This iconic herbivore of the arid grasslands and the Andes Mountains in the Southern Cone, depends on vast and connected habitats to feed, reproduce, and rest.
The soprano pipistrelle (Pipistrellus pygmaeus) weighs only a few grams, but it is estimated that members of this small bat species cover thousands of kilometres every year on their nocturnal migrations from north-eastern to south-western Europe.
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.
