife product listings from 148 online marketplaces over a three-month period and identified more than 500 products from 83 threatened wildlife species, some of which were also listed on CITES Appendix I.
- Shark trophies — mainly jaws — dominated the listings, accounting for nearly two-thirds of the advertised products, and 73% of those came from endangered and critically endangered shark species.
- The study found 95% of animal products were sold on just four websites in 2018 and, since then, most of these companies have changed their policies to prohibit the trade of certain species. But researchers say it’s not enough.
- This study highlights the need to strengthen policies in regulating the online wildlife trade, spreading awareness and closing loopholes in legal trade, especially for species threatened with extinction.

Jaguar recovery unites Brazil and Argentina in conservation effort
- Once on the brink of local extinction, jaguar numbers across the Brazil-Argentina Iguaçu-Iguazú border have more than doubled since 2010 thanks to coordinated conservation efforts.
- The cross-border collaboration between groups in both countries has been crucial to restoring jaguar populations across the Atlantic Forest Green Corridor.
- Women-led economic initiatives and formal institutional support, like “Jaguar Friendly” certification for the local airport, are strengthening human-wildlife connections.
- The long-term survival of jaguars in Iguaçu-Iguazú, a population considered critically endangered, depends on political will and habitat connectivity, as the big cats remain isolated from other jaguar groups.

New study dismisses Amazon River runoff as primary cause of sargassum blooms
- Brazil’s northern beaches recently suffered from arrivals of sargassum blooms, a phenomenon affecting Caribbean nations that most scientists so far have associated with nutrients coming from the Amazon River plume into the Atlantic Ocean.
- A recent study suggests that ocean changes are the primary nutrient source for sargassum blooms since 2011, challenging previous hypotheses.
- Sargassum is causing considerable health and economic concerns as large amounts of this brown macroalgae arrive and accumulate in coastal ecosystems of western Africa and the greater Caribbean Sea every year.
- Brazilian authorities are learning from Caribbean countries how to manage sargassum blooms best, and experts think they should keep monitoring possible ocean current changes.

Penguin poop helps form clouds over Antarctica, potentially cooling it
In Antarctica, penguin poop, or guano, can cover the ground for miles, especially around penguin colonies with thousands of individuals. In fact, large, brown guano stains on Antarctica’s white ice have even helped scientists discover new penguin colonies from space. A recent study now finds that the massive amounts of guano play a critical role: […]
Gelada monkey vocalizations offer insight into human evolution: Study
With their bright red, hairless chests and grass-grazing lifestyle, gelada monkeys are quite unusual. They are the only primate, other than humans, to primarily live on land instead of in trees, and a new study shows they are also able to detect emotional and social cues through vocal exchanges. “Geladas are special because they live […]
New population of rare douc langurs found in Vietnam’s highland forests
- Conservationists surveying upland forests in central Vietnam have located a new subpopulation of critically endangered gray-shanked douc langurs.
- Fewer than 2,400 individuals are thought to remain in the wild, mostly in Vietnam, where more than half live outside of formally protected areas.
- Forest loss and hunting pressure have driven the species to the brink of extinction, spurring stakeholders to develop an action plan for the species in 2022.
- Experts say the new discovery underscores the need for conservation measures that go beyond traditional area-based approaches to encompass habitat restoration, community-based programs and habitat corridors.

New method can detect nearly every coral genus in Japan from water samples
- Environmental DNA (eDNA) coral research involves analyzing water samples to identify corals based on the DNA that they secrete into the water, largely via their mucus.
- eDNA research on corals can help scientists understand the changes wrought by global warming and marine pollution by providing coral identification data faster and in some cases more accurately than visual surveys by scientists.
- A team of marine scientists based in Japan, an archipelagic nation with a high level of coral biodiversity, has used an eDNA method to develop a system that can detect nearly all of the country’s 85 reef-building coral genera; no other research group in the world has achieved the same level of detection accuracy and coverage for corals using eDNA.
- They released their findings in a study published on May 22.

Clouded leopard seen preying on Bengal slow loris in rare photograph
In December 2024, a camera trap installed in Dehing Patkai National Park in northeast India’s Assam state captured a rare scene: a clouded leopard with a Bengal slow loris in its mouth. Both species are extremely elusive, so the photograph is rare confirmation that the medium-sized wildcat preys on the small, endangered primate, reports contributor […]

In recent years, we’re learning more about how fungi work, what they can do, and how they can help mitigate the climate crisis. They play a crucial role in balancing ecosystems, and keeping carbon out of the atmosphere. Innovative researchers are also investigating ways fungi can replace plastic, keep toxins out of our soils, and […]
Researchers identify 22 key areas for protecting struggling giant otters
- The giant otter (Pteronura brasiliensis) is an endangered species, according to the International Union for Conservation of Nature (IUCN).
- A recently published report authored by more than 50 researchers from 12 South American countries identifies and prioritizes 22 areas for giant otter conservation.
- The main threats to giant otters include habitat destruction, overfishing and pollution of water sources by agricultural and extractive industries.
- The results of the report will be shared with the 12 governments of the countries that encompass the species’ historical distribution.

