Description:
By employing oyster larvae and spat as experimental organisms, we propose to develop and test biochemical and molecular procedures for assessing the potential toxicity of selected metals and organic pollutants. Specific objectives include: (i) cloning the cDNAs of hsp genes, (ii) developing quantitative dot blot assays for MT and hsp mRNAs, and (iii) studying the expression of MT and hsp genes and the synthesis of their gene products during various developmental stages in response to induction by metals and organic compounds.

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.
