Map showing the sampling sites (red dots) of for <i>Coryphaenoides mediterraneus</i>.

<p>Pie charts report the haplotype distributions of the mtDNA COI, with the proportion of each haplotype within each collection site. Each haplotype is colour coded according to the legend on the right. Abbreviations of the collection sites are given in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0174988#pone.0174988.t001" target="_blank">Table 1</a>. Dark and dashed lines represent the potential barriers to gene flow: CGFZ—Charlie-Gibbs fraction zone; SG—Strait of Gibraltar; AOF- Almeria-Oran front; SS—Strait of Sicily; SM—Strait of Messina.
