Mongabay India wins best science podcast at Publisher Podcast Awards
Mongabay India’s 2024 podcast miniseries “Wild Frequencies” bagged the “Best Science and Medical” category at the Publisher Podcast Awards ceremony in London on June 11. The podcast is a three-episode series that tells stories of how researchers in India use the science of bioacoustics, or animal sounds, to better understand the lives of wildlife, such […]
“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 […]
Fungi are our climate allies | Against All Odds
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 […]
Countries failing to stop illegal bird killings despite 2030 commitment: Report
Most countries that pledged to reduce the number of birds being illegally killed along an important migratory route in Europe and the Mediterranean region are failing to do so, a new report shows. For the report, conservation organizations BirdLife International and EuroNatur tracked the progress of 46 countries in Europe, Africa and the Middle East, […]
Study unveils mystery of monkey yodeling — and why humans can’t compete
- Researchers found that New World monkeys can produce extreme yodeling-like sounds by rapidly switching between their vocal folds (for low tones) and specialized vocal membranes (for high tones), achieving frequency jumps up to 12 times greater than humans can manage.
- Scientists conducted their research at Bolivia’s La Senda Verde animal refuge, using recordings and electroglottographs on live monkeys.
- Humans lost these vocal membranes during evolution, trading vocal gymnastics for more stable speech that’s easier to understand.
- The complex vocalizations likely help monkeys manage social relationships and grab attention in the rainforest.
Vortex predator: Study reveals the fluid dynamics of flamingo feeding
Flamingos, often pictured standing still with their heads submerged in water, make for a pretty picture. But peep underwater, and you’ll find the tall, elegant pink birds bobbing their heads, chattering their beaks, and creating mini tornados to efficiently guide microscopic prey into their mouths, according to a new study. “Think of spiders, which produce […]
Radio tags help reveal the secret lives of tiger salamanders
- Scientists are using radio telemetry to map out the home range and habitats of tiger salamanders in the Hamptons in New York.
- Tiger salamanders spend most of their time in burrows underground; they emerge during breeding season and lay eggs in seasonal pools.
- Studying their movements and how far they move from the pools is challenging because of their underground lifestyle.
- With the help of radio transmitters, scientists have found that the salamanders move greater distances than previously thought; they were also found to burrow under fields.
World’s oldest ant fossil found in Brazil, dating back 113 million years
A “remarkably well-preserved” fossil discovered in Brazil, dating back 113 million years, is now the oldest ant to have ever been found by scientists, a new study has revealed. The ancient fossil was found preserved in a limestone and “represents the earliest undisputed ant known to science,” the authors write in the study. The limestone, […]
Antibiotic pollution widespread in world’s rivers, study finds
Nearly a third of all antibiotics that people consume end up in the world’s rivers, a new study finds. This could potentially harm aquatic life and impact human health by promoting drug resistance, researchers say. Antibiotics, critical for treating various bacterial infections, are widely consumed by people, livestock and aquaculture fish, but the drugs are […]
Malagasy wildlife champion wins top global conservation award
Malagasy scientist Lily-Arison René de Roland has been announced as the winner of this year’s Indianapolis Prize, which recognizes “extraordinary contributions to conservation efforts.” In its announcement, Indianapolis Zoo, which presents the award, highlighted René de Roland’s scientific and conservation work that has led to the discovery of several species and the establishment of four […]
Invasive whiteflies pose a new threat to Bangladesh’s cash crops
- The invasion of sap-sucking whiteflies in Bangladesh’s agricultural farms, especially in those of coconuts, bananas and guavas, has become a serious concern among farmers as it can cause widespread damage.
- Farmers first noticed these insects in 2019 on coconut plants, and observed they affected the growth of the plants and yields. Research shows whiteflies have already made 61 types of plants as their hosts in Bangladesh.
- Though the researchers have yet to confirm how they entered the country, they suggest it could be via imported high-yielding coconut plants in 2014 and 2015.
- Researchers suggest deploying a parasitoid wasp, Encarsia guadeloupae, which is considered to tackle the invasion of the whitefly.
Sumatran tiger protection needs more patrols, tougher penalties, study finds
- A new study on Sumatran tiger conservation in Indonesia’s Gunung Leuser National Park underscores that poaching remains the top threat, despite extensive patrols and antitrafficking efforts over the past decade.
- Researchers found that while patrols removed hundreds of snares and law enforcement increasingly pursued criminal charges, poaching rates remained high and tiger populations continued to decline in some areas.
- Despite stricter conservation laws and improved prosecution rates, the financial rewards of poaching still outweigh the penalties, limiting the deterrent effect on poachers and traffickers.
- The study recommends increasing patrols in high-risk areas, improving community engagement in law enforcement, and providing alternative livelihoods to reduce the economic lure of poaching.
New research sheds light on Canada lynx-snowshoe hare cycle, human impacts
- It’s long been known that snowshoe hare numbers in North American forests rise and fall dramatically in a predictable 10-year cycle. A year or two later, Canada lynx populations follow the same pattern.
- After decades of research, the dominant view is that the hare cycle is largely driven by predation, though there are still many mysteries to uncover.
- New research is shedding light on the lynx’s hunting behaviors and the asynchronicity of population cycles from region to region.
- Researchers are also looking at how human causes, including forestry practices, climate change and escalating wildfires, may be impacting lynx-hare cycles.
Even in intact Amazon forests, climate change affects bird populations: Study
- A recent study analyzed the behavior of birds that feed on insects in parts of the Amazon that have not yet been altered by human activity. Of the 29 species studied, 24 have gone through a reduction in population.
- The results point to climate change as the cause: Less rainfall and more severe droughts seem to be affecting the number of insects there, resulting in less food for the birds, which seem to be reacting by reproducing less in order to save energy.
- According to the study, an increase of just 1° C (1.8° F) in average dry season temperature in the Amazon would result in a 63% drop in the bird community’s average survival rate.
Study offers new tool to compare environmental impacts of crops
In a recently published study, researchers offer a new tool to compare how different crops affect the environment in different regions. Named PLANTdex, the tool assesses the environmental impact of a crop by considering five key indicators — greenhouse gas emissions, freshwater biodiversity loss, marine biodiversity loss, land biodiversity loss, and water resource depletion — […]
Angling for answers, this saltwater fishing group boosts research for better conservation
- Though anglers aren’t generally thought of as environmentalists, many people who fish are conservation minded, whether because it’s an outdoor pursuit, or because they wish to ensure future harvests.
- Whatever their reasons, there aren’t many groups that help anglers advocate for sustainable fishing regulations based on solid science, nor ones that also work to generate new data that helps them argue for better conservation.
- “Until we came along, there was no voice for those saltwater anglers who cared about conservation, but didn’t have enough time to put into it to really understand it,” says American Saltwater Guides Association vice president Tony Friedrich.
- His team not only helps its members articulate the need for conservation and regulation, they actively participate in developing data that helps managers set better limits, through projects like their GotOne App.
Singapore study says roadside flowers can improve urban butterfly biodiversity
Narrow strips of flowering plants along road edges can support high butterfly diversity, a recent study from Singapore has found. In late 2023, researchers surveyed 101 road verges — strips of green planted along the side of roads — across the tropical city-state of Singapore, recording 56 species of butterflies feeding on nectar from 96 […]
As renewable diesel surges, sustainability claims are deeply questioned
- Renewable diesel (RD), dubbed HVO (hydrotreated vegetable oil) by producers, is hailed by its supporters as a climate-friendly alternative to carbon-intensive fossil diesel. RD is a complex biofuel often made in retooled oil refineries from feedstocks including waste cooking oils, but also problematic animal fats and soy and palm oil.
- Renewable diesel substitutes easily for fossil diesel, so is touted as a climate-friendly transition fuel. Its use, mostly in vehicles, grew slowly in the past. Now, thanks largely to government-offered green subsidies, production is surging as firms widely expand uses to marine shipping, power plants, heating oil, and data center backup fuel.
- But critics are skeptical about industry claims of RD life-cycle greenhouse gas emission cuts of up to 95% over fossil fuel-derived diesel. They warn RD carbon releases will surge if renewable diesel sourcing is scaled up, triggering tropical deforestation as producers convert forests to energy crops, such as oil palm and soy.
- As the renewable diesel industry expands beyond Europe and the U.S., analysts warn it will be a false climate solution unworkable at scale, so production and use should be constrained. Independent monitoring is also needed to track feedstock supply chains to assure crops don’t have high carbon intensities or cause deforestation.
Hawaiʻi’s bone collector caterpillar wears spider’s victims to survive
Researchers in Hawaiʻi have described an unusual species of carnivorous caterpillar that scavenges in spiderwebs while wearing cast-off bits of the spider’s prey. Nicknamed the “bone collector,” the caterpillar belongs to the genus Hyposmocoma, commonly known as “fancy case” caterpillars because they make variously ornamented protective cases to live in. Endemic to Hawaiʻi, they decorate […]
Chimpanzees filmed sharing alcoholic fruits for the first time
Researchers have for the first time filmed wild chimpanzees feasting on alcoholic fruits together. It’s the “first evidence for ethanolic food sharing and feeding by wild nonhuman great apes,” they say in a new study. The research team, led by scientists at the University of Exeter, U.K., captured the footage on camera traps they set […]
Our responsibility for cetacean conservation grows with proof of their intelligence (commentary)
- In the search for other intelligent life in our galaxy, we must look to the oceans before we turn to the stars, states the writer of a new commentary.
- In recent years, cetacean researchers have shown that whales, dolphins and porpoises live socially complex lives that require elaborate communication systems, and possibly even language.
- “If people can understand what they have in common with an animal that is seemingly so alien on the surface, it would allow for a greater extension of empathy,” and therefore greater conservation efforts, the writer argues.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Ronan the sea lion outperforms humans at keeping a steady beat, study finds
A sea lion named Ronan is better able to keep a beat than the average human, a new study finds. Such ability in animals is generally thought to be unique to humans and some birds, but Ronan’s performance challenges those assumptions, the study’s researchers say. Ronan, a California sea lion (Zalophus californianus), was born in […]
In Cameroon’s forgotten forests, gorillas and chimps hang on
- Many forest reserves in southern Cameroon, despite being highly degraded and fragmented, harbor significant biodiversity.
- A recent study using camera traps in two such forest reserves captured the first evidence of great apes — a gorilla and several chimpanzees — foraging in and navigating the mosaic of fragmented landscapes.
- Some of the videos show apes and humans using the same parts of the forests at different times, highlighting the risk of human-ape conflicts that could impact the already threatened great apes.
- Conservationists say the presence of great apes outside protected areas indicates the need to protect these areas, and that further research is needed to understand how great apes use fragmented landscapes close to human communities.
Alwyn Gentry died young, but left a forest’s worth of ideas behind
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. Long before “biodiversity hotspot” became a conservation cliché, Alwyn Howard Gentry was painstakingly mapping them — one vine, one tree, one tenth-hectare transect at a time. His early death in 1993 at age 48, in a plane crash […]
Malice or memory lapse? Why honeyguides sometimes lead hunters to danger
Researchers may have finally cracked the centuries-old mystery of why African honeyguide birds sometimes lead human honey-hunters to dangerous animals instead of bees: they could just be recall errors. Honeyguides (Indicator indicator) are famed for guiding honey-hunters to wild bees’ nests in exchange for rewards of beeswax. But since the 1600s, Indigenous accounts have described […]
Indonesia’s deforestation claims under scrutiny over ‘cherry-picked’ data
- Researchers say Indonesia’s claim of a 90% deforestation drop over the past decade is misleading due to cherry-picked data and an extreme baseline year.
- The actual decline is closer to 50-69%, driven by earlier policies and reduced forest availability in many regions.
- Deforestation is rising again, especially in Papua and Sulawesi, fueled by palm oil, pulpwood, and mining expansion.
- Civil society groups are crucial in tracking and exposing forest loss amid conflicting government policies and rising environmental threats.
Kumana, a historic national park in eastern Sri Lanka, emerges as leopard stronghold
- A new study reports a notably high density of Sri Lankan leopards (Panthera pardus kotiya) in eastern Sri Lanka’s Kumana National Park, highlighting the park as a significant habitat for the leopards.
- Using camera traps, the study recorded more than 90 leopard encounters, including 34 identified individual leopards, captured on film across a 16-month survey period.
- Since 2017, a citizen science program also has recorded 80 individual leopards in Kumana, using a naming system to identify each individual.
- Kumana, famed for its wetland birdlife, is now emerging as a key leopard habitat, offering potential for leopard tourism and easing visitor pressure in congested parks like Yala in the island’s south.
‘Puma detectives’ highlight wildlife where Brazil’s Cerrado meets the Atlantic Forest
- A project in the Brazilian state of Goiás is monitoring the routes and distances traveled by pumas, known locally as suçuaranas, to understand how the species lives in environments that have been modified by human activities.
- The mapping is fundamental for strengthening the research carried out inside the ecological corridor stretching between two important state parks in Goiás, one in the Cerrado savanna biome and the other in the coastal Atlantic Forest.
- The project, called Suçuaranas Detetives (Puma Detectives) is part of a broader project involving education and awareness-building programs on peaceful coexistence between rural communities and the ecosystems in Brazil’s central regions.
A Honduran reef stumps conservationists with its unlikely resilience
- The latest “report card” on Mesoamerica’s coral reefs made clear that 2024’s hottest-ever recorded summer temperatures devastated some of the region’s most iconic reef sites.
- But against all odds, a reef in Tela Bay on Honduras’s Caribbean coast, composed largely of critically endangered elkhorn corals (Acorpora palmata), displays remarkable health.
- Known affectionately as “Cocalito,” this patch of coral is raising urgent questions about what qualities endow coral with heat resilience and whether they can be harnessed to help save other reefs.
Winter warming and rain extreme events pose overlooked threat to Arctic life
- Accelerated Arctic warming is reshaping the polar environment, but focusing only on the impacts of long-term annual temperature rise can miss key consequences of shorter-lived, but extreme, weather shifts coming as a result of climate change.
- A new meta-analysis highlights how extreme weather events in winter, such as rain-on-snow and temperature spikes, are increasing across the Arctic — though not every region gets the same extreme whiplash weather.
- Even short surges of wild winter weather — 24 hours of rainfall on snow-covered ground, for example — can decimate animal and plant populations and change an ecosystem for generations. One such rain-on-snow event in 2023 killed nearly 20,000 musk oxen in the Canadian Arctic.
- Better understanding of Arctic winter weather extremes (along with their immediate and long-term effects on flora and fauna), and factoring these into climate models, could help create more accurate, effective, region-specific conservation plans.
Blue whale decline in Sri Lanka tied to climate and human activity
- A resident population of blue whales has for many years lived in the coastal waters of Sri Lanka, but in recent years sightings of the animals have declined rapidly.
- With multiple pressures on these massive creatures — from ship traffic on one of the world’s busiest shipping lanes, to disturbance from whale tourism, pollution and surface sea temperature rise and climate change — there are several possible factors for the disappearance of the whales.
- Sri Lanka’s leading marine researchers agree that increasing sea temperatures in the North Indian Ocean, warming at the fastest rate of any of the world’s oceans, have likely pushed the whales to new waters.
PHOTO ESSAY Wind-blown sand scouring life off a Southern African landscape
- Botany professor emeritus Timm Hoffman and his colleagues are seeing eddies of dune sand piling up around quiver trees at study sites in northwestern South Africa.
- Hoffman has been studying the iconic trees for 20 years — the sand, which in places has formed drifts up to 2 meters (6.6 feet) deep, is new.
- Five years ago, environmental scientists noted an increase in wind-blown sand plumes in the arid areas on both sides of the South Africa border for reasons that are not entirely clear.
- This spreading sand is killing off the succulent vegetation adapted to this climate, threatening this austerely beautiful region’s biodiversity and the livelihoods of shepherds and farmers who call it home.
Indris like to “move it”
Madagascar’s Indri indri lemurs can carry a tune. Through collecting songs and calls produced by 20 indri groups in Madagascar’s rainforests over the span of 15 years, scientists have found that indri songs exhibit rhythmic patterns that are common in human music — providing a pathway for decoding the evolution of music. Indris are critically […]
We can’t plant our way out of climate change
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. Forests with diverse tree species are more resilient to climate extremes and better at storing carbon, according to recent studies conducted in China and Panama. Though hardly groundbreaking, these findings reinforce an increasingly evident truth: Biodiversity in reforestation […]
Discovery of critically endangered bat in Rwanda leads to conservation talks
- Bats are one of the most diverse orders of mammals and represent an important component of ecological balance. They may make up a large portion of the mammal diversity — including in countries like Rwanda where much of the natural forest and savannah habitats have been lost, changed or degraded.
- Researchers recently discovered two rare bat species in Rwanda’s Nyungwe National Park, and the IUCN lists 54 species of bats as occurring in the country.
- Research shows that killing bats to control zoonotic diseases can make things worse.
- Several studies show that bats are important predators of insects and are, therefore, a natural asset for agrarian productivity, suppressing pest populations.
The wisdom of the elders: Why the oldest animals matter
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. In the twilight of their lives, the world’s oldest creatures carry the weight of wisdom, experience, and resilience. Yet, these elders — fish that spawn in abundance, coral that shelters marine life, or elephants that guide their herds […]
New research finds substantial peat deposits in Colombia’s conflicted Amazon
- A new study of Colombia’s lowland forests and savannas finds that the nation may have extensive peatlands — organic wetland soils formed over thousands of years — holding as much as 70 years’ worth of Colombia’s carbon emissions. Protecting them from agricultural development is essential to preventing greenhouse gas releases.
- Researchers made peatland estimates by taking sediment cores in 100 wetlands, quantifying peat content, then building a model to predict locales for other peat-forming wetlands using satellite imaging. Peat was found in unexpected ecosystems, such as nutrient-poor white-sand forests, widespread in northern South America.
- Sampling in many locations was only possible due to the ongoing but fragile peace process between the Colombian government and armed rebel groups. In some places, security has already deteriorated and further sampling is unsafe, making this study’s scientific estimate a unique snapshot for now.
- Most Colombian peatlands are remote, but deforestation is intensifying along the base of the Andes, putting some wetlands at risk. Colombia’s existing REDD+ projects have been controversial, but opportunities may exist to combine payments for ecosystem services with peacebuilding if governance and security can be improved.
Global agarwood trade heavily dependent on wild, threatened trees: Study
- The global agarwood trade heavily depends on wild-harvested endangered tree species, despite international regulations for protection, with significant volumes going undocumented in official trade records, a new study reveals.
- About 70% of the trade depend on Aquilaria filaria and Aquilaria malaccensis, both threatened species, sourced from the wild, raising major sustainability concerns. Meanwhile, there are some tree species that are not even covered by CITES, the global wildlife trade convention.
- Due to discrepancies between CITES and customs data, along with weak enforcement and outdated regulations, researchers suggest the illegal trade is far larger than reported.
- Researchers urge stronger monitoring, updated data, expanded species protection, and a shift to cultivated sources. They also call on consumers and wealthy importers to support conservation and governments to promote sustainable practices.
Pangolins help biodiversity recover after fires
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries.

