Loss of Stomatal Regulation Sensitivity to CO2 and Reduced Xylem Hydraulic Conductivity Contribute to Long‐Term Tree Decline and Mortality Increasing drought threatens forests, but tree species respond differently. We examined how long-term drought and rising CO2 affect three Mediterranean tree species with different drought tolerances....

The ability of some trees species to respond to climate and/or CO2 may increase their survival under global change. Species with lower plasticity may face higher mortality. Our new study in @globalchangebio.bsky.social onlinelibrary.wiley.com/doi/10.1111/... #WhatKillsTrees

🌿πŸ”₯How heat and VPD shape tree survival? We tested how acclimation to high temperature & VPD impacts drought mortality. While heat speeds up death via leaf area expansion, VPD acclimation slows it down by enhancing stomatal control - balancing mortality timing. doi.org/10.1111/PCE....

New results from the #BIFoR #FACE experiment. Old-growth oak trees show signs of reduced water usage under elevated CO2, but also strong interannual variability, whilst "ghost" trees use less water than those in other treatments. Full details here: doi.org/10.5194/bg-2...

Detailed representation of H2O gas exchange (left) and CO2 gas exchange (right) at the adaxial (upper) and abaxial (lower) leaf surfaces in an amphistomatous leaf. This panel illustrates the separate gas exchange processes for each leaf surface, which can be measured individually if the upper and lower cuvettes are analysed separatelyβ€”though this setup is not common in commercial gas exchange systems. Stomatal, cuticle, and boundary layer resistances are depicted for both surfaces, along with the mole fractions of water vapour and CO2.
