The Mantel statistic R and the significance levels (p) are presented. Significant negative Mantel’s r values indicate decrease of similarity between any two sites as the distance between them increases. Bray–Curtis similarity matrices were calculated using rarefied ASVs tables, log-transformed, and plotted against the geographical distance.
