Specific Interests

Research in the NET lab (Nutritional, Energetic, and Temperature physiology) investigates how animals respond to resource limitations. Given climatic predictions regarding precipitation patterns in many parts of the globe, our current focus is primarily on water limitations. We examine how water balance affects physiological functions such as immunocompetence, reproduction, and metabolism, as well as how animals mitigate potential negative effects. We use multiple levels of biological organization (communities, organisms, systems, cellular and molecular mechanisms) and a combination of field studies and manipulative laboratory experiments to understand the physiological implications of and adaptive responses to water limitation. By understanding how animals tolerate current instances of limited resource ability, we will be better able to predict how species will be impacted by future climate change and the variability in vulnerability among taxa.
