Abstract
As surface temperatures rise\, periodic droughts are more often associated with elevated air temperature s leading to a novel type of “atmospheric drought”. Heat exacerbates d rought conditions during hot droughts because of increased atmospheric dem and for water (i.e.\, vapor pressure deficit\, VPD)\, resulting in conside rable physiological alterations in plants. Recently\, hotter droughts have been associated with large-scale tree die-back\, reduced forest productiv ity\, and increased wildfire incidence. However\, the physiological respon ses of trees to heat and drought driving carbon\, water\, and nutrient exc hange at multiple time scales are not resolved. While much of our attentio n has been directed towards forest responses to soil drought acting in iso lation\, the independent role of high temperature and VPD and the compound impacts of heat and lack of precipitation remain poorly explored. In the Plant Ecology Research Laboratory PERL\, we aim to understand the processe s driving forest responses to drought exacerbation with global warming. Th rough a combination of experimental\, observational\, and modeling approac hes at multiple temporal and spatial scales\, we assess how heat and droug ht alter the physiological functions of trees and forests as a whole. In t his presentation\, I will illustrate how PERL contributes to this general goal by shielding light on the mechanisms driving forest vulnerability to climate change.

About the speaker
How does global warming affect trees – and thus the essential functions and servi ces provided for humans by forests? Charlotte Grossiord\, a plant physiolo gist\, specializing in the carbon and hydraulic functioning of trees\, has been investigating this question throughout her entire scientific career. She received her Ph.D. in 2015 from INRAE and the University of Lorraine (France)\, where she examined the functional significance of forest biodiv ersity in the context of global warming. From 2015-2018\, Charlotte Grossi ord was a Director’s fellow at the Los Alamos National Laboratory (LANL\ , USA)\, where she investigated how forests respond to the worsening of dr oughts with higher temperatures and its feedback to the global carbon and water cycle.
