Erwin , R. Michael		Research Interests

Research Professor and Wildlife Biologist, Patuxent Wildlife Research Center, U.S.G.S., Laurel, Maryland; Ph.D. University of Maryland, 1975. Population and community ecology, behavioral ecology, conservation biology, avian biology. 351 Clark Hall 434-924-3207 rme5g@virginia.edu		My research interests range from basic questions concerning the evolution of coloniality to highly applied questions of habitat management and restoration for coastal wildlife populations. My work has concentrated on metapopulation dynamics of a number of avian species, habitat choice and variability, and factors influencing reproductive success. I have also directed projects involving landscape-scale experimental manipulations of habitats in coastal wetlands to evaluate wildlife responses. Of recent interest is a project to model the long-term implications for wildlife of coastal sea level rise and projected changes in Atlantic coastal marshes. I feel it is important to keep the broad (landscape) perspective in one's research even if much attention is devoted to small-scale local experimentation.
