Her research utilizes a combination\ \ of laboratory experiments, field data collection, and modeling to quantify\ \ and better understand the food web processes that may pose limitations to\ \ the growth and production of native fishes in a variety of habitats. Current\ \ research projects use these methods to understand the impacts of invasive\ \ fish species to growth and production of native salmonids and evaluate food\ \ web limitations to the feasibility of introducing anadromous salmonids above\ \ high-head dams. Shelley has previously participated in research characterizing\ \ food web impacts following dam removal in the Elwha River, synthesizing science\ \ products and cost estimates for dam removals worldwide for the U.S. Geological\ \ Survey Dam Removal Science Database, and improving our understanding of barotrauma\ \ in fish associated with turbine passage at hydropower dams."
