Jeff Wesner
Assistant Professor
Biology, College of Arts & Sciences
UCL Churchill-Haines Labs 170F
Phone: 605-677-6178
Teaching Interests:
Ecology, Fish Ecology, Stream Ecology
Research Interests:
I study the ecology and conservation of stream and terrestrial ecosystems. I use 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 within and across ecological boundaries.
