Fifty shades of fade: linking transmittance loss to cellular death during leaf dehydration Drought-induced tree mortality is associated with hydraulic failure and subsequent cell death. Leaf vitality is a critical indicator of tree water stress; however, current methods for assessing ce...

PHOREAU v1.0: a new process-based model to predict forest functioning, from tree ecophysiology to forest dynamics and biogeography Abstract. Climate change impacts forest functioning and dynamics, but large uncertainties remain regarding the interactions between species composition, demographic processes and environmental drivers...

📣So happy to share the PhorEau model, combining models of forest dynamics, plant water relations, and process-based SDM = linking ecophysiology, ecology & biogeography 🌳📈💻

🌿🔥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....

We would need a view from below to see the gills. But Strobilurus tenacellus is a good option I think.

Leaf minimum conductance dynamics during and after heat stress: Implications for plant survival under hotter droughts Temperatures above a critical threshold can increase leaf minimum conductance after cooling, evidencing a “thermal leaky legacy effect” that can reduce pla

🔥Can heatwaves leave a thermal leaky legacy?🔥

Check out our latest paper on gmin dynamics during and after thermal stress🍃📄

Extremely proud of my student Viviane!
