Alan P. Covich is a professor and director of the Institute of Ecology at the University of Georgia. He was previously a professor in the Department of Fishery and Wildlife Biology at Colorado State University and in the Department of Zoology at the University of Oklahoma. Dr. Covich’s research focuses on ecosystem functioning in temperate and tropical streams, including assembly of food webs, predator-prey dynamics and chemical communication, and crosssite comparisons of drought impacts on drainage networks. For the past 16 years, he has conducted research in the Luquillo Experimental Forest Long Term Ecological Research (LTER) site in Puerto Rico. Dr. Covich is a past president of the North American Benthological Society and the American Institute of Biological Sciences. He has an A.B. from Washington University and an M.S. and Ph.D. in biology from Yale University.

Steven P. Gloss is an ecologist with the U.S. Geological Survey’s Southwest Biological Science Center and is based in the school of natural resources at the University of Arizona in Tucson. Dr. Gloss was previously the program manager for biological sciences at the Grand Canyon Monitoring and Research Center in Flagstaff, Arizona and a professor of zoology and physiology at the University of Wyoming. He is a former member of the Water Science and Technology Board (WSTB), served on the National Research Council (NRC) Committee on Grand Canyon Monitoring and Research, and chaired the NRC Committee on the Missouri River Ecosystem Science.

Carlton H. Hershner, Jr., is an associate professor of marine science at the College of William and Mary and directs the Center for Coastal Resources Management at the Virginia Institute of Marine Science. His primary research interests are in tidal and nontidal wetlands ecology, landscape ecology, and resource management and policy issues. Dr. Hershner also conducts research in resource inventory procedures, habitat restoration protocols, resource management “expert system” development, and science policy interactions. He recently served as a member of the NRC Panel on Adaptive Management for Resource Stewardship. Dr. Hershner has a B.S. in biology from Bucknell University and a Ph.D. in marine science from the University of Virginia.

John P. Hoehn is a professor of environmental and natural resource economics at Michigan State University. His primary research interests include methods for valuing environmental change, economic analysis of policies and incentives for ecosystem preservation, water quality demands, and natural resource damage assessment. Dr. Hoehn received an A.B. in anthropology from the University of California, Berkeley, and an M.S. and Ph.D. in agricultural economics from the University of Kentucky.
