Principal coordinate analysis (PCoA) of the distal intestinal microbiota using UniFrac distances. The percentage of variation is explained by PC1 and PC2 axis. Each plot represents the differences between control (blue circles) and probiotic (red triangles) groups in both stages freshwater (FW) and seawater (SW). (A) PCoA weighted UniFrac digesta; (B) PCoA unweighted UniFrac digesta; (C) PCoA weighted UniFrac mucosa; (D) PCoA unweighted UniFrac mucosa.
