Although she received her undergraduate training in chemistry, Julie A. Robinson shifted her interest to biology and received B.S. degrees in chemistry and biology from Utah State University in 1989. She conducted field research on American Avocets and Black-necked Stilts from 1991 to 1994 and received a Ph.D. in ecology, evolution, and conservation biology from the University of Nevada, Reno (1996). After brief postdoctoral research at the University of Houston, she joined an interdisciplinary team of Earth scientists at the National Aeronautics and Space Administration’s Johnson Space Center in 1997. She is currently focusing on applications of remote sensing to ecology and conservation biology. Her ongoing research uses astronaut handheld photography to identify and monitor landuse and environmental change around the globe. Current address: Office of Earth Sciences, Johnson Space Center, 2400 NASA Road 1, C23, Houston, TX 77058. E-mail: jarobins@ems.jsc.nasa.gov.
J. Michael Reed received his Ph.D. from North Carolina State University (1989) conducting studies of the population ecology of the endangered Red-cockaded Woodpecker (Picoides borealis). After conducting research on behavioral and population biology of Spotted Sandpipers, he returned to the study of endangered species when he initiated research on the Hawaiian Stilt in 1992. Other research efforts have included studies of population dynamics and conservation of neotropical migrants in desert riparian areas in Nevada. He is currently continuing research as Assistant Professor of Biology at Tufts University. Current address: Department of Biology, Tufts University, Medford, MA 02155. E-mail: mreed@tufts.edu.
Lewis W. Oring received his Ph.D. in 1966 from the University of Oklahoma. Following research on shorebirds in Europe, he began studying shorebirds at the University of Minnesota in 1967 and the University of North Dakota in 1968. From 1969 to 1991 he conducted research on the social systems of sandpipers, developing a long-term field study of polyandrous Spotted Sandpipers in northern Minnesota. Since 1991, he has continued his studies of shorebirds at the University of Nevada, Reno, focusing on Killdeer, American Avocets, and Black-necked Stilts. He is Professor of Environmental and Resource Sciences at the University of Nevada Reno. Current address: University of Nevada, Reno, Department of Environmental and Resource Sciences/186, 1000 Valley Rd., Reno, NV 89512. E-mail: oring@ers.unr.edu.
In the course of his graduate research at University of California, Davis, Joseph P. Skorupa studied the foraging ecology of endangered Red-cockaded Woodpeckers (M. S. 1979), and the effects of timber harvesting on the socioecology of rain forest primates in Africa (Ph.D. 1988). From 1978 to 1986 he served intermittently as an avian ecologist for the Denver Wildlife Research Center of the U.S. Fish and Wildlife Service, studying methods for control of avian damage to agricultural crops. Since that time he has focused his research on the effects of agricultural contaminants on birds, working from 1988 to 1991 at the Patuxent Wildlife Research Center, and since 1991 as Senior Biologist in the Division of Environmental Contaminants, U.S. Fish and Wildlife Service. He is currently USFWS Technical Coordinator for the National Irrigation Water Quality Program. Current address: USFWS Sacramento Field Office, 3310 El Camino Ave., Suite 130, Sacramento, CA 95821.
