Recent decades have been characterized by increasing temperatures worldwide, resulting
in an exponential climb in vapor pressure deficit (VPD). VPD has been identified as an …

Terrestrial ecosystems are essential for food and water security and CO2 uptake. Ecosystem
function is dependent on the availability of soil moisture, yet it is unclear how climate change …

Dryness stress can limit vegetation growth and is often characterized by low soil moisture
(SM) and high atmospheric water demand (vapor pressure deficit, VPD). However, the …

Tree mortality during global‐change‐type drought is usually attributed to xylem dysfunction,
but as climate change increases the frequency of extreme heat events, it is necessary to …

Stomatal responses to humidity, soil moisture and other factors that influence plant water
status are critical drivers of photosynthesis, productivity, water yield, ecohydrology and …

The timing of diel stem growth of mature forest trees is still largely unknown, as empirical
data with high temporal resolution have not been available so far. Consequently, the effects …

The relationship between stomatal conductance (gs) and leaf water potential (Ψl) is key to
the understanding of plant function under changing climate. The variability among tree …

Via air temperature increases and relative humidity changes, climate change will modify
vapor pressure deficit (VPD), which is an important determinant of water vapor and CO2 …

Plant function requires effective mechanisms to regulate water transport at a variety of
scales. Here, we develop a new theoretical framework describing plant responses to drying …
