Dr. John Sperry, Department of Biology, University of Utah, speaks on the importance of maintaining vascular function to plants. His laboratory investigates hydro-vascular structure and function in plants in relation to their ecology, physiology, and evolution. A mechanistic understanding of the largely physical constraints of xylem transport flow and its failure by cavitation provides insights into metabolic scaling theory, vascular evolution, adaptation to water and freezing stress, and the prediction of plant responses to a changing environment.
