In 1963 Dr. Roger Bachmann joined Dr. Kenneth Carlander as the second faculty member in fisheries, in the Fisheries and Wildlife Section of the Department of Zoology and Entomology. Dr. Bachmann served as the first chairman of the newly formed Department of Animal Ecology in 1975. He retired from the Department of Natural Resource Ecology and Management in 1993.
Dr. Roger Bachmann's areas of research include limnology and aquatic ecology. He served 30 years on the faculty of Iowa State University where he taught Limnology, Ichthyology and Herpetology, Fish Propagation and Pond Management, Advanced Limnology, Ecological Energetics, Stream Ecology and conducted research on lake eutrophication, nutrient cycling, stream ecology, and quantitative relationships in lakes. He supervised the completion of 10 PhD and 34 M.S. students.
In Florida he has looked at relationships between a lake trophic state and fish populations, scientific bases for determining eutrophication in large Florida lakes, the application of the theory of alternative stable states to shallow Florida lakes, the role of wind in resuspending lake sediments, the use of biocriteria for evaluating lakes, and lake restoration strategies. He is also involved with others in analyzing the long-term database on Florida lakes collected by the Florida LAKEWATCH program.
Dr. Bachmann regularly presents papers at meetings of the Florida Lake Management Society and the North American Lake Management Society. In 2004, he was an invited speaker at the Shallow Lakes Symposium at the American Fisheries Society in Madison, Wisconsin. He currently serves as an associate editor for the special eutrophication issue of the American Society of Limnology and Oceanography.
