TL;DR: Evidence is presented that estimates of increases in carbon sequestration of forests, which is expected to partially compensate for increasing CO2 in the atmosphere, are unduly optimistic and that fertility can restrain the response of woodcarbon sequestration to increased atmospheric CO2.

TL;DR: In this paper, the authors analyzed data from a variety of sources employing both porometric and sap flux estimates of stomatal conductance (gs) to evaluate the hypothesis that stomata sensitivity is proportional to the magnitude of gs at low D (£ 1k Pa).

TL;DR: Analysis of hydraulic constraints imposed on water uptake from soils of different porosities in loblolly pine by comparing genetically related and even-aged plantations growing in loam versus sand soil suggests considerable phenotypic plasticity in water use traits for P. taeda which are adaptive to differences in soil porosity.

TL;DR: In this article, mean canopy stomatal conductance of individual tree crowns (G Si ) was estimated using sap flux measurements in Fagus sylvatica L., and the hypothesis that G Si decreases with tree height was tested.

TL;DR: In this article, the free air CO2 enrichment (FACE) facility (n = 3) in a 14m tall Pinus taeda L. stand was designed to reduce uncertainties in predicting such responses, and continuous measurements of precipitation, throughfall precipitation, sap flux, and soil moisture were made over 3.5 years under ambient CO2a and elevated CO2e conditions.
