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.
