Abstract

Mahecha et al . (Reports, 13 August 2010, p. 838) estimated the temperature sensitivity of ecosystem respiration ( Q 10 ) and showed that temperature sensitivity and its site-to-site variability are lower than previously reported. We demonstrate that their Q 10 value of 1.4 is an underestimate if interpreted as the averaged sensitivities of all ecosystem components, because fast temperature fluctuations penetrate poorly into the soil.
