Fishers are not the easiest mammals to keep tabs on. But in Northern California, the Hoopa Valley Tribe’s wildlife division has been capturing and studying them since 2005, creating one of the longest-running datasets of …
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, but checking DNA trap sites …
Human food comprises up to half the diet of carnivores living close to people, researchers found, which can have consequences for the individuals and the ecosystem. “A lot of us have pursued this line of …
The U.S. Fish and Wildlife Service has added a distinct population of fishers (Pekania pennanti) in the southern Sierra Nevada Mountains of California to the list of endangered species under the Endangered Species Act. The …
The Beaver Hills Biosphere in central Alberta includes a patchwork of protected areas, but some of the terrain that fishers in the region rely on most are unprotected. “We really wanted to understand how the …
Biologists surveying carnivore populations in snow-covered regions often have a hard time differentiating between the tracks of similar species. By analyzing track characteristics and snow measurements, a recent study focused on fishers (Pekania pennanti) and …
Fishers haven’t always been prevalent in the central and western parts of New York State. In fact, in the late 1800s and early 1900s, populations declined rapidly due to unregulated trapping and forest fragmentation. But …
Biologists are now closer to understanding fisher (Pekania pennanti) survival and mortality rates following a multiyear study. New research published in the April issue of The Journal of Wildlife Management, found that fishers in California’s Sierra …
