Control of copepod populations by predators: larval ctenophores
Principal Investigator:

Description:
The objective of the proposed research is to determine predation rates on Acartia tonsa nauplii and copepodites due to tentaculate larval Mnemiopsis ctenophores. These predators may be extremely important in controlling copepod population densities. This research examines predation not yet addressed in my ongoing research on the impacts of medusae and adult ctenophores on copepod populations. This research should complete examination of the major pelagic predators on Acartia copepods in the mesohaline region of Chesapeake Bay.

Exploring the Use of Benthic Microbial Fuel Cells to Remove Sulfide While Harvesting Energy from Oyster Aquaculture Biodeposits
Oyster aquaculture is a rapidly growing industry in Maryland’s Chesapeake waters which stimulates economic activity and may provide a host of ecosystem benefits. A potential concern associated with the intensification of the oyster aquaculture is the local production and accumulation of oyster biodeposits, which can lead to a porewater sulfide accumulation and declining bioturbation, symptoms of declining ecosystem function. Sulfide is naturally removed from the seafloor by the interactions between bioturbating infauna and sulfide oxidizing bacteria.
