Master’s Research

202Didymosphenia geminata (Didymo) is a nuisance algae that can cover entire streambeds under certain environmental conditions. While relatively easy to treat, it is unknown whether Didymo decreases the amount of invertebrate prey for fishes. In the Kootenai River basin of Montana and British Columbia, I am working to determine if Didymo is altering stream invertebrate assemblages and how any changes maybe impacting native fishes such as Bull Trout and Redband Trout. I am also using this data to help refine energy-flow food webs as a tool for use in conservation research.

Additionally, with partners at Montana State University, I am helping test an emerging technology called a fatmeter for in-field assessment of individual fish condition.
