Most Americans accept genetic engineering of animals if it benefits human health, but other purposes, including efforts to resurrect extinct species, are less welcomed. A recent study by the Pew...

Could genetic advances in the laboratory transform wildlife management on the ground? It’s a question APHIS Wildlife Services biologists are asking as they look at adopting genetic technologies increasingly being used in medicine...

Endangered loggerhead sea turtles (Caretta caretta) make long journeys around the Atlantic Ocean but always return to the same beaches where they hatched to reproduce. But how do they know...

A team of undergraduate students led by their biology professor recently discovered 15 new species of “smiley-faced” spiders throughout North and South America. In a study published in the Zoological...

Certain populations of small, dark flying squirrels that live in cool forests along the Pacific Coast are actually a unique species that had never been classified before, researchers discovered. They...

Where highways have been identified as barriers to seasonal movements of migratory pronghorn, a project just beginning in Wyoming hopes to highlight the genetic effects of these anthropogenic stressors on...

While scientists have agreed for many years that there are as many as 10,000 bird species in the world, recent research shows there might be more species than once thought...

Earth boasts four separate species of giraffe, not one, as scientists formerly believed, according to new research. To untangle the giraffe lineage, researchers analyzed DNA from giraffes across Africa, including...

Tucked away in the National Wildlife Research Center’s (NWRC) genetics laboratory, biologist Dr. Tim Smyser opens a box from USDA Wildlife Services field specialists in Florida. It could have come...
