Western Ecological Research Center (WERC)
The Western Ecological Research Center (WERC) is a USGS Ecosystems Mission Area operation serving primarily California and Nevada. WERC scientists work closely with Federal, State, academic, and other collaborators to address a diverse array of high-profile topics. Topics include research on effects of wildfire, sea level rise, drought, energy development and more on federal Trust species.
As wildlife diseases increase globally, an understanding of host-pathogen relationships can elucidate avenues for management and improve conservation efficacy. Amphibians are among the most threatened groups of wildlife, and disease is a major factor in global amphibian declines.
Amphibian species and community richness has been declining in North America and climate change may play a role in these declines. Global climate change has led to a range shift of many wildlife species and thus understanding how these changes in species distribution can be used to predict amphibian community responses that may improve conservation efforts.
There’s hot new real estate for wildlife in south San Francisco Bay, and a report from USGS biologists shows that the waterbirds are flocking in.
Wildlife underpass use and environmental impact assessment: A southern California case study
Environmental planners often rely on transportation structures (i.e., underpasses, bridges) to provide connectivity for animals across developed landscapes. Environmental assessments of predicted environmental impacts from proposed developments often rely on literature reviews or other indirect measures to establish the importance of wildlife...Longcore, Travis; Almaleh, Lindsay; Chetty, Brittany; Francis, Kathryn; Freidin, Robert; Huang, Ching-Sheng; Pickett, Brooke; Schreck, Diane; Scruggs, Brooke; Shulman, Elise; Swauger, Alissa; Tashnek, Alison; Wright, Michael; Boydston, Erin E.
Canid vs. canid: Insights into coyote–dog encounters from social media
While the relationship between coyotes (Canis latrans) and house cats (Felis catus) may be characterized as one between predators and their prey, coyote interactions with domestic dogs (C. lupus familiaris) appear to be more varied and may include behaviors associated with canid sociality. While encounters between coyotes and dogs are difficult to...Boydston, Erin E.; Abelson, Eric S.; Kazanjian, Ari; Blumstein, Daniel T.
An integrated population model for greater Sage-Grouse (Centrocercus urophasianus) in the bi-state distinct population segment, California and Nevada, 2003–17
The Bi-State Distinct Population Segment (DPS) of greater sage-grouse (Centrocercus urophasianus, hereinafter “sage-grouse”) occupies parts of Alpine, Mono, and Inyo Counties in California, and parts of Douglas, Esmeralda, Lyon, Carson City, and Mineral Counties in Nevada and was proposed for listing as threatened under the Endangered Species Act...Mathews, Steven R.; Coates, Peter S.; Prochazka, Brian G.; Ricca, Mark A.; Meyerpeter, Mary B.; Espinosa, Shawn P.; Lisius, Sherri; Gardner, Scott C.; Delehanty, David J.
