Dr. Roger Bachmann's areas of research include limnology and aquatic
ecology. Dr. Bachmann joined the department in 1993. He had previously
served 30 years on the faculty of lowa State University where he taught
limnology and conducted research on lake eutrophication, nutrient cycling,
stream ecology, and quantitative relationships in lakes.
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 also served as an associate editor for the
special eutrophication issue of the American Society of Limnology and
Oceanography.
