Dr. Pallardy's research interests include the physiological responses of plants to water stress and comparative water relations. Comparative studies are designed to identify several of the mechanisms by which woody species and ecotypes are able to resist drought stress more effectively than others. These interests are scaled to the ecosystem level in studies of plant and environmental controls on forest water and carbon fluxes by eddy covariance and micrometeorological methods.
