West Africa’s plan to save its vultures struggles to take flight
- Launched two years ago, the West African Vulture Conservation Action Plan (WAVCAP) aimed to protect the region’s dwindling vulture populations. But progress to implement it is lacking, say experts.
- Vultures are under severe threat in the region due to poisoning for belief-based use, persecution, and habitat destruction. Other raptors and bird species are under severe pressure due to this trade as well.
- Experts point to a lack of coordination, limited funding, and low priority for vulture conservation as ongoing challenges, amid an ever-growing trade in their parts that’s also impacting Central African countries.
- Urgent action is needed to avoid complete extirpation of vultures in countries like Benin and Nigeria, say experts, adding they hope that a coordination meeting in November will address these issues.
Beetle larvae trick bees into feeding and sheltering them by smelling like flowers, study finds
European Black oil beetle larva lures unsuspecting bees by manufacturing smells that mimic floral scents, new research suggests. The larva then hitches a ride on the bee to its burrow, where it eats the bee’s eggs and pollen, and develops into an adult beetle. This is the first known instance of an animal hijacking the […]
Damselfish-assisted repair of wounded corals surprises scientists
- A new study finds that a coral-associated damselfish may help hasten the healing of wounded corals.
- The research showed a 55% faster recovery rate from larger coral wounds in the presence of damselfish, and a 38% faster rate of healing for smaller wounds.
- Algae living within wounded corals exhibited decreased photosynthetic efficiency, an energy source vital to coral healing, when damselfish were absent.
- Scientists say the findings could inform conservation management plans, focusing more attention on preserving fish habitats to better protect corals.
Scientists use satellites to track whale strandings in remote places from space
- In the early 2000s, attempts to track cetaceans from space yielded only unidentifiable dark blobs; now, very high-resolution satellite imagery allows researchers to pinpoint specific whale species from orbit.
- This optical satellite technology provides access to remote parts of the world’s oceans, helping scientists establish vital baseline data on whale mortality trends, sea surface temperatures and ocean currents.
- Researchers emphasize that satellites will supplement, not replace, traditional field-work, as data quality remains vulnerable to environmental limitations, including cloud cover and heavy winds, and to satellite availability.
- Scientists are building global networks to improve consistency in data collection and are advocating for increased access to satellite data to better understand causes of whale strandings around the world.
Singapore made a crow-friendly city. Now it wants to shoot them
The resumption of a crow-shooting campaign in Singapore has revived intense debate over lethal wildlife management in the highly urbanized city-state. Government officials revived the culling program in response to public complaints about crow attacks on pedestrians and cyclists, reports contributor Robin Hicks for Mongabay. In a public statement in March announcing the resumption of […]
DNA analysis of Asiatic wild dogs scat in India reveals wild prey preference
Endangered Asiatic wild dogs in central India almost entirely eat wild prey, even where they overlap with livestock, according to a recent study. The findings show that maintaining healthy wild prey populations is key to conserving the species, reports contributor Rajeev Tyagi for Mongabay India. The study, led by the National Centre for Biological Sciences […]
Bogong moths support Australia’s alpine ecosystems, but face uncertain future
- Bogong moths are a critical resource for the many rare and wonderful species that live in the Australian Alps, but their future is far from certain.
- The IUCN classifies the bogong moth as an endangered species, but Australia, the only country where the moth is habitually found, has refused to recognize it as such, categorizing it instead as “data deficient”.
- Currently, a network of entomologists, ecologists, data scientists, First Nations peoples, and volunteers is working to address the data gaps, hoping to reapply for a national endangered species listing and identify the best strategies to protect the bogong moth.
- However, tracking a tiny creature that migrates hundreds of kilometers in the dark of night is no easy task.
Hermit crabs and cockroaches emerge as unlikely seed dispersers on a Japanese island
In the humid, coastal forests of Japan’s Ishigaki Island, near Okinawa, a parasitic plant relies on some unusual allies to spread its seeds: land hermit crabs and cockroaches, according to a recent study. The plant, fungus root (Balanophora fungosa), is non-photosynthetic, meaning it lacks chlorophyll and can’t make its own food. Instead, it grows as […]
Cougars cut deadly vehicle-deer collisions in the US by up to 76%, study shows
- When cougars are present in a landscape, roads are safer, according to a new study.
- In area where the cats were highly active, the expected number of deer-vehicle collisions fell by 76% over five years, with the probability of a collision falling by 67%.
- Researchers found that fear changes deer behavior: Rather than simply reducing deer numbers by eating them, pumas appear to create a “landscape of fear” that pushes deer away from developed areas and shifts their active hours from nighttime into daylight.
- Large carnivores, including cougars, keep fast-reproducing prey species in check, while also reducing dangerous and costly wildlife collisions — another reason why coexistence with them is important, experts say.
As Singapore culls ‘nuisance’ birds, rapid urbanization continues to fuel an avian boom
- A campaign to shoot crows has resumed in Singapore in response to a surge in public complaints about attacks, with authorities saying “pest” birds pose a public health risk and outcompete native species.
- Ecologists argue Singapore’s crow problem is human-made, with poor waste management and illegal feeding fueling a population boom.
- They criticize culling as ineffective over the long term and say it risks normalizing lethal wildlife control while undermining Singapore’s “City in Nature” vision.
- Nature groups say ongoing and planned forest clearance for public housing could lead to further increases in urban bird populations, as more favorable habitats are created, leading to “endless culling” to control bird populations.
From small cats to pangolins: Detection dogs help track elusive species
- Dogs trained to detect scat are helping conservationists detect and research hard-to-study species in South Africa’s Karoo region.
- From the black-footed cat and Temminck’s pangolin to riverine rabbits, the scat samples contain ‘nuggets of genetic data’, according to scientists.
- The research and fieldwork has also helped uncover evidence of wildlife crimes and identify habitats in need of protection from development.
Social media images lead to first recording of parasitoid wasp species in Japan
Photos of a striking, iridescent wasp posted on social media by wasp enthusiasts in Japan have led to an unexpected discovery: The images are the first record of the species in Japan. The footage also helped scientists describe a male of the species for the first time. The images and a video of the wasps […]
Scientists discover that giant octopuses were top predators of ancient oceans
Finned octopus species alive today are all small, deep-sea animals that mostly live in pitch-black darkness thousands of meters beneath the surface of the sea. But a new discovery by a team of researchers in Japan, published in April 2026, found that the ancient octopus relatives were likely gigantic predators that roamed the late Cretaceous […]
Africa’s smallest wildcat found using abandoned rodent burrows to raise kittens
Africa’s smallest wildcat uses abandoned springhare burrows to raise its kittens, according to new research. There are fewer than 10,000 black-footed cats (Felis nigripes) left in the wild and studies on these nocturnal animals are rare. To learn more about them, a team of researchers tracked five female black-footed cats (Felis nigripes) with radio collars […]
Extreme weather dampens breeding success for marine predators in Tasmania: study
- A recent study found that extreme weather events like storms, heat waves and floods can interfere with the breeding success of marine predators like seals, shearwaters and albatross that raise their young along the coasts of the Australian state of Tasmania.
- While some colonies appeared unaffected by extreme weather, others saw offspring swept away by powerful waves and storm surges, hypothermia during unusually wet episodes, and deadly overheating during periods of high temperatures.
- The researchers noted that these extremes are among many challenges seals, seabirds and other marine predators face, including pollution, disease and declining food supplies, which can also be influenced by extreme weather events.
Smithsonian ornithologist John Rappole reconsidered why birds migrate
- John Hilton Rappole helped reshape the study of bird migration by showing that migratory songbirds were established members of tropical ecosystems during winter.
- His dispersal theory argued that migration may have developed as tropical birds expanded into seasonal northern habitats, challenging a long-standing scientific explanation.
- Across five decades of fieldwork, he studied birds in the United States, Mexico, Central America, and Myanmar, and spent 20 years at the Smithsonian Conservation Biology Institute.
- Colleagues knew him as a rigorous, generous, and modest scientist who trusted sustained observation, questioned established assumptions, and revised his conclusions when the evidence required it.
How to stitch a massive wildlife corridor through the Rocky Mountains
- Across the world, roads, railways, towns and farms sever habitat, preventing wildlife from moving across the landscape. Cutting off animals’ ability to connect can limit genetic exchange and cause entire populations to decline — and ultimately, collapse.
- The Yellowstone to Yukon Conservation Initiative, or Y2Y, is trying to create a giant connected area stretching across the Rocky Mountains from the Greater Yellowstone ecosystem in the U.S. to Canada’s Yukon Territory. It will allow animals to move, meet and mate.
- Across Canada, the U.S. and the world, countries are building wildlife crossings that reconnect habitat and keep motorists safe from costly, potentially deadly collisions with animals.
How Costa Rica’s extreme climate changes the social behaviors of white-faced capuchin
- For 33 years, a research team has studied white-faced capuchin monkeys in the tropical dry forests of Costa Rica, gathering data on their complex social lives.
- A new study from the team shows that during extreme climate events, large groups of capuchins may go hungry, while smaller groups may fare better.
- Climate extremes alter the physical landscape, causing animals to change their societal behaviors. For capuchins, this means greater competition for food, heightened territorial sensitivity and fluctuating group sizes.
- While capuchins can adapt to environmental changes over time, there are limits to their resilience, as seen during the severe droughts caused by the El Niño in 2014-2016, when dwindling food sources caused capuchins to abandon societal norms in search of food.
Bill Montevecchi showed what seabirds could tell us about the sea
- Bill Montevecchi spent more than five decades showing how seabirds could reveal changes in the North Atlantic, helping establish them as indicators of ocean health, fisheries, pollution, and climate change.
- Based at Memorial University in Newfoundland, he combined field research with public communication, believing scientists had a responsibility to explain their work beyond academic journals.
- His research informed marine conservation, fisheries management, and environmental policy, while his mentorship and interdisciplinary collaborations influenced generations of seabird scientists.
- Montevecchi approached birds as sources of evidence rather than symbols, arguing that careful observation and rigorous science offered one of the clearest ways to understand a rapidly changing ocean.
Gus Mills, hyena expert and ‘the cheerful pessimist of the Kalahari’, has died
- Gus Mills spent more than four decades studying hyenas, wild dogs, cheetahs, and other African carnivores.
- After struggling in school, he found his vocation in field biology and began long-term research in the Kalahari in 1972.
- His work challenged common misconceptions about hyenas and showed the value of patient observation, public participation, and ecosystem-based management.
- Even after retiring from SANParks, he returned to the Kalahari for a six-year cheetah study that involved 7,000 hours of observation.
Beavers brought a volcanic wasteland back to life. Now it’s under threat
- Mark Smith and his family run a campsite that backs up to the North Fork Toutle River in the U.S. state of Washington, which was swamped with sediment and runoff from the 1980 eruption of Mount St. Helens.
- The fine-grained volcanic sediment smothered the waterway, making it difficult for native wildlife and vegetation to become reestablished even decades after the eruption.
- But over the past five years, the Smith family, together with natural resource experts from the Cascade Tribe, the Cascade Forest Conservancy, the Columbia Fish Recovery Group, and the Cowlitz Indian Tribe, have reintroduced beavers to the property.
- By building dams and canals, the beavers have established deeper pools and wetlands along the North Fork Toutle River, allowing native trees and fish to repopulate the area.
A win-win, animal crossings make roads safer for wildlife and people
Worldwide, roads act as both death traps and barriers for wildlife, fragmenting the landscapes animals need to survive. However, ecologists and engineers are working to “reconnect the wild” through the strategic construction of wildlife crossings. As Mongabay contributor Ben Goldfarb reports, structures, including underpasses and massive overpasses paired with roadside fencing, have proved highly effective […]
Belief-based use increasing threat to yellow-billed kite, an important African scavenger
- Yellow-billed kites are widespread across Africa. But conservationists warn that in the absence of heavily-hunted vultures, this bird is now targeted for use in belief-based rituals in West Africa.
- A survey spanning two hunting seasons in southern Benin estimated that more than 20,000 yellow-billed kites were poached for consumption and for sale in fetish markets. Researchers tallied nearly 2,000 birds for sale in markets.
- Poaching is also occurring in neighboring Togo and Nigeria.
- Experts are concerned that at this scale, poaching could quickly lead to population-level declines. They urge action to control hunting and sale of this bird.
Rare seed collection offers hope for last wild tree of its kind from Chile
On Chile’s Robinson Crusoe Island, in the South Pacific, a tree juts out precariously from the side of a steep cliff. It’s the last known wild individual of Dendroseris neriifolia. To prevent its total extinction in the wild, conservationists recently collected seeds from the tree and have begun trials to cultivate them. All 11 species […]
Listen to whales to improve connection, care & ocean health (commentary)
- From establishing conservation protections to developing tools to understand whale communication, the work of marine biologist David Gruber and oceanographer Sylvia Earle is grounded in the same belief: understanding leads to connection and care.
- While there have been remarkable conservation successes across the five decades of their efforts, the overall trend is clear: the health of the ocean is declining faster than efforts to protect it.
- “We still have an opportunity to leave future generations an ocean filled with life, wonder, and possibility. But this window is closing. The choices we make in the next decade will firmly shape the future of marine ecosystems,” the co-authors argue.
- This article is a commentary. The views expressed are those of the authors, not necessarily of Mongabay.
Australia’s seagrass meadows under pressure as climate change turns up the heat
- Australia is a global stronghold for seagrasses, the flowering plants that grow in coastal waters and bays.
- Seagrasses are unsung but vital ecosystem engineers: They stabilize sediments, provide habitat and food for marine species, help cleanse the water column of pollutants and sequester vast amounts of carbon dioxide.
