Current Research Interests
1. Most recently my research centers on the ecology of tropical reptiles. I am interested in the influence of history (phylogeny), foraging mode, biogeography, and morphology (including body size) on the ecological attributes of reptiles. The importance of foraging mode and history to the evolution of ecological traits has only recently been appreciated. Because of the high taxonomic and ecological diversity of tropical reptiles, they provide excellent models for identifying the evolutionary determinants of ecological patterns. Identification of patterns is critical to the design of realistic field experiments to test hypotheses generated by comparative studies.
2. As the result of field studies in the Brazilian and Ecuadorian Amazon basin, Brazilian Cerrado, and Brazilian caatinga, I am interested in the historical determinants of geographic patterns of reptile species diversity in South America.
3. Because of the rapid loss of all major habitats of the world over the past two decades, I am involved in numerous conservation biology projects. These range from advisory roles in conjunction with the US Fish and Wildlife Service to direct involvement in such projects as the National Academy symposium on disappearing amphibians. I have also been involved in a number of faunal surveys associated with development projects in tropical third world countries of South America.
4. Student research has been done on food availability as a determinant of fat storage and reproductive productivity in lizards, sexual selection in wide foraging lizards, evolution of body size, physiological consequences of herbivory, movement and home range ecology of rattlesnakes, performance physiology in an ecological context and biogeography of South American lizards. Student research has appeared in Ecological Monographs, Oecologia, Herpetologica, J. Herpetology, Canadian J. Biology, Copeia, Ecology, etc.
