“Marine Invaders: Stopping the Spread of Exotic Species” is last of four talks on conservation biology this month at the aquarium. The Wednesday afternoon talks are part of the Woods Hole Science Aquarium High School Intern Program, which is sponsored jointly by NOAA Fisheries Service and the Marine Biological Laboratory. Invasive species are plants or animals that move into new areas and displace native species. In some areas, marine invaders now make up one-fifth of the total species present. Pederson will talk about a variety of invaders, including sea squirts, the most successful marine invaders in New England waters. She will describe efforts to prevent new invaders and to reduce the impact of invading species that have already settled in our waters.

Pederson received her Ph.D. from Clark University in marine ecology. As director of the MITSG Center for Coastal Resources at the Massachusetts Institute of Technology Sea Grant College Program, she makes scientific and technical information accessible to policy makers, students, and the public. Her research interests are marine bioinvasions and coastal pollution. She is a member of two ICES Working Groups on marine introductions and co-chair of Northeast Aquatic Nuisance Species Panel (NEANS). She has organized rapid assessment surveys for New England, convened International Marine Bioinvasions Conferences and Workshops, and edited several conference proceedings, including a Special Issue of Biological Invasions.


NOAA’s National Marine Fisheries Service is dedicated to protecting and preserving our nation’s living marine resources and their habitat through scientific research, management and enforcement. NOAA Fisheries provides effective stewardship of these resources for the benefit of the nation, supporting coastal communities that depend upon them, and helping to provide safe and healthy seafood to consumers and recreational opportunities for the American public.

The National Oceanic and Atmospheric Administration, an agency of the U.S. Commerce Department, is dedicated to enhancing economic security and national safety through the prediction and research of weather and climate-related events and providing environmental stewardship of our nation’s coastal and marine resources. Through the emerging Global Earth Observation System of Systems (GEOSS), NOAA is working with our federal partners and nearly 60 countries to develop a global Earth observation network that is as integrated as the planet it observes, predicts and protects.
