Teaching:
Stream Ecology (AEcl 418/518) - This dual-listed course explores the biological, chemical, physical, and geological processes shaping the structure and function of flowing water ecosystems. Topics from basic principles to synthetic theories of stream ecosystems are covered, as well as applications for management of water quality, biological integrity, and fisheries in streams. Laboratory sessions and field trips provide hands-on experiences. Students work on term projects in small groups. Graduate students enrolling in AEcl 518 participate in bi-weekly discussions of primary literature. Team-taught with Dr. Thomas Isenhart.

Fisheries Science (AEcl 520) - This graduate-level course explores concepts, approaches and techniques for assessment of recreational and commercial fisheries. Topics range from basic principles to applications and from individual fish to entire ecosystems. Computer simulation modeling, group projects, and discussion of primary literature are emphasized.
