Soil CO2 Fluxes in Spruce Forests — Temporal and Spatial Variation, and Environmental Controls
The predicted changes to the climate in temperate zones (IPCC 2001) are prone to alter physiological processes of both carbon sequestration and carbon release of terrestrial ecosystems. Whether temperate ecosystems will act as sources or sinks of carbon under altered environmental conditions depends on the way in which the balance of these processes is shifted in the short term, and in the long term. Soils of forest ecosystems are generally regarded as crucial to this balance since real long-term storage of carbon occurs only in the soil (Goodale et al. 2002). In temperate forest ecosystems, over 60 % of carbon stocks are in the soil (IPCC 2000), and changes in climate, as well as in land use, are likely to alter the input to and release from soils, thus changing their potential for C storage.
