Research Interests
My general interests include behavioral ecology and animal behavior with an emphasis on the evolution of behavior. I am particularly interested in mating behavior, sexual competition, and mate choice. My previous work tested hypotheses for the evolution of both pre- and post-copulatory mate guarding in the blue crab. More recently, I have become interested in habitat use particularly as a measure of habitat quality and of the potential interactions between species. I am also interested in the effect of invasive species on native species and habitats.
Current Research Projects
Currently, I am examining the potential for fisheries-induced sperm limitation, within and among populations differing in fishing pressure, and its influence on female reproductive output in blue crabs.
I am also examining the influence of bulkheads on species diversity, organism abundance, and habitat quality in Barnegat Bay, NJ.
