Phylosymbiosis: Relationships and Functional Effects of Microbial Communities across Host Evolutionary History

Fig 2

Meta-analysis of microbiota variation across five host clades.

(A) PCoA analysis of Bray–Curtis ecological similarity in three dimensions based on 99% operational taxonomic unit (OTU) cutoff, with colors depicting clade of origin. (B) Phylum level relative abundance for all samples, with a key provided in C. (C) Network analysis in which small squares depict samples, with their color indicating clade of origin. Lines connect genus-level OTUs to samples and are weighted by occurrence and colored by OTU phylum. (D) Shannon alpha diversity for each host species. Small ellipses depict individual samples, and dark lines indicate the species’ median diversity. The lower and upper end of each box represent the 25th and 75th quartiles, respectively. Whiskers denote the 1.5 interquartile range. Data available at [26] in folders (A) Fig_2A, (B) Fig_2B, (C) Fig_2C, (D) Fig_2D.
