Study reveals how giant #trees in #tropicalForests transport #water to their uppermost branches
The study published in #Science helps us understand the role of this little-studied type of #vegetation in #climateChange. One percent of the tallest trees store more than half of the #carbon in #tropical forest #ecosystems.

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.

Placing a list of hashtags of interest in your profile keeps them conveniently located for future use, but they won't return your profile to someone else's search using those same terms. If you want people to find you through your common interests, then you will need to place that hashing list inside a post, like so.
