The accumulated CO2 flux and the priming effect during the 6-day incubation trial. Red lines/symbols represent in situ warmed soils (W) and blue lines/symbols represent unwarmed/control soils (C). Solid lines represent total CO2 and dashed lines represent 13C-CO2. The significance of the difference was determined by one-way ANOVA (n = 3, biological replicates of warmed or control samples) on CO2 amounts and primed C amounts between warmed and control samples (shown in the inset of the figure). W, warmed samples; C, control samples; NS, not significant. Data are shown as mean ± standard error
