Area of Expertise:
Dr. Rana El-Sabaawi is an Assistant Professor and heads the El-Sabaawi Lab at the Univerity of Victoria. She studies the effects of nutrition on ecosystem processes, with a particular interest in how nutrition changes in the course of trait evolution. Applying biological stoichiometry to well-studied evolutionary models such as guppies and sticklebacks allows her to characterize nutritional constraints that might arise during evolutionary processes, and also how changes in phenotype distributions affect ecosystems. She is also interested in how nutrition affects the response of organisms to large-scale changes like urbanization, predator loss, or species invasion.
Dr. El-Sabaawi’s research group studies the interactions between animals and their environment, especially in the context of landuse change. They use a variety of approaches from ecology, evolution, nutritional physiology, and biogeochemistry.
Rana and her research team are also investigating the effects of urban development on salmon streams in the Greater Victoria area, conducting field surveys and experiments to try and repopulate some of the streams.
