An understanding of recent evolutionary processes is essential for the successful conservation and management of contemporary populations. We used a combination of 12 microsatellite markers and cytochrome b sequences on a large dataset across the current range of the European bitterling to investigate possible scenarios for its colonization of Europe. We show that the history of colonization of Europe was largely congruent between mitochondrial and nuclear markers and that genetic diversity was highest in populations from the Pontic region. Much of Europe is currently populated by descendants of two main lineages that came to natural secondary contact in western Europe. An Approximate Bayesian Computation analysis suggests different dates for admixture events among western and central European populations ranging from the last deglaciation (natural) to the last few centuries (human assisted translocations).
