Western States Cinnamon Teal Initiative

Cinnamon Teal are a relatively understudied and WERC scientists are working with agencies from seven other states collecting data on their ecology which will help inform distribution, movements and habitat use.

Southern California Wildfire Risk Scenario Project

Every year, wildfires devastate the landscapes of Southern California from Los Angeles to San Diego. How has a higher number of human-caused fires affected fire hazards and threats to resources? WERC’s Dr. Jon Keeley and collaborators are analyzing fire patterns across the state to help cities balance their management of fire hazards and natural resources.

Polar Bear Health and Disease Diagnostics

In 2012, scientists noticed that nearly a third of polar bears sampled in a study in Alaska were suffering from hair loss and poor health. Drs. Lizabeth Bowen and A. Keith Miles of WERC used new technology to track down and identify the factors responsible for driving disease in Alaskan polar bears.

Developing Physiological Diagnostics for the Desert Tortoise

The Mojave desert tortoise is listed as “threatened” under the Endangered Species Act and faces threats from habitat loss, predators, and disease. Drs. Lizabeth Bowen and A. Keith Miles with WERC are designing new methods to determine the type and influence of stressors present in the environment for the tortoise and other wildlife.

Invasive Plants and Fire

Fire has had a very different influence on the forests and shrublands of California. Unlike the case in many forests where fires have been excluded for over a century, shrublands throughout the state have experienced the opposite impact. Invasive grasses that burn more readily than native plants have increased the frequency of wildfires in southern California shrublands. As fire clears swathes...

Acoustic Detection of Ashy Storm-Petrels

Together with industry and Federal partners, WERC's Josh Adams and team are using acoustic monitors like the one above to study the range and population size of the Ashy Storm-petrel, an elusive seabird found in the California Coastal National Monument. Their research will inform management and conservation of this species and other seabirds.

Ecology of Infectious Diseases

The public is most familiar with parasites' role in spreading infectious diseases to people and domestic animals. In tropical developing countries, malaria, schistosomiasis, and other infectious diseases cause significant human suffering. While most related studies focus on treating patients, Dr. Kevin Lafferty is studying how ecology of the local environment affects transmission of infectious...

Ecology and Conservation of Reptiles

This project improves our understanding of the ecology of reptiles in California and evaluates methods of managing landscapes and these imperiled species. In particular, Dr. Brian Halstead examines the distribution and demography of reptiles to understand factors that affect where they are found and how populations change. He further explores the relationships of reptiles with their abiotic...

Contaminants in Waterbirds and Effects on Avian Reproduction

California’s Central Valley and San Francisco Bay Estuary have a long history of mercury contamination from past mercury mining and gold extraction. Waterbirds are particularly susceptible to mercury because of their use of wetland habitats where methylmercury (the most toxic and biologically available form) is produced and relatively low methylmercury exposure can reduce reproductive success...

Wetland Restoration in the San Francisco Bay Delta and Pacific Northwest

Estuaries and healthy coastal habitats are among the most productive ecosystems on Earth. They provide a variety of benefits, including habitat and food for fish and wildlife, flood and erosion protection, improved water quality, increased carbon sequestration, as well as beautiful scenery and opportunities for recreation.  Along the U.S. Pacific Coast, both the San Francisco Bay estuary and...

Ecology and Conservation of Desert Bighorn Sheep

Dr. Kathleen Longshore’s goal is to understand how predator/prey relationships, disease and human-caused disturbance work separately and synergistically to impact bighorn sheep populations under variable ecological stress. Information from this project will provide managers with an understanding of specific and regional impacting factors that contribute to impact variation in population trends...
