Fig. 3: Taxonomic diversity of G. edwardsi and P. lutea metagenomes.

Bar plots represent the relative abundance of the 10 most abundant taxonomic classes of A Archaea, B Bacteria, C Microbial eukaryotes, and D viruses in G. edwardsi (Gon) and P. lutea (Por). When annotation did not reach the class level, the highest taxonomic rank annotated was used. Less abundant classes were aggregated to the “Others” category. E Shannon diversity of all taxonomic families found in metagenomes. Significant differences in alpha diversity between species and skeletal compartments are denoted by letters above the boxes (Table S6). F Ordination plots of microbial composition at the family level in G. edwardsi and P. lutea. G Maximum likelihood phylogenetical inference of MAGs recovered from G. edwardsi and P. lutea metagenomes. A set of 92 house-keeping genes [79] were used for the reconstruction. H Relative abundance of MAGs clustered to the phylum level with respect to the total binned fraction. Sections G and H share color coding.