Female bonobos wield power through unity: Study
Male bonobos are larger and stronger than females, so researchers have found it puzzling that the female apes enjoy high status in bonobo society. After analyzing three decades of behavioral data, researchers recently shared a study that pinpoints their source of power: female alliances and coalitions. “Only [among] bonobos, females form coalitions to gain power […]
Only a tiny % of the deep seafloor has ever been visually observed: Study
- Just 0.001% of the deep seafloor has ever been captured by photo or video images, a new study finds.
- That which has been captured is “biased” and potentially unrepresentative: 65% of observations have been in the waters of the United States, Japan or New Zealand, according to the study.
- Experts told Mongabay that policymakers at a wide range of international institutions should bear the study’s findings in mind, including those governing high seas fisheries, deep-sea mining, and the use of marine carbon dioxide sequestration systems.

Tabby’s likely ancestor & Earth’s most widespread wildcat is an enigma
- The Afro-Asiatic wildcat (Felis lybica) is the world’s most widely distributed small wildcat, but it’s also one of the least studied. The cat’s conservation status is listed as “of least concern” by the IUCN. But due to a lack of data, population trends are unknown, and the species, or subspecies, could vanish before humanity realizes it.
- One of the only long-term studies on the cat’s behavior and population genetics occurred in South Africa’s Kgalagadi Transfrontier Park. It sheds light on a species that is vital to the ecosystems it inhabits and possesses remarkable adaptability.
- At some point, thousands of years ago, F. lybica was domesticated, making it the ancestor of the common house cat (F. catus), which, in evolutionary terms, has become one of the most successful mammal species on Earth.
- Inbreeding with domestic cats has become a serious threat to Afro-Asiatic wildcat conservation. Wildcat experts urge pet owners to spay their house cats. Feral cats should also be spayed, especially in areas bordering preserves where F. lybica lives. Education about this small wildcat could also help with its conservation.

Tuna fishing devices drift through a third of oceans, harming corals, coasts: Study
- Drifting fish aggregating devices (dFADs) are floating rafts with underwater netting used by fishing vessels to attract tuna.
- A recent study estimated that between 2007 and 2021, 1.41 million dFADs drifted through 37% of the world’s oceans, stranding in 104 maritime jurisdictions and often polluting sensitive marine habitats.
- Strandings were most frequent in the Indian and Pacific oceans, with the Seychelles, Somalia and French Polynesia accounting for 43% of cases; ecosystem damage and cleanup costs fall on local communities.

‘Satellites for Biodiversity’ upgrades with new projects and launches insight hub
The Airbus Foundation and the Connected Conservation Foundation (CCF) recently announced the winners of their “Satellites for Biodiversity” grant, which now uses higher-resolution satellite imagery to aid conservation efforts. They also launched an Ecosystem Insight Hub, which comprehensively documents the processes and findings of their grantees. The latest batch of six “Satellites for Biodiversity” awardees […]
Coral reef research dominated by rich countries, plagued with inequities: Study
- A new study finds that coral reef researchers come mainly from institutions in high-income countries, and that the contributions of researchers from tropical, lower-income nations aren’t adequately recognized.
- “Parachute” research that leaves out local input is common, and when more local researchers are included, they report that it’s often done in a tokenistic way, the study finds.
- The lead authors say the same communities that face the most direct impacts from the demise of coral reefs are left out of the scientific study of reefs.

Sri Lanka’s golden jackals reveal importance of urban wetlands for wildlife
- Recent sightings of golden jackals (Canis aureus naria) in Sri Lanka’s capital city underscore the significance of urban wetlands as sanctuaries for wildlife amid rapid urbanization.
- The jackals in Sri Lanka belong to a distinct subspecies, Canis aureus naria, have recorded a sharp population decline due to multiple reasons ranging from habitat loss to roadkills and diseases transmitted by stray dogs.
- In the global context, golden jackals are expanding their range into Northern Europe, driven by many factors including climate and landscape changes.
- With growing global conservation interest, initiatives like World Jackal Day, observed on April 19, aim to raise awareness and foster scientific collaboration for the species’ protection.

DNA probe links Japan’s otter-themed cafes to poaching hotspots in Thailand
- Asian small-clawed otters have long been taken from their wild habitats in Southeast Asia to supply the opaque and often illegal pet trade.
- Booming demand for captive otters, stoked by social media and TV shows, looks set to worsen amid an emerging trend for exotic animals cafes.
- A new genetic study links otters found in exotic animal cafes in Japan with wild populations in well-known poaching hotspots in southern Thailand.
- The new DNA evidence of a wildlife trade route between Thailand and Japan backs up calls from experts for stricter monitoring of wildlife exports from Thailand, as well as strengthened law enforcement and education in known poaching hotspots.

