Sažetak
Aurinia is an exclusively diploid genus comprising of seven species with the centre of origin and diversity in south-eastern Europe. Aurinia saxatilis is the most widely distributed species ranging from the central, eastern and southern Balkan Peninsula and adjacent shores of the western Asia Minor and the southern Apennine Peninsula, over the Carpathians to central Europe and growing on rocky grounds and dry soils. Due to its morphological variability it has been divided into three subspecies: typical A. saxatilis subsp. saxatilis is widespread in central and south- eastern Europe, subsp. orientalis is distributed in the Balkan Peninsula, the southern Carpathians and the western Anatolia, whereas subsp. megalocarpa is limited to the southern Apennine Peninsula and the Aegean region. The aim of this study was to provide insights into spatiotemporal diversification of the species by exploring its evolutionary dynamics and phylogeographic patterns using a combination of phylogenomic (RADseq), and phylogenetic (plastid ndhF) data as well as species distribution models. The inferred phylogenies retrieved three main geographically distinct lineages. The southern lineage is distributed throughout the Aegean area, southern Balkan Peninsula and southern Apennine Peninsula, and corresponds to the species main distribution area during the LGM. The eastern lineage extends from the eastern Balkan Peninsula over the Carpathians towards central Europe, while the central lineage occupies the central Balkan Peninsula. Molecular dating places diversification of all three lineages into the early to middle Pleistocene, indicating their long term independent evolutionary trajectories. Moreover, our data suggest an early divergence and stable in situ persistence of the southernmost populations, whereas the central Balkan and Carpathian populations experienced more complex range dynamics triggered by Pleistocene climatic oscillations. Finally, the extant genetic variation is congruent with the taxonomic separation of subsp. saxatilis and subsp. orientalis, whereas the taxonomic value of subsp. megalocarpa remains doubtful.
