作者介紹 Dr. Andrew Muir is Science Director for the Great Lakes Fishery Commission, a treaty organization formed by the 1955 Convention on Great Lakes Fisheries between Canada and the United States. He is responsible for administering fishery and sea lamprey research programs and a science transfer program throughout the Great Lakes Basin. He earned a Ph.D. in Fisheries Science from Purdue University (2008) and an M.Sc. (2004) and B.Sc. (2000) in Zoology from the University of Guelph. His current research is focused on the patterns and processes generating and maintaining diversity in deepwater food webs of North American large lakes, invasive species, and ecological connectivity. He has been fortunate to work with a number of great scientists, sampling and experiencing lake charr throughout their distribution, including the Mackenzie Great Lakes of the Northwest Territories.Michael Hansen recently retired from the US Geological Survey, Hammond Bay Biological Station, where he served as supervisor and research fishery biologist. He previously held positions in fishery science and management at the University of Wisconsin-Stevens Point (1996-2013), US Fish & Wildlife Service, Great Lakes Science Center (1990-1996), Wisconsin Department of Natural Resources, Bureau of Fisheries Management (1984-1990), and EA Engineering, Science & Technology (1981-1984). He earned a PhD from Michigan State University (1994), MS from Cornell University (1983), and BS from the University of Wisconsin-Stevens Point (1979). He has published extensively on the management and ecology of lake charr, among his 135 journal articles, book chapters, and agency publications.Stephen Riley recently retired from the U. S. Geological Survey Great Lakes Science Center in Ann Arbor, Michigan, where he served as a research fishery biologist. Stephen earned a B.Sc. (1984) and M.Sc. (1986) in Biology from the University of Waterloo and a Ph.D. in Fishery and Wildlife Biology from Colorado State University (1992). He has conducted research on salmonid ecology and management throughout North America.Dr. Charles "Chuck" Krueger is the T.F. Waters Professor of Aquatic Ecology and Conservation at Michigan State University, and former Director of the Great Lakes Acoustic Telemetry Observation System. In addition, he has worked for the Wisconsin Department of Natural Resources, U.S. Fish and Wildlife Service, Great Lakes Fishery Commission, and Cornell University. He is keenly interested in discovering the ecological characteristics of fish species of conservation concern and linking those results to their restoration, conservation, and wise use in fisheries. The discovery process is made through a variety of disciplines including investigating morphology, trophic ecology, behavior, and population genetics.
