Abstract

Recent studies revealed convergent temperature sensitivity of ecosystem respiration (R_e) within aquatic ecosystems and between terrestrial and aquatic ecosystems. We do not know yet whether various terrestrial ecosystems have consistent or divergent temperature sensitivity. Here, we synthesized 163 eddy covariance flux sites across the world and examined the global variation of the apparent activation energy (Ea), which characterizes the apparent temperature sensitivity of and its interannual variability (IAV) as well as their controlling factors.

Keywords

activation energy, ecosystem respiration, index of water availability, interannual variability, gross primary productivity
