“…Prolonged isolation of populations influences their genetic diversity and can be considered as the main force shaping genetic structure of aquatic species in Europe ( Bálint et al, 2011 ; Alp et al, 2012 ; Theissinger et al, 2012 ). Isolated populations of aquatic invertebrates may be found within geomorphological units/subunits of many mountain areas ( Engelhardt, Haase & Pauls, 2011 ; Davis et al, 2013 ; Mamos et al, 2016 ; Čiamporová-Zat’ovičová & Čiampor Jr, 2017 ; Šípošová, Čiamporová Zat’ovičová & Čiampor Jr, 2017 ; Copilaş-Ciocianu et al., 2018 ).…”

The Western Carpathians are a particularly interesting part of the Carpathian Arc. According to recent molecular data upon aquatic and terrestrial taxa, this mountain area is an important biodiversity hotspot of Europe. Moreover, the W Carpathians include rich systems of karst springs inhabited by specific fauna, where molecular diversity and phylogeographic patterns are yet to be fully explored. Our study aims to compare population genetic structure and molecular diversity of two related and commonly co-occurring riffle beetles, Elmis aenea (PWJ Müller, 1806) and Limnius perrisi (Dufour, 1843) in the springs and streams of the W Carpathians using the mitochondrial DNA barcoding fragment of the cytochrome c oxidase subunit I gene (COI). The relatively stable thermal and chemical conditions of springs throughout unfavourable climatic settings make these highly specific lotic systems potentially ideal for a long-term survival of some aquatic biota. Populations of both elmid species were relatively homogeneous genetically, with a single dominant haplotype. However, we revealed that E. aenea significantly dominated in the springs, while L. perrisi preferred streams. Relative isolation of the springs and their stable conditions were reflected in significantly higher molecular diversity of the E. aenea population in comparison to L. perrisi. The results of Bayesian Skyline Plot analysis also indicated the exceptional position of springs regarding maintaining the population size of E. aenea. On the other hand, it seems that streams in the W Carpathians provide more effective dispersal channels for L. perrisi, whose population expanded much earlier compared to E. aenea. Present study points out that different demographic histories of these two closely related elmid species are manifested by their different habitat preference and molecular diversity.
