Phylogeography of the common goby, Pomatoschistus microps , with particular emphasis on the colonization of the Mediterranean and the North Sea
The phylogeographical patterns of a small marine fish, the common goby, Pomatoschistus microps , were assessed at 12 sites along the northeastern Atlantic coasts and the western Mediterranean Sea.

The phylogeographical patterns of a small marine fish, the common goby, Pomatoschistus microps , were assessed at 12 sites along the northeastern Atlantic coasts and the western Mediterranean Sea.

Both markers were congruent in revealing significant differences between samples (global F ST = 0.247 for the allozymes and [ Greek symbol ]Phi F ST = 0.437 for the mitochondrial DNA data) and a pattern of isolation-by-distance. Phylogeographical analyses yielded a shallow branching structure with four groups. Three of those were confined to the Atlantic basin and showed a star-like pattern. The fourth group contained a central haplotype occurring at the edges of the species’ distribution, accompanied by a few more rare variants, which were restricted to the Mediterranean Sea.
