Climate change may enhance or diminish ecosystem productivity, depending on environmental factors such as nitrogen or water availability. CO2 enrichment initially enhances productivity, but over time (days to years) this enhancement declines, a phenomenon called CO2 acclimation. One possible cause of CO2 acclimation is progressive nitrogen limitation.
Aspen are growing under different CO2 atmospheres in the free air CO2 enrichment (FACE) site in Rheinlander, WI.
