Stomatal Decoupling From Photosynthesis Under High Temperatures Is Consistent With Stomatal Optimisation

open access: yesGlobal Change Biology, Volume 32, Issue 7, July 2026.
Many leaf gas exchange models predict that photosynthesis and stomatal conductance are tightly coupled and respond in parallel to changing environmental conditions. However, experiments show that when temperatures increase beyond the thermal optimum of photosynthesis, stomatal conductance may continue to rise while photosynthesis declines, facilitating
