The scientists from the Forest and Rangeland Ecosystem Science Center capitalize on their diverse
expertise to answer critically important scientific questions shaped by the equally diverse environments
of the western United States. FRESC scientists collaborate with each other and with partners to provide
rigorous, objective, and timely information and guidance for the management and
conservation of biological systems in the West and worldwide.

Understanding Species Persistence at Distributional Edges
Species living in marginal habitats at the edges of larger populations can be genetically different and are often more vulnerable to climate changes, habitat...
Temperature-related Effects of Dam Operations on Western Pond Turtles
Western pond turtles are ectotherms – their body temperature is controlled by their environment. To study how altered stream temperatures resulting from dams influence...
2011 International Piping Plover Census Report
The piping plover is one of the most imperiled shorebirds in the United States and Canada. Every five years since 1991, the USGS coordinates an International Piping...
Using Ultrasonic Acoustic Deterrents to Reduce Bat Fatalities
Changing wind turbine operations during periods of high risk of bat collisions has been shown to reduce bat fatalities, yet operational minimization may be...
Surveying Fish and Aquatic Invasive Species in Restored Meadows
In the Plumas National Forest in northern California, meadow restoration projects have been completed over the past 18 years to elevate water levels, retain flow, and...
Range-wide Habitat and Population Connectivity in Greater Sage-grouse
State agencies within the range of the greater sage-grouse have developed Priority Areas for Conservation, or PACs, and conservation plans to manage and mitigate the...
provides expertise in contaminant accumulation and transfer in food webs, contaminant cycling, mercury toxicity, and lake and wetland ecology. Collin broadly applies his research to all animal species, especially waterbirds and fish. He also directs FRESC's Contaminant Ecology Laboratory, which maintains facilities for measuring mercury and other trace metals in environmental media, as well as endocrine disruption and biomarker responses in various fish and avian species.
Measuring the Ecological Effects of Contaminants
focuses on determining what happens to natural systems when they are exposed to contaminants at environmentally relevant concentrations. Our research is specifically designed to measure the effects of contaminants on biological functioning across a gradient of ecological scales. Perhaps the most important component of this theme is the overarching goal of integrating the effects at all levels of organization to form a more cohesive understanding of the emergent responses to contaminant exposure.
