The role of stomata in sensing and driving environmental change.
TL;DR: Stomatal morphology, distribution and behaviour respond to a spectrum of signals, from intracellular signalling to global climatic change, which results from a web of control systems reminiscent of a ‘scale-free’ network, whose untangling requires integrated approaches beyond those currently used.

Development of a global evapotranspiration algorithm based on MODIS and global meteorology data
TL;DR: In this article, the authors developed a global remote sensing evapotranspiration (ET) algorithm based on Cleugh et al.'s [Cleugh, H.A., R. Leuning, Q. Mu, S.W. Running (2007) Regional evaporation estimates from flux tower and MODIS satellite data.

TL;DR: The results of this study indicate that the current MODIS GPP algorithm shows reasonable spatial patterns and temporal variability across a diverse range of biomes and climate regimes.

How plant functional-type, weather, seasonal drought, and soil physical properties alter water and energy fluxes of an oak-grass savanna and an annual grassland
TL;DR: In this article, the authors examine how a number of abiotic, biotic and edaphic factors modulate water and energy flux densities over an oak-grass savanna and an annual grassland that coexist in the same climate but on soils with different hydraulic properties.

Seasonal and interannual variation in carbon dioxide exchange and carbon balance in a northern temperate grassland
TL;DR: In this article, the authors measured the net ecosystem carbon dioxide exchange (NEE) in a northern temperate grassland near Lethbridge, Alberta, Canada for three growing seasons using the eddy covariance technique.

TL;DR: In this article, the large-scale parameterization of the surface fluxes of sensible and latent heat is properly expressed in terms of energetic considerations over land while formulas of the bulk aerodynamic type are most suitahle over the sea.

An Introduction to Environmental Biophysics
TL;DR: The Light Environment of Plant Canopies Appendix as discussed by the authors describes the light environment of plant canopies in terms of temperature, wind, and water flow in the soil and water vapor and other gases.

The Interpretation of the Variations in Leaf Water Potential and Stomatal Conductance Found in Canopies in the Field
TL;DR: In this paper, the stomatal conductance of illuminated leaves is a function of current levels of temperature, vapour pressure deficit, leaf water potential (really turgor pressure) and ambient CO $_2$ concentration and when plotted against any one of these variables a scatter diagram results.

Physiological and environmental regulation of stomatal conductance, photosynthesis and transpiration: a model that includes a laminar boundary layer
TL;DR: In this article, a system of models for the simulation of gas and energy exchange of a leaf of a C3 plant in free air is presented, where the physiological processes are simulated by sub-models that: (a) give net photosynthesis (An) as a function of environmental and leaf parameters and stomatal conductance (gs); (b) give g, as well as the concentration of CO2 and H2O in air at the leaf surface and the current rate of photosynthesis of the leaf.
