PERMANOVA results, showing the effect size (R²) and P value of factors putatively contributing to the variance among sampled microbiota, using Jaccard (reflecting presence–absence of taxa) and Aitchison (reflecting relative abundance of taxa) distances. Pairwise PERMANOVA between subspecies shows the effect size (R²) and P values adjusted for false discovery rate. P values below 0.05 are shown in bold.