- Across Australia’s waters, these undersea meadows are suffering as coasts are developed, seas are polluted and climate change continues to raise water temperatures.
- Conservationists are working to restore seagrasses and build resilience to preserve these vital marine ecosystems.
Endangered West African leopards show signs of recovery, despite odds. ‘It’s a win’
- Researchers working in Benin’s Pendjari National Park reported some promising news for West African leopards: Density rose from 2017 to 2023.
- West Africa’ leopards are regionally endangered, with just 354 remaining across the region.
- Pendjari National Park sits within the W-Arly-Pendjari Complex, a large transboundary conservation landscape encompassing national parks, hunting reserves and buffer zones that in recent years has been infiltrated by non-state armed groups operating in the Sahel. While conservation efforts in the national park are working, the security crisis remains a major threat.
Wildlife’s unpredictable movements make climate-change planning difficult
- Ecologists expected many species to shift northward or upslope in response to warming temperatures, but only about half of observed range shifts so far align with their projections.
- Species responses are likely shaped by multiple factors — changing habitat, rainfall and food availability — not just temperature. Some species may be unable to move, trapped within a fragmented habitat.
- Research shows animals that move toward higher latitudes don’t necessarily fare better.
- These mismatches between predictions and reality create more uncertainty for conservation planning and how best to support species adaptation through corridors.
Gelada monkeys huddle in the cold: Photo of the week
A group of geladas monkeys (Theropithecus gelada), pictured above, huddle to keep warm on a cold day in the Wilhelma Zoo in Stuttgart, Germany. Endemic to Ethiopia’s cold Afroalpine and sub-Afroalpine grasslands, the species is the only primate, apart from humans, that primarily lives on land rather than trees. They spend most of their time […]
Mel Sunquist, field biologist and mentor to generations of conservationists
- Mel Sunquist helped pioneer the use of radio telemetry to study wild tigers, jaguars, and other elusive carnivores, transforming how scientists understood their behavior and ecology.
- His research in Nepal provided some of the first detailed evidence of tiger movements, territories, and social organization, laying foundations for modern tiger conservation.
- As a professor at the University of Florida, he trained generations of wildlife biologists, many of whom went on to lead conservation programs and research around the world.
- Remembered for his humility, patience, and deep respect for animals, Sunquist taught that careful observation, sound science, and thoughtful mentorship were as important to conservation as the discoveries themselves.
Chewing sounds can help decode an animal’s diet using AI, new study finds
- Scientists have developed an AI model that can listen to the chewing sounds of predators and identify what they are eating.
- The tool was trained with audio of whitespotted eagle rays crushing open shells of the mollusks they are preying on.
- It’s crucial to understand predator-prey interactions to figure out the resources the predator depends on and the pressure it puts on prey.
How leopards and wolves share the same Himalayan valley: Study
Three of Asia’s most formidable predators share territory in a remote Nepal valley by eating different prey, according to a new study. Researchers found that diet, not time or space, is what keeps snow leopards (Panthera uncia), common leopards (Panthera pardus), and Himalayan wolves (Canis lupus chanco) from coming into direct conflict. The study, published […]
Rodent-killing baits threaten small wild cats and other wildlife
- Anticoagulant rodenticides — used to control rodent populations — pose a little-recognized threat to a host of wildlife species, including wild cats.
- Many small cat species hunt rodents and live in areas where rat poison is commonly used, including agricultural lands. These anticoagulant poisons accumulate in the liver and can prove lethal: It takes days for animals to die from internal bleeding.
- Widespread exposure in bobcats and caracals is well-documented, however research on other small cat species is limited — but concerning.
- Wildlife biologists say that greater controls limiting the use and availability of rodenticides are needed to protect wildlife.
Vanilla, fake eggs and nausea: How Australian scientists are training foxes to avoid turtle nests
- Freshwater turtles in Australia’s Murray-Darling Basin are disappearing. Introduced red foxes — which prey on their eggs — are considered one of the leading threats.
- Researchers from La Trobe University are testing a non-lethal conservation method called “conditioned taste aversion,” using chemically treated poultry eggs to teach foxes to associate turtle nests with nausea.
- Early trials have shown promising but variable results, reducing nest predation by 30-90% depending on the site. Researchers are working to make the aversion longer-lasting.
- The project is being carried out in collaboration with Traditional Owners, community conservation groups and citizen scientists, with the long-term goal of developing a simple, accessible protocol that could help protect turtles, as well as other ground-nesting native species threatened by introduced predators.
The bats that pollinate for tequila: Photo of the week
A Mexican long-tongued bat, featured above, flies into the blooms of an agave plant, a feeding and pollination technique used to reach nectar. The bats (Choeronycteris mexicana) have unusually long tongues to access nectar while their impact spreads pollen grains everywhere to pollinate nearby agave. Peter Hudson, a professor of biology at Penn State University, […]
The long and winding road to safe highways: Inside the global movement to reconnect habitat
- Across the globe, roads pose a deadly physical threat to wildlife and fragment the landscapes animals need to move through to survive. For some species, a road is a wall: They won’t even attempt to cross.
- Decades of research have proved that wildlife crossings (underpasses and overpasses), combined with roadside fences, prevent deadly collisions, protecting both animals and people.
- Crossings are part of larger efforts to reconnect shattered ecological corridors worldwide. Animals need to move to find food, water, a mate — and to escape more frequent, extreme wildfires and extreme weather events.
- Some of the motivation in building and retrofitting wildlife bridges and underpasses involves public safety and economics. Crashes with large animals cost the U.S. economy more than $10 billion each year.
Urban wildlife is changing from the inside out (commentary)
- Cities are now home to wildlife like foxes, parrots, monkeys, raccoons, boars, and countless bird species, which are not temporary visitors, but permanent urban residents.
- If we want to support their long-term survival, we need to understand how urban environments shape them at every level, from behavior to bacteria, and this includes their gut microbiome, which shapes behavior and other factors.
- “The microbiome is not a niche scientific curiosity, it is a biological system that influences how animals eat, think, move, and cope with stress. And in a rapidly urbanizing world, it may be one of the most important and overlooked tools we have for understanding how wildlife adapts to human-dominated landscapes,” a new op-ed argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
Ancient Maya knowledge helps Guatemalan farmers cut agrochemical use
- Guatemalan farmers are turning to organic pesticides, rooted in traditional practices and sustainable ideas, to replace expensive synthetic alternatives.
- Using a mixture of locally available plants, and ideas about farming passed down by ancestors, they are creating natural pesticides to protect their plots.
- Cheaper than agrochemicals, these biopesticides are safer to use and don’t cause the ecological damage associated with chemical use.
- Although international interest in biopesticides is growing, agrochemicals still dominate the market.
Offshore wind power cables can affect sensory system of sharks and rays: studies
- A series of studies found that electromagnetic fields from offshore-wind farm cables can trigger various effects in bottom-dwelling sharks and rays depending on species and life stage.
- Experiments on small-spotted catsharks and thornback rays showed behavioral and developmental responses.
- The researchers concluded that electromagnetic fields may increase predation risk during early development by altering natural behaviors linked to predator avoidance.
- eDNA surveys detected multiple shark and ray species inside offshore wind farms, suggesting they may serve as potential refuge areas, though major knowledge gaps remain.
Conservationists wary of Nepal’s plan to relocate blackbucks
Nepal is preparing to relocate 18 blackbucks from the country’s west to its south central region, near the popular Chitwan National Park. Officials say the translocation will help establish a population of the antelope in a new habitat and safeguard the species against localized disasters or disease, but conservationists question the choice of habitat and […]
Household mosquito repellents may stop bumblebees from finding their way home
A chemical used in mosquito repellents may disorient bumblebees, stopping them from finding their way back to their nests, a recent study found. Researchers in Finland exposed 123 buff-tailed bumblebees (Bombus terrestris), one of the most abundant bumblebee species in Europe, to a standard consumer mosquito repellent containing prallethrin, a type of pyrethroid insecticide. One […]
How much suffering do invasive species cause? Researchers are measuring that
- Researchers have developed a new framework for measuring the suffering caused by invasive species, which they hope will complement the existing global standard for assessing these species’ impact on native biodiversity.
- Initial case studies from around the world assessed by the Animal Welfare Impact Classification for Invasion Science (AWICIS) suggest that the suffering caused by invasive ants and flies has been systematically overlooked. Focusing on welfare impacts also challenges conservationists to consider how management might harm invasives themselves.
- Results from AWICIS were, however, skewed by a relative lack of research describing invasive welfare impacts in lower-income countries. Its authors hope AWICIS’ adoption will encourage conservationists to record suffering more regularly and systematically.
Most wildlife AI focuses on the ground. This model looks up in the trees
- Scientists have developed a new artificial intelligence model that can detect and identify tree-dwelling species.
- TropiCam-AI can recognize 84 taxa, including 63 species, with the tool showing an accuracy of 95% with the majority of the taxa.
- AI is widely used to automate the detection of animals from camera-trap data sets that can run into millions of images.
- However, the existing AI models developed for this purpose focus primarily on ground-dwelling animals, with tree-dwelling species largely overlooked.
Amid efforts to save Australia’s southern cassowaries, their numbers remain unknown
- The southern cassowary, a rare and elusive rainforest bird that lives along Queensland’s northern coast, once faced extinction. Now, its numbers are stable, but scientists still lack an up-to-date estimate of how many remain.
- Shrinking habitat was a key factor in the bird’s decline, but designation of the northeast coast “Wet Tropics” as a World Heritage Site protected both the ecosystem and the cassowaries that live there.
- As an important seed disperser, this bird helps sustain this rainforest’s plants and trees, but its slow breeding and need for large, connected habitats make it vulnerable.
- Growing threats from road collisions and intensifying cyclones, heat waves and other climate impacts are putting renewed pressure on this bird and increasing urgency for better monitoring and conservation.
Nepal’s plan to release blackbucks into tiger country raises red flags
- Nepali authorities will relocate 18 blackbucks to an enclosure near Chitwan National Park to establish a new habitat for the critically endangered animals, which in Nepal are currently found only in Bardiya and Shuklaphanta.
- However, Chitwan’s monsoonal climate, competition from other deer species, and the presence of tigers and leopards are likely to increase physiological and behavioral stress for the blackbucks, conservationists warn.
- They’ve also flagged the relocation enclosure’s proximity to a municipal waste dump and a carnival ground, and warned of potential disturbances from tourists.
- Earlier translocations to Shuklaphanta were considered successful, helping to boost Nepal’s blackbuck population, largely in human-managed landscapes; but ecologists say true success will be achieved only when the animals are released into the wild and can sustain a self-sufficient, breeding population.
Endangered Persian leopards persist across borders, despite hunters and landmines
- There are fewer than 1,100 Persian leopards left in the wild, with 80% — perhaps 732 individuals — concentrated in Iran. A handful remain in Russia, the Caucasus and countries across Central Asia.
- This leopard subspecies is endangered and declining, driven to the brink of extinction in habitats across its range across southwestern and Central Asia.
- More than half of all recorded leopard deaths are from retaliatory killings by local communities, who poison, trap or shoot leopards in response to livestock predation. They can also be maimed or killed by snares and traps intended for other, smaller prey.
- The Persian leopard now occupies around one-quarter of its historical range. Their habitat is fragmented and crisscrossed by dangerous roadways and broken by international borders that are fenced or laced with landmines.
From caws to code: AI helps decrypt animal communication
- Scientists are increasingly using artificial intelligence models to decode the communications of other species.
- The Earth Species Project has built a generalizable model that could be used across species; the team also works with scientists around the world to develop custom models for specific species.
- In northern Spain, ESP’s AI tools are helping scientists understand how a population of cooperative-breeding crows communicate with one another.
- The technology is also being deployed to understand how orcas communicate with each other, and how underwater noise affects their communication.
New study explores how reforestation could help Java’s leopards survive
- A new study finds that strategically restoring degraded forests could help reconnect fragmented habitat for the endangered Javan leopard, giving the species more room to move across densely populated Java.
- Researchers created the first islandwide model of habitat connectivity for the species, showing how targeted reforestation could help offset some of the barriers created by roads, railways and urban development.
- Conservationists say isolated leopard populations face increasing risks from habitat loss, human conflict, disease and inbreeding, with only an estimated 320 Javan leopards remaining in the wild.
- Experts caution that the model still needs to be tested with real-world tracking data, but say reconnecting forests will be essential for the long-term survival of Java’s last apex predator.
No beak = weak? Not for this New Zealand parrot that’s the alpha male of his flock
For many birds, survival depends heavily on their beaks. Beaks are used for eating, hygiene and even fighting, so a broken or deformed beak can often be a death sentence. But for one kea parrot, an endangered species endemic to Aotearoa New Zealand, scientists observed the exact opposite, despite the bird missing its entire upper […]
Asia’s mainland leopard cat is abundant but still cloaked in mystery
- Widespread, adaptable, and classified globally as a species of “least concern” on the IUCN Red List, the mainland leopard cat can be found across much of Asia. However, research on the species remains relatively limited.
- Despite its global status, local populations face serious threats — including habitat loss, hunting, vehicle collisions, and genetic isolation — and in some cases are considered locally critically endangered. Global assessments can mask these regional declines due to how conservation status is assessed.
- Researchers highlight knowledge gaps caused by underfunding, language and geopolitical barriers, along with unshared data. They stress that more focused studies, genetic research, and conservation initiatives that involve local communities are essential to protecting this ecologically important species.

