Comment 

 Soil respiration and soil water content (SWC) were significantly greater (P=0.09 and 0.003, respectively) on north-facing slopes compared to south-facing slopes, while soil temperature was not
significantly different between slopes (P>0.5). At all sites, soil temperature was the primary factor driving temporal variations in soil respiration (r2=0.84–0.96) followed by SWC, which accounted for 30% of soil respiration spatial and temporal variability.

 Their results indicate that the application of standard temperature-based Q10 models to estimate soil respiration rates for larger geographic areas covering different aspects or climatic regimes are not adequate unless other factors, such as SWC and total soil nitrogen, are considered in addition to soil temperature.
