Understanding Variation in Tree Hydraulic Processes and Associated Climate Feedbacks

Session ID#: 161036

Session Description:
To accurately simulate vegetation-climate feedbacks, Earth System Models (ESMs) must realistically represent plant water stress responses. Plants vary greatly in their strategies to cope with water limitation, which manifests as substantial variability in both underlying traits and observed drought responses within and among species. This variation is driven partly by antecedent moisture conditions, and partly by the pedo-climatic conditions in which the plants grow. While plant hydraulics frameworks are rapidly being incorporated into ESMs, the data needed to assess and validate these new models are largely lacking or inaccessible.

 This session will cover the current understanding of plant hydraulics and its role in vegetation-climate interactions, and describe new approaches for generating data necessary to benchmark hydraulic model frameworks. We invite submissions from researchers using observational, experimental, and modeling approaches to explore critical feedbacks between plant hydrodynamics strategies and carbon and water exchange.
