Fig. 6: Relationships between evolutionary metrics and depths (cmbsf) of cold seep sediment samples.

a–c Comparison of SNVs/kbp, pN/pS ratio, and D′ against sediment depths at the whole-genome level. d–f Comparison of SNVs/kbp, pN/pS ratio, and major allele frequency against sediment depths at the gene level. Each dot represents one species-level microbial population. Linear regressions and R2 values are indicated for different taxonomic groups. Only the significant correlations (P < 0.1) between evolutionary metrics and depth of microbial genomes and genes are shown. The shape of the point indicates the cold seep sites. Detailed taxonomic information for analyzed MAGs and statistics for linear regressions are provided in Supplementary Data 5 and 9, respectively.
