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.

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.
From tongue rolling alpacas to irritable yaks and perturbed pigs, new research has lifted the lid on why some farm and zoo animals cope well with captivity and others display signs of stress. Researchers from Aberystwyth and Portsmouth universities in the UK have published the first large-scale study to identify which species of hoofed animals, known as ungulates, are better suited to captive environments and which require better husbandry if kept in captivity.
A group of scientists led by Alejandro Arteaga, grantee of The Explorers Club Discovery Expeditions and researcher at Khamai Foundation, discovered three new cryptozoic (living underground) snakes hidden under graveyards and churches in remote towns in the Andes of Ecuador. The discovery was made official in a study published in the journal ZooKeys.
A new study led by scientists at Woods Hole Oceanographic Institution (WHOI) and University of Washington Applied Physics Laboratory (UW APL) finds that marine predators, such as tunas, billfishes and sharks, aggregate in anticyclonic, clockwise-rotating ocean eddies (mobile, coherent bodies of water). As these anticyclonic eddies move throughout the open ocean, the study suggests that the predators are also moving with them, foraging on the high deep-ocean biomass contained within.
Scientists at the Woods Hole Oceanographic Institution (WHOI) and European research institutions are calling for better protections for juvenile emperor penguins, as the U.S. Fish and Wildlife Service considers listing the species under the Endangered Species Act and the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) considers expanding the network of Marine Protected Areas (MPAs) in the Southern Ocean.
While motivations change with socio-economic context, hunting intensity is more constant.
With the help of an acoustic camera that visualizes sound pressure, researchers from the University of Vienna investigated the calls of Asian elephants. The elephants emitted their low frequency “rumbles” mainly through their trunk or through their mouth and trunk simultaneously, and only seldomly through their mouth alone. This is the first study to conclusively demonstrate the combined oral and nasal call emission in a non-human animal. The study has recently been published in the journal “Animals”.
As the effects of climate change mount, ecosystem restoration in the US West has garnered significant public attention, bolstered by President Joe Biden's America the Beautiful plan to conserve 30% of US land and water by 2030. Writing in BioScience, William J. Ripple and 19 colleagues follow up on the Biden plan with a proposal for a "Western Rewilding Network," comprising 11 large reserve areas already owned by the federal government.
From cattle to uncontrolled wildlife, pesky but pervasive large parasites like tapeworms have a far greater impact on the total body health of their mammal hosts than previously known, new University of Alberta research suggests.
Three new species of black-bellied salamander have been discovered by a research team led by R. Alexander Pyron, the Robert F. Griggs Associate Professor of Biology at the George Washington University. The new salamanders, which are found in the southern Appalachian Mountains of the eastern United States, stem from black-bellied populations that were long considered to be a single species.
A pair of Orca (Killer Whales) that have been terrorizing and killing Great White Sharks off the coast of South Africa since 2017 has managed to drive large numbers of the sharks from their natural aggregation site.
June 16 is World Sea Turtle Day, an occasion to consider the role these creatures play in the marine ecosystem. Florida State University Associate Professor Mariana Fuentes researches sea turtles and looks for ways to help turtles and humans coexist. She answered five questions about her work and how science can help inform public policy.
A new study by the University of Georgia found Florida panthers are the No. 1 cause of mortality for white-tailed deer in Southwest Florida.
From embryo to turtle cracker: a team led by palaeobiologist Julia Türtscher from the University of Vienna studied the multiple changes in tooth shape in the tiger shark. The study, recently published in the Journal of Anatomy, is also central in drawing conclusions about extinct species from the myriad of preserved shark teeth in the field of palaeontology.
There’s a brand-new series of seven field guides to help people learn about the birds found in their region of the United States and Canada.

How do climate change and human-elephant conflict affect household food security in Africa? NAU wildlife conservationist Duan Biggs spent three years with an international team of researchers investigating the dynamics between wildlife, people and the environment on the African savannah to better understand how both climate change and human-elephant conflict can impact household food insecurity in the region.
A team of scientists have identified coronaviruses closely related to SARS-CoV-2 from two bats sampled in Cambodia more than a decade ago.
Dwarf mongooses remember which groupmates have picked fights with others during the day and later shun the aggressors during pre-bedtime socialising sessions, according to new research.
A new study from WCS and multiple partners that modeled changes in the world’s 45 different “life zones” from climate change revealed that climate impacts may soon triple over these areas if the earth continues “business-as-usual” emissions.
The high-contrast pattern of giant pandas helps them blend in with their natural environment.
The first-ever Africa-wide assessment of great apes – gorillas, bonobos and chimpanzees – finds that human factors, including roads, population density and GDP, determine abundance more than ecological factors such as forest cover.
Seabirds from Gough Island in the south Atlantic, Marion Island near Antarctica and the coasts of both Hawaii and Western Australia have a dangerous habit: eating plastic.
A research team led by the University of Minnesota Twin Cities has completed a first-ever global population estimate of Weddell seals in Antarctica, showing that there are significantly fewer seals than previously thought. Documenting the seals’ population trends over time will help scientists better understand the effects of climate change and commercial fishing.