The tiny-brained mothers who remember where every child is buried
Rethinking conservation through elephants’ sense of time and memory
Historically, conservation has mostly focused on numbers like population and habitat size. However, in the mid-2000s, scientists started to investigate animal emotions, even trauma, when considering conservation success. In a recent Mongabay podcast, Khatijah Rahmat, a geographer at the Max Planck Institute for the History of Science, shared her research examining how elephants perceive and […]
Unusual ant interaction hints at mutualistic ‘cleaning’ system
Some coral reef ecosystems famously have “cleaning stations,” where fish line up to be cleaned by other species of fish and shrimp. Entomologist Mark Moffet recently published observations of what appears to be a similar relationship in ants. In the Chiricahua Mountains of the U.S. state of Arizona, Moffet, from the National Museum of Natural […]
The value of South Africa’s wildlife shouldn’t be in the hands of wealthy foreign hunters (commentary)
- The latest statistics on South Africa’s professional (“trophy”) hunting industry reveal a large increase in animals hunted, with numbers set to rise in coming years, under the logic that the revenue generated is necessary for managing wildlife.
- But should the conservation of the nation’s wildlife, which have their own roles in natural ecosystems, depend on their ability to generate an enormous income for a select group of wealthy farmers and professional hunters, a new op-ed asks.
- “When conservation is built on the premise that wildlife must pay its way to exist, we should ask not only who benefits, but what is being lost, and at whose expense,” the author writes.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
Cocaine exposure drives salmon to alter movements
Young Atlantic salmon exposed to cocaine and its breakdown product, benzoylecgonine, swim farther and more widely in the wild, a new study shows. This behavioral change can put them in risky situations, researchers say. “[T]he effects of illicit drug pollution on aquatic wildlife is not just a laboratory finding — it can measurably alter wildlife […]
Conservationist wins top award to protect lions and people in Zimbabwe
- A Zimbabwean conservationist working to reduce conflict between lions and livestock farmers is a winner of one of this year’s Whitley Awards, better known as the “Green Oscars.”
- The prize money will fund the expansion of the work led by Moreangels Mbizah and her NGO, Wildlife Conservation Action, in a region that is a hotspot for human-carnivore conflict.
-
Community guardians employed by WCA warn farmers when lions enter their farming areas; promote the use of secure animal enclosures for cattle, goats and sheep, and oversee the installation of solar-powered flashing lights to deter nocturnal raids by lions.
-
These interventions have reduced conflict by up to 98% in at least two rural wards, but habitat loss through the expansion of farms into wildlife migration corridors worries Mbizah and her team.
Rare, high-altitude jaguar sighting in Honduras raises hope for conservation
- For the first time in a decade, camera traps set up high in the Sierra del Merendón mountain range in Honduras captured images of a male jaguar.
- The cat was documented at an altitude of 2,200 meters (about 7,200 feet), much higher than their normal range. Jaguars typically live below 1,000 m (3,300 ft).
- These mountains can act as a high-elevation corridor for animals to move between landscapes in Honduras, Guatemala and beyond.
- Jaguars, like all big cats, continue to lose habitat and are targeted by poachers. But this cat moving back into its former territory shows that conservation efforts, such as anti-poaching patrols, land protection and the introduction of prey species, may be working.
Chimp ‘civil war’ follows rare community split in a Ugandan national park
- A 30-year study documents a rare split within a chimpanzee community in Uganda’s Kibale National Park — one that sparked a deadly war.
- Two rival chimp groups have staged coordinated raids that killed both adult males and infants.
- Researchers recorded at least 24 attacks between 2018 and 2024, suggesting unusually intense violence.
- The findings show how shifting social ties can fracture animal societies and trigger collective violence.
A chimpanzee’s rhythmic drumming with floorboards hints at origins of instruments
- A captive chimpanzee in Japan spontaneously ripped floorboards from a walkway and used them as instruments to perform structured, rhythmic drumming displays while vocalizing
- Researchers recorded 89 performances and found the drumming wasn’t random and followed a structured, rhythmic pattern similar to chimpanzee vocal calls.
- The chimp displayed play faces and what appeared to be laughter while drumming, suggesting the behavior was emotionally rewarding, not just a social display.
- The findings support the hypothesis that instrumental music may have evolved from vocal emotional expression, though the study is limited to a single individual in a captive setting.
Coexisting with America’s growing urban coyote population is easier than you think
Coyotes are now present in almost every major urban-metropolitan area in the United States, yet conflicts between the canines and humans are exceptionally low. Between 1960 and 2006, only 146 documented coyote attacks on humans occurred in the U.S. and Canada. Yet there are 4.5 million dog attacks on humans annually in the U.S. alone. […]
George Schaller: The field biologist who helped redefine conservation
- Miriam Horn’s Homesick for a World Unknown traces the life of George B. Schaller, a field biologist whose work reshaped how animals are studied and understood.
- The book portrays a scientist defined by patience, close observation, and a disciplined effort to understand animals on their own terms, even as such an approach ran against prevailing scientific norms.
- Horn presents Schaller’s career across continents as both scientific and practical, showing how his research informed the creation of protected areas while gradually incorporating local knowledge and participation.
- Rather than probing for psychological insight, the biography mirrors its subject’s outward focus, offering a restrained account that raises broader questions about attention, conservation, and what it means to share a world with other species.
Researchers find ‘remarkable’ hot-pink insect in Panama rainforest
In March 2025, biologist Benito Wainwright and his colleagues were searching for katydids — leaf-mimicking insects related to crickets and grasshoppers — in the rainforest of Barro Colorado Island in Panama, when they came across an unexpected sight: a hot-pink katydid individual of the species Arota festae. The researchers captured the katydid and raised her […]
Loss of prey could drive Atlantic Forest jaguars to extinction
- There’s little prey left for jaguars in Brazil’s Atlantic Forest, which is driving the big cat’s decline there, according to new research.
- Hunting is wiping out species like deer and peccaries that sustain jaguars, which could spell localized extinctions for the fewer than 300 jaguars thought to remain there.
- To save these last jaguars, enforcement is needed to reduce hunting, the study authors and conservationists say.
- It may be necessary to translocate prey species to rewild this forest, experts say, and fragmented habitat must be reconnected to allow safe movement for jaguars and other wildlife.
A French city cut its marine pollution — and its seagrass bounced back
- Neptune grass is generally regarded as the most ecologically important seagrass and shallow-water habitat in the Mediterranean Sea, where it is endemic. But the species has been in decline for many decades.
- A new study found that following the introduction of stronger environmental regulations and practices in the mid-to-late 1980s, Neptune grass (Posidonia oceanica) repopulated sampled sections of the waters off Marseille, France, over the ensuing four decades at rates that experts called “exceptional” and “remarkable.”
- The lead author said the study shows the value of passive restoration: letting seagrass meadows regrow on their own after removing the human-caused drivers of decline, rather than focusing on replanting or transplanting the species.
Pyrenees brown bear population climbs to an estimated 130 in latest census
The annual census of brown bears in the Pyrenees mountain range of Spain, France and Andorra estimated that 130 bears are now living in the region with an average annual population growth rate of more than 11% over the last 18 years. The subpopulation of Pyrenees brown bear (Ursus arctos arctos) has been steadily increasing […]
Australia’s flying foxes offer valuable services & deserve better reputation: Study
A new study in Scientific Reports provides the first economic valuation of the ecosystem services provided by flying foxes in Australia, focusing on their significant contribution to the timber industry.
Poop pills and gut microbes: Wildlife microbiome studies aid conservation
- Recent research into the human microbiome is revealing how closely connected it is to our health. Similarly, scientists are exploring how the microbiome in wildlife species can aid conservation efforts.
- Studies show that human action (including climate change and close proximity to people) is altering the microbiomes of multiple wildlife species. The implications of how these changes may be impacting wildlife survival and health remain unclear.
- Researchers are also exploring how supporting a diverse wildlife microbiome can improve animal health in captivity, aid recovery during rehabilitation, and even boost reintroduction success. Microbiome studies are underway on numerous species, ranging from Australian koalas to African meerkats and cheetahs.
- Though still an emerging field, fecal microbiota transplants (FMTs) are just one possible tool that researchers and conservationists are exploring in trials to see how the restoration of a healthy diverse microbiome can support wildlife conservation.
Asian wild dog spotted in Vietnam for the first time in 20 years
Recent research has confirmed the first sighting of a dhole in more than two decades, a reddish-brown wild dog native to Asia. Before the sighting, the predator was believed to be extinct in Vietnam. The dhole (Cuon alpinus), historically one of the most widespread large carnivores in Asia, was seen on camera-trap footage. The single […]
A bonobo named Kanzi could play pretend, challenging ideas about animal imaginations
- Kanzi, a language-trained bonobo, identified and tracked pretend objects across tea party-like experiments, marking the first controlled demonstration of imagination in a nonhuman animal
- In three experiments, Kanzi repeatedly pointed to the correct location of imaginary juice and grapes, and chose real juice over pretend juice, showing that he understood the difference between real and imaginary objects.
- This study suggests that the cognitive capacity for imagination may date back 6 to 9 million years to the common ancestor of humans and great apes, though some researchers question whether simpler explanations could account for Kanzi’s responses.
- Kanzi died in March 2025 at age 44, but researchers hope to explore whether other apes, including those without extensive human language training, share this capacity.
Amazon waterway noise threatens unique social life of giant river turtles
- A planned shipping waterway on the Tapajós River, a major tributary of the Amazon, may disrupt the sophisticated social communication systems used by the Amazon river turtle (Podocnemis expansa), a species likely to be endangered.
- Underwater noise from barges risks drowning out the vocalizations used by adult females to guide their young during collective migration in the species’ second-most important nesting area, scientists say.
- The waterway is a central piece of Brazil’s new push to ease the transport of soybean and corn for export.
Study finds livestock pushing lions away from shared rangeland in Kenya
- A new study in Kenya’s Mara conservancies finds lions increasingly avoiding areas used by Maasai livestock, even after the animals have moved on.
- Researchers suggest lions are responding not just to immediate encounters with herders but to past grazing pressure and perceived long-term risk.
- The findings raise questions about how livestock grazing may reshape predator behavior and wildlife use of shared landscapes.
- Experts say any grazing limits must balance conservation goals with Maasai livelihoods that depend heavily on livestock.
Indigenous knowledge helps guide conservation of Australia’s endangered northern quoll
- A new study from northern Australia has highlighted the importance of Indigenous cultural and ecological knowledge (ICEK) in conservation efforts of the northern quoll (Dasyurus hallucatus), an endangered carnivorous marsupial.
- This study, published in Wildlife Research, was led by the Martu people, whose lands lie in the state of Western Australia.
- The study finds that cultural knowledge has helped provide a historical baseline for the northern quoll in areas that were previously undocumented by Western science.
- By integrating cultural knowledge with contemporary conservation strategies, the study shows that culturally and ecologically informed approaches can be developed to conserve northern quoll populations on Martu lands, ensuring the resilience of both the species and the landscapes they inhabit.
Satellite images identify vulture breeding colonies by their droppings
- A new study reveals that colonies of critically endangered Rüppell’s vultures are visible via satellite images.
- A group of researchers scanned more than 6 million square kilometers (2.3 million square miles) in seven countries in East and Central Africa to look for the tell-tale whitewash formed by droppings deposited by the birds beneath their nests.
- In all, the team pinpointed 232 potential nesting sites, mostly in Sudan, South Sudan and Chad.
- Following declines of more than 90% for the species over the past 40 years, knowing where Rüppell’s vultures nest can help conservationists ensure their protection.
Out of captivity, into conflict: slow lorises struggle to survive after release
- A study in Bangladesh found that seven of nine rescued Bengal slow lorises died within six months of release, showing that rewilding trafficked animals can become a “death trap” if habitat and social conditions aren’t right.
- Most of the dead lorises bore venomous bite wounds from their wild counterparts, indicating that releasing highly territorial animals into already occupied forests can trigger lethal fights.
- The two that survived established larger home ranges, while those kept longer in captivity fared worse, underscoring the need for careful site selection, population surveys, and evidence-based release protocols.
- Experts say that rescue and release only address the symptoms of illegal wildlife trafficking, and that curbing poaching and habitat loss is essential to prevent further harm to both individuals and wild populations.
Botswana shows how smarter cattle herding can save lions, reopen ancient wildlife pathways
- Restoring traditional herding practices in northern Botswana has led to a huge decrease in cattle predation and retaliatory lion poisonings in the Okavango Delta region.
- More lion cubs are now surviving, with the lion population in northern Botswana up 50% over the past four years.
- Experts say bringing back traditional herding practices is the key to restoring migration routes for wildebeest, zebra and many other species.
- If herding expands, government officials may consider removing some veterinary cordon fences that have blocked wildlife corridors for decades.
Africa’s vulture safe zones face tough test across vast landscapes
- Vulture safe zones have multiplied across Southern Africa to address the numerous threats facing these scavengers.
- The vulture safe zone concept originated in Asia as a response to the drastic decline in the region’s vulture populations due to diclofenac poisoning.
- Opinions are mixed on their effectiveness to address the multitude of threats facing species in Africa.
- In the coming months, conservation organizations are aiming to streamline the concept in Africa, with the aim of standardizing how these safe zones operate and monitor populations, and ultimately how they protect threatened species.
Researchers eye jaguar conservation wins under Brazil Indigenous stewardship project
- The jaguar is listed as near threatened on the IUCN Red List due to threats such as habitat loss and overhunting, but finds a safe haven in Brazil within protected areas and Indigenous lands.
- A pioneering new Brazilian initiative seeks to strengthen the protection of 15 Indigenous territories and their biodiversity through land sovereignty, environmental restoration and monitoring.
- The initiative may benefit jaguar conservation in one of the big cat’s last remaining strongholds.
