The global terrestrial carbon sink offsets one-third of the world’s fossil fuel emissions, but the strength of this sink is highly sensitive to large-scale extreme events. In 2012, the contiguous… More
A growing literature is reporting on how the terrestrial carbon cycle is experiencing year-to-year variability because of climate anomalies and trends caused by global change. As CO2 concentration records in… More
Wang, J., X. M. Xiao, P. Wagle, S. Y. Ma, D. Baldocchi, A. Carrara, Y. Zhang, J. W. Dong, and Y. W. Qin. 2016. Canopy and climate controls of gross… More
Many ecophysiological and biogeochemical processes respond rapidly to changes in biotic and abiotic conditions, while ecosystem-level responses develop much more slowly (e.g., over months, seasons, years, or decades). To better… More
Terrestrial ecosystems currently offset one-quarter of anthropogenic carbon dioxide (CO2) emissions because of a slight imbalance between global terrestrial photosynthesis and respiration. Understanding what controls these two biological fluxes is… More
Throughout the southern US, past forest management practices have replaced large areas of native forests with loblolly pine plantations and have resulted in changes in forest response to extreme weather… More
Loblolly pine trees (Pinus taeda L.) occupy more than 20% of the forested area in the Southern United States, represent more than 50%of the standing pine volume in this region,… More
With an increasing fraction of the world’s forests being intensively managed for meeting humanity’s need for wood, fiber and ecosystem services, quantitative understanding of the functional changes in these ecosystems… More
Carbonyl sulfide (OCS), the most abundant sulfur gas in the atmosphere, has a summer minimum associated with uptake by vegetation and soils, closely correlated with CO 2 . We report… More
The functioning of Arctic ecosystems is not only critically affected by climate change,but it also has the potential for major positive feedback on climate. There is, however, relatively little information… More
