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.
