My primary area of research is in community and population ecology, particularly the importance of competition, plant-animal interactions, and environmental stresses on community organization in coastal and wetland habitats. Current projects include the following: (1) the mechanisms of competition in coastal plant communities, (2) the interactive effects of stress, disturbance, and competition in controlling species diversity, (3) the effects of grazing herbivores on wetland succession, (4) modeling the effects of global climate change and sea level rise on coastal communities, (5) the effects of fire on plant biodiversity, (6) the effects of hurricanes on plant communities, and (7) the factors controlling the invasion of cattails into the Florida Everglades. My projects involve field studies as well as field experiments, greenhouse and laboratory studies, computer simulations, and landscape modeling.
