TL;DR: For 212 days, including a 117-day-long summer drought with only 45mm rainfall, fluxes of latent and sensible heat (λE and H, respectively) and carbon dioxide (CO2) were measured by eddy covariance over a tussock grassland in New Zealand as discussed by the authors.

TL;DR: In the water-limited environment, variation in C sequestration rate was largely accounted for by a parameter integrative for changes in soil water content and the combination of mensurational data with canopy and ecosystem C fluxes yielded an estimate of heterotrophic respiration approximately 30% of NPP' and approximately 50% ofNEP.

TL;DR: It is suggested that the observed responses occurred because of a perturbation to the hydraulic pathway in the xylem that could have triggered the action of a chemical signal to regulate stomatal conductance and photosynthesis.

TL;DR: In this paper, the three dimensional distribution of intercepted radiation, intercellular CO2 concentration (Ci) and late summer needle nitrogen (N) concentration were determined at the tips of all 54 branches in a 6·2m-tall Pinus radiata D. Don tree growing in a New Zealand plantation.

TL;DR: In this article, total and forest floor carbon dioxide flux densities (FCO2) and environmental variables were measured for 18 consecutive mid-summer days during July 1996 in a 215-year-old stand of Pinus sylvestris L. trees located 40 km southwest of the village of Zotino in central Siberia, Russia (61°N, 89°E, 160m asl).