As the world’s most trafficked mammal, their numbers have been decimated by poaching for scales […]
Loss of great white sharks triggers domino effect down food chain, study shows
- A new study shows how the disappearance of an apex predator, the great white shark, from South Africa’s False Bay triggered changes throughout the food chain.
- With the loss of the top predator in the area, populations of its prey species, such as fur seals and sevengill sharks, increased; the latter’s prey, meanwhile, small fish and smaller benthic sharks, declined.
- The changes also coincided with shifts in the behavior of animals that live in the orbit of great whites.
- Over a 20-year period, the authors observed a significant drop in numbers of great white sharks beyond the study area, raising concern that the overall population of the protected species might be in decline.
Why captive elephants formed a circle during the San Diego earthquake

Increasingly, however, the discipline is moving indoors. A […]
Vital Mekong fish corridors tracked for first time, but funding cuts threaten future research
- By implanting fish with small electronic transmitters, researchers were able to track key migration corridors in the Mekong River.
- The findings underscore the threat that dozens of planned dams along the Mekong will cut off these vital migratory paths.
- The study, which the lead author describes as a “pilot effort,” was funded by USAID; the funding gap caused by the U.S. foreign aid freeze leaves the future of such research in question.
Locals, researchers race to save unique biodiversity of PNG’s Torricellis
Torricelli Mountains, a tiny mountain range in northern Papua New Guinea, is estimated to host roughly 4% of the world’s known species, many found nowhere else on Earth, Mongabay’s John Cannon reported in March. “I mean, for 0.003% of the world’s land area — it’s a ‘wow’ factor for me,” Jim Thomas, CEO of the […]
AI uncovers how birds remix their songs over time
- A new study has confirmed the belief that birdsongs evolve as a result of age, population dynamics and movement of the birds.
- Researchers gathered thousands of hours of audio of great tits (Parus major) and used artificial intelligence to analyze songs in the data.
- They found that birds that move around a lot tended to know the popular songs, while the ones that didn’t had pockets with unique songs.
- While older birds were found to act as repositories of old songs, mixed-age bird communities were found to have more song diversity.
Africa’s growing cities are endangering birdlife (commentary)
- In Africa, urban land cover is expected to triple by 2030, and the potential impact on birds and biodiversity is particularly alarming, a new op-ed argues.
- A recently published study used citizen science data from Kenyan and Nigerian bird-mapping projects to uncover insights into how urbanization affects birds, their diversity and ecological functions in these nations.
- “As urbanization has intensified, the variety of bird species and their roles in the ecosystem shrinks, resulting in more uniform communities with generalist species,” author Bello Adamu Danmallam writes.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Plastic-eating seabird chicks show signs of organ failure and cognitive decline
- Seabirds and other marine wildlife are ingesting an increasing amount of plastics as pollution in the ocean rises.
- A recent study finds that sable shearwater chicks that consume high levels of plastics have abnormal levels of certain proteins in their blood, including some that suggest tissue damage, multiple organ failure and cognitive decline, despite showing no signs of obvious ill health.
- Conservationists say the study’s findings in young chicks show plastics could threaten entire populations of sable shearwaters.
- Although the study’s findings are limited to a single species, they raise concern for other marine life, say conservationists, who urge immediate action to reduce marine plastic pollution.
Why conservation research findings are rarely surprising
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. “We already knew that.” I frequently receive complaints from readers about findings in scientific papers being commonsense or obvious. And yes, it’s true: science often confirms what we’ve long suspected or seen in practice. By its nature, science […]
Diverse forests and forest rewilding offer resilience against climate change
- Recent studies from two long-running planted forest experiments in China and Panama find that increasing tree diversity in reforestation efforts can boost resilience in the face of climate change, among other benefits.
- Researchers elsewhere propose a “rewilding-inspired forestry” approach that aims to restore biodiversity, aid climate mitigation and bolster forest ecosystems — an approach that requires a significant shift from current forestry practices.
- However, scientists underline that while reforestation and forest rewilding can contribute to curbing climate change, they have their limits and must be combined with deep carbon emissions cuts and conservation of existing forests.
Giant rats trained to sniff out illegal wildlife trade
From land mine detection to sniffing out illegally trafficked wildlife parts, a group of trained African giant pouched rats in Tanzania is proving a valuable partner for humans, Mongabay’s Lucia Torres reported in February. In the 1990s, Belgian industrial engineer Bart Weetjens was exploring ways to detect land mines when he thought of rats: they’re […]
Even the Gulf of Aqaba’s ‘supercorals’ bleached during 2024 heat wave
- Scientists have long considered the corals in the Gulf of Aqaba in the northern Red Sea to be uniquely resilient to extreme temperatures.
- For the first time on record, however, the heat wave of 2024 bleached some of these super-resilient corals in Israeli and Jordanian waters, according to scientists.
- Scientists studying the episode’s severity and extent estimate that perhaps 5% of the corals in their study area in Israeli waters bleached during the oppressive Northern Hemisphere summer; a small fraction died, but most recovered over the relatively cooler months that followed.
- Tackling threats like pollution that could reduce the corals’ ability to withstand extreme heat is the best way to protect them from rising marine temperatures, and scientists say an oil terminal that sits barely half a kilometer from some of the “supercorals” poses an imminent threat.
Outlook improves for wattled crane in South Africa
In what’s being hailed as a conservation success, the wattled crane has seen its conservation status in South Africa improve from critically endangered to endangered.

How is conservation preparing for a much hotter world? Experts share
- Fifty years from now, in 2075, the world will be considerably hotter, perhaps as much as 3-5° Celsius (4.5 to 9° Fahrenheit) above the pre-industrial average.
- Experts say we need to focus on building greater resilience into ecosystems now to help species get through the next half century.
- We should be protecting large landscapes, including altitudinal gradients, according to experts.
- We should also be focusing on good management, community relations, rewilding and restoration.
Dugong numbers plummet amid seagrass decline in Thailand’s Andaman Sea
- Thailand’s dugongs are disappearing fast, reflecting an unfolding crisis in the region’s seagrass ecosystems.
- Seagrass beds on Thailand’s Andaman Sea coast that support one of the world’s most significant populations of dugongs have died off in recent years, creating an increasingly challenging environment for the charismatic marine mammals.
- Scientists point to a combination unsustainable coastal practices and climate change as the main factors driving the decline.
- Government agencies, marine scientists and volunteers are taking emergency steps to save the remaining dugongs, but experts warn their long-term survival in Thailand depends on fixing the root causes of the seagrass loss.
Thailand’s ‘second’ tiger population stable, but barriers to expansion persist
Populations of the critically endangered Indochinese tigers in eastern Thailand’s forest reserves remained stable between 2018 and 2021, but a shortage of prey and the presence of highways prevented their expansion to promising habitat, a recent study has found. Scientists have been monitoring Indochinese tiger (Panthera tigris corbetti) populations across the Dong Phayayen-Khao Yai (DPKY) […]
122 companies responsible for a third of present day sea-level rise: Study

While bonobos (Pan paniscus) produce grunts, peeps, whistles and hoots, they also combine these calls […]
Conserving vultures in Southern Africa may provide substantial economic gain: Report
- A new report has found that conserving vulture populations in Southern Africa could have potentially huge economic value. Many vulture populations in Africa are in sharp decline, the authors highlight.
- The report, published by the NGO BirdLife, attached a value to a range of ecosystem services — including an important sanitation role and their existence for future generations — at $1.8 billion for the region.
- This illustrates the importance of conserving vultures and addressing the multitude of threats facing them, the NGO says.
- But other vulture experts say caution is needed in interpreting some of their findings, as assigning an economic value to traditional medicine and belief-based use could lead to the demise of entire populations.
What do CITES data tell us about the legal wildcat trade?
- All 40 species of wildcats are traded globally, both legally and illegally, posing conservation concerns for big and small cats.
- Wildcats are listed on CITES, the global international wildlife trade agreement, and analysis of data on wildcats for the last 25 years shows that most trade permits are issued for lions, followed by leopards, bobcats, Canada lynx and tigers.
- Although drivers of the trade vary for each species, data show a demand for body parts such as skin, claws and bones, and live animal trade is common for the most-traded wildcat species.
Lithium Triangle mining may strain water sources more than expected, study says
- Measuring water availability for lithium extraction can still be unpredictable, especially in the high-altitude Lithium Triangle in Chile, Argentina and Bolivia.
- Current models can overestimate how much water is available, potentially exacerbating scarcity for local communities, according to a new study in Communications Earth and Environment.
- The study suggests using a more accurate model as well as improving transparency and resources for gathering observational data where lithium is being extracted.
Study delves into increase in humpback whale sightings in UK and Ireland
Earlier this year, U.K. media reported an increase in humpback whale sightings in British and Irish waters.