- The initiative is still in its early stages, and so far there are little to no links between the project and jaguar conservation programs. But researchers say they hope conservation efforts, even if not explicitly aimed at jaguars, can have a ripple effect on protecting the species.
Mapping underground fungal networks: Interview with SPUN’s Toby Kiers
- Mycorrhizal fungi are found in every soil system on Earth, and have symbiotic relationships with the plants whose roots they live on.
- They receive carbon dioxide from plants in exchange for nutrients, making them major carbon repositories and an important tool for carbon sequestration.
- The Society for the Protection of Underground Networks (SPUN) is deploying a wide range of technologies, from remote sensing to imaging robots, to map these crucial underground networks.
- “We think of these networks as one of Earth’s circulatory systems, but people are not paying attention,” SPUN co-founder Toby Kiers tells Mongabay in an interview.
Scientists call for ethics rules as AI fuels animal communication research
Researchers have proposed a new ethical framework to regulate emerging technologies, such as artificial intelligence and machine learning, used to decode animal communication, Ana Cristina Alvarado reports for Mongabay Latam. The proposed guidelines, known as the PEPP Framework, which stands for Prepare, Engage, Prevent and Protect, lay out the principles for studying animal communication responsibly. […]
Brazil’s Rio de Janeiro bans shark meat in most state schools
The Brazilian state of Rio de Janeiro recently announced it has banned the purchase of shark meat for roughly 95% of its state-run schools, citing environmental and health concerns. A July 2025 Mongabay investigation found shark meat was commonly purchased for use across Brazil in public institutions, including eldercare facilities and schools. The exposé found […]
Rodent burrows offer unusual sanctuary to Africa’s smallest wildcat
- New research shows female black-footed cats rely heavily on abandoned springhare burrows to shelter themselves and raise their kittens, using a constantly shifting network of underground dens to survive Southern Africa’s harsh, semiarid landscape.
- Mothers rotate frequently among multiple dens — sometimes almost daily once kittens begin to move — a strategy likely aimed at avoiding predators and minimizing scent trails.
- Despite weighing as little as 1 kilogram (2.2 pounds), black-footed cats are among the most active and efficient hunters of any feline, ranging over large territories at night and retreating underground by day.
- With low reproductive rates, disease pressure and a population of around 10,000, the species’ survival depends on protecting both springhares and the working landscapes of livestock farms, where burrow loss, overgrazing and predator control can indirectly threaten the cats.
Risk-taking comes earlier in chimpanzees than in humans, study finds
- A study found that chimpanzees tend to take more physical risks as infants and young animals rather than as adolescents, like humans.
- The researchers hypothesize that the level of care humans provide may cut down on the risks young children might otherwise take.
- The team tracked how often 119 chimps dropped or leaped through the forests without holding onto any branches at Uganda’s Ngogo Chimpanzee Project, and analyzed the results according to the animals’ ages.
- Infant and young chimpanzees were more likely to launch themselves through the trees than adolescents or adults, despite the risk of injury.
African wild dogs break the carnivore rule in Botswana
For the first time, “hyper-carnivorous” African wild dogs have been recorded eating fruit, a behavior so far documented only in a small part of Botswana’s wildlife-rich Okavango Delta. The wild dogs were seen picking up jackalberries, the fruit of the African ebony tree (Diospyros mespiliformis), with their teeth and swallowing them almost whole. Jackalberries […]
Five detained over alleged hunting in Javan leopard habitat
- Indonesian authorities have detained five people following allegations of illegal hunting inside West Java’s Gunung Sanggabuana conservation forest.
- The case drew national attention after camera trap footage revealed an injured Javan leopard and suspected armed hunters operating in the protected area.
- Conservationists say the incident exposes deeper weaknesses in wildlife protection and raises urgent questions about how Indonesia safeguards its last remaining big cats.
Study ties same-sex behavior in primates to ecological and social pressures
- A recent study into same-sex behavior in primates finds that social organization and ecological factors, including climatic conditions, influence this behavior.
- In gorilla groups, same-sex relations can help strengthen social bonds, study lead author Chloë Coxshall told Mongabay, reducing competition and facilitating access to mates and resources.
- Gorilla groups typically consist of a dominant adult male, several adult females, and their offspring. If the dominant male has the exclusive right to mate with all females of the same group, sometimes this polygamy pushes the females to leave this family to look for other females with whom they develop intimate relationships, Malagasy primatologist Jonah Henri Ratsimbazafy said.
- Same-sex behavior doesn’t appear to have the same place in the lives of different primate species or even at various times for the same population, the study suggests. So species-specific research is needed, according to the study authors.
Honeyguide birds learn local human dialects
In northern Mozambique, local honey-hunters use vocal signals to communicate with wild honeyguide birds to locate and harvest honey. New research finds that human calls used across the region vary, but the birds learn these subtle differences and continue to cooperate with their human partners, guiding them to wild bees’ nests. The study focused on […]
The bird that builds tree skyscrapers: The oropendola
High in the Amazon canopy, oropendolas build some of the rainforest’s most incredible architecture: huge hanging pouch nests woven from fibers, vines and leaves. Hundreds of these nests form entire “tree cities” suspended 30 meters above the ground. But the design isn’t just impressive — it’s strategic. Toucans constantly try to raid the nests, so […]
Amazon entrepreneur spreads seeds of growth with recycled paper
- In the Brazilian city of Altamira, a small business transforms recycled paper into seed-embedded sheets that grow into flowers, herbs and even local plants, merging creativity and sustainability.
- Founder Alessandra Moreira turned personal adversity into purpose, building a backyard business that inspires sustainable entrepreneurship.
- Experts say initiatives like Ecoplante embody the future of the Amazon’s bioeconomy, where innovation, inclusion and forest conservation can grow hand in hand.
Poaching down but threats remain for forest elephants, recent population assessment finds
- The first authoritative population assessment for African forest elephants estimates there are more than 145,000 individuals.
- Researchers say new survey techniques relying on sampling DNA from elephant dung provide the most accurate estimate of a species that’s difficult to count in its rainforest habitat.
- Central Africa remains the species’ stronghold, home to nearly 96% of forest elephants, with densely forested Gabon hosting 95,000 individuals.
- Conservationists say the findings can help inform the design of targeted conservation actions and national plans for forest elephants.
5 unexpected animal behaviors we learned about in 2025
Every year, researchers and people out in nature capture some aspect of animal behavior that’s unusual or unexpected in some way, changing how we understand the natural world. Here are five such examples that Mongabay reported on in 2025: Massive fish aggregation seen climbing waterfalls in Brazil For the first time, scientists observed a “massive […]
How are California’s birds faring amid ever more frequent wildfires?
- Long-term research in California shows that many bird populations increase after wildfires and can remain more abundant in burned areas for decades, especially following moderate fires.
- Although some bird species are adapted to fire and benefit from low to moderately severe blazes, megafires in California are becoming more frequent.
- Megafires, scientists say, are unlikely to benefit most bird species and harm those that depend on old-growth forests.
- Wildfire smoke poses a serious threat to birds’ health, with evidence linking heavy exposure to particulate matter in smoke to reduced activity, weight loss and, possibly, increased mortality.

In Nepal, the world’s smallest otter continues to elude researchers
- The Asian small-clawed otter was rediscovered in Nepal in 2024 after 185 years. Since then, however, it’s gone dark again, with no more confirmed sightings.
- Identifying the animal remains challenging due to its small size, dietary overlap with other carnivores, and resemblance to common species such as the crab-eating mongoose.
- Funding and logistical constraints impede targeted surveys, as conservation priorities in Nepal focus mainly on larger, charismatic species such as tigers and rhinos.
- Despite this, conservationists are already planning measures to reduce potential threats to the animal by including it into the national otter conservation action plan.
Tanzania’s tree-climbing hyraxes have adapted to life without trees
Despite their name, tree hyraxes — small, furry, nocturnal African mammals — don’t always live in trees. In Tanzania’s Pare mountains, near the border with Kenya, they’ve adapted to life on steep rocky outcrops as forests disappeared over the centuries, a recent study has found. Eastern tree hyraxes (Dendrohyrax validus) are known to inhabit the […]
Tsunami veteran rescue elephants mobilized for Indonesia cyclone disaster relief
- The number of people killed by flash floods after Cyclone Senyar made landfall over Sumatra on Nov. 26 increased to 1,059 on Dec. 18. In Pidie Jaya district, on the north coast of the semi-autonomous region of Aceh, officials assigned a team of four rescue elephants, veterans of the recovery operation after the 2004 Boxing Day tsunami that killed more than 200,000 people in Aceh.
- The Aceh conservation agency said the elephants were uniquely able to help remove fields of logs carried down valleys by the worst flash floods to hit the region in years, with the scale of debris fields impassable to heavy machinery.
- “They are trained and experienced elephants,” the head of Aceh’s conservation agency told Mongabay, while emphasizing that officials went to great lengths to ensure the Sumatran animals’ welfare.
- At least one Sumatran elephant was presumed killed in flash floods caused by Cyclone Senyar, after residents in a village neighboring the rescue elephants’ workplace discovered the animal’s body Nov. 29.
In Peru, community-led camera trapping boosts conservation and ecotourism
- Community members in Alto Mayo, Peru, are protecting 4,000 hectares (nearly 10,000 acres) of unique wetland forest by combining sustainable ecotourism, scientific research and participatory management of the territory.
- In the Tingana Conservation Concession, visitors explore the flooded forests by canoe and learn about sustainable agriculture and local species, while contributing revenue to the community’s economy.
- Since 2023, community members have installed eight camera traps to monitor biodiversity and strengthen surveillance against encroachers.
- The cameras have captured species like jaguarundis, margays, neotropical otters and razor-billed curassows, providing valuable scientific information that has been integrated into local environmental education programs.
‘Internet of Animals,’ a unified wildlife tracker, set to resume after hiatus
- A global project that tracks wildlife via satellites has resumed operations after a hiatus of three years.
- Project ICARUS, which aims to create the “internet of animals,” capitalizes on advances in wireless tracking technology to monitor individual animals.
- The trackers record data that will help scientists track the movements, migrations and behaviors of animals in different parts of the world.
- The system also enables scientists and conservationists to understand how animals are interacting with one another and with their respective ecosystems.
Elephant seals can recognize the voices of their rivals
Elephant seals spend most of their lives at sea, returning to shore just twice every year to molt and breed. The breeding season typically includes males weighing thousands of kilograms violently clashing with each other to compete for females. New research finds the hefty mammals remember the voices of rivals they’ve met before and retreat […]
Choosing coexistence over conflict: How some California ranchers are adapting to wolves
- California’s expanding gray wolf numbers — a conservation success for an endangered species — have worried ranchers in recent years as wolf-related livestock kills mount.
- Some ranchers are adapting to the changing landscape, using short-term nonlethal deterrents, some of which are funded by a state compensation program.
- A few ranchers are exploring long-term approaches, such as changing their ranching practices and training their cattle to keep them safe from wolves.
- While change is hard, ranchers acknowledge that learning to live with the new predator is the only way forward, and it pays to find ways to do so.
Predators in peril: Protected areas cover just a fraction of global carnivore ranges
- Globally, human impacts threaten the ranges of carnivores that depend on large swaths of natural land to survive.
- A new study found that a majority of the total, combined range of land-dwelling carnivores falls outside of land designated for habitat conservation.
- Researchers determined that Indigenous lands are particularly important for supporting carnivore ranges.
Octopuses use their arms to sense and respond to microbiomes on the seafloor
- Octopus suckers can sense and react to microbiomes in their environment.
- Distinct microbial populations on objects relevant to the octopus’s survival, like eggs and prey, inform the animal’s behavior.
- Scientists found that in response to different microbial signals, chemotactile receptors trigger reflexive responses in octopus suckers and arms.
Amazon’s stingless bee propolis shows potent healing power, studies show
- Researchers in Brazil identified anti-inflammatory properties of a cream made with the propolis of Amazon stingless bees, with results similar to commercial healing ointments.
- Stingless bees (meliponines) are the primary pollinators for the açaí berry, making their conservation crucial for both the Amazon ecosystem and a billion-dollar global industry.
- For one Amazon family, swapping cattle ranching for beekeeping and cosmetics is a real-world example of a bioeconomy that experts say offers a powerful alternative to deforestation.
First state-authorized killings mark escalation in California’s management of wolves
- California’s wildlife department killed four gray wolves in the Sierra Valley in late October, in a dramatic escalation of tactics to address growing predation of cattle by the canids and despite protection under state and federal endangered species laws.
- The department says the wolves killed at least 88 cattle in Sierra and Plumas counties and continued to target livestock despite months of nonlethal deterrents deployed to drive them away.
- The state employed lethal action despite its compensation program, which pays ranchers for cattle killed by wolves, and additional federal subsidies paid to the livestock industry at large.
- The state wildlife agency confirmed a new pack –– the Grizzly pack–– earlier this week with two adults and a pup. Though the state’s wolf population remains small and vulnerable, ranchers are increasingly concerned about livestock deaths.
Behind Sri Lanka’s ‘fish rain’ lies a web of migrations now blocked by rising dams
- Sri Lanka recently reported a “fish rain,” where fish were found far from water bodies after heavy rains; but rather than falling from the sky, experts say these were amphibious fish that “walked” overland after the rains, making a rare but real phenomenon appear mysterious.
- Events like this highlight the subtle yet vital migrations that many freshwater species undertake — from overland movements by climbing perch and snakeheads, to upstream monsoon breeding runs by small fishes, to the epic sea-to-river-to-sea journeys of eels navigating rocks, dams and reservoirs.
