Soil and microbial variables simulated by MEND. Warming, in situ warmed soils; Control, unwarmed/control soils. a Simulated and observed soil respiration rates during the 975-day laboratory incubation period, showing high consistency. b Simulated soil heterotrophic respiration rates over 10 years. c Simulated soil organic C over 10 years. d Simulated active microbial biomass C over 10 years. e Simulated decomposition rates of oxidative enzymes over 10 years. The Kruskal-Wallis test was used to determine whether the parameter samples originated from significantly different distribution at a significance level of 0.05
