Dr. David Edds is an aquatic ecologist interested in the community structure of aquatic environments. At Emporia State University, Dr. Edds is Professor of Biological Sciences, and teaches Aquatic Biology, Ichthyology, Stream Ecology, Fisheries Management, Zoology, and Scientific Writing.
Dr. Edds earned a Ph.D. in Zoology from Oklahoma State University with a dissertation entitled "Multivariate analysis of fish assemblage composition and environmental correlates in a Himalayan river -- Nepal's Kali Gandaki/Narayani," based on research conducted in Nepal in 1984-86, and summarized in Copeia 1993:48-60, Odonatologica 22:213-221, and the Journal of the Nepal Natural History Museum 9:41-46; 10:1-12; 10:13-22; and 11:1-14.
Dr. Edds' major professor at OSU was Dr. A.A. Echelle, who also supervised his master's research on "The genetic structure of endangered desert fishes: natural versus captive populations," which used electrophoresis to compare genetic variability of natural and captive populations of Cyprinodon bovinus, C. elegans, and Gambusia nobilis. Results were published in Copeia 1987:668-681, Conservation Biology 3:159-169, and Transactions of the American Fisheries Society 118:441-446.
Dr. Edds' main research interests are with fish ecology and conservation biology, but he also studies the ecology of freshwater mussels and aquatic turtles. Much of his recent research in Kansas has centered on the conservation of threatened and endangered species, including the Neosho madtom (a threatened catfish); the Neosho mucket, Ouachita kidneyshell, and western fanshell (mussels); and the northern map turtle and alligator snapping turtle. Other research has examined the ecology of reservoir fishes, including native and nonindigenous species, the effects of dams and pollution on riverine communities, and spatiotemporal patterns/environmental correlates of fish assemblage structure.
Dr. Edds' principal research addresses the distribution and ecology of fishes of Nepal. He was a Peace Corps fisheries volunteer in Nepal in 1977-79, and a student Fulbright scholar in Nepal in 1984-85. During sabbatical leave from ESU, and with support from National Geographic and a faculty Fulbright research grant, Dr. Edds traveled to Nepal in 1996 to continue long-term research on fish ecology in the Himalayas. Results of these studies have been published in the Journal of Freshwater Ecology, Biochemical Systematics and Ecology, Ichthyological Exploration of Freshwaters, and Zootaxa. His collections of Nepal fishes are held in the Tribhuvan University Natural History Museum, Kathmandu, and in the Fisheries Development Division, Kathmandu, as well as in the Collection of Vertebrates at Oklahoma State University, Stillwater, and the University of Kansas Museum of Natural History, Lawrence.
Dr. Edds graduated with a B.S. in Biology from the University of Kansas in 1977, and an A.A. in Liberal Arts from Independence Community College in 1974. He is a past-president of the Kansas Chapter of the American Fisheries Society and the Kansas Herpetological Society, a past member of the Board of Governors of the Southwestern Association of Naturalists, and is a former associate editor for that society's journal. His membership in professional societies includes the American Fisheries Society, American Society of Ichthyologists and Herpetologists, Society for the Study of Amphibians and Reptiles, The Chelonian Conservation Society, Southwestern Association of Naturalists, and Kansas Academy of Science.
