I am an evolutionary behavioral ecologist studying the impact of climate change and behavioral adaptations in marine animals. My teaching and research focuses on understanding the impact of habitat loss on the conservation of marine communities. I enjoy training graduate students, undergraduate students and teachers in the methods of experimental field ecology.
Shallow water marine communities are one of the most threatened ecosystems on the planet. Changes in water quality due to nutrient runoff, freshwater diversion, ocean acidification and global warming are having major impacts on the structure and function of these important communities and the fisheries they support. My research focuses on studying the impact of habitat loss and drought on blue crabs, lobsters and reef fishes along the southeastern US. Through a combination of field surveys, manipulative experiments, laboratory behavioral observations and individual-based modeling our research attempts to build models that can accurately forecast the response of these species to future changes in climate and habitat quality. Behavioral adaptations may be the most important attributes for resilience to habitat loss so more work is needed to understand how behavioral resilience is generated and maintained in these species.
Extension and Outreach
I am actively involved with state (SCDNR & CISA) and federal (USGS & NIDIS) scientists to develop better tools for forecasting the future impacts of climate change on marine resources. I have developed an individual-based population model of blue crabs that forecasts future crabs landings for the state of South Carolina. Integrating this model with coastal drought indices will help us to forecast how drought is likely to impact future commercial fisheries landings.
