Abstract: We compared the general protein patterns of different populations of the epitokous form of the polychaete Perinereis cultrifera from the English Channel (Normandy and the north coast of Brittany) and the Mediterranean Sea (Algerian coast near the Tunisian boarder) using high resolution two-dimensional gel electrophoresis (2-DGE). Data sets were converted to similarity coefficients using the Dice coefficient, based on more than 150 protein spots. UPGMA dendrogram reveals a clear distinction between the three populations, individuals from the same population clustering together. The genetic distances between populations from the English Channel and the Mediterranean are large compared to those within populations. As a consequence, our results indicate a restricted gene flow between our sampled populations. In addition, the general protein pattern of individuals from the Mediterranean contains 5 exclusive spots whereas no specific spots were detected between the two populations of the English Channel which share one exclusive spot by comparison to the mediterranean form.
