Stomatal responses of tree species from the cloud forest in central Veracruz, México

open access: yesBotan‪ical Sciences, 2016
Stomatal conductance is considered as a key plant response because it plays an important role in plant physiology by controlling transpiration (water status) and CO2 assimilation, regulating plant productivity.

Predicting photosynthesis and transpiration responses to ozone: decoupling modeled photosynthesis and stomatal conductance [PDF]

open access: yesBiogeosciences, 2012
Plants exchange greenhouse gases carbon dioxide and water with the atmosphere through the processes of photosynthesis and transpiration, making them essential in climate regulation.

The role of abscisic acid and water relations in drought responses of subterranean clover [PDF]

open access: yes, 1997
The role of water relations and abscisic acid (ABA) in the responses to drought were studied in a mediterranean forage crop, Trifolium subterraneum L. under field conditions.

Stomatal control of leaf fluxes of carbonyl sulfide and CO2 in a Typha freshwater marsh [PDF]

open access: yes, 2017
Carbonyl sulfide (COS) is an emerging tracer to constrain land photosynthesis at canopy to global scales, because leaf COS and CO2 uptake processes are linked through stomatal diffusion.

Hydrogen sulphide regulates inward-rectifying K+ channels in conjunction with stomatal closure [PDF]

open access: yes, 2015
Hydrogen sulphide (H2S) is the third biological gasotransmitter and, in animals, affects many physiological processes by modulating ion channels. H2S has been reported to protect plants from oxidative stress in diverse physiological responses. H2S closes

Stomatal conductance limited the CO2 response of grassland in the last century

open access: yesBMC Biology, 2021
Background The anthropogenic increase of atmospheric CO2 concentration (c a) is impacting carbon (C), water, and nitrogen (N) cycles in grassland and other terrestrial biomes.

Relating Stomatal Conductance to Leaf Functional Traits [PDF]

open access: yesJournal of Visualized Experiments, 2015
Leaf functional traits are important because they reflect physiological functions, such as transpiration and carbon assimilation. In particular, morphological leaf traits have the potential to summarize plants strategies in terms of water use efficiency, growth pattern and nutrient use.

Physiological drought responses improve predictions of live fuel moisture dynamics in a Mediterranean forest. [PDF]

open access: yes, 2018
The moisture content of live fuels is an important determinant of forest flammability. Current approaches for modelling live fuel moisture content typically focus on the use of drought indices.

Morphoanatomical Responses and Stomatal Conductance in Shaded and Sun-Exposed Broussonetia papyrifera Seedlings

open access: yesJurnal Sylva Lestari, 2023
Investigating invasive species’ morphoanatomical characteristics, such as leaf area and thickness of vascular tissues and storage cells, can reveal information about their adaptive ability and competitive advantage.

Radiometric Method for Determining Canopy Stomatal Conductance in Controlled Environments

open access: yesAgronomy, 2019
Canopy stomatal conductance is a key physiological factor controlling transpiration from plant canopies, but it is extremely difficult to determine in field environments.
