Ecosystem Hydraulics: Bridging Plant and Soil Water Status Across Scales
Convener: Jessica GuoECSECS | Co-conveners: Kim Novick, Francesco Giardina, Celia Rodriguez-DominguezECSECS, Mukund Palat RaoECSECS
Ecosystem water status directly impacts key ecophysiological processes such as carbon uptake, transpiration, growth, and mortality. How moisture limitation influences these processes is determined by the water content and water potential in soils and plants, and how physiological traits mediate flows throughout the soil-plant-atmosphere continuum. However, due to the complexity of these interactions and the scarcity of water potential timeseries, the magnitude and timing of water stress impacts on ecosystem function have proven difficult to quantify. As climate change accelerates the constraints of soil and atmospheric drought on ecosystems, we must harmonize our efforts to characterize ecosystem hydraulics and develop frameworks for monitoring and prediction. In this PSInet sponsored session, we broadly explore novel approaches for measuring and modeling plant and soil water status, their interaction with physiological traits, and their impacts on ecosystem function. We encourage submissions that utilize empirical, theoretical, modeling, and/or remote sensing techniques at multiple organizational scales, and particularly welcome studies from understudied ecoclimatic regions.
