Why do some plants open their stomata at high temperatures? Our new paper shows that this behaviour is optimal, and a crucial thermoregulation strategy. 🍃 However, this only emerges when the leaf energy balance is fully integrated in the optimisation. This is missing from global models at present!

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

Examining the potential thermal sensitivity of the model parameter g1 when accounting for the additive nature of underlying components, including CO2 compensation point and the marginal water cost of plant carbon gain.

Congrats @kalimiddleby.bsky.social on this exciting paper showing local adaptation to warm temperatures in some tropical trees - and to coauthors @drrebeccajordan.bsky.social @martinbreed.bsky.social @awcheesman.bsky.social @mrossettorecer.bsky.social @dcrayn.bsky.social dx.doi.org/10.1111/gcb....

Local Adaptation Drives Leaf Thermoregulation in Tropical Rainforest Trees
We tested whether tropical rainforest trees adjust their leaf traits and resulting leaf temperatures across their distributions within the Australian Wet Tropics. Using field measurements from across...

Preprint with @lucascernusak.bsky.social, @florianabusch.bsky.social and Graham Farquhar! We show that mesophyll cell water status is the key signal regulating non-stomatal control of transpiration. We introduce a mechanistic model linking plant hydraulics and gas exchange. doi.org/10.1101/2025...
