Fig. 3From: Microbial symbiosis and coevolution of an entire clade of ancient vertebrates: the gut microbiota of sea turtles and its relationship to their phylogenetic historyPrinciple co-ordinate analysis (PCoA) of Bray-Curtis distance showing functional microbial diversity across all species. Significant differences for microbiota composition existed between all species (R2 = 0.29, p = 0.001). For pairwise comparisons between species see Table S4Back to article page
