Lobster Research at Assumption College Garners Grant:
Aggression and Dominance in lobsters will be studied


February 7, 2003—Assumption College professor Dr. Stuart Cromarty, whose research includes, working with the American Lobster, has recently been awarded a $250,000 National Science Foundation grant through a joint proposal submitted with Dr. Gabriele Kass-Simon from the University of Rhode Island.

The purpose of Dr. Cromarty's research is to identify and analyze the role and nature of steroid hormones in aggressive behavior. Aggression is a vital component of the survival strategies of all animals and is used in the acquisition of food, mates, and territory. The American lobster is an ideal animal model to use for scientific experiments due to its aggressive nature.

"We expect to show that steroids not only alter the internal aggressive state of an animal, but are also used as signaling tools to modify the behavior of an opponent in an aggressive interaction. These steroids are released in the urine during fights, are smelled by each animal, and signal who is bigger, stronger and dominant, and who is the winner and loser.”

Undergraduates from Assumption College will be paired with doctoral candidates from the University of Rhode Island and will work with Drs. Cromarty and Kass-Simon on various aspects of the research project. Students will be exposed to state-of-the-art techniques which include the latest immunocytochemical (antibody staining), neurophysiological (molecular probes and electrical brain recordings) and behavioral techniques. Students will then continue their projects and research during the academic year at Assumption College.

The grant was accepted with full funding support for three years starting in June 2003. The three-year award totals approximately $250,000 and is equally distributed between the two institutions. It also includes travel expenses for the undergraduates to the annual Society of Neuroscience meeting and a local conference at the Marine Biological Laboratory in Woods Hole, Massachusetts. On the University of Rhode Island side, the grant will support two doctoral candidates and one undergraduate student each summer.
