Research provides new insight into how toothed whales and dolphins evolved to navigate the underwater world using sound waves.
Though wildlife trafficking has been effectively disrupted since the first World Wildlife Day—established 50 years ago today via the 1973 Convention on International Trade in Endangered Species (CITES) of Wild Fauna and Flora—a newly published case study on one of the world’s rarest tortoise species, the ploughshare tortoise, highlights how much room for improvement still exists.
Wolves on an Alaskan island caused a deer population to plumet and switched to primarily eating sea otters in just a few years, a finding scientists at Oregon State University and the Alaska Department of Fish and Game believe is the first case of sea otters becoming the primary food source for a land-based predator.
A study by researchers from the University of Adelaide and other institutions has found that in a population of island tiger snakes the bones in their jaws increase in length after feeding on large prey, while their mainland counterparts show no change.
The number of fish species recorded in Madidi National Park and Natural Integrated Management Area (PNANMI), Bolivia has doubled to a staggering 333 species – with as many as 35 species new to science – according of a study conducted as part of the Identidad Madidi expedition led by the Wildlife Conservation Society.
Marking trees are important hotspots of communication for cheetahs: Here they exchange information with and about other cheetahs via scent marks, urine and scats.
Bats use distinct structures in the larynx to produce high-frequency echolocation calls and lower-frequency social calls, according to a study.
Today, the U.S. Fish and Wildlife Service (USFWS) announced that emperor penguins have been listed as a threatened species under the Endangered Species Act (ESA) based on evidence that the animal's sea ice habitat is shrinking and is likely to continue to do so over the next several decades. This listing comes more than one year after a USFWS proposal to list the species, and confirms that the animal is at risk of becoming an endangered species--in danger of extinction--in the foreseeable future if its habitat continues to be destroyed or adversely changed.
Project FeederWatch is back—with more ways to participate, more time to participate, and more ways to keep track of who is seeing what, where. The expanded 36th season of FeederWatch begins November 1 and ends April 30, 2023.
Researchers have used the mathematical equations of chaos theory to analyse the data from long-term monitoring of an electronically tagged narwhal.
When it comes to showing affection towards people, many dogs are naturals. Now comes word reported in the journal Ecology and Evolution on September 20th that the remarkable ability to show attachment behaviour toward human caregivers also exists in wolves.
Despite the high number, first global assessment shows illegal exploitation slightly declining.
Jiuzhaigou National Nature Reserve, a World Heritage Site, lies in the transition zone from the eastern edge of the Qinghai-Tibet Plateau to the Sichuan Basin in Sichuan Province, China, and occupies an area of 651 km2.
Scientists have been warning for quite some time that monarch butterflies were headed for extinction. But to misquote Mark Twain, rumors of their demise were greatly exaggerated. A new study found that growth in the summer population has compensated for losses during the winter.
Princeton geneticist Stephen Gaughran recently confirmed that 'Fernanda' comes from the same species as a tortoise collected from Fernandina Island more than a century ago, and those two are genetically distinct from all other Galápagos tortoises.
New research published in the June 3, 2022 journal Science reveals that 44 percent of Earth’s land area – some 64 million square kilometers (24.7 million square miles) requires conservation to safeguard biodiversity.
A brand-new endangered California Condor chick hatched on May 14, and viewers can watch live as the little one grows up to become a majestic denizen of the skies.
For most sea turtles, the journey to find the ocean from their nests is pretty straightforward. However, leatherback hatchlings more often crawl around in circles trying to find the ocean. Circling delays their entry into the ocean, wastes energy, and places them at greater danger from natural predators. Under different moon phases: bright light during full moon and only starlight under new moon, researchers have a better understanding of why this circling behavior happens and why it is most commonly observed in leatherbacks.
A new study has found contaminants that were banned decades ago are still imperiling critically endangered California condors.
Flying reptiles could change the colour of their feathers, research finds.
FishSounds.net is the first online, interactive library for the sounds fish make when communicating or interacting with their environment. Fish sounds provide scientists valuable data for studying and conserving underwater ecosystems. An accompanying review study found that just under a 1,000 fish make sounds for communication, though this is likely an underestimate.
One population of female common yellowthroats prefers males with larger black masks, but another group of females favors a larger yellow bib. A new study has found that both kinds of ornaments are linked to superior genes.
