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.

Ecological thresholds and transformations due to climate change: The role of abiotic stress
An ecological threshold is the point at which a comparatively small environmental change triggers an abrupt and disproportionately large ecological response. In the face of accelerating climate change, there is concern that abrupt ecosystem transformations will become more widespread as critical ecological thresholds are crossed. There has been ongoing debate, however, regarding the...

Biodiversity surveys of Wake Atoll—Featuring field guides for plants, arthropods, and herpetofauna
IntroductionThe U.S. Air Force (USAF) issued funds to the U.S. Geological Survey (USGS) to update the biosecurity plan, create a current (2019) flora and fauna species identification index, and do container evaluations for the presence of potential invasives. The current (2019) biosecurity protocols used for prevention were evaluated, and new biodiversity surveys were completed for...
Climate and dispersal ability limit future habitats for Gila monsters in the Mojave Desert
Describing future habitat for sensitive species can be helpful in planning conservation efforts to ensure species persistence under new climatic conditions. The Gila monster (Heloderma suspectum) is an iconic lizard of the southwestern United States. The northernmost range of Gila monsters is the Mojave Desert, an area experiencing rapid human population growth and urban sprawl. To...

Waterbird Ecology and Movement in the Saline Lakes
How do changing conditions in the terminal lakes of the Great Basin effect the migratory birds that depend on them? USGS scientists investigate bird movement and habitat use to find out.
Assessing heat stress in migrating Yukon River Chinook Salmon
We will examine evidence of heat stress in Yukon River Chinook salmon ( Oncorhynchus tshawytscha) using heat shock proteins and gene expression.
Prey Availability
Migratory wildlife need to balance the benefits of migration and reproduction with the physiological costs. This is particularly challenging in dynamic environments like wetlands, where food levels can vary greatly from year to year. For shorebirds in the Great Basin region, saline or terminal lakes provide essential habitats during their annual life cycle. To understand how changes in hydrology...
