The goal of my research is to
understand various mechanisms that influence the distribution and abundance of
terrestrial vertebrate ectotherms. Specifically, I have been interested in
how environmental variation (temperature and food abundance) interacts with
time budgets and physiological processes of ectotherms to affect their
allocations to growth and reproduction. Thermal effects impinge on the
allocation of energy and resources to the competing functions of maintenance,
growth, reproduction, and storage which in turn, produce variation in
population level processes. My favored approach to these problems is to use
comparative bioenergetics to learn about constraints and trade‑offs that
operate on the physiological performance of individuals. Lately, my interests
have expanded to address proximate and ultimate influences on the evolution of
sexual size dimorphism (also a bioenergetic problem) the use of
individual‑based physiologically structured simulations of growth,
reproduction and population dynamics for predicting the responses of
populations to environmental change, and implications of bioenergetics for
conservation. For our latest Project, check out this YouTube Vid: http://www.youtube.com/watch?v=q-mNOdz_Q3Q
