Sarah Peterson
Dr. Sarah Peterson is a Wildlife Biologist at the Dixon Field Station.
She is broadly interested in the ecology and movement of upper trophic level predators, with a focus on birds and mammals. Additionally, she is interested in the interplay between foraging ecology and both contaminant bioaccumulation and toxicological risk. She conducted her PhD at UC Santa Cruz, where she examined how ecology and physiology influence contaminant bioaccumulation (mercury and persistent organic pollutants) in seals and sea lions.
Currently, she works as part of a large collaborative research effort to study ground-nesting waterfowl at the Grizzly Island Wildlife Area. She leads a portion of the study that quantifies survival and movement of ducklings, using VHF radio-telemetry. She also quantifies the space use and movements of raccoons and skunks around duck nests using GPS technology.

Scientists from the USGS Western Ecological Research Center are studying the movements of skunks and raccoons within Suisun Marsh, CA to understand how they navigate the marsh to reach waterfowl nests. Results will inform the management of waterfowl populations within the Central Valley, CA.
