Research Emphasis:

I am a herpetologist at heart, though my current research extends into coastal ecology and island food web ecology. My research concentrates on the cross-ecosystem linkage support of top predators inhabiting barrier islands of the southeastern United States. I am using isotopic analysis (N and C) to examine the trophic levels and food sources utilized by top predators on Sapelo Island, Georgia. My study organisms include the American alligator (Alligator mississippiensis), wild hog (Sus scrofa), raccoon (Procyon lotor), Eastern Diamondback rattlesnake (Crotalus adamanteus), and various species of lizards (Plestiodon and Anolis). Surrounding much of the interior side of these barrier islands are coastal marshes dominated by marsh grass (Spartina alterniflora). Within these coastal environments, biomass and growth of associated fauna (e.g. fish, oysters, shrimp, snails) is often directly linked to the productivity of S. alterniflora and salinity gradient of the ecosystem. We are proposing to test the hypothesis that due to cross-system linkages in the form of freshwater subsidies from interior habitats (i.e. small and large islands) and protein from marine animals, populations of the before mentioned predators are able to persist in remarkably high population densities on barrier islands. If demonstrated, this could provide evidence to support the relationship of the health of coastal marsh ecosystems with the conservation and management of a wide variety of top predators inhabiting barrier islands of the southeastern United States.
