n ≥ 6 host species.
Analyses focused on bacteria from the entire phylogeny or only on those from a subset within the primary army ant clade (see the supplemental material [Fig. S2] for the phylogeny and more details on the analyses).
Sample sizes in parentheses indicate the numbers of bacterial strains falling into each of the compared categories.
Higher UniFrac distances and lower Analysis of Traits D statistics imply greater phylogenetic separation of bacteria from the two focal categories.
Generated using UniFrac's “compare each pair” test.
Analysis of Traits analysis could be performed only on the entire 16S rRNA phylogeny.
NA, not analyzed.
