Comment : The objectives of this paper were to study the spatial and temporal variation in soil respiration in a temperate forested landscape and to evaluate temperature and soil water functions as predictors of soil respiration. Occurrence of high Q10 values and variation in Q10 may be related to: (1) confounding effects of high soil water content: (2) seasonal and diel patterns in root respiration and turnover of fine roots that are linked to above ground phenology and metabolism: and (3) variation in the depth where CO2 is produced. The Q10 function can yield reasonably good predictions of annual fluxes of CO2, but it is a simplification that masks responses of root and microbial processes to variation in temperature and water content throughout the soil.
