Description:
The overall goal of this research is to measure the patterns of delivery and viability of species transferred among U.S. ports in the ballast water of domestic ship traffic. We propose to measure directly the volume of ballast water delivered to selected Atlantic ports from other domestic ports, the abundance and diversity of organisms associated with that ballast water, and the survival of these organisms during transit and upon arrival.

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.
