In a first-of-its-kind study, researchers at the Georgia Institute of Technology discovered that sea cucumbers — sediment-eating organisms that function like autonomous vacuum cleaners of the ocean floor — play an enormous role in protecting coral from disease. The problem is, they've been overharvested for more than 100 years, and they're now rare.
A new study reveals how soil erosion caused by sika deer foraging reduces the growth of the beech trees.
When a sabertooth tiger called out, what noise did it make – a mighty roar or a throaty purr? A new study from North Carolina State University examined the data behind the arguments for each vocalization and found that the answer was more nuanced than they thought – and that it could depend on the shape of a few small bones.
Pronounced vocal and behavioral changes caused. by wildfire smoke make it possible to assess the health of wild orangutan populations by monitoring the frequency and quality of their sounds.
In Washington state, the presence of two apex predators — wolves and cougars — drives two mesopredator species — bobcats and coyotes — into areas with higher levels of human activity, with deadly results for the mesopredators.
A new WCS-led study that analyzed 17 years of migratory bird-nesting data in Prudhoe Bay, Alaska, revealed that nest survival decreased significantly near high-use oil and gas infrastructure and its related noise, dust, traffic, air pollution, and other disturbances.
Since the 1950s, humanity has produced an estimated 8.3bn tons of plastic, adding a further 380m tons to this amount each year. Only 9% of this gets recycled.
In the Pacific Northwest and British Columbia, southern resident orcas have experienced no net population growth since the 1970s. But northern resident orcas, with a similar diet and territory, have grown steadily. A new study may help explain why: The two populations differ in how they hunt for salmon, their primary and preferred food source.
In a new study, researchers used new technologies to remotely document, for the first time in the wild, the location and timing of shark birth. Named the Birth-Alert-Tag (BAT), this new satellite tag remained inside the uterus, along with the developing shark pups, until the mother shark gave birth and expelled the newborn pups, along with the BAT, into the surrounding water. The BAT then floated to the surface and transmitted to satellites the location of where the shark birth took place. The first of its kind, the BATs were successfully deployed in a tiger shark and scalloped hammerhead shark, documenting the location birth.
Researchers at the University of Bristol have found why zebra fur is thinly striped and sharply outlined.
Thanks to researchers at NSU’s Guy Harvey Research Institute (GHRI) who designed a novel electronic tag package incorporating high-tech sensors and a video camera, we now have for the first time, a detailed view of exactly how sailfish behave and hunt once they are on their own and out of view of the surface.
Findings from a new paper published in Cat News have identified the first ever report of Pallas’s cat on Mount Everest, in the Sagarmatha National Park in Nepal.
It is a popular takeaway choice at fish and chip shops, but new research has revealed threatened species of shark are being sold as flake at some outlets across South Australia. The University of Adelaide study is the first of its kind to examine flake fillets sold at South Australian fish and chip shops.
Scientists have sequenced the genomes of Critically Endangered great hammerhead and Endangered shortfin mako sharks for the first time.
Female rhesus macaques “actively reduce” their social networks and prioritise friends and family as they get older, new research shows.
By scrutinising over a century’s worth of photos, University of Cambridge researchers have made the first ever measurements that show rhinoceros horns have gradually decreased in size over time.
New research, offering the most comprehensive analysis of Asian elephant movement and habitat preference to date, finds that elephants prefer habitats on the periphery of protected areas, rather than the areas themselves.
International trade in animals not regulated by multilateral agreements is putting them under increasing threat. More than three times the number of unregulated animal species are being imported into the United States compared to the number of regulated species. Closer monitoring of trade in these species is urgently required so that they may be protected.
A new scientific review article led by WCS captures the unique and dynamic characteristics of coastal lagoon ecosystems in the Arctic Beringia Region, and discusses how climate change effects and human development could alter these habitats.
Researchers in New York City (NYC) have analyzed the DNA of urban coyotes and discovered that the coyotes eat a variety of native prey species and supplemented with human-sourced food items.
