-
Fine-root production was stimulated by elevated CO2
-
Initial enhancement of net primary productivity was not sustained because of feedbacks through the nitrogen cycle.
-
Stable isotope analysis indicated that N availability declined faster in plots exposed to elevated CO2
- Carbon storage in the soil increased in CO2-enriched plots, including in protected forms.
-
Successional development of the understory community was accelerated in elevated CO2