Meanwhile, the nonprofit Sussex Dolphin Project reported more than 50 sightings from Sussex in […]
Amid fuzzy data, scientists urge monitoring of Hong Kong’s tokay gecko trade
- Thousands of tokay geckos (Gekko gecko), native to South and Southeast Asia, are sold each year in Hong Kong’s traditional Chinese medicine (TCM) pharmacies.
- Recent studies have raised questions on the sustainability of this trade and the origins of the geckos, as vendors’ claims don’t agree with data in the CITES database, exposing data discrepancies in legal trade.
- Without stricter oversight, these discrepancies could result in unsustainable trade and facilitate illegal trafficking of tokay geckos in the region, say conservationists, who urge countries and CITES to better monitor the trade.
Traffic noise turns Galápagos warblers into angry birds

Rare polar bear cub footage offers crucial conservation insights
- Scientists have captured rare footage of female polar bears and their newborn cubs emerging from maternal dens in the Arctic.
- Using remote cameras and satellite collars, researchers were able to track down polar bear dens in Norway’s Svalbard region and get insights into their behavior.
- On analyzing the data, researchers found that the bears typically stayed in and around the dens for 12 days after first emerging from them; they were also found to abandon the dens earlier than previously thought.
- Polar bear denning and the subsequent den emergence is a crucial period during which cubs transition from the warm environment of the dens to the harsh environment outside; the amount of time cubs spend in the dens is believed to have implications for their survival.
The vast venomous world of plants, fungi, bacteria: Study

Colombia’s coffee farmers try to balance innovation and tradition to adapt to climate change
- Researchers and coffee farmers in Colombia are trying to find strategies to adapt to unpredictable weather, rising temperatures and erratic rainfall, which are disrupting Colombia’s coffee industry by fueling pests and diseases like the coffee berry borer and coffee leaf rust.
- Cenicafé, the national coffee research center, is continuously developing new hybrid coffee varieties that are resistant to diseases and climate change for farmers, but pests are evolving, requiring more research and genetic diversification.
- Some farmers are restoring the much slower traditional shade-grown coffee practices through reforestation and agroforestry, which help them access premium high-end coffee markets while tackling and adapting to climate change.
- With the limited options presented, some researchers say coffee growers must at times choose between high-yield hybrids or eco-friendly organic farming, weighing sustainability against economic survival.
For wandering elephants, path of least resistance could help map out safe corridors

Polar sea ice continues steep decline; but will a troubled world notice?
- Polar sea ice has reached record, and near-record, lows for this time of year, pushing the pace of global warming and alarming scientists. The just declared 2025 Arctic sea ice extent winter maximum is the lowest on record, at 14.33 million km² (5.53 million mi²). That’s 80,000 km² (31,000 mi²) below the previous low seen on March 7, 2017.
- The 2025 Antarctic sea ice extent summer minimum on March 1 tied for the second lowest on record, at 1.98 million km² (764,000 million mi²). The all time record Antarctic summer low was 1.79 million km² (691,000 million mi²) reached on February 21, 2023. Polar ice satellite records have been continuous since 1979.
- Sea ice loss is expected to continue its slide based on climate models, with scientists warning that the Arctic landscape is likely to be transformed beyond recognition within decades. Sweeping changes will devastate Indigenous polar communities, disrupt Arctic ecosystems, and ultimately lead to the demise of iconic polar wildlife.
- Inhospitable polar conditions continue challenging scientists’ ability to gather data and make precise polar forecasts vital for knowing our climate future. But it may be even more challenging to raise public awareness and political will to reduce carbon emissions and reverse polar ice loss before it passes dangerous tipping points.
Researchers find new killifish species in Kenya
- According to a new study, a new species of killifish, Nothobranchius sylvaticus, has been found in seasonal swamps in the ephemeral marshes of Kenya’s historic Gongoni Forest at the coast.
- Scientists from Canada, France, Kenya and South Africa report that the severely restricted habitat of the seasonal Mkurumudzi River in southeastern coastal Kenya is threatening the survival of the fish species.
- The killifish, a unique species with iridescent blue scales, red markings and vibrant fins, has been deposited at the National Museums of Kenya and the Royal Museum for Central Africa.
- An expert is calling for the formal designation of the Gongoni Forest as a key biodiversity area and local communities’ engagement to protect the small freshwater fish, ensuring its recovery and avoiding threats.
Peru’s rare peatland swamps at risk as illegal gold mining expands
- Gold mining in Madre de Dios, Peru, is destroying rare peatland swamps that serve as critical carbon sinks, a new study found.
- The study, published in Environmental Research Letters, used 35 years of NASA Landsat satellite data to track the spread of gold mining.
- It found that more than 550 hectares (1,360 acres) of peatland have been destroyed by mining over the last 35 years, with over half of it occurring in the last two years.
- At least 63 out of 219 peatland areas have been affected by mining, putting more than 10,000 hectares (about 25,000 acres) at immediate risk, with the possibility that as much as 14.5 million metric tons of carbon could be released into the atmosphere, the study said.
A century later, a rare mushroom with a curious shape emerges in Sri Lanka
- Documented just once in 1919 at the Royal Botanical Gardens in Sri Lanka, an elusive mushroom has resurfaced more than a hundred years later, causing excitement among mycologists and nature lovers alike.
- The fungus is known for its phallic shape and foul-smelling spore mass, which attracts insects for spore dispersal — a unique strategy among fungi, which otherwise mostly use wind to disperse the spores.
- After the publication of a research paper, at least five separate observations from different parts of the country were reported highlighting that the mushroom may survive in many places.
- Mycologists call for greater attention to fungi in biodiversity research and conservation, as many species may remain hidden — or risk disappearing unnoticed.

As apes adapt to human disturbance, their new behaviors also put them at risk: Study
- Worldwide, the most frequent causes of disturbances to ape habitats are land conversion for agriculture or logging, a recent study concludes.
- The study found that the most common ways apes adapted to habitat change included foraging for human crops, changing nesting patterns, and traveling along human-made paths.
- These changes can help apes survive in the short term, but can increase long-term risk, especially when behaviors like crop foraging bring them into conflict with humans.
- While some patterns were observed worldwide, human responses to behaviors like crop foraging varied widely, highlighting the need for local voices and priorities to be a central part of conservation planning.
Plastic pollution cuts into fishers’ livelihoods in Ecuador and Peru
- A new study in Peru and Ecuador has found that artisanal fishers are losing revenue due to prolific plastic pollution in the ocean.
- Researchers surveyed 1,349 artisanal fishers in Ecuador and Peru and found that the more waste generated locally, the greater the financial losses.
- This is reflected in the national economy, with losses in Ecuador and Peru’s domestic product from fisheries.
- The study is part of the Pacific Plastic: Science to Solutions initiative, which is represented on an intergovernmental committee currently negotiating a treaty on plastic pollution.
Africa’s last tropical glaciers are melting away along with local livelihoods
- Africa’s remaining tropical glaciers are rapidly disappearing as greenhouse gas emissions drive global warming.
- New maps published by Project Pressure show the Stanley Plateau glacier, in Uganda’s Rwenzori Mountains, lost nearly 30% of its surface area between 2020 and 2024.
- The Rwenzoris’ glaciers are a vital source of water for more than 5 million people living in the plains below the mountain range; they also have cultural significance.
- Project Pressure’s ongoing surveys, carried out in collaboration with the Uganda Wildlife Authority, are intended to provide local authorities with data needed to adapt to the loss of the glaciers and other impacts of climate change.

With climate change, cryosphere melt scales up as a threat to planetary health
- Earth’s cryosphere — comprised of ice sheets, glaciers, permafrost and snowfall — is in a rapid state of flux due to escalating climate change, with numerous studies underlining the grave risks posed by the thaw.
- Today, that worldwide meltdown poses new threats to human lives — endangering freshwater supplies and food security while increasing the risks of natural disasters and disease outbreaks. Cryosphere loss poses immense dangers to the environment, agriculture, economy and society according to a new report.
- If emissions continue unabated, these problems will only worsen. Scientists warn of compounding risks as cryosphere melt escalates, including sea level rise, the slowing of ocean currents, and the triggering of feedbacks that will add to climate change.
- 2025 is designated the International Year of Glaciers’ Preservation. Experts are calling for drastic cuts to carbon emissions because each fraction of a degree of warming avoided counts toward the preservation of the cryosphere along with the ecosystem services that ice, snow and permafrost provide.
Fish-tracking robot aims to make fishing more sustainable in developing nations
- Israeli scientists have developed a solar-powered underwater robot called SOUND that can roam autonomously for five days at a stretch, counting fish and communicating its findings back to observers onshore.

- Executive producers Rick Smith and Peter Raymont explore how humans are becoming “plastic people” with microplastic contamination beginning before birth and persisting after death.
- Nations are negotiating a UN treaty on plastic pollution to address the estimated 400 million tons produced annually, with experts calling for eliminating unnecessary plastic use and banning toxic formulations.
- The film will be screened in Washington, DC, on March 29 at the 2025 DC Environmental Film Festival, where Mongabay is a media partner.
Seal ‘oceanographers’ reveal fish abundance in Pacific Ocean’s twilight zone
- The open ocean’s twilight zone, a vast deep ecosystem rich in fish biomass, is poorly understood because it is expensive and challenging for humans to reach its depths 200–1000 meters (660–3,280 feet) below the surface.
- A new study used northern elephant seals (Mirounga angustirostris) — marine predators that forage in the twilight zone — to help understand fish abundance deep down, both five decades into the past and two years into the future.
- The findings illustrate how apex marine predators, such as elephant seals, can serve as sentinels in understanding how fish abundance cascades through marine food webs.
- Given increased interest in fishing in the twilight zone and the unfolding effects of climate change, seals and other deep-diving marine predators could help keep an eye on changes in the oceans’ depths.
Counting whales by eavesdropping on their chatter, with help from machine learning
- Scientists have combined passive acoustic monitoring, machine-learning tools and aerial surveys to estimate the population of North Atlantic right whales in Cape Cod Bay.
- Using the method, researchers from Cornell University in the U.S. were able to estimate the daily population of the whales over a period of four months.
- While passive acoustic monitoring has helped scientists around the world detect the presence of whales, it’s often challenging to estimate population numbers from the data, especially for species like North Atlantic right whales that have highly variable call rates.
In a land where monkeys are seen as pests, Sri Lanka’s white langurs are winning hearts
- A rare population of leucistic, or partially white, purple-faced langurs near Sri Lanka’s Sinharaja Forest Reserve has attracted ecotourism interest, even as monkeys in general are perceived by farmers as crop-raiding pests.
- Unlike albinism, leucism causes a partial loss of pigmentation, and researchers have documented around 30 white langurs in the area.
- The unique langurs have helped transform the village of Lankagama into an ecotourism hub, benefiting the local community and conservation efforts.
- The presence of white monkeys across Sri Lanka, including rare cases of albino primates, highlights the island’s rich biodiversity and the need for further research and protection.

It’s a crucial time for whales to fatten up, and a new study suggests some whale species announce an abundance of food […]
Sri Lanka calls for five-minute surveys to identify crop-raiding animals
- Sri Lanka’s agriculture suffers significant losses due to crop-raiding wildlife, especially elephants, monkeys, wild boars, giant squirrels, porcupines, and peafowls.
- An island-wide, citizen-assisted count of wild animals on agriculture land and in home gardens is planned for Mar. 15, lasting five minutes starting 8 a.m.
- Crop-raiding wild animals remain a significant challenge in Sri Lanka as cultivations suffer but the problem is exacerbated by limited scientific data, prohibitive costs and public opposition to certain solutions like culling.
- The forthcoming survey excludes major nocturnal raiders such as elephants, wild boars, and porcupines, raising questions on the effectiveness of the exercise, while some consider it a step in the right direction.
Breast milk contamination exposes Africa’s ‘forever chemicals’ problem
- Researchers warn that synthetic chemicals in various products, including carpets, clothes, furniture, adhesives, food packaging, and nonstick cookware, pose a significant threat to infants in Africa.
- Over the past two decades, the chemicals, known as per- and polyfluoroalkyl substances (PFAS), or “forever chemicals,” have become a significant public health concern in Europe and North America. Emerging data from African countries point to the pervasive nature of the problem in the continent.
- PFAS exposure is linked to liver damage, thyroid diseases, cancer, and reproductive health problems, and can be especially dangerous for infants and children, experts say.
- Countries like the U.S. are beginning to pass laws to control PFAS levels in drinking water systems. Still, regulations that target PFAS are “rare across African countries,” a recent study notes.

