Figure 6

Seasonal variation of (a) soil moisture content, (b) soil temperature, and (c) the 31-day moving average for the warming effect. Raw-Q10 model values were estimated from the annual temperature-response equation of Lloyd and Taylor (Equation 4) using the all measured data without accounting for soil moisture anomalies. Normalized-Q10 model values were estimated from the equation that only included Fc data from times when the soil moisture was within the range of annual average ± 1 SD.