A new scientific study shows that all previously proposed body forms of the gigantic Megalodon, or megatooth shark, which lived nearly worldwide roughly 15-3.6 million years ago, remain in the realm of speculations.
Wild animals often return to the same places to eat, travel and raise their young. A team found that, while this “consistent” behavior may be beneficial when environmental conditions don’t change very fast, those benefits may not hold up in an ever-changing world dominated by humans.
New research shows that humans had a significant role in the extinction of woolly mammoths in Eurasia, occurring thousands of years later than previously thought.
A new study in the journal Biological Conservation has documented Nigeria’s staggering role in trafficking of wild pangolins, the anteater-like mammal whose scales are used in traditional Chinese medicines; all international commercial trade in pangolins and their parts is illegal.
While many animals have adapted to live with wildfires of the past — which were smaller, more frequent and kept ecosystems in balance across the West — it’s unclear to scientists how animals are coping with today’s unprecedented megafires. A team of researchers tracked a population of black-tailed deer before, during and after the 2018 Mendocino Complex Fire and found that most of the deer returned home within hours of the fire, while trees were still smoldering.
Leprosy has been found in wild chimpanzees for the first time, a new study reveals.
Mahahual is a small fishing village in the Mexican Caribbean that receives a large number of tourists every year.
Tagging reveals that closely bonded female bats leave the roost separately but reunite when hunting.
A new study finds that that some large whale species (humpback, fin and minke whales) use the waters off New York and New Jersey as a supplemental feeding area feasting on two different types of prey species.
Roads have a negative impact on chimpanzee populations that can extend for more than 17 km, new research shows.
Trickling down over rocks, surrounded by wildflowers and ferns, Appalachian mountain streams are chock-full of life.
A predator doesn’t need to have the quickest speed or reflexes to catch a bird. In a paper publishing August 23 in the journal Current Biology, researchers report the first documented evidence of a tortoise going in for the kill: biting the head of, killing, and eating a tern chick.
A team of scientists has discovered a new marmoset species in the Brazilian Amazon.
Scientists at the University of Bristol have discovered evidence that giraffes are a highly socially complex species.
Climate change is further exacerbating human-wildlife conflicts by straining ecosystems and altering behaviors, both of which can deepen the contacts — and potential competition — between people and animals.
A new study led by WCS-India documents how a big cat deity worshipped by Indigenous Peoples facilitates coexistence between humans and leopards.
Elephants and their forebears were pushed into wipeout by waves of extreme global environmental change, rather than overhunting by early humans, according to new research.
Animal rights advocates and hunters may have more in common than they think when it comes to nature conservancy, according to a newly published study by a Texas A&M AgriLife researcher.
Each year, many shark species migrate hundreds of miles, traversing ocean waters to return to the same spot year after year. Now, Florida State University researchers have found that sharks likely use the Earth’s magnetic fields to help guide them on these long-distance journeys.
Bats' "supersense" of time
A new study revealed that a drastic reduction of deaths of one of Africa’s rarest primates, the Zanzibar red colobus (Piliocolobus kirkii), followed the installation of four speedbumps along a stretch of road where the species frequently crossed.
Eagle and waterfowl deaths occur in late fall and winter within reservoirs with excess invasive aquatic weeds, and birds can die within five days after arrival.
A team of scientists have identified a wide swath of habitat in Arizona and New Mexico that they say could eventually support more than 150 jaguars.
Mexican wolves in the American Southwest disappeared more quickly during periods of relaxed legal protections, almost certainly succumbing to poaching, according to new research published Wednesday.
Scientists have designed and built an on-demand video device for white-faced saki monkeys to activate as and when they like. It's up to the animals to decide whether they want to step inside the device – the equivalent of pressing play – to watch the video of the week, from sealife like fish and jellyfish to wiggly worms and other zoo animals to abstract art and lush forests.
A team of marine scientists has confirmed that southern Africa’s most threatened endemic shark – the Critically Endangered shorttail nurse shark (Pseudoginglymostoma brevicaudatum) – has been found to occur in Mozambique; a finding that represents a range extension of more than 2,000 kilometers (1,242 miles).
WCS Argentina recently delivered a new litter of specially trained livestock guardian dogs that work directly with herders to reduce conflict with pumas (Puma concolor) and other native carnivores living on the Patagonian steppe.
Fish populations tend to do better in places where rigorous fisheries management practices are used, and the more measures employed, the better for fish populations and food production, according to a new paper published Jan. 11 in Nature Sustainability.
