David S. Wethey
Professor of Biological Sciences
and Marine Science
Population and Community Ecology, Biogeography, and Rocky Intertidal Ecology
Dr. Wethey's research interests include biogeography, population dynamics, predator-prey and competitive interactions, conservation genetics, and the mechanisms by which organisms escape the physics of their habitats. He uses a combination of field and laboratory experiments and modeling to examine these processes. His work on population dynamics involves the application of difference and differential equation models to age structured populations, including barnacles, annelids, copepods, and fish. His work on predator-prey interactions has examined the influence of fluid dynamics on the transport of odor plumes used for prey detection by aquatic predators. His work on animal behavior has used non-invasive field and laboratory methods including medical ultrasound and low frequency pressure transients to detect activities of animals living within sediments. His work on biogeography has used field experiments and biophysical modeling to determine the mechanisms responsible for setting geographic limits of species. His field studies are currently being carried out on the Atlantic and Pacific coasts of North America, the Pacific coast of Asia, and the Atlantic coast of Europe.
His current projects include
1. field, remote sensing, modeling and forecasting studies of the mechanisms responsible for setting the geographic limits of intertidal barnacles, mussels, and infauna, with Drs. Jerry Hilbish, Brian Helmuth, Sarah Woodin, and Venkat Lakshmi (Funding: NASA, NOAA-Ecofore, NSF),
2. field and laboratory studies of the subsurface activities of infaunal worms and clams, and their effects on porewater geochemistry, nutrient cycling, and bacterial populations with Drs Sarah Woodin (USC), Rick Lovell (USC), Lubos Polerecky (Max Planck Institute for Marine Microbiology, Bremen, Germany), Nils Volkenborn, and George Matsui (Funding: NSF)
