Many operational taxonomic units (OTUs) display a local phylogenetic signal in specific host clades after accounting for diet. a The phylogeny is the same as shown in Fig. 1. The heatmap depicts local indicator of phylogenetic association (LIPA) values for each OTU–host association, with higher values indicating a stronger phylogenetic signal of OTU presence (with diet regressed-out). White boxes in the heatmap indicate non-significant LIPA indices. The dendrogram on the top of the heatmap is a cladogram based on the SILVA-derived taxonomy for each OTU (see Supplementary Fig. 18 for the full taxonomy). The dendrogram is colored by phylum. The bar plots in b and c show the number of OTUs with a significant LIPA index per host (OTUs are colored by phylum; the number of OTUs per host ranges from 1 to 34). b The bar plots summarize the number of significant OTUs per host order and diet. The bar plots in c are the same as b except the data are grouped by OTU phylum. Source data are provided as a Source Data file
