Free-air CO2 enrichment (FACE) experiments have provided novel insights into the ecological mechanisms controlling the cycling and storage of carbon in terrestrial ecosystems and contribute to our ability to project how ecosystems respond to increasing CO2 in the Earth’s atmosphere. Important lessons emerge by evaluating a set of hypotheses that initially guided the design and longevity of forested FACE experiments. Net primary productivity is increased by elevated CO2, but the response can…

Forest soil carbon oxidation state and oxidative ratio responses to elevated CO2
The oxidative ratio (OR) of the biosphere is the stoichiometric ratio (O2/CO2) of gas exchange by photosynthesis and respiration—a key parameter in budgeting calculations of the land and ocean carbon
The fate of carbon in a mature forest under carbon dioxide enrichment
The results call into question the predominant thinking that the capacity of forests to act as carbon sinks will be generally enhanced under eCO2, and challenge the efficacy of climate mitigation strategies that rely on CO2 fertilization as a driver of increased carbon sinks in standing forests and afforestation projects.
Elevated carbon dioxide and ozone alter productivity and ecosystem carbon content in northern temperate forests
Overall, these results suggest that elevated CO2 may create a sustained increase in NPP, whereas the long-term effect of elevated O3 on NPP will be smaller than expected.
Increase in forest water-use efficiency as atmospheric carbon dioxide concentrations rise
A substantial increase in water-use efficiency in temperate and boreal forests of the Northern Hemisphere over the past two decades is found, and a partial closure of stomata is suggested to maintain a near-constant concentration of CO2 inside the leaf even under continually increasing atmospheric CO2 levels.
Decreased water limitation under elevated CO2 amplifies potential for forest carbon sinks
A theoretical analysis combining CO2, soil moisture dynamics, and individual-based competition in forests finds that carbon storage has a complex and significant dependence on rainfall amount and timing and the main effect of increasing CO2 in water-limited forests is a decrease in the amount of time trees spend in water limitation.
Storage in terrestrial ecosystems
Informing climate models with rapid chamber measurements of forest carbon uptake
A rapid and cost-effective method to estimate CO2 exchange from intact vegetation patches under varying atmospheric CO2 concentrations is demonstrated, and an alternative mechanism with considerable empirical support - diversion of excess carbon to storage compounds - into an existing earth system model brings the model output into closer agreement with field measurements.
Global change accelerates carbon assimilation by a wetland ecosystem engineer
The primary productivity of coastal wetlands is changing dramatically in response to rising atmospheric carbon dioxide (CO2) concentrations, nitrogen (N) enrichment, and invasions by novel species,


A multiyear synthesis of soil respiration responses to elevated atmospheric CO2 from four forest FACE experiments
The rapidly rising concentration of atmospheric CO2 has the potential to alter forest and global carbon cycles by altering important processes that occur in soil. Forest soils contain the largest and
Net primary productivity of a CO2-enriched deciduous forest and the implications for carbon storage
A central question concerning the response of terrestrial ecosystems to a changing atmosphere is whether increased uptake of carbon in response to increasing at- mospheric carbon dioxide
Forest response to elevated CO2 is conserved across a broad range of productivity.

The surprising consistency of response across diverse sites provides a benchmark to evaluate predictions of ecosystem and global models and allows us to focus on unresolved questions about carbon partitioning and retention, and spatial variation in NPP response caused by availability of other growth limiting resources.
Microbial Community Responses to Atmospheric Carbon Dioxide Enrichment in a Warm-Temperate Forest
Forest productivity depends on nutrient supply, and sustained increases in forest productivity under elevated carbon dioxide (CO2) may ultimately depend on the response of microbial communities to
CO2 enhancement of forest productivity constrained by limited nitrogen availability
Leaf- and stand-level observations provide mechanistic evidence that declining N availability constrained the tree response to elevated CO2; these observations are consistent with stand- level model projections.
Soil carbon sequestration in a pine forest after 9 years of atmospheric CO2 enrichment
The impact of anthropogenic CO2 emissions on climate change may be mitigated in part by C sequestration in terrestrial ecosystems as rising atmospheric CO2 concentrations stimulate primary
No overall stimulation of soil respiration under mature deciduous forest trees after 7 years of CO2 enrichment
The anthropogenic rise in atmospheric CO2 is expected to impact carbon (C) fluxes not only at ecosystem level but also at the global scale by altering C cycle processes in soils. At the Swiss Canopy
CO2 fertilization in temperate FACE experiments not representative of boreal and tropical forests
Results from free‐air CO2 enrichment (FACE) experiments in temperate climates indicate that the response of forest net primary productivity (NPP) to elevated CO2 might be highly conserved across a
What have we learned from 15 years of free-air CO2 enrichment (FACE)? A meta-analytic review of the responses of photosynthesis, canopy properties and plant production to rising CO2.
The results from this review may provide the most plausible estimates of how plants in their native environments and field-grown crops will respond to rising atmospheric [CO(2)]; but even with FACE there are limitations, which are discussed.
