Discrepancies in phylogeographical patterns of two European anglerfishes (Lophius budegassa and Lophius piscatorius)
چکیده انگلیسی

In order to investigate the relative importance of historical processes and life-history traits in shaping the present-day genetic structure of European anglerfishes, 382 Lophius piscatorius and 134 Lophius budegassa were sequenced on the 5’ end of the mitochondrial control region. Both species showed a limited genetic structure and some evidence of a demographic expansion that probably occurred not at the end of the Last Glacial Maximum, but earlier in the Pleistocene. The main discrepancy between the two anglerfishes concerned the genetic structure between Atlantic and Mediterranean populations, with weak but significant differentiation observed only in L. budegassa. This genetic structure was congruent with the existence of a phylogeographical break previously reported in several marine species across the Almeria–Oran front. The contrast observed between both anglerfishes was supposed to be induced by a possible more ancient (re)colonisation of the Mediterranean Sea by L. budegassa. Finally, the limited genetic structure and lack of isolation by distance observed in both species suggested high larval dispersal capacities that probably overwhelm the influence of the bathymetric distribution range on migrations of adults and juveniles.
