W. T. Edmondson is professor emeritus of zoology at the University of Washington. His research interests include the eutrophication of lakes, links between lake water quality and land development, and the ecology and taxonomy of Rotifera; he was instrumental in documenting the causes of eutrophication in Seattle's Lake Washington and in guiding policymakers on strategies to reverse damage to the lake. Edmondson is a member of the National Academy of Sciences and has received numerous professional awards, including the G. Evelyn Hutchinson medal of the American Society of Limnology and Oceanography, the August Thienemann–Einar Nauman Medal of the International Association for Theoretical and Applied Limnology, and the National Academy of Sciences' Cottrell Award for Environmental Quality. He received a B.S. degree in biological science and a Ph.D. degree in zoology from Yale University.

Thomas M. Frost is the associate director for Trout Lake Station, Center for Limnology of the University of Wisconsin, Madison. His prior work experience includes positions as an instructor and research associate in the Department of Biology at the University of Colorado, Boulder, and as director of the Lake Valencia Project's North American Field Group in Maracay, Venezuela. He earned a B.S. in biology from Drexel University and a Ph.D. in biology from Dartmouth College.

Eville Gorham is Regent's Professor of Ecology and Botany at the University of Minnesota.
