Despite their name, black bears don’t always have black coats. That can make it difficult to tell a brown-colored black bear (Ursus americanus) from a grizzly (Ursus arctos horribilis). Researchers...

Researchers are collaborating to sequence genomes for as many bee species in the United States as they can, including many that are facing declines. The project, dubbed Beenome100, will be...

To understand how Arctic species might respond to climate change, researchers dug into how cold-adapted species responded between previous ice ages. Biologists had concluded that as massive ice sheets retreated,...

Researchers have begun to sequence the genes of rabies viruses detected in New England bats using a technique they say can provide important information about how rabies spreads and t...

Biologists with the Oregon Department of Fish and Wildlife are working to conserve fishers (Pekania pennanti), a species state listed as sensitive. Fishers are hard to find in the wild,...

Surveying and monitoring endangered lizards can be difficult. The species tend to be cryptic. Permits are hard to come by. And biologists often try to avoid disturbing the lizards while...

Genetic information has led researchers to determine that there are more unique species of spotted skunks than previously thought. Biologists haven’t completely agreed on the number of spotted skunks for...

In bear country, it’s not uncommon to notice the evidence of a bear rubbing against a tree, even if you don’t catch it in the act. Claw marks may be...

A new test using just a drop of blood can tell research how much exposure bats have had to pesticides. “We know very little about the effects of pesticides, and...

Over the past century, a growing human population has caused movement barriers for lion populations, reducing their genetic diversity. “The African landscape has changed drastically over the past century with...
