SES Distinguished Scientist Seminar Series
10/01/04
Grazing, Browsing and Ecosystem Functions
John Pastor – University of Minnesota Duluth
3:00 PM Whitman Auditorium
John Pastor is interested in the effects of foraging and herbivory by large herbivores (e.g. moose and beaver) on plant productivity and nutrient cycling in forest soils. He has focused much of his research on northern ecosystems, including Isle Royale in Lake Superior and Voyageurs National Park northern Minnesota. Climate change is expected to be most pronounced at higher latitudes, and Pastor’s work also explores potential impacts of warming on the function and composition of northern peatlands.
Pastor is Professor in the Department of Biology and Senior Research Associate in the Center for Water and the Environment at the University of Minnesota Duluth, where he also serves as Director of Graduate Studies. He received his BS in Geology at the University of Pennsylvania, and his M.S. and Ph.D. from the University of Wisconsin in Soil Science and Forestry.
Pastor has authored more than 100 scientific papers, contributed to numerous books and written more than 20 popular articles on topics ranging from skunk cabbage and blowflies to spring warblers. He has served on many review committees and research panels for the National Science Foundation, National Academy of Sciences, Department of Interior, Department of Agriculture, Environmental Protection Agency, NASA and others. Also, he has testified for two U.S. congressional committees regarding the Voyageurs National Park and Boundary Waters as well as testifying on the effects of global climate. In 1999, Pastor was elected an Honorary Life Member of the Finnish Society of Forest Science. He is also the first recipient of the Chancellor’s Distinguished Research Award from the University of Minnesota Duluth.
