Maine’s coastal ecosystems once supported prodigious abundances of wildlife that benefitted human communities for millennia before succumbing to multiple stresses during the industrial era. Today, it is possible to restore ecosystem structure and functionality for the benefit of wildlife and to regain some of the original ecological services for human benefit. Students examine Maine’s coastal ecosystems as socioecological systems and apply ecological principles to understand how society could promote ecological recovery and maintain resilient ecosystems and ecosystem services over the long term. Interdisciplinary seminar with focus on ecology and environmental history.

The MPBN documentary Desperate Alewives has been nominated for a New England Emmy in the category of Outstanding Environmental Program. The doc looks at how populations of alewife — also known as sawbelly, mooneye, gaspereau and big-eyed or spring herring — have plummeted, prompting research by a group whose members include Coastal Studies Scholar Ted Ames, professors Phil Camill, Guillermo Herrera, John Lichter and David Vail, and Environmental Studies Program Manager and geographic information systems analyst Eileen Johnson, many of whom are featured in the segment.
The Bowdoin group is collaborating with faculty from Bates and the University of Southern Maine on the project “Maine Rivers, Estuaries and Coastal Fisheries,” funded by the National Science Foundation’s Office of Experimental Program to Stimulate Competitive Research (ESPCoR) through a grant to the University of Maine’s Sustainability Solutions Initiative. Read more about the project on a website created by Hunter Clark ’13. The 35th Annual Boston/New England Emmy Awards, presented by the National Academy of Television Arts & Sciences Boston/New England, will be presented June 2, 2012, in Boston.
