Glacial events and the formation of ice‐free areas serving as refugia for plants and animals
are important in shaping present patterns of genetic diversity in arctic areas. Beringia …

The Veronica alpina complex comprises eight species of alpine habitats over a wide range
of mountain systems in the Northern Hemisphere. The occurrence of sympatric species in …

Asexual reproduction, polyploidy and hybridization are well-known sources of taxonomic
complexity in angiosperms. All these processes are believed to occur in Potentilla sect …

The Hengduan Mountains (HM) and adjacent regions have been suggested as the
important refugia of the temperate plants during the glacial stages. However, it remains …

The origin of the arctic flora covering the northernmost treeless areas is still poorly
understood. Arctic plants may have evolved in situ or immigrated from the adjacent …

In the last decade a number of studies has illustrated quite different phylogeographical
patterns amongst plants with a northern present-day geographical distribution, spanning the …

Minuartia biflora and Ranunculus pygmaeus are circumarctic plants with a few isolated
occurrences in the European Alps. We analysed amplified fragment length polymorphism …

According to previous phylogeographic studies, high mountains at low latitudes are
important areas for the study of the evolutionary history of arctic–alpine plants in surviving …

There is an ongoing debate about the glacial history of non-arctic species in central and
northern Europe. The two main hypotheses are:(1) postglacial colonization from refugia …

The circumarctic ranges of arctic‐alpine plants are thought to have been established in the
late Pliocene/early Pleistocene, when the modern arctic tundra was formed in response to …
