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.

Sampling across 20 years (1996–2017) reveals loss of diversity and genetic connectivity in the Coachella Valley fringe-toed lizard (Uma inornata)

The Coachella Valley fringe-toed lizard (Uma inornata) is a federally threatened, aeolian sand dune obligate, endemic to the Coachella Valley, California. Historically, U. inornata is thought to have formed a large interconnected metapopulation across the valley, with local dune habitat and population size fluctuations linked to...

Physiological and gene transcription assays to assess responses of mussels to environmental changes

Coastal regions worldwide face increasing management concerns due to natural and anthropogenic forces that have the potential to significantly degrade nearshore marine resources. The goal of our study was to develop and test a monitoring strategy for nearshore marine ecosystems in remote areas that are not readily accessible for sampling. Mussel...

Designing multi-scale hierarchical monitoring frameworks for wildlife to support management: A sage-grouse case study

Population monitoring is integral to the conservation and management of wildlife; yet, analyses of population demographic data rarely consider processes occurring across spatial scales, potentially limiting the effectiveness of adaptive management. Therefore, we developed a method to identify hierarchical levels of organization (i.e., populations...
