Changes in temperature and precipitation extremes are enhancing severe droughts, mortaility of forests and woodlands, and increasing pressure on water resources for growing food. We seek mechanistic understanding of these dynamics by looking through the lens of plant hydraulics, which describes water flow from the soil to the atmosphere through plant xylem, and is a vital pathway for nutrient, carbon, and energy exchanges. We have recently turned to genomics to help refine our mechanistic understanding of plant responses to environmental change. Our approach is to combine empiricism, mathematical models, and data analytics. One product of our research is the Terrestrial Regional Ecosystem Exchange Simulator (TREES), a biophysical model of plant hydraulics, carbon and nitrogen dynamics, and hydrology.