Environmental defenders targeted in 3 out of 4 human rights attacks: Report
More than 6,400 attacks against human rights defenders were reported between 2015 to 2024, according to a new report from nonprofit Business & Human Rights Resource Centre (BHRRC). “That’s close to two attacks every day over the past 10 years against defenders who are raising concerns about business-related risks and harms,” said Christen Dobson, co-head […]
In Panama, an Indigenous-led project rewrites the rules of reforestation
- Scientists from the Smithsonian Tropical Research Institute are collaborating with local communities in the Ngäbe-Buglé Comarca, a protected Indigenous territory, to foster a ground-up reforestation strategy using native trees and carbon payments.
- The project involves about 30 plots totaling 100 hectares (247 acres) of land, giving participants full ownership of their trees.
- The approach is based on carbon-sequestration data and other scientific metrics collected from Smithsonian’s Agua Salud research site in Colón.
- The work also leans on economic analyses to ensure that reforestation projects can become reliable and sustainable livelihood strategies for Panama’s rural communities.

Brazil bets on macaúba palm to make renewable diesel and aviation biofuel
- Macaúba, a palm tree found across the Americas, is tipped as a new biofuel feedstock to decarbonize transport and aviation. The macaúba palm produces an oil when highly refined that can be made into renewable diesel and sustainable aviation fuel (SAF).
- Bolstered by hype and billions of dollars of investment, companies are planning to plant hundreds of thousands of hectares on reportedly degraded land across Brazil. Firms are also investing in major refining facilities. This macaúba gold rush was triggered by major financial incentives from the Brazilian government.
- Macaúba’s potential green attributes are similar to jatropha, a once promising biofuel feedstock that bombed a decade ago. Macaúba is widespread but currently undomesticated. Whether macaúba plantations can achieve the yield and scale needed to help satisfy the world’s sustainable energy needs remains unknown.
- Industry proponents state that it can be produced sustainably with no land-use change or deforestation. But other analysts say that very much depends on how the coming boom, in Brazil and elsewhere, pans out.

Why biological diversity should be at the heart of conservation
For the last several decades, global biodiversity has been in crisis. Yet, as we celebrate International Day for Biodiversity on May 22, which commemorates the adoption of the Convention on Biological Diversity, a global treaty, we offer some recent Mongabay stories highlighting lessons from undoing past harms and conserving biodiversity for our planet’s future. What […]
In New Guinea, megadiverse lowland forests are most at risk of deforestation
- Located at the edge of the western Pacific Ocean, New Guinea is a vast island where the biota of Asia and Australasia meet, making it a melting pot of unique plants and animals that occur nowhere else on the planet.
- Development pressure is ramping up across the island, however, opening up landscapes to new roads, industrial logging and agricultural conglomerates pushing biofuel agendas.
- New Guinea’s low-elevation forests, which represent some of the world’s last vestiges of ancient lowland tropical rainforest, are particularly imperiled, according to a new study.
- To avert tragedy, the authors urge policymakers to improve land-use planning systems, focus on retaining intact forest landscapes, and strengthen the rights of the people who live among them.

Capuchin monkeys on Panama island seen stealing howler monkey babies
On a remote Panamanian island, researchers have observed for the very first time young male capuchin monkeys stealing howler monkey babies, according to a new study. Since 2017, researchers have used camera traps to study Panamanian white-faced capuchins (Cebus imitator) on Jicarón Island in Coiba National Park, where the monkeys use stone tools to crack […]
Study finds fast traffic noise is infuriating Galápagos warblers
- A noisier world makes it challenging for birds, which primarily rely on sound to communicate, and many are forced to change their behavior to cope with their clamorous environment.
- A recent study looked at how traffic noise impacts communication in male Galápagos yellow warblers (Setophaga petechia aureola), a common resident bird on the islands, and found that traffic noise increases aggression in birds living closer to roads.
- With traffic increasing in the biodiversity-rich Galápagos, conservationists worry about the impact of noise on birds, especially the yellow warblers, which are also the most common roadkill.

An alternative approach to bridge Indigenous knowledge and Western science for conservation (commentary)
- The idea of integrating Indigenous and Western knowledge systems is often well-intentioned, but ultimately misguided, write the authors of a new commentary who were part of a project for WCS Canada and the Tr’ondëk Hwëch’in First Nation in the Yukon.
- Their new study offers an alternative approach, in which these knowledge systems can exist independently and simultaneously, without seeking to control or validate one another.
- “It is our hope that this work sparks a greater conversation about land-use planning across Canada, in pursuit of a world where wildlife and people can thrive in healthy and valued lands and seas,” the authors write.
- This article is a commentary. The views expressed are those of the authors, not necessarily Mongabay.

Scat-sampling DNA tool shows potential in African carnivore conservation
Researchers have developed a noninvasive DNA tool to help monitor hard-to-trace African carnivores, including caracals and leopards, making it potentially useful in the conservation of elusive and increasingly threatened species. “Carnivores are really difficult to study/observe in the wild, and even if a fecal sample is found, it is often difficult to determine which species […]
