Pressured to transpire: drought, heat and forests

VPD (Vapor Pressure Deficit) is one of the main forces governing plant transpiration. Its recent increase as a consequence of climate change is a matter of concern for forests, even in humid, tropical climates as high VPD might exacerbate forest mortality.
Disentangling the effects of VPD from those of other factors such as heat and drought is a new challenge for scientists worldwide. This is precisely the aim of this high-end project conducted by Prof. Charlotte Grossiord at four sites in Switzerland, capitalizing on the human competences and exceptional research infrastructure of SwissForestLab.