Ugandan researcher wins ‘Emerging Conservationist’ award for work on golden cats
- Ugandan conservationist Mwezi Badru Mugerwa has been awarded the Indianapolis Prize’s Emerging Conservationist Award for 2025.
- Mugerwa has dedicated the past 15 years working with local communities to stop the poaching of the African golden cat (Caracal aurata), a species endemic to West and Central Africa.
- He and his team at conservation organization Embaka are also using camera traps and artificial intelligence tools to monitor and survey the population of the species, and to gauge the impact of their work.
In the drylands of northern Kenya, a ‘summer school’ for young researchers
- In northern Kenya’s Isiolo county, young researchers who study pastoralism gathered for a week of training and lectures.
- Most of the researchers were from East Africa; many were themselves raised in pastoralist communities.
- Isiolo county, a semiarid rangeland where most people make their living herding livestock, has been hit hard by drought in recent years.
- The researchers said they wanted to change the “old narrative” about pastoralist communities and their relationship to the environment.
‘Misguided & lazy’ staff cuts at NOAA will hurt global science, experts warn
The Trump administration recently fired roughly 800 probationary employees from the U.S. National Oceanic and Atmospheric Administration (NOAA). Former NOAA workers warn that these cuts will have global repercussions, affecting nations and industries that rely on NOAA’s freely available data. NOAA collects and shares data, from the depths of the ocean to outer space and […]
Male African elephants develop distinct personality traits as they age, study finds
- Male elephants have distinct characters, and certain individuals within the society are influential and can have a positive psychological impact on the group, according to new research.
- The study also showed that adult males are positively influenced by the presence of younger and socially well-connected males.
- Male elephant societies are dynamic and consist of dominant hierarchies and complex social networks, which contribute to the expression of consistent behaviors.
- Understanding elephant personalities is critical for improved wildlife management and conservation, researchers say.
Study confirms that ant-eating aardvarks have a craving for buried melons
A new study has used camera-trap footage and scent analysis to confirm the unusual relationship between an African melon and the aardvark, an elusive ant-eating mammal found in sub-Saharan Africa. Cucumbers and similar melon-like plants generally display their fruits aboveground, but an African melon (Cucumis humifructus) buries its fruit about 20 centimeters (8 inches) underground, […]
Mangrove deforestation for commodities limits conservation funding in SE Asia
- Southeast Asia’s mangrove forests are still at risk of conversion for oil palm, rice and aquaculture, despite their immense potential for mitigating global biodiversity and climate goals.
- Commodity-driven deforestation and a range of climate change-related risks threaten the long-term survival of 85% of the region’s mangrove forests that could feasibly host carbon credit projects, a new study finds.
- The long-term risks undermine the integrity of blue carbon credits as a potential source of much-needed conservation funding, the study says, ultimately jeopardizing the capacity of mangroves to sequester carbon and provide ecosystem benefits.
- The authors recommend a diverse suite of conservation funding mechanisms rather than relying solely on blue carbon credits, and also urge greater investments in community-led mangrove initiatives.
Aiding natural pollination can boost cacao yields & climate resilience
- Climate change and rising temperatures pose a major threat to cacao production across the globe, with those impacts already felt in major producers such as Côte d’Ivoire and Ghana.
- A new study highlights several low-cost, low-tech solutions that support natural pollination, building climate change resilience and increasing cacao yields up to 20%.
- Those methods include upping amounts of leaf litter to improve insect pollinator propagation, increasing the density of cacao tree plantings, utilizing taller native shade trees and limiting agrochemical use.
- Separate research underlines how these agroforestry methods used on farms can be supported by nearby natural forests, further aiding farm productivity.
An Ecuadorian hotspot shows how forests can claw back from destruction
- The Ecuadorian Chocó Forest is a little-known biodiversity hotspot, under immense pressure from deforestation.
- A joint German-Ecuadorian team is studying how this tropical forest ecosystem rebounds after clearing.
- The project, called the Reassembly Research Unit, is based out of a lab in the Jocotoco Foundation’s Canandé Reserve.
- The findings so far indicate that tropical forests have a remarkable capacity to heal, given suitable conditions. The findings can inform vital regeneration strategies.
Study links African lion survival to prey availability
- A recent study finds that African lion populations are declining as their herbivore prey are as well, prompting a need to protect these prey species to reverse the trend.
- Preventing prey depletion can help improve lion reproduction and population growth in areas prone to poaching for bushmeat, a leading cause of the species’ decline, the study notes.
- “In areas with high protection, the annual probability of [lion] population growth was 89.3%, but in areas with low protection the probability of growth was only 30.2%,” the study reads.
- The study underscores the importance of conservation programs that consider surrounding communities as crucial allies in species protection, says an expert.
Pangolin burrows are biodiversity magnets in burnt forests, study shows
- As insectivorous, burrowing mammals, pangolins play a key role in our ecosystem by controlling insect populations, recycling soil nutrients and sheltering other animals in their abandoned burrows.
- A recent study provides the first evidence of Chinese pangolins’ role as ecosystem engineers, whose burrows help restore biodiversity in forest patches gutted by fires.
- Over a two-year period, the study found that areas with pangolin burrows had more plant and animal species richness and diversity compared to sites without burrows, proving that pangolins accelerate ecosystem recovery.
- Experts say the study’s findings serve as another reason to conserve the scaly mammals and reintroduce them back into the wild.
Vicuña poop creates biodiversity hotspots as glaciers retreat rapidly
- The vicuña, a wild relative of the llama, could help reestablish plants in barren areas where glaciers have melted, according to a recent study in the high Andes of Peru.
- As vicuñas tend to poop in the same places, they establish communal latrines where soils have much higher moisture, organic matter, nutrients and microorganisms than surrounding areas formerly covered by ice.
- Researchers say they believe these more nutrient-rich soil patches can speed up plant colonization by as much as a century and provide refuge for plant species moving uphill as temperatures increase.
- Peru is losing its glaciers at a worrying speed, with research pointing out that in the Central Andes, between 84% and 98% of their glaciers might disappear by 2050.
Bangladeshi researchers pin hopes on irrigation method with real-time methane monitoring
- Bangladeshi rice researchers’ concern over a Bloomberg report about methane emission resulted in the installation of a real-time data-providing GHG emission measurement laboratory.
- The new lab aims to refine Bangladesh’s piloting of the Alternate Wetting and Drying (AWD) method, which reduces methane emissions from rice fields.
- Researchers expect the precise data to improve AWD adoption to help meet Bangladesh’s Nationally Determined Contribution (NDC) commitments.
Only 17% of peatlands, vital to curbing climate change, are protected, study finds
- Just 17% of peatlands worldwide are protected, according to a new study, despite the fact that they hold more carbon than all the world’s forests.
- Peatlands are waterlogged accumulations of dead, partly decomposed vegetation, and are scattered widely from the northern latitudes through temperate zones to the equatorial tropics.
- The new maps show that more than 25% of peatlands overlap with Indigenous territories, an area of some 1.1 million square kilometers (about 425,000 square miles); much of that land doesn’t overlap with other forms of protection, providing an opportunity to keep peatlands intact through the strengthening of Indigenous land rights.
- Conservation scientists see targeting peatlands for protection as “low-hanging fruit” to deal with climate change because they’ve stockpiled so much carbon on only about 3% of land on Earth.
Indigenous people cut down trees as solar energy remains inaccessible and costly in DRC
- Solar energy, which researchers say offers much potential to meet the Democratic Republic of Congo’s energy needs, remains largely unaffordable and out of reach for Indigenous Batwa people and rural residents.
- Mongabay visited villages off the power grid in the DRC’s Tanganyika province, where Indigenous people and local communities aspire to have access to electricity and embrace a new way of life.
- As electricity remains out of reach, despite a handful of solar panels, most rely on cutting wood from forests and savannah for firewood and charcoal — spiking deforestation in the region.
- Researchers and environmentalists suggest government subsidies, favorable taxes, and investing in cheaper Chinese solar panels to make solar energy more accessible and affordable for Indigenous and rural communities. Hydropower dams, say some, also offer cheaper long-term solutions but can come with environmental costs.
Small-scale fishers’ role in feeding the planet goes overlooked: Study
- A new study found that small-scale fishing accounts for at least 40% of catch worldwide and provides employment for 60 million people, more than a third of whom are women.
- Small-scale fishing could provide a significant proportion of the micronutrient intake for the 2.3 billion people on Earth who live near coastlines or inland bodies of water, the study found.
- More than 60% of small-scale fishing catch in the studied countries came from places where small-scale fishers had no formal rights to participate in management and decision-making processes.
- “We wanted to have a paper that provided key findings at the global level for each of these dimensions, so that it will be clear for governments that small-scale fishing cannot continue to be overlooked in terms of policymaking,” one of the study authors told Mongabay.
‘Truffle dogs’ help sniff out two new truffle species
Two dogs specially trained to sniff out truffles have helped researchers identify two new-to-science truffle species in the U.S., according to a recent study. Truffles, synonymous with luxury fine dining, are the fruiting bodies of fungi belonging to the genus Tuber, which grow underground in a symbiotic relationship with the roots of trees like oak, […]
Mammals, birds in Vietnam’s rare coastal forests revealed by camera traps
- A new camera-trapping study has found several rare and threatened species in Vietnam’s Nui Chua National Park, home to one of mainland Southeast Asia’s last remnants of dry coastal forest.
- However, the findings also indicate intense pressure on wildlife populations within the reserve from habitat fragmentation and snaring.
- The study found a relatively high diversity of species in transitional habitats between different types of forest, indicating a need for more nuanced conservation planning to target localized measures, the authors say.
- The findings reaffirm the importance of Vietnam’s dry coastal forests for biodiversity and the need for strengthened protection to reduce pressure on wildlife from snaring and habitat degradation.
Singing lemurs found to be dropping beats just like King Julien
The indri, a critically endangered lemur only found in Madagascar’s rainforest, might hold clues about the human knack for musicality, a Mongabay video explains. Indris (Indri indri) are one of the largest living lemurs, and among the few primates that sing. Researchers studied 15 years’ worth of recorded indri songs, and found that these songs […]
AI can already identify species in photos. Can it extract even more data?
- Researchers have developed a new data set and evaluation tool to gauge how artificial intelligence models can analyze wildlife images beyond just identifying species.
- The tool, named INQUIRE, found that AI models didn’t perform well when asked to analyze more nuanced details from images captured by citizen scientists.
- The team that developed the tool, however, said that vision-language models have the potential to extract more data from wildlife photos, if trained extensively in the future.
Researchers find microplastics for the first time in the Finnish Sámi waters
- Scientists and Indigenous Skolt Sámi knowledge holders have detected microplastics in the lakes and rivers that the Indigenous Sámi communities have used for generations.
- The concentration of microplastics was small, researchers found, but it was still higher than the quantity expected, given that the area is thought to be pristine.
- The average size of the microplastics was 100 micrometers and concentrations ranged from 45 to 423 microplastic particles per cubic meter.
- While the source of the microplastics is unknown, researchers say one of the sources could be from the transboundary pollution accumulated in fish that come from the ocean to the freshwaters for spawning.
Study highlights effects of habitat fragmentation on Sri Lankan specialist birds
- A research study focusing on the endemic brown-capped babbler (Pellorneum fuscocapillus) and Tickell’s blue flycatcher (Cyornis tickelliae) shows that forest specialist birds fail to return to disturbed lands, and even forest generalists tend to avoid these areas, causing delays in their return.
- Researchers employed a method called “experimental translocation” to understand how species interact with new environments by releasing the birds at various distances in different habitats, monitoring whether the birds returned to their original locations.
- A global review by the same researchers identifies 32 instances in which the experimental translocation method was used to study birds worldwide. The Sri Lankan experiment is the first of its kind in South Asia.
- The research highlights that even highly mobile creatures like birds are affected by forest fragmentation, underscoring that the impact can be even worse for less mobile creatures.
Researchers make the case for shift from economic growth to human well-being within planetary limits
- New research concludes that humanity would benefit more if it aims for ecological sustainability and stays within the limits of what Earth can provide, rather than pursuing relentless growth.
- The success of capitalism depends on the push for growth, which requires the use of resources and energy, and comes at the cost of ecological damage.
- Economists have proposed alternatives that focus on staying within a set of planetary boundaries that define the safe operating space for humanity.
- The review, published in the journal Lancet Planetary Health, draws on more than 200 resources from the scientific literature.
Underwater volcano in Barents Sea reveals diverse marine life, study finds

