“…To date, among the studies including samples from the area only Daneck et al (2016) suggested that a glacial refugium in the eastern part of the Northern Limestone Alps “cannot be excluded” for Rosa pendulina based on somewhat ambiguous Amplified Fragment Length Polymorphism evidence. In contrast, a refugium in the southeastern Alps and the adjacent Balkan Peninsula was strongly supported, for instance, for Cyclamen purpurascens ( Slovák et al, 2012 ) and Hacquetia epipactis ( Urbaniak et al, 2018 ).…”

Evidence for Glacial Refugia of the Forest Understorey Species Helleborus niger (Ranunculaceae) in the Southern as Well as in the Northern Limestone Alps

Glacial refugia of alpine and subnival biota have been intensively studied in the European Alps but the fate of forests and their understory species in that area remains largely unclear. In order to fill this gap, we aimed at disentangling the spatiotemporal diversification of disjunctly distributed black hellebore Helleborus niger (Ranunculaceae). We applied a set of phylogeographic analyses based on restriction-site associated DNA sequencing (RADseq) data and plastid DNA sequences to a range-wide sampling of populations. These analyses were supplemented with species distribution models generated for the present and the Last Glacial Maximum (LGM). We used exploratory analyses to delimit genomically coherent groups and then employed demographic modeling to reconstruct the history of these groups. We uncovered a deep split between two major genetic groups with western and eastern distribution within the Southern Limestone Alps, likely reflecting divergent evolution since the mid-Pleistocene in two glacial refugia situated along the unglaciated southern margin of the Alps. Long-term presence in the Southern Limestone Alps is also supported by high numbers of private alleles, elevated levels of nucleotide diversity and the species’ modeled distribution at the LGM. The deep genetic divergence, however, is not reflected in leaf shape variation, suggesting that the morphological discrimination of genetically divergent entities within H. niger is questionable. At a shallower level, populations from the Northern Limestone Alps are differentiated from those in the Southern Limestone Alps in both RADseq and plastid DNA data sets, reflecting the North-South disjunction within the Eastern Alps. The underlying split was dated to ca. 0.1 mya, which is well before the LGM. In the same line, explicit tests of demographic models consistently rejected the hypothesis that the partial distribution area in the Northern Limestone Alps is the result of postglacial colonization. Taken together, our results strongly support that forest understory species such as H. niger have survived the LGM in refugia situated along the southern, but also along the northern or northeastern periphery of the Alps. Being a slow migrator, the species has likely survived repeated glacial-interglacial circles in distributional stasis while the composition of the tree canopy changed in the meanwhile.

“…It is difficult to ascertain when and how the Allium representatives reached Europe, though most probably from their Asian diversity center, thereby inhabiting new territory and new sites. The migration of plants in this case is a key factor responsible for the observed intraspecific diversity [3,4]. Plants inhabiting new locations and adapting to specific sites often develop local morphologically and/or genetically diverse ecotypes and this seems to be the main reason why many similar populations of rare species were also recognized as having less genetic diversity than more widely distributed species [5].…”

Allium sibiricum is one of the rarest plant species in the Sudetes and Carpathians. Inter simple sequence repeat DNA (ISSR) and morphological analyses were conducted to study the biogeographical relationships between geographically disjunctive populations of A. sibiricum in the Carpathians and Sudetes. The results clearly differentiated the Carpathian and Sudetes populations, but also showed a relatively high level of genetic similarity in specimens within certain groups of the Sudetes and Carpathian populations. The plants collected in the Karkonosze probably belong to a mountain form of A. schoenoprasum morphotype C which inhabits natural sites there. In contrast, the study found morphologically and genetically different plants inhabiting Pilsko Mt in the Carpathians. The plants from the Carpathians were present in scattered sites probably due to the activity of Vlach shepherds and the formation of large pastures. The species enlarged its local range due to this type of anthropopressure and likely hybridized with the cultivated Allium plants introduced by the shepherds. This may indicate that the populations on Pilsko Mt are of a partly anthropogenic character.

“…The present distribution and genetic structure of organisms are consequences of repeated climatic changes in the Pleistocene during the past several million years. The cold periods in the Pleistocene Epoch caused substantial changes in ecosystems, such as organism extinction, habitat fragmentation, and modified vegetation in the colder areas of Europe, America, and the Arctic [1][2][3][4].These climatic changes were also the primary reason for numerous plant or animal migrations to the southern part of Europe or into warmer localities, in front of glaciers, where they were able to survive unfavorable conditions; once favorable conditions returned, they could migrate back to the northern areas [5][6][7]. Such organisms, commonly called glacial relicts, were widely distributed when the climate changed in the Holocene Epoch; the changing climate also caused numerous organisms to adapt to the new climatic conditions and reduced their ranges to smaller refugia, mostly in high mountains, where the arctic boreal conditions and cold climate remained.…”

Microfungal diversity of Juncus trifidus L. and Salix herbacea L. at isolated locations in the Sudetes and Carpathian Mountains

During cold periods in the Pleistocene Epoch, many plants known as the “relict species” migrated and inhabited new areas. Together with plants, some microfungi also migrated, remaining present on plants and in plant communities. However, the relationship between fungi and the migrating plants (especially host plants) is not well understood. Therefore, we examined the diversity and distribution of microfungi associated with two migratory relict plants in the Sudetes and Carpathian Mountains: Salix herbacea L. and Juncus trifidus L. In total, we found 17 taxa of fungi that were collected from nine different locations. Nine fungal taxa were collected on S. herbacea, and eight taxa on J. trifidus. Localities richest of fungi on S. herbacea were Mały Śnieżny Kocioł (Karkonosze Mts, Sudetes) and on J. trifidus, the Tatra Mts (Carpathian Mts). This work provides new insights into the distribution of fungi inhabiting S. herbacea and J. trifidus in Poland.
