Fig 7.

Scatterplots depict the relationship between soil functions and OTUs across environmental gradients for three groups. Significant positive or negative trends are highlighted with red regression lines, indicating varying R² and P values across gradients.

Relationships between AT (a), IT (b), and RT (c) α diversity (Chao 1 index) and individual soil function (N = 20). The lines represent the fitted linear ordinary least squares (OLS) model. The red and black lines denote statistically significant (P < 0.05) and nonsignificant (P > 0.05) relationships, respectively. Note: “**” means P < 0.01; “*” means P < 0.05.
