A Weighted UniFrac (represents phylogenetic distance or amount of branch length not shared by two samples, weighted by the abundance of each sequence variant), distances were driven by phylogenetically dissimilar, abundant groups; B Unweighted UniFrac, distances were driven by phylogenetically dissimilar, less abundant groups; C Bray Curtis (represents dissimilarities driven by differences in abundant species, regardless of phylogeny); D Jaccard distances (driven by differences in less abundant species, regardless of phylogeny)
