Fig. 4

Difference in soil CO2 efflux (R S) between the control and warmed plots (bars) and the response ratio (%, points) of R S to warming between the control and warmed plots from June 2011 to April 2012 at the Q. variabilis (black) and P. densiflora (gray) plots. Values represent the mean ± 1 SE (n = 4). Results from a two-way ANOVA factoring in species and months are reported in the figure. Asterisks denote significant differences (*P < 0.05, ***P < 0.001)
