Nucella lapillus (Linnaeus, 1758) [WoRMS]; ANE, Europe, Iberian Peninsula [Marine Regions]; Marine
Analysis of 182 mitochondrial COI sequences from the North Atlantic snail Nucella lapillus revealed high degrees of genetic diversity and structure among populations in Spain and Portugal. Comparatively low diversities, a distinct lack of structure or deep phylogenetic divergence in northern Europe and America supports the hypothesis that the Iberian Peninsula might have been a source of recolonisation of northern after Pleistocene glaciation. The complex genetic structure and presumably old lineages in the Iberian populations provides evidence for a long phylogeographic history shaped by evolutionary dynamics, demographic and climatic changes and a variable physical environment.
