Event Abstract Back to Event Different histories, different destinies‒impact of evolutionary history and population genetic structure on extinction risk of the Adriatic spined loaches (genus Cobitis; Cypriniformes, Actinopterygii) Ivana Buj1*, Marko Ćaleta2, Zoran Marčić1, Radek Sanda3, Jasna Vukic4 and Milorad Mrakovčić1 1 Faculty od Science, University of Zagreb, Department of Zoology, Croatia 2 Faculty of Teacher Education, University of Zagreb, Croatia 3 National Museum, Department of Zoology, Czechia 4 Charles University, Department of Ecology, Czechia The region of Balkans is often considered as an ichthyologic “hot spot”, with great number of species and high portion of endemics living in fresh waters in a relatively small area. The Adriatic watershed in Croatia and Herzegovina is inhabited by six spined loach species (genus Cobitis) whose extinction risk estimations were based solely on their extent of occurrence (and/or area of occupancy) and its fragmentation, and conservation proposals do not consider diversity below species level. In this investigation we employed molecular genetic methods to describe present genetic structure of the Adriatic spined loaches and reveal their demographic history. The divergence of the Adriatic lineages inside the genus Cobitis started in Miocene and lasted until Pleistocene epoch. Even though all the investigated species inhabit karstic rivers located in the same geographic area and that were subject of similar geological events, the results obtained reveal great differences in their genetic diversity and structure and point out the necessity of different conservation measures to ensure their future viability. High level of genetic polymorphism is characteristic for species located more to the south. Two species comprised of more than one population have completely different intraspecific structure; populations of C. illyrica are genetically distinct and represent separate evolutionary significant units, whereas intraspecific structure of C. narentana corresponds to metapopulational pattern. Without population genetic data, evolutionary significant units could be easily misidentified. Furthermore, the obtained results affirm that population genetic measurements are able to detect differences among closely located and related species and estimate extinction risk even more accurately than currently applied IUCN criteria.
