Fig. 2

Relative abundances and phylogenetic relationships of MAGs. a Heatmap representing the log10-transformed relative abundances of MAGs. Abundance values were computed as genome copies per million reads. To avoid the log transformation of zero values, a small constant (i.e., 1e-9) was added to the raw relative abundance of each MAG. Detailed information of the MAG abundance per metagenomic sample can be found in Additional file 2: Supplementary Table S4. Background color indicates the salinity category, while the outer color bar denotes the phylum. b, c Phylogenetic trees of the reconstructed bacterial and archaeal MAGs. The different background and branch colors in the trees represent the salinity categories and phylum taxonomic annotations of the MAGs, respectively. Color codes are the same as in part (a) of the figure. The solid black dots label branches with a bootstrap value greater than 0.95
