Drought-associated woody-plant mortality has been increasing in most regions with multi-
decadal records and is projected to increase in the future, impacting terrestrial climate …

Future increases in drought severity and frequency are predicted to have substantial impacts
on plant function and survival. However, there is considerable uncertainty concerning what …

Heatwaves exert disproportionately strong and sometimes irreversible impacts on forest
ecosystems. These impacts remain poorly understood at the tree and species level and …

Frequent observations of higher mortality in larger trees than in smaller ones during
droughts have sparked an increasing interest in size‐dependent drought‐induced mortality …

European beech (Fagus sylvatica) was among the most affected tree species during the
severe 2018 European drought. It not only suffered from instant physiological stress but also …

Plant hydraulics is crucial for assessing the plants' capacity to extract and transport water
from the soil up to their aerial organs. Along with their capacity to exchange water between …

Eastern Australia was subject to its hottest and driest year on record in 2019. This extreme
drought resulted in massive canopy die‐back in eucalypt forests. The role of hydraulic failure …

Trees remain sufficiently hydrated during drought by closing stomata and reducing canopy
conductance (G c) in response to variations in atmospheric water demand and soil water …

Tree water use is central to plant function and ecosystem fluxes. However, it is still unknown
how organ‐level water‐relations traits are coordinated to determine whole‐tree water‐use …

Hydraulic properties control plant responses to climate and are likely to be under strong
selective pressure, but their macro‐evolutionary history remains poorly characterised. To fill …
