Composition of major module microbial species and soil enzyme activity in two ecological niche networks as evaluated by Mantel tests. (A) Mantel test between the taxonomic composition of major modules in the rhizosphere soil ecological network and soil enzyme activities. (B) Mantel test between the taxonomic composition of major modules in the endophytic fungal ecological network and soil enzyme activities. The depth of the red colour represents the Pearson correlation coefficient between soil enzyme activities. The lines indicate the correlation coefficient (R) of the Mantel test between the taxonomic composition of modules and soil enzyme activities, and the thickness of the lines represents the strength of the correlation. Different colours of the lines represent different P-values of the Mantel test. The significance of the correlation between soil enzyme activities is indicated as follows: * P < 0.05, ** P < 0.01, and *** P < 0.001.
