Fig. 4
SEM analysis of bacteria and fungus with environmental factors. a, b represent structural equation model analysis of bacteria and fungi. TOC, AN, VWC, ST represent as above; BC bacterial community, FC fungi community. Solid arrows indicate positive correlations, and dotted arrows indicate negative correlations. Values associated with arrows indicate standardized path coefficients (*p < 0.05; **p < 0.01; ***p < 0.001). Arrow width represents the size of the corresponding normalized path coefficient. Percentage (R2) associated with response variables represent the proportion of contributed to variation by other variables