What the study says: In 2023, scientists from UiT The Arctic University of Norway discovered the […]
How to tell if mangrove restoration is working? Listen to the birds
- Mangrove restoration is often motivated by the desire to bring back biodiversity to degraded coastlines, but it’s difficult to know exactly when that objective has been achieved.
- Researchers in Malaysia say that monitoring mangrove-dwelling bird communities using bioacoustics could be a game-changer for managers tracking mangrove ecosystem recovery.
- Bioacoustics, the use of audio recording devices to listen to animals in their natural habitats, is increasingly being used as a rapid and relatively cost-effective way of measuring ecosystem health.
- The new study found bird species richness increases across a range of mangrove forest characteristics, including greater canopy cover, tree height and ground cover, indicating birds could serve as useful indicators of mangrove health.
As global genetic diversity declines, conservation efforts offer some hope
Genetic diversity within many species is declining globally, according to a recently published study. “Any threat that reduces the size of a population, or which causes a larger population to become fragmented into two or more smaller populations, can cause a loss of genetic diversity,” lead researcher Catherine Grueber, from the Conservation Genetics Specialist Group […]
Lures that attract seed-dispersing bats could aid tropical reforestation
- Fruit-eating bats play an important role in maintaining forest health by being seed dispersers. For decades, researchers have explored ways to harness this capacity as a reforestation tool.
- One method has been to use fruit-derived essential oils to attract bats to deforested sites, where their seed-loaded feces may help stimulate regrowth.
- A recently published study goes one step further by using chemical compounds derived from those oils to attract bats. This new way of making lures could prove less expensive, so cheaper to scale up. But before such reforestation tools are widely implemented, more research and evidence are required.
- Long-term testing is needed to show that bat lures, and the seed dispersal they bring, markedly aid regrowth — a complex process that can fail due to seed competition with grasses and seed predation. Some experts say planted tree patches are better attractants; others say combined methods may work best.
Uganda’s tree-climbing lions grow scarce amid nationwide decline of the big cat
- Lion populations in six protected areas across Uganda have declined markedly over the past decade, a recent survey shows.
- The researchers attribute this decline, in some cases of nearly 50%, to poisoning of the big cats by livestock farmers, snaring by poachers, and habitat loss.
- They’ve called for greater community engagement in conservation efforts, including monitoring lion populations; for their survey, they trained more than 100 lodge guides, trophy hunters, university students and government rangers to help with monitoring.
- Another potential solution could be the adoption of AI to boost monitoring, not just of lions but also other large African carnivores, and understanding of the challenges faced by animals and people across a landscape.
Do cheetahs scavenge? Yes, research says, but also not really
- Recently published research finds that cheetahs aren’t above scavenging other predators’ kills, contrary to the conventional wisdom that they only eat what they kill.
- Direct observations and by-catch data from carnivore research projects in three locations in South Africa and Malawi were used to gather information on cheetah scavenging.
- The researchers say that understanding these behavioral shifts is crucial for cheetah conservation, as successful reintroduction efforts depend on the ability of cheetahs to adapt to new environments and food acquisition strategies.
- However, other cheetah experts question how common this phenomenon is, given that the researchers only recorded three scavenging events between 2019 and 2023.
Scientists are tracking global wildlife’s contributions to humanity
- New research assesses in detail the contributions of wildlife to people.
- Humanity relies on an array of ecosystem services for well-being and survival, but the provision of these services rely not just on vegetation but also the wild animals that inhabit the same ecosystems.
- They found that vertebrate wildlife on land and in freshwater and marine environments support 12 of the 18 categories of nature’s contributions to people set forth by the U.N.’s Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services.
- The authors say that accounting for wildlife along with measures of ecosystems such as vegetation cover will provide a more complete picture of their health and help guide decision-making aiming to ensure that those ecosystems continue to provide critical services to people.
A venomous Australian spider turns out to be 3 species, not 1
The Sydney funnel-web spider, a highly venomous arachnid found crawling in and around Australia’s most populous city, was long thought to be a single species. But it’s actually three different species, a new study has found. One of these, called “Big Boy” for its unusually large size, is new to science. “You would think we […]
‘LIFE’ scores map out where habitat loss for crops drives extinction
- Altering natural habitats for agriculture is the single biggest driver of extinctions.
- Land conversion is contributing to what scientists call Earth’s sixth mass extinction.
- Now, new maps link the conversion of landscapes to the risk of extinction for species; they also help identify places where restoration could increase the probability that species will survive.
- The tool works accurately on areas of land ranging from 0.5-1,000 km² (0.2-386 mi²), and could be used by consumers and conservation groups to identify key areas to prioritize for conservation or restoration.
Smart tags reveal migratory bats are storm-front surfers
What’s new: Some bats, like birds, migrate long distances. But these long-distance bat migrations have been somewhat of a mystery to researchers, especially since only a few species embark on them. Now, in a new study, researchers have mapped the odyssey of common noctule bats (Nyctalus noctula) using innovative tiny trackers. And the results have […]

Bonobo numbers in DRC park stable, but signs of decline appear
Bonobo populations in the Democratic Republic of Congo’s Salonga National Park remained steady between 2002 and 2018, but there are worrying signals of decline, a recent study has found. For decades, Salonga has been known to host the largest known population of bonobos (Pan paniscus), an endangered great ape found only in the DRC. However, […]
New evidence spells massive trouble for world’s sharks, rays and chimaeras
- A third of the world’s sharks, rays and chimaeras are threatened with extinction, and their numbers have dwindled since 1970, finds a new IUCN report and a study.
- Overfishing is the biggest threat to these marine fish, halving their populations in five decades, followed by the international trade in shark parts, habitat degradation and pollution.
- Scientists call for immediate actions to prevent extinction, regulate trade and manage shark fisheries to promote sustainability.

Photos: Top new species from 2024
- Scientists described numerous new species this past year, from the world’s smallest otter in India to a fanged hedgehog from Southeast Asia, tree-dwelling frogs in Madagascar, and a new family of African plants.
- Experts estimate that fewer than 20% of Earth’s species have been documented by Western science, with potentially millions more awaiting discovery.
- Although such species may be new to science, many are already known to — and used by — local and Indigenous peoples, who often have given them traditional names.
- Upon discovery, many new species are assessed as threatened with extinction, highlighting the urgent need for conservation efforts.
Amazon’s Boiling River gives scientists a window into the rainforest’s future
- Scientists studying Peru’s Boiling River found 11% fewer tree species for every 1°C (1.8°F) increase in temperature, offering insights into how climate change might affect the Amazon Rainforest.
- The research team discovered that hotter areas not only had fewer species overall but were dominated by heat-tolerant trees that typically grow in the warmest parts of South America.
- The study site is protected by Indigenous Asháninka people as sacred land, but the forest still faces threats from nearby deforestation and fires, reflecting broader challenges across the Amazon.
- The Amazon is experiencing climate pressures, with fire-affected areas in the Brazilian Amazon increasing 18-fold in September 2024, covering a combined area nearly the size of the Netherlands.
Electrochemical removal of ocean CO2 offers potential — and concerns
- Stripping seawater of carbon dioxide via electrochemical processes — thereby prompting oceans to draw down more greenhouse gas from the atmosphere — is a geoengineering approach under consideration for largescale CO2 removal. Several startups and existing companies are planning projects at various scales.
- Once removed from seawater, captured carbon dioxide can be stored geologically or used commercially by industry. Another electrochemical method returns alkaline seawater to the oceans, causing increased carbon dioxide absorption over time.
- In theory, these techniques could aid in carbon emission storage. But experts warn that as some companies rush to commercialize the tech and sell carbon credits, significant knowledge gaps remain, with potential ecological harm needing to be determined.
- Achieving the scale required to make a dent in climate change would require deploying huge numbers of electrochemical plants globally — a costly and environmentally risky scenario deemed unfeasible by some. One problem: the harm posed by scale-up isn’t easy to assess with modeling and small-scale projects.
As lithium mining bleeds Atacama salt flat dry, Indigenous communities hit back
- The Council of Atacameño Peoples filed a complaint in October 2024 against lithium mining companies operating in Chile’s Atacama salt flat, accusing them of causing the land to sink around their extraction wells.
- The complaint was based on findings from a study published in July that revealed portions of the salt flat are subsiding by up to 2 centimeters, or nearly an inch, per year.
- Scientists warn that one of the main consequences could be the loss of the aquifer’s storage capacity.
- They also point out that since the salt flat lies on a tectonic fault, the subsidence could spread further, including to two protected areas in the region that are home to flamingos and other rare wildlife.
Counting Crows (and more) for Audubon’s Christmas bird count

The annual bird census collects valuable data that scientists use to track the health and […]
From Bhutan to Nigeria & Kenya, women endure climate change differently than men
- Research shows that globally, women and girls suffer greater effects of climate change and environmental disasters than men; at the same time, women environmental journalists often face greater obstacles on the job, and women’s voices are often missing from stories about climate change.
- Three recent Mongabay fellows, all women, report on specific examples from their home countries (Bhutan, Nigeria, Kenya) in which women disproportionately experience the effects of climate change and extreme weather.
- In all three examples, women exhibit a perseverance that ensures their own and their families’ survival — and sometimes aids their own independence and resourcefulness.
For ecological restoration, evidence-based standards deliver better outcomes (commentary)
- The UN Decade on Ecosystem Restoration has triggered a global movement to rally individual action, financial investment, and political backing to prevent, halt and reverse the loss of nature.
- Evidence-based standards can help meet restoration targets and improve general compliance with laws and regulations while delivering social, environmental and economic net gain for people and nature.
- “As we near the halfway point of the UN Decade on Ecosystem Restoration [the] global application of effective restoration through the use of standards provides a path forward that can help slow climate change and recover ecosystem processes and biodiversity for the future of life on Earth,” a new op-ed argues.
- This article is a commentary. The views expressed are those of the authors, not necessarily Mongabay.
Unlike: Brazil Facebook groups give poachers safe space to flex their kills
- A new study shows how openly poachers in Brazil are sharing content of dead wildlife, including threatened and protected species, on Facebook.
- It found 2,000 records of poaching on Brazilian Facebook groups between 2018 and 2020, amounting to 4,658 animals from 157 species from all over the country.
- Data suggest there were trophy hunts, meant only to show off hunting hauls rather than being done for subsistence or a consequence of human-wildlife conflict.
- The study highlights the impunity for environmental crimes and the easy dissemination of content related to illegal practices on social media networks in Brazil.
New frog species show how geology shapes Amazon’s biodiversity
- DNA testing of two new-to-science frog species has shown they share a common ancestor — a species that lived 55 million years ago in the mountains of what is today Brazil’s Amazonas state.
- The multidisciplinary study drew together biologists and geologists to map how geological changes in the mountain range shaped not just its geography but also the diversity of species in the region.
- The two endemic species were collected on two separate peaks — Neblina and Imeri — and their discovery has led to further understanding of the origins and evolution of biodiversity in the Amazon.
- Another expedition to the Tulu-Tuloi Range, located 200 kilometers (120 miles) from Imeri, is scheduled for 2025.
Next-gen geothermal offers circular promise, but needs care and caution
- Enhanced geothermal systems (EGS) and other next-generation geothermal tech show promise as a relatively clean, reliable renewable energy source for a post-fossil fuels future.
- Next-gen geothermal uses a variety of engineering techniques, including hydraulic fracturing borrowed from the oil and gas drilling industry, to create conditions for successful subsurface energy production beyond traditional locations, such as hot springs.
- Enhanced geothermal’s promise of a reliable source of power is huge around the globe, but so far has barely been tapped, say experts. Companies are starting to develop commercial-scale projects, aiming to harness this potential.
- But next-gen geothermal is not without risk. There are concerns, for example, that this tech can induce seismicity. In the past decade, earthquakes shut down two EGS projects in South Korea and Switzerland. Yet, experts say this concern and other environmental impacts, such as pollution, can be controlled and mitigated.
Greater Mekong serves up 234 new species in a year, from fanged hedgehog to diva viper
- Researchers and local nature enthusiasts described 234 new-to-science species across the Greater Mekong region in 2023.
- Among the new assortment of critters are sweet-smelling plants, glamorous snakes, a dragon lizard, a psychedelic-orange crocodile newt, and several new mammals, including a mole shrew and a fanged hedgehog.
- The Greater Mekong is a fast-developing region of Southeast Asia, characterized by intensive agriculture, internationally significant inland fisheries and rapid urban expansion.
- As such, the newly described species and their habitats are under pressure from multiple threats, not least from the illegal wildlife trade that also flourishes in the region. Experts say consistent and concerted action is required to secure their future.
Foreign investor lawsuits impede Honduras human rights & environment protections
- Foreign investors in Honduras have “extraordinary privileges,” allowing them to sue the government for reforms that affect their investments, hindering public interest legislation, a recent report has found.
- Honduras faces billions of dollars in lawsuits from corporations, many tied to controversial investments made after the 2009 coup, creating a deterrent effect on the government’s ability to make sovereign decisions and making it the second-most-sued country in Latin America over the period of 2023 to August 2024, after Mexico.
- Some local communities in Honduras are divided over foreign investment projects, with several expressing resistance due to concerns about their impact on the environment and land rights.
- Honduras’ recent energy reforms and mining bans are facing backlash and legal challenges, as foreign corporations resist changes aimed at protecting natural resources and human rights.
Philippines’ ‘extraordinary’ typhoon season was climate-fueled: Scientists
From late October to November this year, six consecutive tropical cyclones battered the Philippines, affecting 30 million people. Data analyses from two separate organizations now show they were intensified by human-induced climate change.

