Trees are the living foundations on which most terrestrial biodiversity is built. Central to the
success of trees are their woody bodies, which connect their elevated photosynthetic …

Abstract In 2018, Central Europe experienced one of the most severe and long-lasting
summer drought and heat wave ever recorded. Before 2018, the 2003 millennial drought …

High air temperatures increase atmospheric vapor pressure deficit (VPD) and the severity of
drought, threatening forests worldwide. Plants regulate stomata to maximize carbon gain …

Plant functioning and survival in drylands are affected by the combination of high solar
radiation, high temperatures, low relative humidity, and the scarcity of available water. Many …

Anthropogenic activities such as uncontrolled deforestation and increasing greenhouse gas
emissions are responsible for triggering a series of environmental imbalances that affect the …

During drought, trees reduce water loss and hydraulic failure by closing their stomata, which
also limits photosynthesis. Under severe drought stress, other acclimation mechanisms are …

Many plant water use models predict leaves maximize carbon assimilation while minimizing
water loss via transpiration. Alternate scenarios may occur at high temperature, including …

Water-saver and water-spender strategies are successful adaptations allowing plants to
cope with the limitations of hot desert habitats. We investigated whether the efficacy of the …

Catastrophic failure of the water transport pathway in trees is a principal mechanism of
mortality during extreme drought. To be able to predict the probability of mortality at an …
