Description:
Using paleoecological techniques, to reconstruct the history of the trophic structure of the Chesapeake Bay over the past 2000 years, in order to compare the effects of changes in climate during the approximate 200 year Medieval Warm Period which occurred about 1000 years ago and the Little Ice Age which lasted for a few centuries following the warm period, with anthropogenic changes including deforestation, agriculture and urbanization which have occurred over the past two to three centuries.

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.
