PERMANOVA tests were performed on weighted UniFrac distance matrices, which were calculated using bacterial and fungal ASV tables. The results of permutation-based tests of beta-dispersion are displayed (F values), were performed to identify significant differences in the within-group variance of bacterial and fungal communities for each plant-related factor.
