Research Interests:

Ecology, Animal Behavior, Evolution

My research is in the areas of behavioral ecology and evolutionary biology. Currently my students and I are studying mate choice, sexual selection, and the consequences of mate choice in animals. We are evaluating the effects on neuropeptides on the female mate choice in sailfin mollies, Poecilia latipinna. The molly studies are in collaboration with Dr. Christopher Beck (Emory University). In separate studies, we are evaluating the reproductive-behavioral consequences of induced social stress in convict cichlids, Cichlasoma nigrofasciatum.

We also are conducting studies on the behavior, ecology and evolutionary biology of insects. In collaboration with Dr. Christopher Beck, we are developing undergraduate laboratory teaching protocols with the Bruchid bean beetle, Callosobruchus maculatus. Visit our website: www.beanbeetles.org for access to these teaching resources. Other studies are evaluating competition between two parasitoids, Melattobia and Nasonia. This work is being conducted in collaboration with Dr. Robert Matthews (University of Georgia). In another study, we are evaluating the rapid induction of chemical defenses in ornamental tobacco, Nicotiana alata, and using tobacco hornworm larvae, Manduca sexta, as a biological indicator for induced chemical defenses.

My previous studies have focused on the evolution of parental care in fishes, the ecology of male parental care in the brown bullhead (a North American catfish) Ictalurus nebulosus, kin recognition in fishes, and the dynamics of mate choice and sexual selection in animals. In addition to these areas of research, students who wish to work with me may pursue investigations in other areas of ecology and environmental biology (broadly defined). Past studies conducted by students have been on the causes for growth variation in loblolly pine trees, factors influencing rates of domestic compost decomposition, bean beetle host selection and avoidance of competition, causes for birth weight variation in humans, patterns of human infant facial resemblance, social behavior and population genetics of fiddler crabs, patterns in plant defenses in response to herbivory, and evaluation of behavioral toxicology assays.
