Abstract
Freshwater fishes of the genus Gobio are widely distributed in Eurasia, where they show great phenotypic similarity between different species, but also considerable intraspecific morphological variability. The genetic research so far showed that there is also a remarkable genetic diversity present within the genus, and that Gobio is genetically very diverse in the Danube River drainage. This research aimed at exploring the genetic diversity and phylogeography of Gobio in Croatia and Austria through DNA barcoding, and additionally investigating the diversity of ectoparasites of the genus Gyrodactylus which reside on Gobio, potentially enhancing our understanding of the host’s phylogeographic patterns through insights from the parasites’. The results of this research uncovered the presence of the new mitochondrial lineage of Gobio in Croatia, which is closely related to other southeast European Gobio species, and a distinct phylogeographic pattern within the genus in Austria and Croatia. The parasites of the genus Gyrodactylus also showed great diversity, with several new lineages uncovered, but without a clear phylogeographic structure. Furthermore, the phylogenetic analysis indicates that Gyrodactylus colonized fishes of the genus Gobio in the Danube River drainage twice independently.
Abstract (croatian)
Slatkovodne ribe roda Gobio široko su rasprostranjene u Euroaziji, gdje pokazuju veliku fenotipsku sličnost među vrstama, ali također značajnu intraspecijsku morfološku varijabilnost. Genska istraživanja dosad provedena na ovim ribama pokazala su da unutar roda postoji velika genska raznolikost i da je ta raznolikost izražena kod pripadnika roda Gobio u dunavskom slijevu. Cilj ovog istraživanja bio je istražiti gensku raznolikost i filogeografiju roda Gobio u Hrvatskoj i Austriji primjenom DNA barkodiranja te istražiti raznolikost ektoparazita roda Gyrodactylus, koji se mogu pronaći na spomenutim ribama, s ciljem boljeg razumijevanja filogeografskih uzoraka domaćina uvidom u filogeografske uzorke parazita. Rezultati ovog istraživanja otkrivaju u Hrvatskoj dosad nepoznatu mitohondrijsku liniju riba roda Gobio, koja je u bliskom srodstvu s drugim vrstama roda Gobio iz jugoistočne Europe te da je prisutan filogeografski uzorak među pripadnicima ovog roda u Austriji i Hrvatskoj. Paraziti roda Gyrodactylus su također pokazali veliku gensku raznolikost te su otkrivene nove genske linije tog roda, međutim nije utvrđeno postojanje jasne filogeografske strukture. Ipak, filogenetska analiza ukazuje na to da su paraziti tog roda dvaput neovisno kolonizirali ribe roda Gobio u dunavskom slijevu.
