Tree drought stress and mortality: the interplay of climate, physiology, hydrology, and lithology

Session ID#: 82975

Session Description:
Drought can have profound impacts on ecosystems and, consequently, their ability to take up carbon. Plants employ a range of strategies, including both above- and below- ground processes, to mediate water stress in order to survive drought. However, mortality is not solely determined by the severity of drought and the efficacy of plants’ physiological strategies to tolerate water stress, but also by the availability of deep soil moisture, which in turn is related to groundwater and bedrock characteristics. How these factors interact to affect the mechanism of drought-induced tree mortality and how tree loss in turn affects climate, carbon uptake, lithology, and hydrology is not yet explained. This session seeks to highlight advances in understanding of this topic. We invite presentations on research at global, regional, and local scales using experiments, field measurements, remote sensing observations (e.g. vegetation greenness, SIF, and water content), or models.
