Figure 1.
Locality distribution for the common goby, Pomatoschistus microps, in the Northeastern Atlantic Ocean and Mediterranean Sea.
Details about localities and samples are in Table S1.
Figure 2.
Maximum-likelihood tree reconstructed from concatenated control region and cytochrome b gene sequences from Pomatoschistus microps.
A. Individual labels are detailed in Table S1. Individuals with • are from an Atlantic locality, whereas individuals with blue * and red star are, respectively, from northern Europe and Mediterranean localities. Numbers at nodes are for ML bootstrap percentages (≥50%). B. Numbers at nodes are for divergence times (Myr) estimated with PAML and based on a geologic calibration point, 6.05±0.09 Myr (between 6.14 and 5.96 Myr) [7]. For both figures, P. microps lineages are indicated on the right.

Figure 3.
Demographic history of Pomatoschistus microps inferred from concatenated control region and cytochrome b gene sequences.
Observed mismatch distributions (grey line) for each lineage are compared to expected distributions (black line) under a population growth-decline model.

Figure 4.
Median-joining network of the concatenated control region and cytochrome b gene haplotypes for Pomatoschistus microps of the Mediterranean lineage.
Haplotypes are indicated by numbers as given in Table S1. Line lengths reflect the number of mutational changes (in brackets when >1) between haplotypes.
Figure 5.
Non-multidimensional scaling plot using pairwise FST values from the four Pomatoschistus microps lineages.
The Mediterranean group integrates all the common gobies of the Mediterranean lineage, while the Atlantic group includes individuals from the Atlantic lineages (A1, A2 and NE).
