After accounting for host phylogeny, diet significantly explained alpha- and beta-diversity components but could only explain the prevalence of two operational taxonomic units (OTUs). The boxplots are distributions of phylogenetic generalized least squares R2 and Adj. p for 100 random subsamples of the datasets (one per species for each subsample). a Both alpha-diversity measures were found to be significant. b Some principal component (PC) analysis PCs were significantly explained by diet (asterisk denotes Adj. p < 0.05). The percentage of variance explained for each unweighted Unifrac PC is 18.1, 6.9, 4.2, 3.6, and 2.1 and each weighted Unifrac PC is 27.2, 10.6, 9.6, 6.4, 6.0, and 5.5. c Only two OTUs were found to be significant. Box centerlines, edges, whiskers, and points signify the median, interquartile range (IQR), 1.5× IQR, and >1.5× IQR, respectively. Source data are provided as a Source Data file
