About the Lab 

The Marine Invasions Research Lab is a national and international center for research on biological invasions in coastal marine ecosystems. Biological invasions (the establishment of species beyond their historical range) are a major force of ecological and evolutionary change. Invasions are fundamentally changing the structure and function of ecosystems around the world and are impacting many dimensions of human society. The observed rates and impacts of new invasions have increased dramatically in recent time. ...more

Parasites, Crabs, and Slippery Eels – Highlights from the 2014 Chesapeake Bay Parasite Project

It was another great year for the Chesapeake Bay Parasite Project. Including five staff and an intern, 50 people participated in two events, one in June and one in August. We collected hundreds of mud crabs, found parasites, worked in the rain, sunshine, and even enjoyed music from a live band at Harrington Harbor. We saw eels, many species of fish, blue crabs, large jellyfish, and at one site witnessed an osprey catch a very large fish that he/she could just barely lift from the water. We had great volunteers who worked really hard, some putting in 10-hour days! Thank you to everyone who came out. Full Story