- Such migrations are ecological lifelines, linking wetlands, rivers and coastlines, enriching ecosystems (as with salmon), and ensuring the survival and reproduction of a wide range of freshwater species.
- But in Sri Lanka, a growing network of dams, mini-hydro barriers and irrigation weirs is fragmenting rivers and blocking these ancient routes; despite fish ladders being proposed by dam developers, they’re rarely built, leaving many species unable to complete migrations essential for their survival.
45 more shark species up for CITES protections; tight vote expected
- Twenty-nine houndsharks and 16 gulper sharks are up for listing on CITES Appendix II at the wildlife trade regulator’s summit in Uzbekistan this week.
- Conservationists expect the vote to be close, with critics saying “lookalike” species shouldn’t face trade restrictions. Proponents argue it’s necessary given the lack of knowledge among customs officials.
- Houndsharks are widely consumed for their meat in Europe and Australia, while gulpers are hunted for their liver oil.
Deep-diving manta rays use the ocean’s midnight zone to build mental maps, study suggests
- Oceanic manta rays dive to record depths of 1,250 meters (4,100 feet), according to a first-of-its-kind study to examine in detail the extreme deep-diving behavior of these rays.
- Researchers tracked 24 manta rays between 2012 and 2022, attaching special tags to them in waters off Peru, Indonesia and Aotearoa New Zealand.
- Researchers propose that dives help rays sample stable environmental signals, such as temperature, oxygen levels and possibly magnetic fields, in preparation for navigating the open ocean.
- Extreme dives occurred most frequently when rays left continental shelves, before embarking on long journeys exceeding 200 kilometers (120 miles).
Wolf hauls up crab trap to eat bait, hinting at possible tool use
Researchers in Canada have documented a wild gray wolf hauling a crab trap out of the water to eat the bait inside, according to a recent study. Researchers suggest it may be the first recorded example of possible tool use by a wolf (Canis lupus). The finding emerged from a program maintained by Indigenous Haíɫzaqv […]
Game of tiny thrones: Parasitic ants grab power by turning workers against their queen
Queens of some ant species have evolved an unusually hostile mode for colony takeover: they infiltrate colonies of other ant species and manipulate the worker ants into killing their own queen — their mother — then accepting the intruding queen as their new leader, according to a recent study. In the world of ants, where […]
Newly described ‘lucifer’ bee found visiting critically endangered plant in Australia
In 2019, researcher Kit Prendergast was surveying the insects visiting an incredibly rare plant in the Bremer Ranges of Western Australia when a bee grabbed her attention. Prendergast and her colleague dug deeper and found that the native bee, now named Megachile lucifer, is a new-to-science species, according to a recent study. The species name […]
Asian golden cat range expands, but declines continue amid rising threats
- The Asian golden cat (Catopuma temminckii) is a medium-sized cat species that was once abundant across Asia, ranging from India to China. Today its population is undergoing a significant decline.
- That’s resulted in it now being declared a threatened species as its habitat is lost or fragmented, and indiscriminate snaring removes it from forests, particularly in Southeast Asia.
- Targeted research, conservation and funding are rare for this species, resulting in significant knowledge gaps about its basic ecology and threats. That uncertainty is causing some conservationists to say it could warrant endangered status.
- It’s hoped that increasing threat levels imperiling the Asian golden cat will spur donor funding, giving researchers the tools to shine a light on the needs of this lesser-known felid. Nepal has so far led the way in conservation efforts.
Europe’s under-pressure bats face ‘astonishing’ threat: Ambush by rats
Researchers have captured video of an unexpected predator at two bat hibernation sites in northern Germany: invasive brown rats that lie in wait to intercept the bats mid-flight. Invasive rodents are known predators of native animals on islands, including bats. However, this is likely the first time invasive brown rats (Rattus norvegicus) have been recorded […]
Night dives reveal hidden alliances between young fish and larval anemones
- A new study, drawing on nighttime underwater photography, documented previously unknown “symbiotic associations” between juvenile fish and larval anemones, with some fish staying close to the anemones, and others carrying them around.
- The study suggests the fish may gain protection from predators by associating with the toxic anemones, while the anemones could benefit from being transported by the fish to new parts of the ocean.
- An outside expert also proposed that anemones might receive additional benefits, such as nutrients from the fish’s excretions or from food scraps left behind.
- All of the experts emphasized that more research is needed to fully understand the dynamics of these relationships.
Report finds dangerous mercury levels, highlights mislabeling in shark meat sold in EU
- Nearly a third of shark meat samples taken from products sold in Europe contained dangerously high methylmercury levels, with all tope shark and almost a quarter of blue shark samples exceeding EU safety limits, a new study finds.
- Much shark meat is mislabeled under names like rock salmon, huss or veau de mer, leaving consumers unaware they’re eating shark and could be ingesting a potent neurotoxin.
- Methylmercury can’t be cooked out, builds up in human tissue and can cause lasting neurological harm. Meanwhile, shark populations are declining, threatening marine ecosystem stability.
- The study’s authors urge stricter labeling laws, tighter food monitoring and consumer education, arguing that eating apex predators is both ecologically and medically unsustainable.
Colony of world’s highest-flying bird under threat in Uganda
- Researchers in Uganda say the country’s only nesting site of critically endangered Rüppell’s vultures is under threat from hunting, charcoal burning and farming.
- Two nesting colonies are built on cliff faces in Luku Central Forest Reserve, in Uganda’s northwestern Arua district.
- The district hosts tens of thousands of people displaced by violent conflict in neighboring Democratic Republic of Congo and South Sudan.
- Many of these refugees, as well as native Ugandans, depend on the reserve to eke out a living, but at great cost to the integrity of its forests and wildlife.
California learns from its beaver reintroductions
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. Tásmam Koyóm, a high Sierra meadow in California, U.S. returned to the Mountain Maidu people in 2019, is once again wet where once it had been dry. Rivulets now snake through hip-high grasses and willow thickets, feeding a […]
Heart checkup for anteaters
Technology has evolved enough to identify animals, understand their habitats and track their movements. But understanding how environmental factors are physiologically causing stress to animals is still a challenge. Scientists at the Smithsonian are now deploying tiny cardiac monitors to study how 27 species, including anteaters in Brazil, are affected by changes in the environment. […]
After a hiatus, an endemic plant bursts into life in Sri Lanka’s central hills
- Sri Lanka’s highlands burst into violet, pink and white carpets as endemic Strobilanthes shrubs, locally known as nelu, begin to bloom in a synchronized manner, set seed and die, creating a breathtaking but fleeting display.
- The mass flowering overwhelms seed predators and attracts pollinators, boosting survival and reproduction — a rare evolutionary adaptation in the island’s montane ecosystem.
- Thousands of visitors flock to Horton Plains in the Central Highlands during the flowering season, raising risks of trampling, soil compaction, litter and disturbance to wildlife.
- Invasive plants such as mistflower (Ageratina riparia) and blue stars (Aristea ecklonii) could colonize areas left vacant after the bloom, potentially affecting future nelu cycles.
An invite to the tapir toilet buffet (cartoon)
The tapir’s role as a keystone species includes seed dispersal, ecosystem engineering, and … feeding the forest with its poop! Tapirs have been found to defecate regularly in shared toilet spaces called “communal latrines”, which become important feeding sites for a myriad species like squirrel, tinamou, thrushes and wood quails.
As Singapore heats up, pests are seeking refuge indoors
- In the past few years, previously spotless air-conditioned icons of Singapore such as Changi Airport and the Apple Store have experienced infestations and diseases on indoor greenery.
- Experts say the rise in extreme temperatures as the city-state loses forest cover explains the migration of flies, bees, butterflies and rats into cooler indoor environments.
- Singapore’s pest control industry is booming as a result, with the country’s National Environment Agency mandating tougher rules to curb vector-borne diseases.
- Methods used to control pest species are being challenged by animal welfare groups concerned over the growing use of glue traps, which catch protected as well as target species.
Octopus farming is a dangerous detour for marine conservation (commentary)
- Proponents of octopus farming claim it can reduce fishing pressure on wild octopus populations by supplying the seafood industry, and even suggest that these efforts could contribute to restocking wild populations in the future.
- In reality, they have a poor feed conversion rate, requiring a large amount of wild-caught marine protein to produce a relatively small amount of octopus, which risks exacerbating, rather than easing, pressure on wild fish populations and marine ecosystems that depend on them, the author of a new op-ed argues.
- “Octopus farming is a dead end masquerading as a solution. It does not address the root causes of wild population declines — it compounds them. The global community must resist the temptation to exploit another wild species under the guise of sustainability,” the author writes.

Counting kings: How annual lion surveys reveal the health of Africa’s protected areas (commentary)
- Lions are more than charismatic megafauna shaping the balance of species in the savannah food web. As such, their presence or absence can tell us a lot about the health of an ecosystem.
- Annual lion surveys offer a disciplined way to pair concern with action, writes Jon Ayers, board chair of wild cat conservation group Panthera and major supporter of lion conservation.
- Such surveys do not guarantee recovery. They make it possible to know, sooner and more accurately, whether recovery is under way.

Long-lost white shark tag traces remarkable journey from South Africa to SE Asia
- The discovery of a satellite tag from a subadult female white shark in Indonesia marks the first recorded connectivity of white shark movement between South Africa and Southeast Asia.
- The white sharks found in South Africa and Australia belong to different genetic pools, which makes the two populations distinct from one another, even though they share the same migratory route.
- The biggest threats facing white sharks in South Africa and Indonesia are unsustainable fishing, where the sharks become both the bycatch and main catch.
- While there are attempts to support local fishers to pioneer shark conservation instead of hunting them, such efforts are thwarted by lack of funding.
When does beaver reintroduction make sense?
- California has recently relocated beavers from spots where they were causing problems, like flooding, to tribal lands in Northern and Southern California.
- Many advocates say that relocating beavers to areas where they once existed brings back “ecosystem engineering” benefits to the landscapes they live in.
- But experts also caution that while beavers can help with fire resilience and improve water quality, they are only part of broader solutions to climate change and watershed restoration.
- Beaver advocates also note that learning to coexist peacefully with beavers is critical, both for the recovery of the species and for the ecosystem services they provide.
Mongabay shark investigation cited in motion to ban Brazil fin exports
Brazil’s top environment council cited a recent Mongabay investigation as it weighed a ban on shark fin exports and the use of wire leaders, a type of industrial fishing gear, within marine protected areas, Mongabay staff writer Karla Mendes reported. Brazil’s National Environmental Council, known as CONAMA, voted in favor of recommending a ban for […]
Animals that spread seeds are critical for climate solutions
- New research analyzing more than 3,000 tropical forest sites reveals that areas with fewer seed-dispersing animals store up to four times less carbon than forests with healthy wildlife populations.
- The study found that 81% of tropical trees rely on animals to disperse their seeds, establishing an ancient partnership now threatened by human activities such as deforestation, road construction, and hunting.
- Researchers mapped global “seed dispersal disruption” and found it explains a 57% reduction in carbon storage potential across proposed forest restoration areas.
- The findings demonstrate that protecting wildlife and addressing climate change are interconnected challenges, with conservation strategies like wildlife corridors and species reintroduction offering approaches that serve both biodiversity and climate stability.
Pet sharks have become cool, but is owning them ethical?
- Owning a shark and keeping it in a home aquarium has become cool — and it’s no longer just the province of tech bros and celebrities.
- But experts note that most home aquariums are inadequate and can lead to stunted growth, deformities and early death.
- Yet sharks are often easy to buy, with some selling for as little as $90 online; zebra sharks (Stegostoma tigrinum), which are endangered, go for around $6,000.
Mass vulture poisonings expose need for cross-border action in Southern Africa
- A cluster of mass vulture poisonings in May and June 2025 has drawn attention to an ongoing problem in the transfrontier conservation area that straddles South Africa, Zimbabwe and Mozambique.
- The field response to the poisonings involved teams of veterinarians, rapid response teams, and stepped-up monitoring of the area, saving the lives of more than 80 vultures.
- The series of incidents triggered meetings involving South Africa National Parks, conservation NGOs and other authorities to assess where systems were lacking and could be improved.
- Experts say national strategies to address poisoning and strengthen vulture conservation need to be complemented by regional action.
Poisoning crisis could drive vulture extinction in South Africa’s Kruger region
- More than 400 vultures died in a spate of poisoning events in and near South Africa’s Kruger National Park in May and June this year.
- André Botha, co-chair of the Vulture Specialist Group at the IUCN, says more than 2,000 vultures have been poisoned in the wider Greater Limpopo Transfrontier Conservation Area (GLTFCA) since 2015, and other raptors and predators have also died.
- Observers have noted an increase in hunting and snaring of species such as impala for the bushmeat trade, with poachers frequently leaving poison-laced carcasses behind to deliberately kill carnivores or vultures.
- Botha and others stress that urgent action is needed to rein in poisoning and wildlife crime in the GLTFCA, particularly preventative engagement with communities.
An ancient Indigenous civilization endures beneath an Amazon urban soy hub
- Ocara-Açu, a vast precolonial Amazon settlement, underlies the modern-day city of Santarém in Brazil, once serving as the core of a regional network that may have housed up to 60,000 people before the invasion of Europeans.
- Occasionally, Santarém’s rich Indigenous heritage surfaces through the cracks in the urban concrete, although archaeological sites have disappeared as a result of urban expansion, agriculture, and the construction of a soy terminal by commodities giant Cargill.
- Archaeological discoveries in the Santarém region challenge the long-held belief that the Amazon was too harsh to sustain large, complex human cultures, revealing a radically different urban paradigm.
