TEACHING AND RESEARCH AREAS

Teaching effort emphasizes plankton ecology. One major research thrust examines how Protist behavior and physiology influence the ecology of selected species. As a participant in the ECOHAB: Florida Project, we are investigating how Karenia brevis uses cues related to its circadian rhythms, its internal physiological/biochemical state and its external environmental exposure to determine cell location in the water column and thus to transporting current regimes on the west Florida shelf. Other ECOHAB funding support associated laboratory work using mesocosms and field work using a programmable Lagrangiun drifter termed the K. breve population mimic. Pfiesteria project, we are investigating how cells may use chemotaxis to locate fish prey. A second major research thrust is to develop a capability to monitor plant nutrients in the world ocean using remotely sensed temperature and to apply this capability to an improved interpretation of phytoplankton biomass and production based on remotely sensed ocean color.
