Evolutionary history of Austropotamobius torrentium

Austropotamobius torrentium is a freshwater crayfish species distributed across central and south-eastern Europe, with the highest genetic diversity recorded in the northern-central Dinarides. Previous studies have shown that evolutionary history of A. torrentium was shaped through different paleohydrologic and paleogeologic events from Miocene onwards. In order to connect current genetic structure of A. torrentium with paleogeographic events divergence time estimates were applied on the large-scale mtDNA dataset. Different calibration approaches were applied, including substitution rates, geological events, and for the first time hydrogeological event of the paleo-Danube and paleo-Tisza rivers connection. We presumed that this event could have had a strong influence onto A. torrentium expansion into nowadays areal. Results obtained by different calibrations yielded mostly congruent results and confirmed complex evolutionary history of A. torrentium. Application
