Description:
The objectives of the proposed research are to determine how the partitioning of toxic substances among dissolved and particulate phases affects bioaccumulation by a benthic suspension feeder, and how quantification of this phase-dependent bioavailability could be applied in environmental risk assessment. We will establish the role that ingestion of organic and inorganic particulate matter plays in toxicant uptake by oysters.

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.
