Recent pause in the growth rate of atmospheric CO2 due to enhanced terrestrial carbon uptake
Terrestrial ecosystems play a significant role in the global carbon cycle and offset a large fraction of anthropogenic CO2 emissions. The terrestrial carbon sink is increasing, yet the mechanismsExpand

Towards a universal model for carbon dioxide uptake by plants
Gross primary production (GPP)—the uptake of carbon dioxide (CO2) by leaves, and its conversion to sugars by photosynthesis—is the basis for life on land. Earth System Models (ESMs) incorporating theExpand

Evidence of a universal scaling relationship for leaf CO2 drawdown along an aridity gradient.
The leaf carbon isotope ratio (δ(13) C) of C3 plants is inversely related to the drawdown of CO2 concentration during photosynthesis, which increases towards drier environments. We aimed toExpand

Nine-year reciprocal transplant experiment in the gardens of the basin and mountain big sagebrush ( Artemisia tridentata : Asteraceae) hybrid zone of Salt Creek Canyon: the importance of
We have studied reciprocal transplant gardens involving the hybrid zone between basin and mountain big sagebrush ( Artemisia tridentata ) in Salt Creek Canyon, Utah, for 9 years. Previously, weExpand

Accurate monitoring of human physical activity levels for medical diagnosis and monitoring using off-the-shelf cellular handsets
Numerous laboratory-based studies have been reported on the use of accelerometry for gait and activity analysis particularly among cohorts of elderly subjects. A drawback of such studies is the useExpand

Assimilation of multiple data sets with the ensemble Kalman filter to improve forecasts of forest carbon dynamics.
The ensemble Kalman filter (EnKF) has been used in weather forecasting to assimilate observations into weather models. In this study, we examine how effectively forecasts of a forest carbon cycle canExpand
