The significances are tested based on 10 000 permutations. ***P<0.001; **P<0.01; *P<0.05. For the HX group, both the geographic and environmental distances were not significantly related to bacterial phylogenetic turnover (P>0.05). For ZJ and NJ groups, the Mantel analyses are not conducted because of their lower sample numbers (7 and 5, respectively).
