Dr Jeff Wesner | Principal Investigator

Jeff works on the ecology and conservation of stream and terrestrial ecosystems. He employs population, community, behavioral and food web ecology to: (1) guide conservation of freshwater species; and, (2) understand how species loss, species introductions and pollution affect food webs.

Graduate Students

Ryan Dunbeck | Masters candidate

Ryan completed his BS in Fish and Wildlife Sciences at the University of Idaho and joined our lab in fall 2019. He is studying the impacts of Asian Carp on freshwater food webs using historical data and experimental approaches.

Tanner Carlson | Masters candidate


Dr Justin Pomeranz

Justin joined the lab in June 2019. He is a food web ecologist who works on size and stage-structured food webs. For his postdoc project, he is using experimental and modeling techniques to understand stage-structured predator-prey interactions in freshwater food webs, and their implications for species coexistence and ecosystem functioning.
