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 …

Recent observations of elevated tree mortality following climate extremes, like heat and
drought, raise concerns about climate change risks to global forest health. We currently lack …

An exponential rise in the atmospheric vapour pressure deficit (VPD) is among the most
consequential impacts of climate change in terrestrial ecosystems. Rising VPD has negative …

Both low soil water content (SWC) and high atmospheric dryness (vapor pressure deficit,
VPD) can negatively affect terrestrial gross primary production (GPP). The sensitivity of GPP …

Ecosystems are dynamic systems with complex responses to environmental variation. In
response to pervasive stressors of changing climate and disturbance regimes, many …

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

Plant water stress occurs at the point when soil moisture (SM) limits transpiration, defining a
critical SM threshold (θcrit). Knowledge of the spatial distribution of θcrit is crucial for future …

Silicon is absorbed as uncharged mono-silicic acid by plant roots through passive
absorption of Lsi1, an influx transporter belonging to the aquaporin protein family. Lsi2 then …

Plant growth is usually constrained by the availability of nutrients, water, or temperature,
rather than photosynthetic carbon (C) fixation. Under these conditions leaf growth is …

Widespread tree mortality associated with drought has been observed on all forested
continents and global change is expected to exacerbate vegetation vulnerability. Forest …
