highly significantp < 0.001
Comparing different samples (LDU, MJS, and XLS) in the bacterial communities, only the richness was highly significant with the location effect ( F = 283.34, p < 0.001; Table S3 ), the host tree effect ( F = 10.79, p < 0.001; Table S3 ), and the interaction effect of the location and host tree ( F = 3.97, p = 0.003; Table S3 ), respectively, whereas for the fungal communities, the richness, the evenness, and the diversity were all significant with these factors at different degrees ( Table S3 ).
