Five most predominant bacterial phyla and genera comprising at least 1% of all bacteria in the hindgut microbial community of hibernating (n = 5) and active (n = 8) frogs. n.d., not detected. Relative abundance data for all observed taxa are presented in electronic supplementary material, table S2. Bold typeface signifies that relative abundance (%; mean ± s.e.) of the indicated taxon differed (*p < 0.05; **p < 0.01) between groups.
