Fields of Interest: Vertebrate ecophysiology. Environmental adaptations.

Research in my laboratory is integrative, and includes studies of ecological and ecophysiological patterns in diverse taxa. Over the years our efforts have contributed to an understanding of phenotypic variation and adjustment to changing environments by small mammals, amphibians, reptiles, and insects. A current focus of interest is in describing the extent of individual variation in reproductive effort, energetic costs and limits, and locomotor performance. This variation is important, as it can influence the extent and rate of natural selection. Previously my graduate students and I have pursued studies of 1) behavioral and physiological plasticity in Anolis lizards, 2) locomotion, metabolism, and reproduction in Eleutherodactylus frogs, 3) constraints during reproduction by small mammals, 4) trade-offs of parasitism and testosterone production in malurid wrens, and 5) costs of flight and terrestrial activity in beetles. The work is germane to an allocation-based life history theory which attempts to relate individual abilities to potential fitness consequences.
