Diversity and similarity of intestinal microbiomes. (a) Relative read abundance of the dominant bacterial classes found within the intestines of each herbivore. For intraspecific variance see electronic supplementary material, figure S1. (b) Microbiome α-diversity. Host species sharing the same letter are not significantly different from each other (Tukey's HSD: p < 0.5). (c) NMDS ordination of compositional similarity (β-diversity) of each microbiome estimated using the Jensen–Shannon divergence index. (Online version in colour.)
