As wildlife biologists help return California condors to the wild, researchers found the recovering population has surprisingly high genetic diversity, which offers some good news for a species that has been difficult to restore. California …
In the 17th and 18th century, North American plains bison (Bison bison bison) nearly went extinct due to unregulated and unsustainable harvest and habitat loss. Across the country today, some 30,000 bison are conserved by …
Kentucky may have discovered the recipe for success when it set out to reintroduce elk to the state about 20 years ago, researchers found. The state brought in a large number of animals from herds …
Humans’ presence on the landscape affects different species differently. For some species and population, genetic diversity decreases alongside human land use and population density. For others, it can increase, according to recent research. “Our intuition …
California is building what state transportation officials will be the world’s largest wildlife overpass. Paid mostly with private donations, the overpass will span 200 feet across 10 lanes of U.S. 101 about 35 miles northwest …
Habitat fragmentation is splintering California’s mountain lion (Puma concolor) populations, researchers found. As urbanization between Los Angeles and San Diego spreads across landscapes historically used by mountain lions, it is causing some groups of mountain …
Some 1.4 million white-tailed deer (Odocoileus virginianus) roam in Missouri today, but less than a century ago, their numbers had dwindled to the verge of extirpation. It would be understandable, then, if today’s deer showed …
Eastern massasauga rattlesnakes (Sistrurus catenatus) are declining throughout most of their range, but in Illinois, a 10-year genetics study found a lack of inbreeding among the rattlers there, offering hope for the threatened snake’s recovery. …
Despite modest increases in the threatened southern sea otter population (Enhydra lutris nereis), their genetic diversity has remained the same, prompting researchers to question the future of their recovery. The southern sea otter population consists …
When Japanese bush-warblers (Cettia diphone) were introduced to Oahu in the 1920s, it might not have been good for native wildlife, but it turned out to be helpful for researchers. As the birds made their …