Brazil natural landscape degradation drives toxic metal buildup in bats
- Bats play a crucial role in tropical regions as pollinators, seed dispersers and agricultural pest controllers. But they are exposed to a wide range of threats, pollution among them.
- Two recent papers show how natural landscape transformation and degradation, due to pasture and crop monoculture creation and mining in Brazil’s Atlantic Forest, can increase bioaccumulation of toxins and heavy metals in bat populations, leading to potential health impacts.
- Over time, this toxic accumulation could increase the likelihood of local bat extinctions and the loss of vital ecosystem services. The toxic contamination of these landscapes also poses a concern for human health, researchers say.
- These findings are likely applicable to bats living in other highly disturbed tropical habitats around the world, researchers say.
After historic 2024 coral bleaching, hope remains for Mesoamerican Reef
- The Mesoamerican Reef, the longest barrier reef in the Western Hemisphere, stretches 1,000 kilometers (620 miles) along the Caribbean coasts of Mexico, Belize, Guatemala and Honduras.
- The latest instalment of the Mesoamerican Reef Report Card, a periodic health assessment, finds that in 2024, the worst coral bleaching event on record reduced the reef’s coral cover.
- Although the overall health of the Mesoamerican Reef remains “poor,” according to the report, its health actually improved for the first time in five years.
- The report attributes this positive development to an increase in fish populations due to effective enforcement of fisheries rules by regional authorities.
Pesticide exposure drives up rural women’s cancer risk in Brazil farming belt
- A study has found that women exposed to pesticides during farm work in Brazil’s Paraná state have a 60% higher risk of developing breast cancer, and a 220% higher risk of metastasis.
- While they don’t typically spray the pesticides, these women are responsible for cleaning the equipment and clothing used to do it, during which they rarely wear personal protective equipment.
- The study found glyphosate, atrazine and 2,4-D in urine samples from rural women; health and regulatory agencies consider these three pesticides as possibly or probably carcinogenic.
- Brazil has one of the most permissive pesticide markets in the world, where levels of exposure to chemicals like glyphosate are several times higher than in more strictly regulated jurisdictions such as the European Union.
Clouded leopard sighting raises questions about conservation and research in Bangladesh
- Clouded leopards occur in some South and Southeast Asian countries, but have fast been losing their habitat and, in 2021, IUCN declared the carnivore a vulnerable species.
- In Bangladesh, where there is no official record of the species, wildlife researchers studying other wildlife recently spotted clouded leopards in their camera trap footage, raising hope for their habitat conservation.
- Researchers have expressed concern about the lack of intensive research and conservation strategies for endangered species in Bangladesh.
Climate funds barely reaching small-scale farmers, report finds

Climate financing should come from oil and gas ‘super’ profits, study says
- Oil and gas companies have the ability to become a significant source of climate financing, a new study in Climate Policy argues.
- The study looked at oil and gas profits from 2022, when the Russian invasion of Ukraine spiked energy prices across the globe, boosting realized companies’ earnings by 65%, or around $495 billion.
- If governments had imposed an additional 30% tax on the profits of private oil and gas companies, it would have raised $147 billion, the study said.
- Climate financing was the focus of the COP 29 climate conference, which only managed to come up with $300 billion in annual support for developing countries.
No deal to curb plastic production as latest negotiations fizzle
Negotiations for a global plastics treaty ended on Dec. 2, without a consensus on how to curb plastic pollution despite its increasing negative impacts on people and nature. The fifth meeting of the U.N. Environment Programme’s Intergovernmental Negotiating Committee (INC-5) in Busan, South Korea was expected to produce a legally binding global treaty covering the […]
Teamwork makes the dream work for orcas hunting world’s biggest shark
Orcas, or killer whales, are the apex predator in the ocean when they work together. A new study documents how a pod of orcas is able to hunt and kill the largest fish in the world, the whale shark (Rhincodon typus), which can be twice the size of an individual orca (Orcinus orca), though the […]
Study finds rare wolf feeding on nectar and spreading pollen
What’s new: One of the world’s rarest carnivores, the Ethiopian wolf, enjoys snacking on flower nectar, a new study has found. This wolf is, in fact, the first large carnivore documented feeding on nectar and leaving with a pollen-laden nose and mouth, possibly making it the only large meat-eating predator that also serves as a […]
Camera traps, drones meant for wildlife can ‘spy’ on women: Study
Technologies like camera traps and drones have made monitoring wildlife in forests easier than ever. However, a new study has found that in a protected area in northern India, these devices also end up watching and harassing women who use those forest spaces. “These findings have caused quite a stir amongst the conservation community,” Chris […]
Citizen scientists can boost IUCN species assessments, but need better guidance from ecologists
- More than 100,000 Australian citizen scientists are contributing crucial biodiversity data about species at risk, helping improve conservation efforts in ways that can enhance IUCN Red List decisions.
- Citizen science projects like Fungimap and FrogID showcase how such observations have influenced threat assessments and conservation outcomes.
- Researchers stress the need for clear goals, standardized protocols, and expert oversight to maximize the impact of citizen science.
Researcher discovers new role played by manatees, ‘the gardeners of the Amazon’
- According to a new study, the Amazonian manatee is a seed disperser; a researcher found germinating grasses in its feces.
- The discovery was made in Lake Amanã, in the Amazon, where 96 samples of manatee feces were collected; surprisingly, they contained 556 intact seeds.
- Manatees eat 40 kilograms (88 pounds) of aquatic plants a day and migrate long distances. This finding shows that the manatee is a crucial vector for dispersing seeds between fertile areas such as floodplains and nutrient-poor areas such as the swamp forests known as igapós; this activity enhances biodiversity in Amazonian environments, especially in times of climate change and environmental degradation.
- Despite its vital ecological function, the manatee is listed as vulnerable to extinction; Illegal hunting, facilitated by periods of extreme drought, is one of the main threats, along with climate change, which affects both their diet and their migratory routes.
‘Old’ animals offer wisdom and stability, need protection: Study
In many animal societies, elderly individuals are critical contributors to their species’ survival, a new study has found. That’s why wildlife conservation must account for older animals, researchers say. Keller Kopf, lead author and ecologist at Charles Darwin University, Australia, told Mongabay he wanted to counter the idea that “getting old is always a bad […]
Overuse of antibiotics in Bangladesh aquaculture raises health concerns
- A recent study in Bangladesh reveals high rates of antibiotic resistance in pabda fish (Ompok pabda) bred by farmers through aquaculture.
- Consumption of antibiotic-resistant pabda fish may lead to the development of antibiotic resistance in humans as it exposes the food chain to multi-drug resistant (MDR) bacteria.
- Pabda aquaculture in Bangladesh produces around 20,000 metric tons annually, some of which is exported.
- Researchers are advocating educating farmers on the correct usage of antibiotics with the intervention of fisheries experts.
Slender-billed curlew, a bird last photographed in 1995, is likely extinct
For decades, the slender-billed curlew, a grayish-brown migratory wetland bird with a long, arched bill, has evaded detection, prompting speculation about whether the species is still out there. Now, a new study has confirmed that the species is indeed most likely extinct. “Speaking personally it’s a source of deep sadness,” Geoff Hilton, conservation scientist at […]
Five-year rainforest tech competition culminates with four winners

- The five-year XPRIZE Rainforest competition was launched in 2019 to identify solutions to automate rainforest monitoring.
Camera traps reveal little-known Sumatran tiger forests need better protection
- A new camera-trapping study in Indonesia’s Aceh province has identified an ample but struggling population of Sumatran tigers, lending fresh urgency to calls from conservationists for greater protection efforts in the critically endangered subspecies’ northernmost stronghold forests.
- The study focused on the Ulu Masen Ecosystem, an expanse of unprotected and little-studied forest connected to the better-known Leuser Ecosystem, the only place on Earth that houses rhinos, tigers, elephants and orangutans.
- The big cat population and its prey likely contend with intense poaching pressure, the study concludes; their forest home is also under threat from development pressure, illegal logging, rampant mining and agricultural encroachment.
- As a key part of the Leuser–Ulu Masen Tiger Conservation Landscape, experts say Ulu Masen merits more conservation focus to protect the tigers, their prey populations and their habitats.
‘Scratching the surface’ of Nepal butterfly research: Interview with Sanej Suwal
- With 692 identified species, including more than two dozen endemic, Nepal is an important habitat for butterflies. However, research is in its infancy due to insufficient funding, limited public interest and a lack of cultural emphasis on butterfly conservation.
- Sanej Suwal is one of a handful of researchers dedicated to butterfly research in Nepal, balancing species studies with public awareness initiatives. He organized Nepal’s first Big Butterfly Count, a citizen science initiative.
- Butterflies in Nepal likely face threats from climate change, habitat loss and urbanization. Despite their importance, butterfly research struggles with minimal funding and institutional recognition, requiring more researchers and global support to expand knowledge and conservation efforts.
Easy to catch, yet little known: Meet the Chinese mountain cat
- The Chinese mountain cat (Felis bieti) is a little-known felid found only on the eastern edge of the Qinghai-Tibet Plateau, in northwestern China.
- The species was first photographed in the wild in 2007, and until recently, very little has been known about its distribution and basic ecology.
- Researchers collected vital data on an active Chinese mountain cat den in 2018, while a recent study in Menyuan county, Qinghai province, managed to GPS-collar Chinese mountain cats for the first time.
- Recent genetic research highlights the growing threat posed by hybridization with domestic cats.
Controversial study finds cattle and wildlife can co-exist in Kenya’s Maasai Mara
A new study conducted in Kenya is challenging the conventional wisdom that cattle are inherently bad for wildlife, reports Mongabay’s Ashoka Mukpo. In contrast to previous research, the recent study found that a limited number of cattle — grazing illegally in one portion of Kenya’s Maasai Mara National Reserve (MMNR) — had a negligible effect […]
Shipping emissions reduction sheds light on marine cloud geoengineering
- Unprecedented marine heat waves in the North Atlantic have been driven in part by a recent drop in shipping emissions, leading to a reduction in highly reflective marine clouds that had previously masked some of the warming from humanity’s greenhouse gas emissions, studies find.
- New limits on sulfur dioxide emissions from shipping, introduced by the International Maritime Organization in 2020, created an inadvertent “natural experiment” that is helping to improve models of the interaction between atmospheric aerosols, clouds and climate.
- The sulfur dioxide emissions reduction also provides the clearest test to date of marine cloud brightening (MCB) — a controversial geoengineering approach proposed to mitigate climate change. It shows that to be effective and avoid a dangerous termination shock, MCB would need to be continuous and sustained.
- Reducing atmospheric aerosol pollution has major benefits for human health, but will also inevitably lead to an unmasking of more dangerous climate warming. This means that improvements in air quality must simultaneously be coupled with decarbonization, experts say.
New ‘Cali Fund’ plans to make companies pay for benefiting from nature
A new global fund for conservation seeks to make corporations share part of their profits of benefiting from using genetic data from animals, plants or microorganisms in nature. Named the Cali Fund, the new finance mechanism was born out of the recently concluded United Nations Convention on Biological Diversity summit, or COP16, held in Cali, […]
African elephants declining — but some areas show promise
Across the African continent, elephant populations have largely declined over the past several decades, but some areas show hopeful signs of recovery, according to a new study. Researchers have monitored the numbers of forest and savanna elephants (Loxodonta cyclotis, L. africana) in different parts of Africa since the 1960s. However, few studies have compiled all […]
Long-running tropical forest research stalls amid Venezuelan crisis
- Venezuela’s economic, institutional and economic collapse has put at risk a long-standing forest plot research network.
- With highly biodiverse forests covering about half of Venezuela’s total area, the country has some of the longest-running forest monitoring projects in the tropics, which represented a pioneering effort in understanding old-growth forest dynamics in the Amazon Basin.
- Falling budgets, a humanitarian crisis affecting personnel and logistics, the rise of armed gangs, and encroachment of logging and agriculture are some of the key factors threatening to halt research in the field.
- 2016 was the last year with still significant measurements in the field; today, projects lack permits to apply for international funding, but scientists continue to advocate for keeping efforts ongoing.
Gibbons found to perform dance routines akin to ‘the robot,’ but why?
- Scientists have documented scores of animal species that perform elaborate dance displays for a variety of purposes: from courting cranes to pair-bonding penguins and waggle-dancing honeybees.
- New research and video evidence show that adult female crested gibbons also perform captivating dances in both captive and wild settings.
- The funky sequences of rump, arm and leg twitches have in the past been likened to the human “robot dance” and hypothesized as fulfilling a role in gibbon courtship.
- Experts say improved understanding of the dance brings new insight into small ape cognition and social structures, which will ultimately help conservationists better design and implement interventions to protect them.
Animals consume alcohol more often than previously known: Study
What’s new: Humans know a thing or two about drinking alcohol, but accounts of animals turning to booze have often been discounted as accidental, unnatural or rare. Researchers now argue in a new study that animals drinking alcohol, or more specifically ethanol, might be more commonplace in the natural world than previously thought. “We’re moving […]

Atmospheric methane removal: A promising but challenging climate solution
- Methane is currently responsible for about one-third of global warming. This greenhouse gas is about 80 times more potent than carbon dioxide in terms of its ability to heat up the climate system, though methane molecules only persist in the atmosphere for seven to 12 years before breaking down.
- Methane emissions are a major cause for concern, as they’ve been increasing at record speeds the past five years. At least two-thirds of annual methane emissions now come from human activities, including livestock, agriculture, fossil fuels, and landfills and other waste. Climate change is also increasing methane releases.
- Removing atmospheric methane is a tempting prospect as a climate change-curbing strategy. Multiple geoengineering approaches are being considered, but research remains limited and largely theoretical, while environmental impacts largely remain unknown and underexplored.
- Researchers say methane removal technologies, such as the iron salt method, should be investigated to break down atmospheric methane molecules. But scientists interviewed for this story repeatedly emphasized the most urgent need is to simultaneously make rapid deep cuts to human-caused methane emissions.
Forest fires outside tropics drove 60% CO2 surge since 2001: Study
Global carbon dioxide emissions from forest fires have soared by 60% since 2001, driven largely by the burning of forests outside the tropics, according to a new study. There are now, in fact, more emissions from forests located in higher northern latitudes compared to tropical forests, the researchers found. In some areas, such as the […]
Mountain highland bats lack data, face climate threats: Study
Bats in mountainous regions are facing more threats and lack of data compared with their lowland counterparts, a recent study showed.

