Mechanisms of Environmental Stress Tolerance
My interest in understanding the fundamental physiological mechanisms that allow aquatic species to respond to environmental stress began when I was an undergraduate student and has continued to present. We have ongoing projects that vary in research breadth and scope and include investigations in thermal and hypoxic physiology and behavior of fishes, seasonal variation in thermal tolerance, comparative thermal physiology of eurythermal and stenothermal batoid species, and mechanisms of thermal acclimation and adaptation in killifish. Thermal tolerance variation is of particular interest and has been a focus of study for some time, yet the fundamental mechanisms that determine thermal tolerance limits and an organism’s thermal niche are not yet well understood. These projects take us to rockpools in the Carribbean, tidepools along the west coast and salt marshes on the east coast of North America, and to coral reef fish nursery grounds in Indonesia.
