The Bornean ferret badger is a small carnivore with the slinky body of a ferret and a face mask like a badger. A new study confirms that it lives only in the mountains of Sabah, a Malaysian state on the island of Borneo.  Ferret badgers are nocturnal carnivores, widespread across Southeast Asia, but the Bornean ferret badger (Melogale everetti) lives only in a narrow mountain range on the island of Borneo. A group of researchers from the Bornean Carnivore Programme, part of the University of Oxford’s Wildlife Conservation Research Unit (WildCRU), Sabah Forestry Department, and Sabah Parks set out to understand the Bornean ferret-badger’s distribution within Sabah. Between 2021 and 2024, the research team set up 188 camera-trap stations across Sabah’s western highlands and recorded the badgers more than 400 times, discovering a new population in the process. The new population in the Nuluhon-Trusmadi Forest Reserve of Malaysian Borneo, expanded the known range of the species, but photo-traps and habitat modeling showed that Bornean ferret badgers are only found within the greater Sabah’s Kinabalu-Crocker-Trusmadi mountain landscape.  “I grew up in Tambunan and had never seen or even heard of the Bornean ferret badger,” said Mohammad Aliyuddin bin Jaini, field manager of the Bornean Carnivore Programme in a press release. “I decided to place some camera traps around my family’s farm simply to see what wildlife might be there, and I was amazed when a Bornean ferret badger appeared in the photographs. To discover that an Endangered species found only in…This article was originally published on Mongabay

A field experiment in Kenya shows that dung beetles disappear when the African elephants they depend on for their fecal food and shelter also vanish locally. This is the first time that coextinction, the disappearance of one species leading directly to the extinction of another species, has been demonstrated in a large-scale field experiment, according to a recent study. In 2008, the researchers built a set of 10,000-square-meter (2.4 acres) exclosures in Mpala, Kenya. The exclosures were a fenced area of natural savanna habitat that kept out certain animals. Some exclosures kept out elephants, simulating what would happen if elephants went extinct from the landscape. The research focused on the connection between elephants and dung beetles, which bury and consume the feces of larger animals. Dung beetles provide an essential ecosystem service of ensuring feces doesn’t pile up to contaminate the land and water, which reduces the density of biting flies. The beetles also help with nutrient cycling, which keeps the soil and ecosystems thriving.  The researchers set out to see if removing elephant dung would affect the dung beetle community, and if it could lead to coextinction of some dung beetle species. The scientists, led by researcher Finote Gijsman, measured the dung preferences of 179 Kenyan dung beetle species and found that dung beetles love elephant dung. The team used modeling to predict that when elephants became locally extinct within the enclosures, 28% of dung beetle species would go extinct along with them. Their prediction was very close: 23%…This article was originally published on Mongabay

While on a deep-sea expedition in the Galapagos in 2015, scientists found a golf-ball sized, short-armed blue octopus. In a recent study, they confirmed that it’s new to science. The newly described octopus, named Microeledone galapagensis, was first sighted with a remotely operated vehicle (ROV) near an underwater mountain, roughly 1,773 meters (5,800 feet) below the Pacific Ocean surface close to Darwin Island.   Expedition researchers from the Charles Darwin Foundation and the Galápagos National Park Directorate collected it with their ROV. They saw two more octopus individuals on video. The body of the collected specimen was preserved and sent to octopus expert Janet Voight at the Field Museum in Chicago, Illinois, U.S.  Voight and colleagues at the museum scanned the octopus using computed tomography (CT) to create a 3D model of the individual. The researchers then used the CT model to examine its internal organs and mouth parts.    “When you describe a new species of octopus, you have to look at all the parts, including the mouth, the beak, and the teeth. And to see those things, you have to cut the specimen open. We only had the one specimen, so I didn’t want to take it apart,” Voight said in a press release.   A comparison of the blue octopus’ parts with those from other octopus species revealed that it was a new-to-science species. Unlike many octopuses, Microeledone galapagensis is small, squat, and has short, stubby arms with few arm suckers. “One of the interesting questions about…This article was originally published on Mongabay

Starting in 2018, gray whales began regularly stopping in California’s San Francisco Bay, where they are vulnerable to ship strikes in one of the busiest ports in the United States. In response, researchers have deployed a monitoring network of thermal cameras and AI software to alert ships when whales are present in the bay to help them avoid whale collisions.  Gray whales (Eschrichtius robustus) have one of the longest migrations of any mammal species, roughly 19,000 kilometers (12,000 miles) from their feeding grounds in Alaska to their breeding grounds in Mexico, and back again. Climate change is making their feeding grounds in Alaska less productive, leaving the whales hungry as they head south to breed. Scientists believe that’s why gray whales have started stopping in San Francisco Bay to eat along their migration route. But the new pit stop brings whales into busy shipping zones, where more than 20 were killed by ship collisions in 2025, according to a news release. Whale biologists at the Benioff Ocean Science Lab, WhaleSpotter, and the Marine Mammal Center have developed thermal cameras that can detect the heat signature of whale spouts and bodies when the whales surface.  “Next a trained human confirms the detection and will help classify the species when possible,” Rachel Rhodes, a project scientist with the Benioff Ocean Science Lab told Mongabay in an email. Then the information is, “posted publicly on [the] Whale Safe website, which is accessed by mariners in the Bay Area including Vessel Traffic Service and…This article was originally published on Mongabay

Small-scale gold mining is a major cause of deforestation in the Amazon, and researchers found that in Guyana it destroys dung beetle communities and prevents their recovery for decades. Gold mining causes 90% of the deforestation in the Guiana Shield, which contains a quarter of the Amazon rainforest as well as large gold deposits, according to a recent study. Most of the gold mining in this region, including in Guyana, is artisanal, driven by small-scale mining rather than large industrial mines. To understand the long-term “ecological legacy” of such mining, a team of researchers measured dung beetle communities at 16 abandoned small-scale gold mine sites in northwest Guyana. They choose dung beetles, because the insects are easily sampled and play key roles in rainforest functions like nutrient cycling, seed dispersal and pollination. For control, the team monitored dung beetle communities at five nearby intact forests. At every mining site, the researchers sampled dung beetles at three locations: the center of the mine where vegetation was regrowing, at the edge where the mine met the forest, and about 100 meters (328 feet) away into the forest. They trapped dung beetles using human feces as bait.  Study lead author Sean Glynn from the University of Kent, U.K., told Mongabay by email that because they were camping remotely, they didn’t have reliable access to feces from other animals to use as bait, “however, human seems to always be the best.”  The team also recorded air temperature and vegetation structure at each of the…This article was originally published on Mongabay
