Stephen M. Coghlan, Jr.
Assistant Professor of Freshwater Fisheries Ecology Dr. Coghlan joined the faculty of the Wildlife Ecology Department in September 2006, with research interests encompassing individual- and community-level processes relating to applied fisheries ecology and management. He is working closely with state and federal agencies in building a collaborative research program around issues important to the ecology and management of Maine’s freshwater fish and aquatic habitats, focusing on the interactive ecology of native and exotic species, the effects of land-use patterns on aquatic communities and habitats, niche partitioning and interspecific competition, and bioenergetic implications of resource selection. Specifically, current research projects include the interactive ecology of smallmouth bass, Atlantic and landlocked salmon, and brook trout; effects of dam removal on fish community structure and function of the Sedgeunkedunk Stream watershed; effects of riparian forest structure on brook trout bioenergetics in the Northern Forest; utility of CWD placement and fish relocation in conserving headwater populations brook trout; reconstructing migratory history of putative anadromous brook trout in Acadia National Park; and migratory ecology of riverine populations of round whitefish. Dr. Coghlan teaches courses in Freshwater Fisheries Management and Statistical Ecology, and is the faculty advisor for the university's Student Subunit of the American Fisheries Society and the departmental Graduate Student Seminar Committee. His undergraduate and graduate studies at the SUNY College of Environmental Science and Forestry focused on the juvenile ecology of landlocked Atlantic salmon in Lake Ontario tributaries, including competition with exotic salmonines, bioenergetics, feeding patterns, and demographic responses along pollution and landscape gradients. He also studied the distribution and abundance of fish and insects across central New York streams and Adirondack ponds, and taught courses in fisheries biology, ichthyology, aquatic entomology, and Adirondack field ecology. As a post-doctoral researcher, Dr. Coghlan and colleagues at Arkansas State University used otolith chemistry to infer life-history, migratory patterns, and population structure of trout in Arkansas tailwaters, and have applied these techniques towards investigating natal homing in mayflies.
