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.

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

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

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...

Abstract. Climate change impacts forest functioning and dynamics, but large uncertainties remain regarding the interactions between species composition, demographic processes and environmental drivers...

Temperatures above a critical threshold can increase leaf minimum conductance after cooling, evidencing a “thermal leaky legacy effect” that can reduce pla
