Functional Phenology of a Texas Post Oak Savanna from a CHRIS PROBA Time Series
Remnant midwestern oak savannas in the USA have been altered by fire suppression and the encroachment of woody evergreen trees and shrubs. The Gus Engeling Wildlife Management Area (GEWMA) near Palestine, Texas represents a relatively intact southern ...

Decomposing reflectance spectra to track gross primary production in a subalpine evergreen forest
. Photosynthesis by terrestrial plants represents the majority of CO2 uptake on Earth, yet it is difficult to measure directly from space. Estimation of gross primary production (GPP) from remote sensing indices represents a primary source of uncertainty,

Rising CO2 drives divergence in water use efficiency of evergreen and deciduous plants
A rapid rise in CO2 has made evergreen trees more waterwise than deciduous trees, especially in cooler parts of the world. Intrinsic water use efficiency (iWUE), defined as the ratio of photosynthesis to stomatal conductance, is a key variable in plant ...
