Towards understanding stomatal decoupling under extreme heat: integrating stomatal kinetics, leaf light responses, and the role of stomatal versus cuticular conductance

This study investigates stomatal decoupling under extreme heat by comparing two rainforest and two semi-arid tree species, finding that decoupling occurs in some species but not others, linked to transpirational cooling capacity and light conditions.
