Influence of soil microbial community on selection gradients (multivariate selection). Soil treatments are complex (autoclave + inoculum) and simple (autoclave). Shown are linear (β) and quadratic (γ) values in each treatment. F‐value from the ANCOVA analysis testing the effect of soil microbe treatment on selection gradients. Degrees of freedom are listed in parentheses after F‐values. Significant effects are indicated with asterisks: *P < 0.05, **P < 0.01, ***P < 0.001.
