Hydraulic failure resulting from drought‐induced embolism in the xylem of plants is a key
determinant of reduced productivity and mortality. Methods to assess this vulnerability are …

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 …

Global warming is expected to dramatically accelerate forest mortality as temperature and
drought intensity increase. Predicting the magnitude of this impact urgently requires an …

Maintaining water transport in the xylem is critical for vascular plants to grow and survive.
The drought-induced accumulation of embolism, when gas enters xylem conduits, causes …

Cavitation resistance has often been viewed as a relatively static trait, especially for stems of
forest trees. Meanwhile, other hydraulic traits, such as turgor loss point (Ψtlp) and xylem …

Nonstructural carbohydrates (NSCs) have been suggested to affect xylem transport under
fluctuating water availability, but conclusive evidence is still lacking. We tested the effect of …

Damage to the plant water transport system through xylem cavitation is known to be a driver
of plant death in drought conditions. However, a lack of techniques to continuously monitor …

Heatwaves are particularly harmful for plants in combination with drought. The direct effects
of high temperatures by themselves can be severe and their negative impacts depend on …

The mechanisms by which woody plants recover xylem hydraulic capacity after drought
stress are not well understood, particularly with regard to the role of embolism refilling. We …

Xylem cavitation during drought is proposed as a major driver of canopy collapse, but the
mechanistic link between hydraulic failure and leaf damage in trees is still uncertain. Here …