Beavers restored to tribal lands in California benefit ecosystems
- In 2023, California relocated beavers for the first time in more than seven decades.
- The state’s wildlife agency partnered with Native American tribes to move beavers from places where they were causing problems, such as flooding, to parts of their former range.
- The moves and the state’s broader beaver restoration program are the result of decades of advocacy to change an adversarial relationship to one focused on beaver conservation and the benefits beavers can provide, from increased fire resilience to more consistent water supplies.
- The change in mindset involved education and coexistence campaigns, as well as correcting long-held misconceptions about the limited extent of the beaver’s former range in California.
As forest elephants plummet, ebony trees decline in Central Africa’s rainforests
- In the past three decades, poaching has decimated Africa’s now-critically endangered forest elephants, and as a result, their vital role as seed dispersers of many forest plants has been disrupted.
- A new study from Cameroon provides the first direct evidence that without forest elephants, there are fewer ebony saplings; on average, as few as 68%, in Central African rainforests.
- Researchers found that seeds pooped out in elephant dung have a better chance of surviving and sprouting as they are protected from hungry rodents and other herbivores that chew and destroy the seeds.
- The findings show that losing key ecosystem engineers and seed dispersers has far-reaching ecological and economic impacts, potentially altering entire ecosystems.
Rare Javan leopard sighting renews focus on conservation, monitoring efforts
- A rare Javan leopard was recorded on camera in Mount Lawu forest, Central Java, after officials installed camera traps following a hiker’s report.
- The endangered big cat’s presence highlights Mount Lawu’s ecological importance, where Tahura Mangkunagoro park conserves diverse plants, birds and mammals.
- With only around 350 Javan leopards left in the wild, the sighting underscores urgent threats to the species from habitat loss, hunting and human pressure.
- Authorities and conservation groups are expanding camera-trap surveys and preparing a 2026–2031 action plan to safeguard the species through better monitoring, habitat protection and community engagement.
Are crows really street smart? Science confirms the genius of corvids (commentary)
- Crows and other corvids exhibit remarkable intelligence — including tool use, problem-solving, memory and even social awareness — challenging long-held assumptions that such cognitive abilities are exclusive to humans or primates.
- Scientific research and experiments, some inspired by popular fables about clever crows, show that these birds understand cause and effect, plan for the future, and adapt their behavior based on context, environment and who’s watching.
- Urban crows thrive due to cognitive flexibility, as shown in an ongoing experimental project in India, which highlights their strategic foraging, memory and ability to learn and adapt in human-dominated environments.

Learning to live with lions: Interview with Claw Conservancy’s Andrew Stein
- An automated, real-time alert system is helping local communities in Botswana protect their cattle from approaching lions.
- A team at the nonprofit Claws Conservancy is also working with communities to name individual lions in order to help them build a connection with the animals.
- The initiative was launched to mitigate human-lion conflict, which often led to loss of livestock and the retaliatory poisoning of the lions.
- The lack of vehicles and torches, however, continue to be hurdles when it comes to effectively responding to alerts, which tend to come at night, when the lions are most active.
It’s time to update the language of human-wildlife interactions (commentary)
- A new op-ed explains how language shapes the way we view wildlife and their conservation, as even subtle word choices can drive perceptions of species or situations.
- Some terms commonly used to describe peoples’ interactions with wildlife like “human-wildlife conflict,” “crop-raiding” and “pest” are detrimental to the understanding of animals and their conservation.
- “There’s no denying that there will be situations when human and wildlife interests collide, but we can take a step back, consider the power differential between ourselves and other animals, and take a more sympathetic view of these problems,” the author argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.
Seed-dispersing animals are in decline, impacting forests and the climate: Study
A lot of attention has been paid to the decrease in bee populations and other pollinators, but a recent review article makes the case that we should be equally alarmed by the declining numbers of seed-dispersing animals, which are crucial for growing healthy forests. “Both are important and should be taken into account in restoration […]
Cockatoos have at least 30 impressive dance moves: Study
Scroll through social media, and you’re sure to find videos of cockatoos swaying rhythmically to music. Scientists studying these impressive dance moves report in a recent study that at least 10 cockatoo species dance, sharing at least 30 distinct dance moves between them. Cockatoos are a family of parrots, which are highly intelligent birds. Many […]
Can we undo extinction? A growing effort to restore lost sharks
- ReShark is the world’s first shark rewilding program, aiming to restore Indo-Pacific leopard sharks to reefs where they’ve disappeared, starting in Raja Ampat, Indonesia.
- The initiative repurposes surplus eggs from aquariums, transporting them across oceans and rearing them in locally managed hatcheries before releasing them into the wild.
- A growing community of Indonesian conservationists—including trained “shark nannies,” students, and villagers—is central to the project’s success and sustainability.
- With global collaboration and scientific rigor, ReShark aims to produce a model for reversing extinction—one grounded in genetics, local stewardship, and public engagement.
Eswatini’s young honey-hunters sustain a rare bond with wild birds
In Eswatini, the Southern African country formerly known as Swaziland, people still commonly hunt for honey with the help of wild birds, a new study finds. This rare form of human-wildlife cooperation, which has disappeared from much of Africa, is expected to endure in Eswatini, sustained by tradition and peer-to-peer learning, researchers say. Only in […]
Wolves’ continued spread in California brings joy, controversy & conflicts
- After nearly a century’s absence, gray wolves continue to recolonize California, bringing changes and challenges to the state and its inhabitants.
- Ongoing research and monitoring programs are helping scientists understand growing wolf populations and their impact on prey species, other predators and alterations to the landscape.
- Gray wolves in California are protected under both federal and state laws. But balancing conservation, livestock predation and public safety concerns is complicated.
- The state has formulated a management plan for wolves: a compensation program for ranchers who lose livestock to wolves and efforts to mitigate conflicts.
Rare monkeys cross new sky bridges
Hundreds of monkeys can now safely cross roads in Alta Floresta, a city in the southern Brazilian Amazon. Seven canopy bridges have reconnected rainforest fragments that were separated by urban roads. Camera traps have recorded more than 3,000 crossings by canopy-dwelling wildlife, an average of more than 12 a day, since October 2024, when the […]
First record of Cape clawless otter preying on African penguins: Study
The critically endangered African penguin has several predators to fear, including gulls, seals and sharks at sea, and leopards, caracals, domestic dogs and mongoose on land. A recent study has now documented the first confirmed case of yet another predator: a Cape clawless otter was observed preying on the African penguins of a mainland colony. […]
Domestic cats pose interbreeding threat to little known wildcat ancestor
Domestic cats are hugely popular as pets, yet little is known about their ancestor, the Afro-Asiatic wildcat. This species, Felis lybica, is the most widely distributed wildcat in the world, but experts still don’t know its exact population. The wildcat faces several threats to its survival, including interbreeding with domestic cats and the diseases they […]
Orangutans make up for lost sleep with daytime naps, study finds
- New research based on more than a decade of field observations indicates that wild Sumatran orangutans balance their sleep needs much like humans do, by napping during the day.
- The team found the shorter an individual’s sleep period overnight, the longer was its cumulative nap period the next day.
- Orangutan sleep also varied with temperature, activity levels and proximity of others, indicating the great apes have to trade off between foraging, socializing, traveling and sleep.
- Deforestation, habitat fragmentation and climate change are all likely to influence the capacity of orangutans to manage their sleep needs, with clear consequences for their overall health and survival.
Nepal launches action plan to boost endangered dhole conservation
Once widespread throughout much of Asia, the wild dog known as the dhole has disappeared from more than 75% of its historical range, according to the IUCN, the global wildlife conservation authority. In Nepal, there are an estimated 500 dholes (Cuon alpinus) remaining, but recent sightings suggest they may be making a comeback. This has […]
Videos capture an unlikely alliance between ocelots and opossums in the Amazon
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. In the Peruvian Amazon, a series of curious encounters has left biologists scratching their heads. Camera traps have captured an unexpected partnership: solitary, nocturnal ocelots (Leopardus pardalis) strolling alongside common opossums (Didelphis marsupialis). Not once, but four times, […]
Conservationists raise sharks to restore reefs in waters around Thailand
- A new rewilding program aims to boost the local population of bamboo sharks in the waters of Khao Lak, Thailand.
- The species, classified as near threatened on the IUCN Red List, used to be abundant in the area, but has declined as a result of overfishing and habitat destruction.
- Since the project launched in 2018, with the support of luxury resorts in the area, it has released 200 bamboo sharks into the wild.
- A separate program that started in May 2025, is breeding leopard sharks, which are listed as endangered. They will be released in the waters off Phuket, and eventually the Gulf of Thailand.
Deforestation in the Philippines may have caused infertile hybrids of endemic frogs, study finds
- The truncate-toed chorus frog is a widely distributed species in the Philippines archipelago, with four distinct subspecies. One of them, the Leyte chorus frog, first described around 80 years ago, is considered a rare, enigmatic and morphologically distinct subspecies that has not been seen for nearly half a century since its first sighting.
- In a recent study, scientists used genetic analysis to find that the subspecies is, in fact, a hybrid between another subspecies of the truncate-toed chorus frog and a ground-dwelling, closely related slender-digit chorus frog.
- Researchers say this infertile hybrid is a result of large-scale deforestation in the Philippines, which forced tree-dwelling frogs to come on land, where ground-dwelling frogs “ambushed” and mated with them, creating the hybrid.
- Conservationists say this hybrid shows how human-caused disturbances impact biodiversity in the Philippines, where deforestation is rampant due to mining, logging and expanding agriculture.
Tropical forest roots show strain as changes aboveground filter below
- Tropical forest plant roots have not received as much research attention as aboveground vegetation. This knowledge gap affects our understanding of how rainforests adapt to change, including their ability to capture and store atmospheric carbon.
- An emerging field of research is looking at how root systems respond to global change. New evidence dramatically underlines the outsized importance of tropical forests in the global carbon cycle. Tropical forests represent one of the world’s largest carbon sinks, largely thanks to plant roots, which add carbon to soils.
- Despite the challenge of studying tiny roots hidden underground, researchers are uncovering important insights. Some tropical forests send roots deeper into the soil under dry conditions, possibly seeking moisture, which may aid in drought tolerance. Others seem unable to do this, making them more vulnerable to climate change.
- Recent plant root studies are confirming the immense stress tropical rainforests are under, with conditions changing faster than roots belowground can adapt. Knowing more precisely which forests can, and can’t, tolerate escalating climate change and other stressors could better inform management and conservation decisions.
Sheila Colla, advocate for bees, died on July 6th, aged 43
- In 2009, Sheila Colla spotted Canada’s last known rusty-patched bumblebee, a discovery that marked the culmination of years of fieldwork and a lifelong commitment to pollinator conservation.
- A pioneering scientist and professor, Colla warned early about the decline of native bees—long before it became mainstream—and translated complex research into action for policymakers, citizens, and children.
- Through bestselling books and the Bumble Bee Watch citizen-science platform, she mobilized tens of thousands to protect North America’s wild bees, emphasizing their solitary, vital, and often overlooked roles.
- Colla’s legacy lives on not only in ecological science but in the inclusive community she built—opening doors for marginalized voices in science and championing justice until her final days.
Canada’s Pacific Coast hit hard by trawling, with limited transparency: Report
- Trawling vessels pursuing fish are damaging marine ecosystems in Canada’s West Coast waters and could be operating illegally in some cases, and yet they work with insufficient transparency, a new NGO report says.
- Nine large trawlers have together trawled swaths of the ocean collectively larger than the size of Ireland since 2009; they have likely trawled in prohibited zones at least 47 times and have disrupted Chinook salmon (Oncorhynchus tshawytscha) migratory routes, which are foraging areas for an endangered population of killer whales (Orcinus orca), the report says.
- A trawling industry group dismissed the NGO’s findings, saying they lacked context and the fishery was very well regulated.
- A Canadian regulatory agency said the fishery was well managed, with strict monitoring and enforcement of rules.
Sharks didn’t rebound—so Mark Erdmann is putting them back
- For over 30 years, Mark Erdmann has combined scientific discovery with grassroots conservation in Indonesia, helping communities protect their reefs from destructive practices and documenting more than 220 new species.
- As a leader behind Raja Ampat’s pioneering community-governed marine protected areas, Erdmann has shown how local stewardship can revive ecosystems—bringing back sharks, rays, and sustainable tourism.
- Despite new threats like over-tourism and revived mining, Erdmann remains hopeful, pointing to rising public resistance, tech-enabled rewilding programs like ReShark, and a new generation of Indonesian conservationists.
- Erdmann spoke with Mongabay Founder and CEO Rhett Ayers Butler during a voyage in the Pacific in June 2025.
The aardvark and the melon (cartoon)
Camera trap footage and scent analysis confirm a unique symbiosis between an ant-eater and a subterranean fruit. Looks like the ant-eating aardvarks of the African savanna do not need to be taught the benefits of a balanced diet! Study confirms that ant-eating aardvarks have a craving for buried melons

Giant river otter returns to Argentina after almost four decades
A family of giant river otters was released into the Iberá National Park in northeast Argentina on July 1. The endangered species, with no known breeding populations in Argentina over the past 40 years, was considered probably extinct in the country. The release, led by conservation nonprofit Rewilding Argentina, included a breeding pair named Coco […]
Assisted colonization could be our ally in adapting to climate change, study suggests
- As climate change rapidly transforms ecosystems, it threatens to wipe out vital species, potentially leading to ecosystem collapse.
- Islands, to which many species from elsewhere can’t disperse naturally, are particularly vulnerable to these threats.
- In a recent study, scientists argue that assisted colonization, where species from neighboring regions are introduced to better cope with the changing climate, could help the forests of Great Britain adapt to the rapidly changing climate.