Mining drove 1.4m hectares of forest loss in last 2 decades: Report
Global mining activity is increasingly destroying forests, including protected areas, according to a recent analysis. Between 2001 and 2020, nearly 1.4 million hectares (3.5 million acres) of tree cover, an area a third the size of Denmark, was lost from mining-related activity, the analysis from the World Resources Institute (WRI) found. The associated greenhouse gas […]
Study finds bonobos more diverse, and more vulnerable, than previously thought
- Recently published research finds that bonobos show a much deeper degree of genetic diversity than previously thought, with the species split into three distinct subgroups that diverged tens of thousands of years ago.
- The study is based on a detailed analysis of the genomes of 30 wild-born captive bonobos, cross-referenced with more limited data from 136 wild bonobos.
- Separation into three genetically isolated groups means that each group is more vulnerable than a single unified population would be, and that loss of any of these groups would result in a significant loss of the species’ genetic diversity.
Exposure to slow-moving landslides increases with migration: Study
A growing number of displaced people are settling in mountain regions prone to slow-moving landslides, those that move between 1 millimeter (.04 inches) and 3 meters (9.8 feet) per year. A new study offers a global assessment of how the pressures of human settlement increase exposure to such landslides. As people migrate from rural to […]
Karachi expected to receive 2.3 million climate migrants by 2050: Report

