- Ph.D., Limnology/Zoology, University of Wisconsin-Madison
Dr. Karen Wilson is an associate research faculty with the Department of Environmental Science and Policy. She teaches ESP 341 Limnology and ESP 412 Field Ecosystems Ecology in alternate fall semesters, and ESP 303 Wetlands Ecology and ESP 360 Water Quality in alternate spring semesters, as well as other ESP courses. Please check out Visiting Maine Wetlands, an on-going project of the Wetlands Ecology course, and Constraints on River Restoration, a project from the 2011 Senior Seminar students.
Karen has a Ph.D. in Limnology/Zoology from the University of Wisconsin-Madison where she studied the long-term impacts of an invasive crayfish on lake communities. Since receiving her degree, Karen has taught at a small liberal arts college in the Midwest and worked as a post-doctoral fellow at the Department of Zoology, University of Toronto, and the Ontario Ministry of the Environment.
Undergraduate students and graduate students (in USM's Masters of Biology program) conduct resarch in Karen's lab (and Maine's lakes, streams and ocean).
Karen is currently the lead Principle Investigator on a project investigating variation in habitat use by juvenile river herring in the Penobscot River, Maine, funded by Maine Sea Grant and USM. This project is in collaboration with scientists from NOAA Fisheries, the University of Maine, USM and SUNY-ESF, and is part of a larger effort to assess the effects of dam removal on the Penobscot River Estuary food web.
She is one of 20 faculty from three states working on an NSF-funded project called The Future of Dams (Strengthening the Scientific Decision-making about Dams: Multi-scale Coupled-systems Research on Ecological, Social and Economic Tradeoffs). She serves as the project "river herring expert."
Karen is also a collaborator on the Maine EPSCOR project SEANET in which she studies trophic interactions in estuaries and bays.
Past projects include the Diadromous Species Restoration Research Network (DSRRN), a research coordination network funded by NSF, and the interdiscipinary Sustainability Solutions Initiatives project investigating economic and ecological connections between Maine rivers, estuaries and coasts in the Kennebec-Androscoggin River System using anadromous river herring as a common currency between these habitats and systems.
