Summary statistics of nucleotidic polymorphism for mitochondrial and nuclear sequences.

Ba: Bathymodiolus azoricus (Rb: Rainbow; MG: Menez Gwen); Bp_Lg: B. puteoserpentis Logatchev; Bt_7S: B. thermophilus 7°S.N: Number of sequences.L: Average length (bp) of the sequences from each species.S: Number of polymorphic sites.θ: Estimate of 2Nfμ (mtDNA) (Nf is the effective number of females) or 4Neμ (nuclear DNA) per base pair using the number of polymorphic sites [35].π: Estimate of 2Nfμ (mtDNA) or 4Neμ (nuclear DNA) using the average number of nucleotide difference per site [36].Tajima's D: Tajima's statistic [37].R2: Ramos-Onsins and Rozas statistic [38]. Significativity tested by coalescent simulation (given the number of segregating sites and no recombination) (*: pDiv.: Average number of nucleotidic substitutions per site between populations. SAA: Same As Above.Фst: population differentiation, tested by 1000 permutations with the Arlequin software (*: p
