Disentangling atmospheric and soil drought: a new stand‐level manipulation approach for mature forests

Summary Atmospheric and soil drought are major, yet typically confounded, drivers of tree stress. Rising vapor pressure deficit (VPD) may impair forest function independently of soil moisture decline, yet stand‐scale experimental separation in mature forests has remained unresolv...

Canopy‐scale VPD reduction in a mature forest alters stomatal response to soil drought in Pinus sylvestris L.

Summary Understanding how trees respond to interacting soil and atmospheric droughts is crucial for predicting forest resilience under climate change. However, no experiment has yet jointly manipulated vapor pressure deficit (VPD) and soil moisture in forests, limiting our abilit...