- Some conservationists say that assisted colonization is a proactive way of thinking about conservation in a changing world, rather than more reactive approaches such as species reintroductions.
Bogong moths use stars and the Milky Way to make epic migration
In Australia, millions of newly hatched Bogong moths embark on an impressive journey twice a year. Each spring, they hatch from eggs in their breeding grounds in Australia’s southeast and fly up to 1,000 kilometers (621 miles) further southward to spend a few months in the cool caves of the Australian Alps — a place […]
Nepal launches plan to boost science, awareness to save dholes
- Nepal has launched its first-ever species-specific action plan for dholes (Cuon alpinus), allocating 262.9 million rupees ($1.9 million) over five years to address key threats such as habitat loss, prey depletion, disease and competition with larger predators.
- The plan prioritizes both scientific research and public awareness, with the highest budget shares going to understanding dhole distribution (25%) and conservation education (26.4%), highlighting a dual strategy of data-driven conservation and local engagement.
- A key innovation is the financial model, which leverages 36% of the funding from existing conservation plans for tigers and snow leopards — species that often share habitats with dholes but may also displace them.
Friendship benefits male and female mountain gorillas differently, study shows
- A 21-year study of 164 wild mountain gorillas found that strong social bonds produce different health effects for males and females, with males experiencing more illness but fewer injuries when they have close friendships.
- Female gorillas with strong social bonds generally had better health outcomes, experiencing 19% fewer injuries and 14% less illness compared to those with weaker social bonds.
- The benefits and costs of friendship varied based on group size, with females in small groups having fewer offspring despite better health, while those in large groups had more babies but higher rates of illness.
- The research helps explain why animals exhibit such diverse social behaviors and may inform conservation efforts for this endangered species, which numbers just over 1,000 individuals.
Orcas discovered making tools from seaweed to ‘massage’ each other
- Southern resident killer whales in the Salish Sea off the U.S. state of Washington have been observed making tools from bull kelp stalks, biting off pieces and using them to massage each other in a behavior scientists call “allokelping.”
- This represents the first documented evidence of toolmaking by marine mammals, with whales of all ages participating in coordinated grooming sessions that likely serve both hygiene and social bonding purposes.
- The behavior helps whales exfoliate dead skin and may provide antibacterial benefits, though the endangered population of only 73 individuals faces multiple threats including declining food sources and habitat destruction.
- The bull kelp forests where whales source their grooming tools are also threatened by warming oceans, making conservation of both the whale population and their kelp habitat crucial for preserving this unique cultural behavior.
Longhorn crazy ants use ‘swarm intelligence’ to clear path obstacles
Longhorn crazy ants, named for their jerky and erratic movements, may seem chaotic, but they are actually very cooperative and efficient at retrieving food. A new study shows that through intelligence of the swarm, worker ants are able to anticipate obstacles and clear them from a path so other ants can more easily move bulky […]
As large scavengers decline, disease risk soars, study finds
Scavengers aren’t the most charismatic of animals, but they perform a vital task: by eating carrion, they remove dead animals from our environments. Yet large-bodied scavengers are declining worldwide, increasing the risk of the spread of diseases, according to a recent study. Researchers found that 1,376 animal species have been recorded in the scientific literature […]
When heat waves hit, clownfish shrink to survive, study finds
- Clown anemonefish (Amphiprion percula) have a surprising survival strategy: they shrink in length — not just lose weight — to survive marine heat waves and avoid social conflicts, boosting their heat wave survival odds by up to 78%, a new study finds.
- Researchers tracked 67 breeding pairs of clownfish in Papua New Guinea through a severe marine heat wave, measuring fish size repeatedly and finding that synchronized shrinking between mates helps maintain social hierarchies and improves survival chances.
- The study raises bigger questions about whether this shrink-to-survive mechanism is widespread among fish, potentially explaining global trends of shrinking fish sizes amid climate change, and calls for controlled lab experiments to uncover the physiological causes.

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 […]
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 […]
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 […]
To collect native seeds, Ugandan botanists are climbing forest giants
- To access the best seeds for the propagation of native species, botanists often need to safely and sustainably collect from a variety of mother trees.
- In Uganda, Sebastian Walaita at the Tooro Botanic Gardens has been honing his skills and training botanists in high tree climbing for more than 25 years.
- These skills allow the botanists to collect seeds from even the tallest trees, in a way that captures genetic diversity.
- In October 2024, Walaita and a fellow Ugandan held a training in high tree climbing and seed collection in Côte d’Ivoire.
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.
New map highlights complex web of marine migrations
- Scientists have launched a new database on marine migratory patterns to address gaps in the knowledge of policymakers and conservationists.
- The Migratory Connectivity in the Ocean (MiCO) database pulled data from 1,300 existing studies in the scientific literature to describe the migratory patterns of 109 mammal, bird and fish species.
- The database highlights the interconnected nature of marine migrations, and underscores the need for cross-border collaboration in conservation efforts.
How Costa Rica’s ranchers contribute to jaguar and puma conservation
Ranches in Costa Rica occasionally overlap with jaguar and puma hunting areas, creating conflict that can sometimes be unavoidable. But with the help of conservationists, ranchers are now able to prevent both cattle and predator deaths, Mongabay contributor Darío Chinchilla reported for Mongabay Latam. In communities like Lomas Azules, when a jaguar (Panthera onca) or […]
Without vultures, carcasses are slow to rot and disease-carrying flies abound
- Researchers in Costa Rica found that pig carcasses decomposed twice as fast when vultures had access to them compared to carcasses where vultures were excluded.
- The absence of vultures led to a doubling of fly populations at carcass sites, which could affect human health, since these flies can carry diseases like botulism and anthrax, and antibiotic-resistant bacteria.
- Unlike temperate regions with diverse scavenger communities, the neotropical forest system showed vultures as the primary vertebrate decomposers, with few other animals eating carcasses.
- The study highlights a major research gap since neotropical vultures are represented in only 7% of existing vulture literature, despite facing similar conservation threats as Old World vultures, like habitat loss, poisoning and power line collisions.
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.
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 […]
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 […]
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.
Cape vulture conservation offers hope, but challenges remain
- The Cape vulture, Southern Africa’s only endemic vulture species, has shown positive signs of recovery in some parts of its range, with the overall population stabilizing.
- In 2021, the species’ conservations status improved from endangered to vulnerable, making the Cape vulture a rare success story for vulture conservation in Africa, say conservationists.
- Despite this success many challenges remain in protecting this species and other vultures due to threats such as poisoning, energy infrastructure and, increasingly, “belief-based use.”
- The recovery of the Cape vulture provides a positive example for vulture conservation, but replicating this success with other species is riddled with challenges, say experts.
The Great Whale Conveyor Belt (cartoon)
While migrating between their feeding and mating grounds, baleen whales transport massive amounts of nutrients across latitudes. This phenomenon is termed “The Great Whale Conveyor Belt”, prompting scientists to argue that whale conservation can help improve the resilience of global marine ecosystems.
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 […]
Ground-level ozone wreaks havoc on warming planet
Ozone as a layer several kilometers up in the atmosphere protects living beings, including humans, from ultraviolet rays. But its accumulation at ground level can be very dangerous, Mongabay contributor Sean Mowbray explains in an article published in April. Ground-level, or tropospheric, ozone forms when methane, nitrogen oxides, carbon monoxide and volatile organic compounds react […]
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.
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 […]
‘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.
Study suggests there are more jaguars in the Amazon than previously thought
Jaguar numbers in the Amazon Rainforest may be higher than previous estimates, according to a new large-scale study that offers the most comprehensive population snapshot to date. Using camera-trap images of jaguars (Panthera onca) across the Brazilian, Colombian, Peruvian and Ecuadorian Amazon, researchers calculated an average density of three jaguars per 100 square kilometers (about […]
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 […]
Fishing cats misunderstood, misidentified in Nepal’s Kapilvastu
- Fishing cats in Nepal are often misunderstood and mistaken for leopards or blamed for fish losses, leading to retaliation and conflict with fish farmers.
- Surveillance measures like CCTV and myths have fueled fear and misinformation, despite little evidence showing fishing cats as major threats to aquaculture.
- A conservation initiative called “fish banks” tried to reduce conflict by compensating farmers with fish instead of money but had mixed results and eventually lost funding.
- Experts emphasize the need for science-based conservation, better population data and public education to protect fishing cats and promote coexistence in human-altered landscapes.
An interview with orangutan conservationist and advocate Gary Shapiro
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. Orangutans, with their expressive eyes and human-like behaviors, have long fascinated us. Few people, however, have delved as deeply into their world as Gary L. Shapiro. His five-decade career began with a groundbreaking study in primate communication, where […]
In West Africa, hooded vultures vanish as abattoirs modernize
- For centuries, hooded vultures in West Africa have lived in close association with people in towns and cities.
- The vultures’ dependence on scraps thrown out has grown in line with the overhunting of large-bodied mammals in the wild.
- But changes in the way these scraps are disposed of at slaughterhouses in many districts appears to be impacting the vultures.
- The birds now face fierce competition from feral dogs, and from people who harvest slaughterhouse waste to feed their livestock.
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
When a 5.2-magnitude earthquake shook the U.S. city of San Diego on April 14, a video showing five African elephants huddling together in the middle of their enclosure at San Diego Zoo Safari Park made headlines. It showed three older female elephants, Ndlula, Umngani and Khosi, moving quickly to protect 7-year-old calves Zuli and Mkhaya. […]
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.
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 […]
Coexistence with Europe’s carnivores is possible (commentary)
- The return of bears, wolverines, lynx and wolves to European landscapes from where they have been absent for decades, or even centuries, is a conservation success.
- But while this has also led to a resurgence of age-old conflicts, such as livestock depredation and fears for personal safety, the author of a new op-ed who leads a research project aimed at coexistence is optimistic.
- “The Co-creating Coexistence Project [will] provide valuable knowledge to guide policy as the focus shifts from ‘how do we prevent large carnivores from going extinct?’ to ‘how to live with a conservation success?’” he writes.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Snared, skinned, sold: Brutal March for Indonesia’s Sumatran tigers
- Police in Indonesia charged at least 11 people in the month of March with wildlife crimes after a tiger was butchered in Riau province and alleged traffickers were found with body parts in the semiautonomous province of Aceh.
- In West Sumatra province, conservation officials successfully trapped a young female tiger whose leg had previously been amputated, likely in a snare trap.
- Sumatran tigers are a critically endangered subspecies of tiger and fewer than 400 are believed to remain in the wild.
How cultural and religious beliefs combine for snow leopard conservation (commentary)
- “Deep-rooted cultural beliefs and legal protections continue to play a crucial role in safeguarding snow leopards, supported by awareness campaigns that reinforce traditional practices and conservation,” a new commentary explains.
- In many areas across their range where livestock are killed by the rare predators, farmers’ religious customs often dictate that they must not harmed in retaliation.
- This article is a commentary. The views expressed are those of the author, not necessarily Mongabay.
Kanzi the bonobo redefined what it means to be human
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives, and story summaries. Few apes have done more to unsettle human certainties than Kanzi the bonobo. He wasn’t the first nonhuman primate to use symbols to communicate, but he was the first to do so with such fluency, subtlety and apparent […]
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
Venom isn’t just a feature of some animals; it’s found across the living world, from plants and fungi to bacteria and viruses, says a new study. Lead author William Hayes, an ecologist at Loma Linda University, U.S., has long studied venomous rattlesnakes. It was while teaching a course on the biology of venom that he […]
The newest wildlife crime-fighting superheroes in town (cartoon)
You might think that ‘hero rats’ are the lead characters of a new Pixar movie, but these happen to be actual African Giant Pouched Rats, trained by the organization APOPO. Their prolific portfolios include detection of landmines, tuberculosis and wildlife contraband, helping nab illegal trafficking and smugglers at East African ports! Meet the giant rats […]
Chain-link fencing protects livestock from big cat attacks in Tanzania: Study
- Livestock farmers in the environs of Ruaha National Park in Tanzania have to remain vigilant at night to protect their animals from lion and leopard attacks in an area hosting 10% of the world’s wild lions.
- But a study reveals that fortified enclosures in neighborhoods can protect livestock from carnivore attacks, benefiting both the owners and their neighbors.
- Researchers discovered that predators avoid neighborhoods when pastoralists construct corrals using chain-link fencing, a more effective method than traditional African boma fences made of thorny bushes.
- Carnivores in neighborhoods with multiple enclosures face “more work,” making it difficult to pull animals out. The fences reduce availability and attractiveness, leading carnivores to avoid neighborhoods with high-density fortifications, according to Jonathan Salerno, the study’s lead author.
Indiscriminate pesticide use threatens Bangladesh honey bees
- In Bangladesh, honeybee populations are dwindling as unaware farmers use insecticides, particularly neonicotinoids, which disrupt their foraging and survival.
- Experts are seriously concerned about the use of chemical cocktails comprising neonicotinoids without extensive research.
- Despite worldwide concerns over neonicotiniods, Bangladesh authorities are yet to address the issue due to lack of awareness.
How Peruvian cockfighters could tip the scales for endangered sawfish
- In Peru, where cockfighting is not only legal but regarded as an important cultural practice, cockfighters have long brought their roosters to fight wearing sharp spurs fashioned from the “teeth” of sawfish.
- The largetooth sawfish (Pristis pristis), the only sawfish that lives in Peru, is incredibly rare and considered critically endangered.
- Advocates for the species both within and outside the sport have increasingly realized that cockfighting plays a role in preventing or hastening its demise in Peru and are working to eliminate sawfish spurs from the sport.
