Description:
To determine the accumulative effects of current, increased and decreased levels of multiple stressors on a representative coastal system; to determine how ecological complexity, variability, and spatial structure affect the response of a representative coastal system to multiple stressors and the ability of managers to predict that response; and to determine how a variety of management options may affect both the biota and the economic value of the system.

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.
