TL;DR: A consistent positive concave-down effect of biodiversity on forest productivity across the world is revealed, showing that a continued biodiversity loss would result in an accelerating decline in forest productivity worldwide.

TL;DR: An intercomparison of 11 ecosystem models applied to data from two forest free-air CO2 enrichment experiments at Duke University and Oak Ridge National Laboratory yields a framework for analysing and interpreting model predictions of transpiration responses to eCO2, and highlights key improvements to these types of models.

TL;DR: FaceBEAT, an iPhone application for remote heart rate measurement, based on this study is developed based on the potential that the reliable heart rate can be measured remotely by the facial video recorded using smartphone camera.

TL;DR: In this paper, the relative contribution of physical and biological drivers on evapotranspiration (ET) in three ecosystems representing two end-members and an intermediate stage of a successional gradient in the southeastern US (SE).

TL;DR: Testing the hypothesis for progressive nitrogen limitation in ecosystems subjected to a step-function increase in atmospheric CO2 found significantly more N was immobilized in tree biomass and in the O horizon under elevated CO2, and ecosystem C-to-N ratios widened more rapidly under elevatedCO2 than ambient CO2 indicating a more rapid rate of C fixation per unit of N, a processes that could delay PNL in this ecosystem.
