Karen Wilson 
Biographical Sketch:
Karen Wilson is an assistant research faculty with the Department of Environmental
Science and a scientist in the Aquatic Systems Research Group at USM. She is
currently teaching ESP 341 Limnology and will teach ESP 303 Wetlands Ecology
in the spring of 2006.
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, Toronto, Ontario. Karen's current
research focuses on:
- freshwater-marine linkages and anadromous alewife
- saltmarsh restoration and impacts on marsh-marine linkages
- freshwater crayfish in Maine
