Research interests

      I am interested in questions at the intersection of behavioral ecology, physiological ecology, and life history evolution. I use a combination of field, laboratory, and modeling experiments to address questions in these areas.

 

          Effects of age on mate choice decisions: In collaboration with Dr. Daniel Promislow at the University of Georgia, I am using genetic algorithm models to examine the evolution of female preference based on male age, as well as the effects of female age on mate choice decisions. We are also interested in how female preferences can lead to changes in life histories and how life histories may alter the evolution of female preferences.

 

            Effects of sex ratio on male reproductive allocation: In collaboration with Dr. Larry Blumer, I am looking at the effects of sex ratio on energy allocated to spermatophores in the bean beetle, Callosobruchus maculatus. Because male reproductive investment is high, we predict that males will alter their allocation to spermatophores depending the number of available mates.

 

         Other recent or on-going projects:

         •       Effects of English ivy on seedbank formation and germination

         •       Effects of method of English ivy removal and seed bank restoration on regeneration of vegetation in a southeastern Piedmont forest

         •       Relationship between privet density and bird diversity

         •       Comparison of fish and macroinvertebrate based indices of stream water quality

         •       Relative importance of body size and dominance on female mate choice in convict cichlids

         •       Effects of packing constraints on the relationship between egg size and total allocation to reproduction

         •       Environmental pools of Toxoplasma

         •       Population viability analysis of the smalltooth sawfish

Curriculum development

      I am working with Dr. Larry Blumer at Morehouse College on an NSF-funded project to develop the bean beetle Callosobruchus maculatus as a model system for undergraduate laboratories in ecology, evolution, and animal behavior (www.beanbeetles.org).
