Estimates of beta diversity from 16S rRNA gene microbiome communities across coral species. A Relative abundances of microbial classes averaged for each coral species. Note that only microbial classes representing > 1% of all reads were included for visualization. Principal coordinates of coral samples colored by coral life history traits based on 16S rRNA gene microbial composition for B ecological life history characteristics, C morphology, D phylogenetic clade, E spawning mode, and F reproductive strategy. Significance testing was based on nested PERMANOVA analyses to account for variation due to coral species, which was highly significant (Table 1). Seawater samples are shown in black and sampling location is denoted by shape
