Environmental and Exercise Physiology; Functional Biodiversity

Our research program investigates common morphological features and physiological limitations of marine and terrestrial animals. Primary areas of study include swimming and running energetics, thermoregulation during exercise, and the plasticity of mammalian skeletal muscle. By examining the functional relationships between animals and their environment, we can begin to understand the ecological significance of a species and the adaptive changes that may be necessary for its survival. This research approach provides a powerful tool that enables our group to predict the responses of animals to novel environmental perturbations and to speculate about the physiology and biomechanics of ancestral forms. For example, the thermal lability of marine mammals indicates the level of vulnerability of individual species to natural (El Niño) and anthropogenic (pollution, over-fishing) events. Current research projects in our laboratory that address this problem include metabolic regulation in swimming and diving dolphins, hunting behavior and physiology of Weddell seals in the Antarctic, and the effects of pregnancy on nutritional status of declining populations of Steller sea lions.

The regulation of oxygen uptake and utilization in the skeletal muscles of exercising mammals is another major research area in our laboratory. In the diving or sprinting mammal, the contracting muscle must operate as a closed system. These animals afford an opportunity to examine the expression of molecular and cellular mechanisms that promote enhanced performance while preventing tissue damage during anoxia or hypoxia.
