Annika Walters, PhD
Assistant Unit Leader - Wyoming Cooperative Fish and Wildlife Research Unit
Annika joined the Wyoming Unit as Assistant Unit Leader of Fisheries in 2011. Her research addresses basic questions in population and community ecology and applied questions in conservation biology and fisheries management. Her focus is aquatic ecosystems and how these ecosystems are altered by natural and anthropogenic disturbance. Major research themes include multiple stressors, fish movement patterns, and native fish conservation. Most of her research is motivated by conservation concerns and has implications for management and restoration efforts. She works closely with agency cooperators across Wyoming and the region to address questions that can help inform the management of fishes and aquatic ecosystems. She currently teaches advanced fisheries management and seminars on topics of interest at University of Wyoming.
Annika received graduate degrees from Yale University and was a post-doctoral researcher at the Northwest Fisheries Science Center and at the University of Washington in Seattle.

Science and Products
U.S. Geological Survey science for the Wyoming Landscape Conservation Initiative—2016 annual report
Quantifying 87Sr/86Sr temporal stability and spatial heterogeneity for use in tracking fish movement
The effectiveness of surrogate taxa to conserve freshwater biodiversity
Comparison of burbot populations across adjacent native and introduced ranges
Evaluating early-warning indicators of critical transitions in natural aquatic ecosystems
U.S. Geological Survey science for the Wyoming Landscape Conservation Initiative—2015 annual report
Population connectivity and genetic structure of burbot (Lota lota) populations in the Wind River Basin, Wyoming
Fish assemblage shifts in the Powder River of Wyoming: an unregulated prairie river system previously considered to be relatively pristine.
Density of river otters (Lontra canadensis) in relation to energy development in the Green River Basin, Wyoming
Landscape-scale determinants of native and nonnative Great Plains fish distributions
Stream vulnerability to widespread and emergent stressors: a focus on unconventional oil and gas
Multiple stressors threaten stream physical and biological quality, including elevated nutrients and other contaminants, riparian and in-stream habitat degradation and altered natural flow regime. Unconventional oil and gas (UOG) development is one emerging stressor that spans the U.S. UOG development could alter stream sedimentation, riparian extent and composition, in-stream flow, and water qual
