The biogeography of alpine and arctic-alpine species is complex, much more complex than thought until relatively recently. Alpine species survived glacial periods mostly within refugia in close proximity to the mountains where they are found today. One mountain range can be colonised from several glacial refugia, while one refugium can be the source of colonisation of more than one mountain range. The zonal distributions in the glacial cold steppes are only of importance for arctic-alpine species. Their arctic ranges normally derive from there, while the southern mountains were colonised from there or from near-mountain refugia as in the cases of the alpine species.

“…Long-distance dispersal of vascular plant seeds is inherently less likely than that of smaller cryptogam spores, and molecular studies of the Alpine flora have provided only a few examples of long-distance dispersal even within the Alpine massif (Schönswetter et al, 2005). However, disjunct populations of Adenostyles alpina in the mountains of southern Europe appear to result from long-distance dispersal from the Alps and Apennines (Dillenberger & Kadereit, 2013) and, despite the fact that the European lowlands represent a barrier to gene exchange, there is evidence from Carex bigelowii of 'multiple migration events between central and northern Europe' (Schönswetter et al, 2008). There is much evidence for both trans-Atlantic dispersal of the Arctic flora (Abbott & Brochmann, 2003) and of long-distance dispersal within the Arctic (Alsos et al, 2007).…”

What is the origin of the Scottish populations of the European endemic Cherleria sedoides L. (Caryophyllaceae)?Cherleria sedoides L. (Minuartia sedoides (L.) Hiern) is a montane perennial which, with some species in Minuartia sect. Spectabiles, is more closely related to Scleranthus than to other Minuartia species and is therefore best restored to the reinstated and redefined genus Cherleria. Reconstruction of the ancestral area of the clade containing C. sedoides suggests that it evolved in the Alps or the Balkan peninsula. The species now has an unusual distribution, being present in the mountains of southern Europe and Scotland but absent from the Arctic. Three historical scenarios which might have led to the presence of the species in Scotland are outlined and tested by a molecular analysis comparing Scottish populations with populations from the Pyrenees and the Alps. The sampled populations show little variation in ITS/ETS but much more in cpDNA. The latter reveals a major division between some Alpine material and the other Alpine, Pyrenean and Scottish plants. Once the anomalous Alpine haplotypes are excluded, Scottish populations are at least as variable as those from the Alps and Pyrenees, and are closely related to both. We conclude that they have not undergone a long period of isolation, nor have they originated by recent, long-distance dispersal from the Alps or Pyrenees. They appear to be derived from a metapopulation which was probably widespread at the Last Glacial Maximum and gave rise to the Alpine, Pyrenean and Scottish plants.

Carex cespitosa: reappraisal of its distribution in Europe

Jiménez-Mejías P., Hilpold A., Frajman B., Puşcaş M., Koopman J., Mesterházy A., Grulich V., Lye K. Carex cespitosa L. (Cyperaceae) has been traditionally regarded as widespread in Europe, being reported from most countries. However, its distribution is currently overestimated due to the ambiguous use of the name C. cespitosa, together with frequent taxonomic confusion, mainly with the closely related C. elata All. and C. nigra (L.) Reichard. We present a critical revision of the distribution of C. cespitosa in Europe W of the former USSR, based on herbarium material and literature.We confirm the presence of the species in 19 European countries, while its occurrence is considered as doubtful in another five countries. Data pertinent to the ecology and conservation status of the species in the different countries are also provided. It is considered threatened or nearly so in at least eight countries. Hybrids with C. acuta L., C. elata and C. nigra are morphologically characterized and discussed. Although chorological revisions of the European flora are commonly considered of relatively minor scientific relevance, the situation detected by our survey of C. cespitosa reveals the importance of, and need for, these basic works for the accurate knowledge of many species, especially for subsequent works on conservation biology and biogeography.
