Figure 3 Structural equation modelling analyses to examine the overall effect on accumulated microbial respiration rate (AccMR_MAT, a) and temperature sensitivity (Q 10, b). The model fit the data well (AccMR_MAT: Fisher’s C=172.98, P=0.00, Df=94, AIC=256.98, BIC=332.86, N=45; Q 10: Fisher’s C=170.27, P=0.00, Df=86, AIC=236.27, BIC=295.89, N=45; AccMR_0_PerSC: Fisher’s C=275.83, P=0.00, Df=126, AIC=367.83, BIC=450.94, N=45;). Solid arrows indicate significant (P < 0.05) positive (black) or negative (red) relationships. Values associated with the arrows represent standardized path coefficients. Widths of significant paths are scaled by standardized path coefficients.
