Some big news for my lab, and for forests too, I hope! Very excited to join Michigan State in the Plant Resilience Institute, Departments of Forestry and Plant Biology, next fall. Lots of work ahead studying plant #necrodiversity and #WhatKillsTrees with so many new (& continuing) colleagues!

We found that differences in hydraulic function and residual transpiration help determine drought resilience, offering new insights for forest management, breeding, and predicting forest responses to climate change. @hcochard.bsky.social @wmhammond.bsky.social

Sans eau, les forêts arrêtent de capter le Co2 ! @france.theconversation.com theconversation.com/sans-eau-les...

Sans eau, les forêts arrêtent de capter du CO₂

Pour survivre en période de sécheresse, les arbres stoppent la photosynthèse, une activité très gourmande en eau. Des forêts entières se retrouvent ainsi à émettre plus de CO₂ qu’elles n’en capturent.

We are developing a new Forest Water Stress Index (FWSI) based on tree hydraulic functioning. More information: herve.cochard.free.fr/ISF_EN.html

These maps show the current level of water-stress experienced by forests. The first indicator, called the Forest Stress Index (FSI),

How do Cerrado species cope with seasonal droughts? 📝New paper out in @JXBot! We show that hydraulic failure can be minimized through plasticity in water loss, rather than through plasticity in water storage capacity or embolism vulnerability.🌳 👇👇👇 doi.org/10.1093/jxb/...

Hydraulic failure in Cerrado plants is reduced by plasticity in water loss, not water storage or embolism vulnerability

Abstract. Increasingly frequent and intense drought events are challenging the survival of several forest species worldwide. Yet, the extent to which plant

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...

🌿🔥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....
