Fig. 1 — PCoA plot based on (a) unweighted and (b) weighted UniFrac distance matrices of 16S rRNA gene derived amplicons, and group significance of beta diversity between different diet groups (Adonis) (c). Both the unweighted (a) and weighted (b) UniFrac distance matrices showed clustering according to group (c). The degree of variation among 10 jackknifed replicates of PCoA is showed as confidence ellipsoids around each group
