ClaaTU cladogram showing the common prevalent Firmicutes clades among vertebrates. Monophyletic clades at the family level (found in ≥ 50% of individuals per host group) are represented by magenta squares. The taxonomy assignments of these clades, listed in clockwise order in the caption, are associated with branch colors. Lemon squares highlight prevalent nested nodes at the genus level. All prevalent clades shown are conserved across hosts, but their descendants are differentially conserved across host groups, as indicated by pie charts. Collapsed nodes (represented in the triangle aesthetic) correspond to MAGs belonging to the same finer taxonomy level. Oscillospiraceae, Acutalibacteraceae and Lachnospiraceae (ID996) did not comprise vertebrate-shared MAGs with prevalence levels exceeding the predicted threshold (50%)
