“…Several recent studies have corroborated earlier findings and provided further genetic evidence for a close biogeographical relationship between the Western Carpathians and the Eastern Alps (also observed in species distribution patterns and community compositions; Puşcaş & Choler, ). Populations from these two areas often share closely‐related genetic lineages (Ronikier et al ., ; Drag et al ., ; György et al ., ) and such affinities have been documented even for microbial communities in high‐mountain grasslands (Geremia et al ., ). Nevertheless, numerous cases of genetic divergence suggesting long‐term isolation of West Carpathians and Eastern Alps populations, often pre‐dating the last glaciation, have also been documented (Dzialuk et al ., ; Homburg et al ., ; Ronikier & Zalewska‐Gałosz, ; Pachschwöll et al ., ; Drees et al ., ; Frajman, Graniszewska & Schönswetter, ).…”

The Carpathians are the largest mountain range in Central Europe. Their geographical position, extent, isolation, landscape heterogeneity, well‐preserved environment, and relatively low impact of Quaternary glaciations make them of utmost importance for studies on European biodiversity and biogeography. In this review, introducing a Special Issue of the Biological Journal of the Linnean Society, we provide an overview of current research and focus on three main aspects: (1) distribution patterns and species richness including endemism; (2) phylogeographical patterns, inference of major barriers, and divergence areas; and (3) cytological studies and cytogeography inferred from vascular plant polyploid complexes. Our survey shows that, although accurate estimation is not possible for several important taxonomic entities because of unavailable or dispersed data, the Carpathians are a clear hotspot of European diversity for many groups of organisms, such as mammals, breeding birds, amphibians, lichens, and vascular plants. Certain groups, not necessarily those with high species richness, are rich in endemic taxa. This holds mainly for subterranean invertebrates, molluscs, grasshoppers, beetles, spiders, and vascular plants. Distribution patterns of endemic richness vary across taxonomic groups, as well as geographically, reflecting both history and habitat features. In general, the South‐Eastern Carpathians have a significantly higher proportion of endemic taxa than the northerly‐situated Western Carpathians. Molecular clock‐based estimations have provided some insight into the diversification age of the Carpathian biota, including a Tertiary origin for some endemic taxa and lineages, especially those confined to environmentally stable habitats. Distribution patterns, as well as phylogeographical and phylogenetic data, corroborate the persistence of many high‐mountain and forest taxa during the Quaternary climatic oscillations, often in multiple spatially delimited areas isolated by physical barriers. Several studies show that the Carpathian massifs played an important role as refugia for rare lineages and/or as stepping stones in migrations. Phylogeographical analysis reveals clear patterns of biogeographical breaks, as well as links, although clear exceptions also confirm that extant distribution patterns are often shaped more by idiosyncratic processes acting at different geological times. Cytogeographical data also uncover several consistent patterns, which probably reflect a deeper evolutionary history. In conclusion, the available data highlight the unique position of the Carpathians in the evolution and preservation of European biota within the European Alpine System.

“…Although in many arctic‐alpine species postglacial colonization of northern Europe, Scandinavia was supposed to be from the EAS in case of R. rosea we only could detect a strong relation between the northern amphi‐Atlantic coastal parts and the British Isles. However, our former study based on microsatellite markers has already revealed the genetic differentiation of the Scandinavian populations from that of the EAS (György et al, ). The high variation and distinct genetic pattern preserved in the Alpine and Carpathian populations emphasizes the role of the EAS in the diversification of R. rosea most probably dating back to the glacial cycles of the Pleistocene and supporting the existence of long‐standing refugia.…”

“…Also all other loci studied confirm diversification in the region of the EAS(Figures 3 and 4). Our former study based on nuclear microsatellites has already revealed that the Eastern Alps and the Dolomites exhibit a distinct genetic pattern compared to other Alpine regions and might have served as possible refugia for R. rosea(György et al, 2016) in the EAS. Indeed, several phylogeographical studies on alpine perennial plant species have mentioned the Eastern Alps and the surrounding lower mountainous regions as refugial territories, where species probably survived during the glacial cycles of the Pleistocene and could have recolonized the Alps in the postglacial(Mráz et al, 2007;Schönswetter et al, 2005;Tribsch & Schönswetter, 2003).…”

Our study describes genetic lineages and historical biogeography of Rhodiola rosea a widely distributed arctic‐alpine perennial species of the Northern Hemisphere based on sequence analysis of six chloroplast regions. Specimens of 44 localities from the Northern Hemisphere have been sequenced and compared with those available in the GenBank. Our results support the migration of the species into Europe via the Central Asian highland corridor, reaching the European Alpine System (EAS) and also the western European edge, the British Isles. The EAS proved to be an important center of genetic diversity, especially the region of the Eastern Alps and the Dolomites where signs of glacial refugia was observed. Apart from those of the EAS, a common lineage was detected along the Atlantic coast from the British Isles toward Scandinavia as well as Iceland and the eastern parts of North America. Accordingly, the British Isles represent a main link between the northern Atlantic and southern EAS lineages.

“…Conversely, recent colonization events from one mountain range to the other, manifested by weak genetic differentiation and diversity loss caused by founder effects, have been suggested, for instance, for Comastoma tenellum (Schönswetter et al., ) and Ranunculus alpestris (Paun et al., ). So far, evidence for a broader population expansion and connectivity between these presently disjunct areas during colder glacial periods is scant (see György et al., ).…”

Premise Disjunct distributions have been commonly observed in mountain plant species and have stimulated phylogeographic and phylogenetic research. Here we studied Alyssum repens, a member of the polyploid species complex A. montanum−A. repens, which exhibits SE Alpine‐Carpathian disjunctions with a large elevational span and consists of diploid and tetraploid populations. We aimed to investigate the species‘ genetic and cytotype structure in the context of its distribution patterns, to elucidate the polyploid origins and to propose an appropriate taxonomic treatment. Methods We combined AFLP fingerprinting markers, sequence variation of the highly repetitive ITS region of rDNA and the low‐copy DET1 nuclear gene, genome size, and morphometric data. Results We identified four geographically structured genetic lineages. One consisted of diploid populations from the foothills of the Southeastern Alps and neighboring regions, and the three others were allopatric montane to alpine groups comprising diploids and tetraploids growing in the Southeastern Carpathians and the Apuseni Mts. in Romania. Conclusions We inferred a vicariance scenario associated with Quaternary climatic oscillations, accompanied by one auto‐ and two allopolyploidization events most likely involving a northern Balkan relative. Whereas genetic differentiation and allopatric distribution would favor the taxonomic splitting of this species, the genetic lineages largely lack morphological distinguishability, and their ecological, cytotype and genome size divergence is only partial. Even though we probably face here a case of incipient speciation, we propose to maintain the current taxonomic treatment of Alyssum repens as a single, albeit variable, species.
