Phylogeographic patterns of decapod crustaceans at the Atlantic–Mediterranean transition

摘要: Comparative multispecies studies allow contrasting the effect of past and present oceanographic processes on phylogeographic patterns. In study, a fragment COI gene was analyzed in seven decapod crustacean species from five families with different bathymetric distributions. A total 769 individuals were sampled along Atlantic–Mediterranean transition area order to test three putative barriers flow: Strait Gibraltar, Almeria–Oran Front Ibiza Channel. significant Gibraltar found crabs Liocarcinus depurator Macropipus tuberculatus. The Channel had for L. depurator. However, front not have any studied species. Higher levels population structure shallow-water species, although number should be increased obtain conclusive pattern. haplotypes within coalesced at times that could related climatic events occurring before, during after last glacial maximum. Given large diversity patterns obtained decapods, it is concluded both historical contemporary (marine current patterns, bathymetry life-history traits) shape these crustaceans.
