Figure 2

(a) Composition of Symbiodiniaceae communities within coral microbiomes in the Abrolhos Bank: the host species are discriminated at the top of the plot, and the four reef sites are indicated at the bottom. (b) Richness and Shannon index; letters and symbols (*) indicate significant Wilcoxon’s pairwise comparisons test (p < 0.05 after BH correction). Tests and boxplot size were calculated without ESQ samples however their values were indicated in plots by dots. (c) Nonmetric multidimensional scaling (nMDS) plots calculated according to Bray–Curtis distance on the square root of the relative ITS2 type abundances. The stress of each nMDS is indicated in the figures. Colors correspond to host species taxa (FAGR Favia gravida, MOCA Montastraea cavernosa, MUBR Mussismilia braziliensis, MUHA Mussismilia harttii) and symbols to reef sites (SG Sebastião Gomes, PAB Parcel dos Abrolhos, TIM Timbebas, ESQ Esquecidos Reef).
