#wateruseefficiency — Public Fediverse posts

Are smaller stomata faster in reacting to environmental changes such as light, CO2, atmospheric humidity, temperature ? I have participated with our data in a group publication where we take a closer look at the "Speedy small stomata" paradigm.
Using data from over 80 plant species, we found only weak correlations between stomatal size and maximum stomatal closing or opening speeds as well as response times.
Instead, stomatal speed appears to be context-dependent, shaped by species-specific traits, stomatal type and broader anatomical and physiological features.
These findings support a trait-based approach to assessing stomatal kinetics, which has implications for understanding #EcosystemFunctioning under #ClimateChange and #CropBreeding for higher #WaterUseEfficiency and #photosynthesis.

Please BOOST : There is still time (until next Wednesday 18 June) for any interested master student to apply for the doctoral thesis in #Forest #Ecophysiology on the subject of "Defining functional strategies at the whole-plant level by integrating traits related to carbon acquisition and water use in seedlings of Fagaceae" that we offer here in Nancy.
More explicitely, this thesis is about #drought responses of #tree seedlings, considering all organs and many #FunctionalTraits , but somewhat focused on #CarbonAllocation, #WaterUseEfficiency and #PlantHydraulics .
The thesis takes place close to Nancy, East of France, in the #INRAe campus which is at the edge of a very nice forest. The student will work in our very active tree ecophysiology group (PHARE) of the Silva unit. More information can be found on the Silva website :

And don't hesitate to BOOST and share in your networks. Thanks !
