Didymosphenia 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 worked to determine if Didymo alters stream invertebrate assemblages and see if any changes were impacting native fishes such as Bull Trout, Redband Trout, and Slimy Sculpin. I am also using this data to help refine energy-flow food webs as a tool for use in conservation research.

Beavers & Bull Trout in the Bitterroot

Pre-spawn adult Bull Trout

A long history of cattle grazing, channel straightening, and beaver trapping has left many streams in western North America degraded and down-cut. With partners at Utah State University and the Bitter Root Water Forum, I am working to A) restore down-cut streams in the East Fork Bitterroot River drainage using process-based restoration techniques and B) determine if the popular beaver dam analogue (BDA) structure is passable by threatened Bull Trout.
