Description:
The objective of the proposed study is to test the hypothesis that planktonic and benthic trophic dynamics and benthic-pelagic coupling control the speciation, transport, bioavailability, bioaccumulation and toxic effects for synthetic organic contaminants in Chesapeake Bay. We propose to develop a numerical simulation model of the key ecological processes: to integrate data collected by various investigators in the Bay region; to test hypothesis about interactions between trophic dynamics and contaminant fate/effects; and to provide information needed for Ecological Risk Assessment.

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.
