Description:
The main objective is to test the hypothesis that pollutant stress may predispose aquatic organisms to infectious diseases or accelerate the progression of the disease. The host-parasite system proposed is Crassostrea virginica - Perkinsus marinus; the environmental toxicants under study will include a lower MW polycyclic aromatic hydrocarbon (naphthalene) and tributyltin. An attempt will be made to associate pollutant-induced changes in disease progression to changes in cell-mediated immune function.

Developing a habitat model for mysids, an important link in Chesapeake Bay food webs
Mysids are important mesozooplankton prey for many species of fish in Chesapeake Bay and are an important link in transferring energy from lower to upper trophic levels. Mysids also serve as biological vectors for benthic-pelagic coupling due to their diel vertical migration and omnivorous prey-switching behavior, which makes mysids important regulators of food web architecture. Despite their central role in coastal food webs, surprisingly little is known about mysid ecology and dynamics in Chesapeake Bay.
