Wolves on an Alaskan island caused a deer population to plummet 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.
The western bumble bee was once common in western North America, but increasing temperatures, drought, and pesticide use have contributed to a 57% decline in the occurrence of this species in its historical range, according to a new U.S. Geological Survey-led study.
The Center for Biological Diversity submitted a petition this week asking the U.S. Fish and Wildlife Service to reintroduce sea otters to a large stretch of the West Coast. Threatened southern sea otters occupy only 13% of their historic range, and a small population of the animals currently lives on California’s central coast.
The U.S. Fish and Wildlife Service this week announced the completion and publication of the final recovery plan for the Meltwater Lednian stonefly and Western Glacier stonefly.
A chemical used in the production of toilet paper and 'forever chemicals' have been found in the bodies of orcas in British Columbia, including the endangered southern resident killer whales.
National parks are the backbone of conservation. Yet mounting evidence shows that many parks are too small to sustain long-term viable populations and maintain essential, large-scale ecological processes, such as large mammal migrations and natural disturbance regimes.
Twelve scientists are urging the Department of the Interior and the U.S. Fish and Wildlife Service to promptly protect the Pacific walrus under the Endangered Species Act. The Center for Biological Diversity first submitted a petition to list the Pacific walrus as threatened or endangered in 2008, more than a decade ago.
The U.S. Fish and Wildlife Service, after completing its review of a petition to list a Columbia/Snake river basin snail under the Endangered Species Act, found that listing the Columbia Oregonian is not warranted at this time.
The Center for Biological Diversity has filed a lawsuit today challenging what it says is the “failure of the U.S. Fish and Wildlife Service to develop a national gray wolf recovery plan under the Endangered Species Act.”
