The Carpathians are one of the largest mountain ranges in Europe featuring high biodiversity. Currently, up to 1.700 lichen species are listed from the Western and 1.300 lichen species from the Eastern Carpathians. Several interesting elements grow here – such as Arctic-alpine (Arctoparmelia centrifuga, Bellemerea alpina, Nephroma arcticum, N. expallidum, Ramalina carpathica, Umbilicaria aprina,), Atlantic (Phaeographis dendritica, Xanthoparmelia mougeotii), or Mediterranean ones (Leptogium ferax, L. hildenbrandii, Placolecis opaca, Solenopsora candicans, S. cesatii). Despite large number of data on evolution and ecology of the Mediterranean biota, we know very little about survival and diversification of Mediterranean elements in the Carpathians. We focus our study on the questions whether mediterranean model species could survive glacial period and eventually diversify here. Model objects are species of the genus Solenopsora – S. candicans and S. cesatii – within the recently described family Leprocaulaceae, with wider biogeographic/ecological amplitudes reaching their north-eastern distribution limit in the Carpathians. Based on Sanger sequence data (nrITS, β-tubulin) we study their genetic diversity within and among sampling sites. Our aim is to disclose whether any variation exists across the distribution range, and if so infer the origin of the taxa and possibly identify evolutionary processes responsible for the genetic variation.