According to a recent report, only Dhaka, Bangladesh, is expected to receive more migrants. If the world fails to meet the Paris Agreement target to […]
Canopy bridges serve a lifeline for Sumatra’s tree-dwelling primates
- An NGO is working with local authorities in Indonesia’s North Sumatra province to build canopy bridges for primates to safely cross roads that fragment their forest habitats.
- Pakpak Bharat district has seen rapid growth of new roads to improve communities’ access to schools and hospitals, with the trade-off being that many of these roads disrupt wildlife connectivity.
- The bridges, designed to meet the needs of different species, have been used by various wildlife, though not yet the critically endangered orangutans that the designers had in mind, and are monitored regularly through camera traps and maintenance checks.
- Conservationists highlight the bridges’ role in preventing inbreeding among isolated populations and sustaining the ecosystem’s biodiversity, with hopes to expand the initiative across Sumatra.
Calls for caution as enhanced rock weathering shows carbon capture promise
- Natural rock weathering is a fundamental part of Earth’s carbon cycle but occurs over thousands of years. Enhancing this cycle by spreading fine volcanic rock on agricultural land is a form of geoengineering that could speed up this process and permanently lock away carbon dioxide within decades.
- Startups and research programs are underway across the globe to explore the effectiveness and risks of this climate solution. Spreading rocks such as basalt can sequester carbon and benefit soils, with some studies showing crop yield increases.
- If scaled up, enhanced rock weathering could store gigaton levels of carbon in the future, according to early research. But myriad challenges and uncertainties remain, not least of which is how to accurately calculate and verify how much carbon is being stored, and for how long.
- Some companies are already pushing ahead with deployment, with the idea of profiting from carbon credits, but experts caution that long-term studies are needed to ensure the technique’s efficacy, sustainability and environmental safety.
Startups replace plastics with mushrooms in the seafood industry
- A handful of startups in the U.S., Europe and Asia are helping the seafood industry fight plastic pollution by creating equipment made from fungi.
- Efforts are currently focused on replacing plastic foam, a polluting component of numerous elements of the seafood supply chain, with mycelium, the root-like structure of fungi.
- A company in Maine makes mycelium-based buoys for the aquaculture industry, for example.
- Elsewhere, projects are seeking to create biodegradable mycelium-based coolers for transporting fish.
Women-led groups remain ‘severely underfunded’ for climate action: Report
Women-led Indigenous, Afro-descendant and local community grassroots organizations struggle to access global funding to fight climate change impacts due to structural barriers and stereotypes, a recent report shows. Total government aid, or official development assistance (ODA), for NGOs and women’s rights organizations declined from $891 million between 2019-2020 to $631 million between 2021-2022, according to […]
Six months after its worst floods, Rio Grande do Sul works to bounce back
- A combination of wet El Niño weather and human-induced climate change were key drivers of the worst flooding event in Brazil’s Rio Grande do Sul state earlier this year.
- The flooding affected 90% of the state and displaced more than half a million people.
- Poor land management is also responsible for the region’s vulnerability to floods, as current agricultural practices in the highlands favor runoff and reduce the soil’s ability to soak up water, with lowlands particularly exposed to high waters.
- While some scientists are still deciphering the causes and behavior of the floodwaters, other experts are working to rehabilitate farmland, tackle soil erosion, and source native seeds for ecological restoration.
Chilean Indigenous association participates in key study for lawsuit against mining
- In a unique model for Latin America, a council of Lickanantay people in northern Chile created an environmental unit made up of hydrogeologists, engineers and environmental monitors from the territory’s communities to monitor the territory.
- Their study with a national university shows that the La Brava lagoon, located on the edges of the Atacama salt flat, is fed in part by the salt flat’s brine, which makes it vulnerable to mining activities established in the heart of the salt flat.
- Findings from the study were key in a lawsuit brought by the state defense council against three mining companies for irreparable damage to the Monturaqui-Negrillar-Tilopozo aquifer, the main water source for these lagoons.
50 years of geographic insight: In interview with Jack Dangermond on Esri’s journey and the future of GIS
- The digital mapping platforms developed by Esri, including ArcGIS, have revolutionized conservation and environmental planning, management and policymaking. Esri co-founder Jack Dangermond calls geographic information systems (GIS) “a sort of intelligent nervous system for our planet at a time when humanity desperately needs one to address the environmental and humanitarian crises at hand.”
- He credits Esri’s success to a sustainable trajectory of heavy investment in R&D, not being beholden to outside investors, and providing discounted and free use of its software to environmental nonprofits.
- In this interview with Mongabay founder and CEO Rhett A. Butler, Dangermond says that technology, amid the current fractured political climate, should be employed to encourage understanding rather than dwell on divisions.
- The text of the interview has been edited for clarity and flow.
Protecting coral reefs boosts fish numbers by 10%: Study
- New research has found that the protection of coral reefs has boosted the amount of fish they harbor by around 10%.
- The study used survey data from about 2,600 reefs with varying levels of protection from overfishing.
- The team then built a statistical model to predict what would have happened if all reefs had not been protected, and the biomass, or collective weight of the resident fish, dropped by more than 10%.
- The scientists note their findings demonstrate that protections like marine protected areas are working and that greater coverage could lead to even more gains in fish biomass.
Polar bears are suffering paw injuries likely driven by the warming Arctic: Study
What’s new At least two populations of polar bears in the high Arctic are developing paw injuries, possibly because of shifting sea ice conditions in a warming environment, according to a new study. Such injuries have not been reported in these areas previously, the study’s authors write. What the study says Between 2012 and 2022, […]
New survey puts human face on pollution caused by U.S. wood pellet mills
- A new groundbreaking survey highlights the human toll from pollution and other quality of life impacts connected to those living near the forest biomass industry’s wood pellet mills in the U.S Southeast.
- Door-to-door interviews were conducted by a coalition of NGOs, with 312 households surveyed in five mostly poor, rural and minority communities located near pellet mills operated by Drax and Enviva, two of the world’s largest pellet makers.
- In four of the five newly surveyed communities, 86% of households reported at least one family member with diseases or ailments, which they say are related to, or made worse by, pellet mill pollution. 2023 research found that pellet mills emit 55 toxic pollutants that largely impact environmental justice communities.
- The wood pellet industry says the survey was not scientifically rigorous and that its members strive to control pollution and improve the local economies in communities where they work.
Researchers track koalas using innovative airborne DNA detection tool
What’s new: Researchers have successfully detected the presence of koalas and other threatened wildlife species using new tools that allow easy collection of airborne environmental DNA, according to a recent study. What the study says: It’s often difficult, time-consuming and expensive to collect data and observe threatened wildlife like koalas (Phascolarctos cinereus), small marsupials that […]
Botanical gardens play key role in biodiversity & climate conventions (commentary)
- “As world leaders and scientific institutions from across the globe gather to discuss the biodiversity crisis at COP16 and climate change at COP29 this fall, it’s critical that they do not neglect the important work that is already being done by one of the world’s key stewards of nature – botanical gardens,” a new op-ed argues.
- Botanical gardens have an important role to play in the overall effort to combat the dual climate and biodiversity crises and can offer important solutions, but they are often underutilized, despite housing a wide array of experts on plants and fungi.
- “At the rate the planet is warming, there is no time to leave their untapped potential behind,” writes the CEO of The New York Botanical Garden.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Elusive wildcats may hold the key to healthier forests in Africa
- Sarah Tossens, a Ph.D. researcher at Belgium’s University of Liège, is studying forest ecosystems in the Republic of the Congo and Cameroon to learn about the presence of leopards and golden cats and how they influence the ecosystem.
- Photographs from her camera traps have helped demonstrate where golden cats and leopards are living and where they’ve been lost, suggesting that sustainably managed logging concessions can be good habitat for these two cats — when poaching is controlled.
- Though her results are preliminary, experiments show that prey species may respond to the smell of wild cats, suggesting that animals in these forests eat fewer seeds when they think these predators are around. This finding could suggest wildcats help forests regenerate.
New study upends common belief that birds escape winter to save energy
- Scientists have found Eurasian blackbirds migrating to warmer regions in winter didn’t save more energy compared to members of the same species that stayed behind.
- A recently published study used surgically implanted biologgers to measure the birds’ heart rate and body temperature over the course of the winter.
- The study also found that migrating birds started saving energy for migration by lowering their heart rate and body temperature almost a month before their departure.
- The research raises important questions on why birds migrate if there’s no energy benefit, and where the unaccounted energy is being used instead.
Four of a kind: King cobra is a quad of species, not one, study finds
For a long time, the king cobra, the world’s largest venomous snake, was thought to be a single species. A new landmark study has concluded it’s not: the snake is actually four different species. “I feel like we created history,” study lead researcher P. Gowri Shankar, founder of the India-based Kalinga Foundation, told Mongabay by […]
Climate change and agrochemicals pose lethal combo for Amazonian fish
- A recent study evaluates the impacts on the Amazonian tambaqui fish from simultaneous exposure to a mix of pesticides and an extreme climate change scenario.
- Researchers subjected the fish to higher temperatures and higher atmospheric CO2 levels, as well as a cocktail of two pesticides, a herbicide and a fungicide, all of which are commonly used in farms throughout the Brazilian Amazon.
- The tambaqui’s capacity to metabolize the agrochemicals was found to be compromised in warmer water, and they suffered damage to their liver, nervous system and DNA.
- The study also points to the risks to food safety in the region, where fish are the main protein source: some 400 metric tons of tambaqui are eaten every year in the city of Manaus alone.
The disappearing red ghost crabs of Cox’s Bazar, a conservation crisis in Bangladesh
- Cox’s Bazar Beach in southeast Bangladesh is known for its vibrant red crab population, which creates a stunning spectacle in the early mornings and late afternoons. However, this natural wonder is now threatened by human activities and environmental degradation.
- Red ghost crabs benefit coastal ecosystems by aerating sand and improving water infiltration, and also as prey species. Their decline threatens the ecosystem health.
- Researchers say a beach management plan is crucial for their protection and restoration. Protected areas like in Kuakata have shown effectiveness in conserving ghost crabs. Raising awareness among local communities is also crucial for successful conservation efforts in Bangladesh.
As 25 Earth vital signs worsen, scientists warn of ‘irreversible climate disaster’
- Earth is inching closer to irreversible climate change according to a recent report by an international group of climate researchers and Earth System scientists.
- Tracking 35 planetary vital signs — used to gauge Earth’s response to human activities — researchers found 25 are at record risk levels, including greenhouse gas concentrations, fossil fuel consumption, rising temperatures, forest loss, and biodiversity decline.
- The authors underline the immediate need for wide-ranging climate action to rein in fossil fuel use and control emissions, alongside other measures to stave off a deepening climate crisis. “We are on the brink of an irreversible climate disaster,” they wrote.
Scientists use fake dolphin carcasses to study real dolphin strandings
Stranded dolphins can tell researchers a lot about the health of dolphin populations and potential dangers to human health. But figuring out how many wash ashore is difficult because scientists rely heavily on the public to report sightings. To better understand how and where ordinary citizens are most likely to report the beached mammals, researchers […]
West Africa’s forgotten felines endangered by conflict and research gaps
- The WAP Complex of protected areas that straddles the border region of Benin, Burkina Faso and Niger is one of West Africa’s most important protected areas and a haven for many iconic endangered species.
- Servals, caracals and African wildcats are also found in the WAP Complex, but almost nothing is known about their status, distribution, ecology or threats.
- Covert surveys of medicine markets in the region have found serval and caracal skins, though it’s not known if the skins originated within the WAP Complex.
- The presence of jihadist militants in the region severely impacts conservation and research, particularly in the Niger and Burkina Faso portions of the complex.
Climate change drives rise in rainfall, ‘Christmas typhoons’ in Philippines
The Philippines experienced an increase in “Christmas typhoons” and tropical cyclone-induced rainfall over the last couple of decades, according to the country’s latest climate report.
Climate change is turning Antarctica green, but not in a good way: study
What’s new: A recent study reveals that the icy Antarctic Peninsula, the northernmost part of mainland Antarctica, has experienced a nearly twelve-fold increase in plant cover over the last 35 years. The greening, driven primarily by the spread of mosses, has accelerated notably since 2016, researchers found. “The landscape is still almost entirely dominated by […]
Ant queens cannibalize their sick young to prevent disease outbreak
Ant queens practice a grim but effective form of childcare, eating their own sick larvae to recycle them into new, healthier eggs. A new study shows that by consuming their infected offspring, the queens protect the rest of their colonies from deadly infections while boosting their egg production with the influx of nutrients. Researchers behind […]
Controversial US marine geoengineering test delayed until next year
- The first-ever field test of ocean alkalinity enhancement in the United States was pushed back to 2025 due to shipping issues. But the geoengineering experiment has also run into public opposition from local environmentalists, commercial fishers and others.
- The test would dump sodium hydroxide (commonly called lye) off the New England coast to study its dispersal as a potential tool for sequestering CO₂.
- Opponents allege this small-scale geoengineering test could harm local wildlife, but researchers say the material will disperse within minutes.
- The scientists say they will also continue to reach out to local communities to alleviate fears over the study.
High CO2 levels are greening the world’s drylands, but is that good news?
The increased concentration of CO2 in the atmosphere since pre-industrial times isn’t just driving climate change — it’s also making much of the world’s drylands greener with increased plant growth. This is known as the CO2 fertilization effect, and politicians sometimes cite it to rhetorically downplay the negative global impacts of climate change, saying it’s […]
Ever-smarter consumer electronics push world toward environmental brink
- Semiconductor microchips are the beating heart of the digital age — processing vast, ever-growing volumes of data on our smart phones, computers and other electronic devices, and on data center servers worldwide.
- As manufacturers compete to produce the ever-smaller, more powerful electronic devices consumers want, new state-of-the-art silicon chips must be designed to handle exponentially advancing computing challenges.
- But the sourcing and manufacture of these increasingly complex silicon chips is material-, energy- and water-intensive, doing major environmental harm — producing major carbon emissions and polluting with PFAS and other toxins.
- Also, the smaller and more integrated chips become, the harder they are to recycle, creating vast sums of e-waste. Experts say governments need to ensure companies embrace environmental stewardship and circular economy standards.
Jumbo collaring effort reveals key elephant movement corridors
- Scientists and conservationists have collaborated to create what is possibly the largest database of GPS-collared elephants.
- The database contains 4 million GPS data points that were collected by collaring 300 African elephants in the Kavango-Zambezi Transfrontier Conservation Area, home to the largest population of African elephants in the world.
- Based on the movement of elephants, the team assessed the landscape to identify key areas and corridors for conservation purposes.
- The findings have already been used to identify small-scale movement corridors for elephants in Zambia.
People hugely underestimate carbon footprint of the wealthy, study shows
A recent study reveals that the majority of people, regardless of how much they earn, greatly underestimate the personal carbon footprint of the richest members of their society, while overestimating that of the poorest. This suggests that “most people, including the wealthiest, are largely unaware of the profound inequality in personal carbon footprints within their […]
Arctic sea ice hits summer minimum; Antarctic hovers at new winter lows
- The Antarctic winter sea ice maximum is on track to be the second lowest on record, at 17.15 million square km² (6.62 million mi²), close to the 2023 record low of 16.96 million km² (6.55 million mi²). Some scientists see this as anomalous. Others see it as a shift in the southern polar environment, maybe triggered by climate change.
- The Arctic summer sea ice minimum also stayed low this year, at 4.28 million km² (1.65 million mi²), making it the 7th lowest minimum in the satellite record. So far, 2012 saw the record minimum of 3.41 million km² (1.32 million mi²).
- Polar sea ice losses have global impacts. In one analysis, researchers estimated the planetary cooling effects of Arctic and Antarctic sea ice during 2016-2023 were about 20% and 12% less, respectively, than they were during 1980-1988, leading to almost 15% less cooling power for the planet.
- With about 12% declines of Arctic Ocean ice each decade, researchers predict a nearly ice-free Arctic summer by 2050, allowing more shipping through the Northwest Passage but threatening this unique polar ecosystem. Studies also show the Antarctic ice sheet to be increasingly at risk, particularly Western Antarctica.
Five times more marine fish may be at risk of extinction: study
What’s new: The number of bony marine fish species at risk of extinction could be five times higher than previously estimated by conservation scientists, a recent study suggests. What the study says: Bony fish, or teleosts, represent some 96% of the world’s marine fish species. The IUCN Red List of Threatened Species, the global reference […]
Inaugural Planetary Health Check finds ocean acidification on the brink
- A first of its kind Planetary Health Check by an international team of scientists indicates that six of nine planetary boundaries are not only transgressed, but are moving further into zones of risk. In addition, recent research shows that a seventh boundary, ocean acidification, is on the verge of transgression.
- Intensifying ocean acidification spells problems for marine life, fisheries and economies. Based on current human CO₂ emission trajectories, this boundary may be breached in a few years, say experts. Others argue this threshold may already have been crossed, with regional acidification above safe limits.
- Together, the nine planetary boundaries identify limits within which Earth systems can operate safely to maintain the planet’s habitability. Transgressing boundaries heightens risks of breaching tipping points that would bring about irreversible shifts to the planet, threatening humanity and life as we know it.
- This inaugural Planetary Health Check is the first of yearly scheduled reports on the wellbeing of Earth systems. Annual reports are now needed due to humanity’s rapid crossing of planetary boundaries, and due to the urgency of providing up to date scientific data to policymakers.
‘Dream birds’ in the mist: First photo of ‘lost’ bird in DRC mountains
- The mountainous forests of the eastern DRC are home to a strikingly beautiful bird: the yellow-crested helmetshrike.
- The species was considered lost to science until late last year, when an expedition of U.S. and DRC scientists spotted flocks of the birds gliding through the forests of the Itombwe mountains and snapped the first photo.
- Their observations will help to fill in some key knowledge gaps on this little-known species, which faces threats from habitat destruction and climate change.
Lab-grown corals resisted bleaching during Caribbean’s worst marine heat wave
- In 2023, the Caribbean Sea experienced unprecedented heat: Beginning in March, sea surface temperatures throughout the region ranged from 1°-3°C (1.8°-5.4°F) warmer than normal.
- This unprecedented heat brought the worst coral bleaching event in the Caribbean’s recorded history, bleaching 60-100% of some reefs, and killing many patches.
- A new study found that certain species of coral propagated in the lab and then outplanted to restore reefs in five countries showed few signs of bleaching despite the prolonged marine heat wave, faring better than wild corals or corals propagated from fragments.
We know how many okapi live in zoos. In the wild? It’s complicated
- The okapi, an endangered species that looks like a cross between a large antelope and a zebra, but is most closely related to the giraffe, is found only in the forests of the Democratic Republic of Congo and is considered an important cultural icon.
- The elusive ungulate faces more threats today than a decade ago, which was the last time a conservation assessment for the population was carried out.
- Armed militia groups, illegal mining, and a new trade in okapi oil for medicinal use have kept the species under threat and prevented scientists from being able to properly assess its population status.
- With scientists lacking reliable population estimates, a specialist group is now working to produce an updated conservation assessment within the next year.
Aluminum and steel vital to energy transition, but need circular solutions
- Aluminum and steel are in high demand today and increased volumes will be needed to achieve the energy transition and future infrastructure development.
- But mining, outdated production methods, and waste generation are putting significant pressures on several planetary boundaries — fueling climate change, impacting biodiversity, generating vast amounts of mining and other waste, using large quantities of water, and affecting human health.
- Moving away from a linear model of steel and aluminum production and consumption toward a closed-loop circular economy model could rein in some of these negative impacts and clean up these metals’ supply chains.
- Industry proponents note that circularity already occurs in both industries via recycling, but there is vast room for improvement to achieve circularity goals. This requires redesigning materials for longevity and reuse, modernizing manufacturing methods, and slashing primary raw material consumption.
Climate change could threaten newly described ‘shiny’ North American bees
- A recent study examining North American bee species belonging to the Lasioglossum genus has led to the describing of three previously unknown bee species from specimens collected from California, Arizona and Baja California.
- Due to their distinct metallic sheen, one was designated as Lasioglossum (Sphecodogastra) iridescens, while another was named Lasioglossum (Sphecodogastra) dilisena, derived from Sinhala, the majority-spoken language in Sri Lanka, with the word dilisena translating to “shining.”
- The third species is named Lasioglossum (Sphecodogastra) silveirai as a tribute to the late Fernando Silveira of the Federal University of Minas Gerais for his significant contribution to bee taxonomy.
- The newly described species are predominantly found in high-elevation areas in California, where climate change poses a significant threat, so scientists emphasize the importance of further research on their ecology and distribution.
Experts call for urgent action as invasive species threatens Brazil mangroves
- The Sonneratia apetala plant is native to India, Bangladesh, Sri Lanka and Myanmar, yet biologists have found hundreds of specimens permeating the mangroves in the south of Brazil.
- Researchers believe the seeds were transported on ships from China and released at the port just 2 kilometers (1.6 miles) from the mangroves, where they were carried in the currents and rapidly spread.
- Experts warn that S. apetala could have severe ecological impacts, including the loss of biodiversity as it outcompetes native plants; they also fear it might spread to other mangroves.
- Since May 2023, researchers have been advocating for the total eradication of S. apetala in Brazil. However, Brazilian authorities only announced last month that they would remove the species, and the details of how this will be done have not yet been specified.
Study highlights climate policies that actually work to reduce emissions
To meet the goals of the Paris Climate Agreement and avoid the worst outcomes of climate change, the world needs to rapidly reduce carbon emissions. Identifying effective policies to reach national climate goals has been challenging, but a new study published in Science examined 1500 climate policies implemented over the last two decades, and found […]
Billions in public funds ‘wasted’ on carbon capture projects, report finds
A handful of governments have spent nearly $30 billion in public funds on carbon capture and hydrogen projects, mostly for private fossil fuel companies, over the past 40 years, a new report from Oil Change International finds. National governments are expected to spend an additional $115 billion to $240 billion in the coming decades, the […]
Clearest picture yet of Amazon carbon density could help guide conservation
- A combination of machine-learning models and satellite readings show that the Amazon Rainforest contains 56.8 billion metric tons of aboveground carbon, or more than one and a half times what humanity emitted in 2023.
- The map is the result of an analysis of data measuring tree cover, tree height and the carbon storage of trees, and yields one of the most precise estimates to date.
- The highest carbon levels are located in the southwest Amazon — specifically southern Peru and western Brazil — and in the northeast Amazon, in countries like French Guiana and Suriname. The findings could help conservationists and policymakers choose more effective conservation strategies in the future.
- The report concluded that, as a whole, the Amazon Rainforest is still acting as a carbon sink rather than a carbon emitter, a key to keeping global temperatures below 1.5°C (2.7°F) and preventing climate change.
How the Zai farming technique is transforming soil fertility in North Cameroon
- Cameroon has 12 million hectares (30 million acres) of degraded land including 26,029 hectares (about 64,000 acres) around two national parks Bénoué and Faro in the North region.
- Large human and livestock populations, over cultivation and overgrazing, the growing demand for fuelwood supplies and poor rangeland management are at the forefront of the environmental problem of human-made desertification in northern Cameroon.
- A project called EcoNorCam, which uses an agroecology method known as the Zai technique, aims to restore the soil around the Bénoué National Park.
- Farmers adopting the Zai method have seen a boom in their yield despite the hefty work involved.
Northern elephant seals likely used sonar ‘dinner bell’ to find food
When eight young northern elephant seals suddenly began showing up at a deep-sea observatory, researchers were taken by surprise. Their repeated visits to the research site, otherwise a speck in the vast, dark ocean, wasn’t a chance occurrence, a new study reveals. The mammals were likely drawn to the area by the observatory’s sonar pulses. […]
Lack of research as contaminated Yaqui River poses health risks
- Amid a water crisis, Yaqui communities in the northwestern Mexican state of Sonora lack safe drinking water due to contamination by arsenic, salinity and heavy metals as unveiled by several studies over the years.
- The water crisis, driven by decades of overexploitation, unequal water distribution and drought, intensifies contamination, particularly affecting coastal areas with saltwater intrusion and surpassing safe limits in certain regions.
- Members of the Yaqui tribe blame mining operations and agribusiness for the contamination, but there are few studies to confirm their source.
- They argue contamination has led to diabetes and health complications among community members, as well as cultural impacts.
Successful Thai community-based hornbill conservation faces uncertain future
- As long-distance tree seed dispersers, hornbills help balance the ecology of the complex tropical forests they inhabit.
- Three decades of hornbill conservation in southern Thailand have been underpinned by efforts to transform former poachers into conservationists who are paid wages as nest guardians.
- A new study indicates that education programs in schools and villages surrounding the region’s hornbill strongholds are key to the success and long-term sustainability of the nest guardian program, which has boosted hornbill breeding success and drawn widespread support from local residents.
- Yet political unrest in the region precludes traditional avenues of conservation funding, such as ecotourism, leaving the community-based initiative threatened by a lack of long-term funding and resources.
