Research Program


I have broad interests in evolution, particularly evolutionary ecology and evolutionary
genetics.  My students and I have carried out research on reproductive strategies and
larval life history in frogs.  We have also worked on the evolution of aposematism and
mimicry.  I am interested in molecular systematics and the use of phylogenetic trees to
inform analyses of ecology and adaptation. Evolutionary ecology and phylogenetics are
complimentary, because it is important to consider the effects of ecology on adaptation
in a historical context.  Similarly, phylogenetic information can be used to investigate the
influence of ecological and social factors on adaptation in comparative analyses.  Most
of our field and laboratory research has focused on the poison frogs of the family
Dendrobatidae, a group of toxic frogs in Central and South America.  These frogs vary
in diet, coloration and toxicity, making them excellent candidates for research on
aposematism and mimicry.  The reproductive ecology of these frogs is also interesting
and complex, involving territoriality, intra-sexual competition for mates, prolonged
courtship, mate choice, long term associations between males and females, extensive
parental care by one or both sexes, trophic egg-feeding, and larval cannibalism.  
The wide spectrum of variation in life histories across the poison frog family make this
group an excellent system for comparative studies.

I am also interested in evolutionary approaches to human health and behavior.
Evolutionary biology is highly relevant to many issues crucial to human health and
disease, yet few medical researchers take an evolutionary perspective. Vast amounts
of data relevant to issues of central interest in evolutionary biology, such as the
evolution of senescence and parasite-host coevolution, are being generated by
biomedical researchers, but use of these data to test evolutionary hypotheses is
uncommon. My collaborators and I have attempted to develop hypotheses relating
specific conditions to environmental, social and genetic factors in an evolutionary
framework. We are also attempting to test specific hypotheses using molecular
evolutionary genetic analyses of genomic data available from public databases such
as GenBank.

Please join us for a course on tropical biology at the world's
premier location for tropical research:

Gamboa, on the Panama Canal, and nearby sites. Gamboa is at the heart
of the Smithsonian Tropical Research Institute's research and educational
mission. Courses involve lectures, field trips and individual research projects.  
We take advantage of ready access to premier rain forest reserves with
abundant tropical wildlife and stunning biodiversity. We provide up close and
personal experiences with cutting-edge research done by leading tropical
biologists from STRI and from around the world.  Several courses are available,
including: Terrestrial Tropical Ecology (2 wks) and Tropical Marine Ecology
(2 wks), for a total of up to 10 credit hours (undergrad or grad credit).  
Courses are run through the Summer Study Abroad Program at East Carolina
University, but biology students from any university are eligible. The 2012
courses will run from June 25th to July 27th.  Please contact Kyle Summers
(summersk@ecu.edu), Susan McRae (mcraes@ecu.edu) or Joe Luczkovich
(luczkovichj@ecu.edu) for further info.
