My recent field research has focused on the impact of climate warming on ectotherms in the Luquillo rainforest and the Guanica tropical dry forest in Puerto Rico. Part of this work involves comparisons of the current niche relationships and abundances of resident anoles, as well as arthropod densities, with studies that I conducted in the same locations during the 1970s. Since that time, the average temperature of the rainforst has increased by 2.2 C. To date we have discovered major changes in resource utilization, abundances, and sex ratios of several Puerto Rican anoles, and have documented a 10-20 fold decline in numbers and biomass of arthropod prey. In the area of computational ecology, I collaborate with Professor Peter Kramer from RPI’s Department of Mathematics in developing biology-based models of ecosystem dynamics.
