 le:\n"Exploring forest physiology to better address climate change"\n\nAbs
 tract\nAs surface temperatures rise\, periodic droughts are more often ass
 ociated with elevated air temperatures leading to a novel type of “atmos
 pheric drought”. Heat exacerbates drought conditions during hot droughts
  because of increased atmospheric demand for water (i.e.\, vapor pressure 
 deficit\, VPD)\, resulting in considerable physiological alterations in pl
 ants. Recently\, hotter droughts have been associated with large-scale tre
 e die-back\, reduced forest productivity\, and increased wildfire incidenc
 e. However\, the physiological responses of trees to heat and drought driv
 ing carbon\, water\, and nutrient exchange at multiple time scales are not
  resolved. While much of our attention has been directed towards forest re
 sponses to soil drought acting in isolation\, the independent role of high
  temperature and VPD and the compound impacts of heat and lack of precipit
 ation remain poorly explored. In the Plant Ecology Research Laboratory PER
 L\, we aim to understand the processes driving forest responses to drought
  exacerbation with global warming. Through a combination of experimental\,
  observational\, and modeling approaches at multiple temporal and spatial 
 scales\, we assess how heat and drought alter the physiological functions 
 of trees and forests as a whole. In this presentation\, I will illustrate 
 how PERL contributes to this general goal by shielding light on the mechan
 isms driving forest vulnerability to climate change.\n\nAbout the speaker\
 nHow does global warming affect trees – and thus the essential functions
  and services provided for humans by forests? Charlotte Grossiord\, a plan
 t physiologist\, specializing in the carbon and hydraulic functioning of t
 rees\, has been investigating this question throughout her entire scientif
 ic career. She received her Ph.D. in 2015 from INRAE and the University of
  Lorraine (France)\, where she examined the functional significance of for
 est biodiversity in the context of global warming. From 2015-2018\, Charlo
 tte Grossiord was a Director’s fellow at the Los Alamos National Laborat
 ory (LANL\, USA)\, where she investigated how forests respond to the worse
 ning of droughts with higher temperatures and its feedback to the global c
 arbon and water cycle. After obtaining an SNSF Ambizione Career grant\, sh
 e joined the Swiss Federal Institute for Forest\, Snow\, and Landscape Res
 earch WSL (Switzerland) in 2018. In 2020\, EPFL and WSL jointly appointed 
 her tenure-track assistant professor. She is now leading the Plant Ecology
  Research Laboratory PERL.