- Although trade in sawfish parts is now illegal in Peru, times are tough for the country’s artisanal fishers. Experts worry that demand for sawfish spurs could drive more sawfish killings than the species can support.
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.
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.
Fishing cat home range far bigger than previously thought, Nepal study suggests
- A GPS-collaring study in southeastern Nepal found that fishing cats could have much larger home ranges than previously recorded.
- Contrary to popular belief among local communities, some fishing cats were found to inhabit human-dominated landscapes, rather than only visiting them at night.
- Researchers suggest that low prey density in Nepal’s Koshi Tappu Wildlife Reserve and more accurate GPS tracking may explain the larger home ranges observed.
- The study highlights the need for community engagement in conservation, as fishing cats help control rodent populations and face threats from habitat loss and human-wildlife conflict.
How one woman’s wolf ‘moon shot’ changed Yellowstone forever: Interview with director Tom Winston
- A new documentary film, “Mollie’s Pack,” tells the story of the then-head of the U.S. Fish and Wildlife Service, Mollie Beattie, and the controversial, but ultimately triumphant, restoration of wolves to Yellowstone National Park in 1995.
- The filmmakers were able to find and access lost footage to make a compelling and emotional film about success and loss.
- The restoration of wolves into Yellowstone was a “moon shot” moment, according to director Tom Winston.
- Winston says the reintroduction of wolves to Yellowstone will be “a motivating factor” for future rewilding initiatives around the world.
In a seasonally flooded Amazon forest, jaguars take to the trees
- A recent study has confirmed that Amazon jaguars have developed a fascinating strategy to face seasonal river flooding: when the waters rise and flood the forests, these felines begin to live up in the trees.
- The finding, made in the Mamirauá Sustainable Development Reserve in Brazil’s western Amazon, surprised researchers who initially thought the animals would migrate to dry lands in search of prey.
- The research monitored 14 jaguars fitted with GPS collars between 2011 and 2020; the data showed the home range of these animals during floods remained virtually unchanged from during the dry season.
- While this adaptation is unique to Amazon jaguars, experts warn that variation in rain and flood cycles, aggravated by climate change, may pose yet another threat to this already near-threatened species.
Sweden to kill 87 Eurasian lynx despite complaints to EU Commission
Sweden has issued licenses to hunters to kill 87 Eurasian lynx between March 1 and Apr. 15. Conservation organizations say the annual hunts of the medium-sized wildcat violate environmental legislation of the European Union, of which Sweden is a part. The Eurasian lynx (Lynx lynx) is categorized as vulnerable on Sweden’s red list, but the […]
Elusive wildlife shows up for photographer’s camera traps in Congo
- Photographer Will Burrard-Lucas deployed high-definition cameras at four sites in the Republic of Congo’s Nouabalé-Ndoki National Park throughout 2023.
- The cameras captured a selection of beautiful photographs of seldom-seen wildlife.
- Nouabalé-Ndoki National Park is home to significant populations of endangered mammals, including gorillas, chimpanzees and forest elephants.
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, […]
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.
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.
Getting rewilding right with the reintroduction of small wildcats
- Four lynx were illegally released in Scotland earlier this year by an unknown party, sparking condemnation. One of the cats died shortly after capture. That release comes amid long-running discussions of a possible reintroduction of this wildcat to the United Kingdom.
- Conservationists are working to reintroduce small cats across the globe. There are about 40 recognized species of wildcats, including a handful of charismatic big cats and at least 33 small wildcat species — with some of the most threatened felid species numbering among them.
- Mongabay spoke to experts working on small cat recovery projects in various stages of progress to understand what can make small cat reintroductions successful.
- Small wildcat reintroductions are presently underway or under consideration on the Iberian Peninsula, in Scotland, Argentina, Taiwan, Brazil, South Africa, Thailand and elsewhere.
Meet the giant rats fighting wildlife trafficking
- Scientists are training the first generation of rats in Tanzania to detect illegal wildlife trafficked products.
- Their research shows that African giant pouched rats can locate concealed wildlife products such as pangolin scales, rhino horns and ivory in shipments.
- This innovative approach could reshape antitrafficking efforts and shed new light on the illegal wildlife trade.
Petition calls on EPA to tighten pesticide rules to protect bees
Insect conservation NGO the Xerces Society recently petitioned the U.S. Environmental Protection Agency to expand its requirement of data to evaluate pesticides can that hurt bees. Scientists say improving pesticide safety for bees would benefit many other pollinators, including the iconic monarch butterfly (Danaus plexippus), which was recently proposed for protection under the U.S. Endangered […]
Wild baboons don’t recognize their own mirror reflections
Humans like to study themselves in a mirror. But wild baboons, when presented with a mirror, don’t seem to recognize they’re staring at their own selves, a new study has found. For decades, researchers have tried to understand if other animals are self-aware. They’ve used what’s called the mirror test as a way to measure […]
The world’s kelp needs help — less than 2% is highly protected
- Kelp forests support a kaleidoscope of biodiversity and perform crucial ecosystem functions, yet they are in trouble globally.
- A recent journal commentary shows that just 15.9% of kelp forests are in protected areas, and only 1.6% of them are in areas with the highest levels of protection.
- The authors said they hope their findings will motivate policymakers to include kelp forests in international conservation targets, such as the “30×30” mandate to protect 30% of Earth’s land and sea by 2030.
Surge in rat numbers linked to climate warming, urbanization: Study
What’s new: Cities experiencing warmer temperatures, fewer green spaces and denser human populations are seeing a rise in rat numbers, a recent study shows. What the study says: Jonathan Richardson, a biology professor at the University of Richmond, U.S., and his colleagues wanted to check if anecdotal media claims about increasing urban rat (Rattus spp.) […]
Birds guide honey-hunters to most of their harvest in Mozambican reserve
- A new study reveals the economic importance of wild honeyguide birds to villages in northern Mozambique.
- Three-quarters of the honey collected by honey-hunters in Niassa Special Reserve is found with the help of the birds, a new study finds.
- Some of the honey is sold, underscoring the economic importance of the birds to families in a region where rates of hunger, poverty and unemployment are high.
- The human-honeyguide partnership remains strong in Niassa, unlike in areas with widespread beekeeping, and researchers see potential for honey-hunters to support conservation efforts.
Kenya revives poisoning campaign to curb invasive Indian house crows
- Indian house crows, introduced to East Africa in 1891, have become a major pest in Kenya, threatening native birds, spreading disease, damaging crops, and disrupting tourism.
- Kenya has revived a poisoning campaign using Starlicide, a U.S.-developed bird control poison, after a 20-year ban on its import; conservationists report increased small bird populations in treated areas.
- Experts support the poisoning as necessary, but critics argue for long-term solutions like regional cooperation and improved waste management to limit food sources.
- Conservationists warn the crows could spread further, including to Nairobi, and stress the need for a coordinated approach to control their rapid population growth.
Amazonian manatees are gardeners of the forests, research shows (cartoon)
Confirming a previously hypothesised role of the Amazonian manatee as a gardener of the forests, biologist Michelle Guterres’ study adds another cap to the already impressive portfolio of this gentle giant. Amazonian manatees are listed ‘Vulnerable’ on the IUCN Red list because of hunting, climate change, droughts and habitat loss. Banner image: Amazonian manatees at a rescue […]
Chimps remember, for years, the location of ant nests that provide food
- Multiple studies have indicated that wild chimpanzees rely on memory to find ripe fruit, but less has been known about what role memory plays in sourcing foods of animal origin.
- A recent study monitored ant-feeding behaviors in savanna chimpanzees in Senegal, concluding that the apes also rely on memory to locate underground ant nests, rather than simply stumbling across nests opportunistically.
- The chimpanzees were also observed using tools and multiple senses to determine whether ant nesting sites were inhabited.
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.
Study shows degradation changes a forest’s tree profile and its carbon storage
- In highly deforested landscapes and degraded forests, large-seeded big trees are losing out to opportunistic, fast-growing species, a recent study has found.
- Having examined 1,207 tree species across 271 forest plots in six Brazilian regions in the Amazon Rainforest and Atlantic Forest, the study shows that tree species normally dominating landscapes with a high forest cover seem to be in decline.
- The researchers suggest this is because the relatively large wildlife needed to disperse large seeds disappear early on from human-modified landscapes, allowing trees with smaller seeds, and thus smaller dispersers like birds, to dominate the forestscape.
- As forests become increasingly degraded, they lose their functional characteristics, as soft-wood, fast-growing trees have less ability to store carbon, are less resistant to fire and drought, and generally die younger.
The paradox of balancing conservation efforts for Himalayan wolves and snow leopards (commentary)
- Although snow leopards cause greater livestock losses than Himalayan wolves, human communities generally show greater tolerance and acceptance toward snow leopards.
- This ‘predator paradox,’ where the more damaging predator is more tolerated, leads to less conservation support for wolves and more for snow leopards.
- “Both snow leopards and wolves are crucial to the Himalayan ecosystem, but conservation has overwhelmingly favored snow leopards. This disparity in attention and resources amplifies the challenges faced by wolves, highlighting the need for a balanced approach to conserve both species effectively,” a new op-ed argues.
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.
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 […]
Atlantic puffins are perilously attracted to artificial light
- When they make their first journey into the ocean, fledgling Atlantic puffins are prone to being stranded on land, imperiling them. For years, scientists have wondered what leads to these strandings.
- A new study provides experimental evidence to show that artificial light lures young puffins toward land, contributing to strandings.
- The study found pufflings don’t have a strong preference for any particular light source or color. However, once stranded, they move more under darkness and high-pressure sodium lights than under LED lights.
- Reducing artificial lights along the coast and offshore could save puffin lives, say conservationists, as Atlantic puffin populations are decreasing in parts of Europe. It can also save other threatened seabirds, such as Leach’s storm petrel found off Canada’s coast.
Meet Africa’s most lethal cat: the black-footed cat
In this episode of Candid Animal Cam meet the African black-footed cat (Felis nigripes), one of the continent’s rarest and most lethal predators. Found only in South Africa, Namibia, and Botswana, this tiny feline is known for its remarkable hunting accuracy—striking its prey 60% of the time, far outpacing even tigers. However, despite her prowess, […]
The fuel that moves people: the Ecuadorian case
- In Ecuador, the main areas of colonization were a north-south corridor along the base of the Andes and the Sucumbíos-Orellana quadrant, the country’s major oil-producing region.
- Since the 1970s, populations in both areas have grown significantly. The Andean zone went from 160,000 inhabitants to more than 520,000 in 2017; in parallel, the population in the provinces of Sucumbíos and Orellana increased from less than 12,000 to more than 350,000.
- Colonization also led to the invasion of lands of the indigenous Shuar, which prompted an unusual effort on their part to protect their territory. Today, the area specializes in cattle production and seeks to establish a niche market for high-quality beef for the domestic market.
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.
Wisdom the 74-year-old albatross lays an egg with new mate
Wisdom, the world’s oldest known wild bird, has laid an egg, this time with a new partner. She is a Laysan albatross (Phoebastria immutabilis), or mōlī in Hawaiian, and this is her first egg in four years, the U.S. Fish and Wildlife Service (USFWS) Pacific region said in a statement on X. “She did it […]
Bolivia’s internal colonization and its March to the East
- Bolivia’s current configuration and its final area were consolidated after the Chaco War and after the country ceded Acre to Brazil and its coastal provinces to Chile.
- Since then, the need to occupy vast territories allowed for wide-scale deforestation, especially in the Chapare and the alluvial plain of Santa Cruz.
- In the department of Santa Cruz, population grew from about 300,000 in 1960 to more than three million in 2022. Although 70 % of this growth has been concentrated in the metropolitan area of Santa Cruz de la Sierra, the urban economy continues to rely heavily on agriculture.
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.
Killer whales have found new homes in the Arctic Ocean, potentially reshaping marine ecology
- The vast ice sheets that historically kept killer whales out of the Arctic Ocean are melting as the region rapidly warms.
- Two small, genetically distinct groups of killer whales now live in the Arctic, after migrating from more southern regions of the Atlantic Ocean.
- Killer whales put pressure on the local ecosystem, including Arctic whales important to Indigenous groups.
‘Missing’ tigers in India: Tracking gaps or oversight?
A curious case of missing tigers in India’s Ranthambore National Park has raised concerns about how authorities monitor and update fluctuating tiger numbers, and how they define “missing,” contributor Deshdeep Saxena reports for Mongabay India.

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 […]
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.
Deforestation around Mennonite colonies continues in Peruvian Amazon: Report

Communities band together to save besieged reserve in Bolivia
- Bolivia’s Tucabaca Valley Municipal Wildlife Reserve has been beset by clearing and fires over the past several years.
- Now, mining, infrastructure development and land trafficking are adding to the pressure faced by the reserve.
- Residents of nearby communities have formed an association called Movement in Defense of the Tucabaca Valley.
- In June, a delegation from the Movement visited the Tucabaca reserve to assess the damage.
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.
A father and son duo fight invasive lionfish on a Honduran reef
- Live coral covers 68% of Tela Bay, on the northern coast of Honduras, creating a complex ecosystem that’s part of the wider Mesoamerican Reef system.
- Among stressors including overfishing and coral bleaching due to climate change, is the invasive lionfish — a spectacular-looking, venomous, striped fish native to the Indo-Pacific that, with no natural predators here, is wreaking havoc on marine ecosystems throughout the Caribbean.
- To protect Tela Bay’s embattled coral reef, a local father and son are mounting a single-minded lionfish hunting effort to limit the fishes’ spread, hunting the fish themselves and organizing hunting competitions.
