Phylogeography of the Russian flying squirrel (Pteromys volans): implication of refugia theory in arboreal small mammal of Eurasia.
TLDR
A phylogeographical study of the Russian flying squirrel (Pteromys volans) was carried out using the complete mitochondrial (mt) cytochrome b gene sequences with special reference to the refugia theory for the arboreal traits of this species as mentioned in this paper.Abstract:
A phylogeographical study of the Russian (Siberian) flying squirrel (Pteromys volans) was carried out using the complete mitochondrial (mt) cytochrome b gene sequences with special reference to the refugia theory for the arboreal traits of this species. We examined 31 specimens from 24 localities, resulting in 28 haplotypes. One breeding specimen with a unique haplotype from Hokkaido, Japan was included in the phylogenetic analysis. There were three mtDNA lineages: Hokkaido, Far Eastern, and northern Eurasia. Divergence data among lineages demonstrated that the Hokkaido group separated from the other groups during the Holsteinian interglacial. The phylogeographical pattern of P. volans is different from that previously reported for terrestrial rodents associated with treeless habitats. Unlike grasslands, forests decreased during glaciation and moved southward because of the cold and arid environmental conditions. The glacial refugia of P. volans would have been associated with forest dynamics in the Pleistocene.read more

Molecular biogeography of Europe: Pleistocene cycles and postglacial trends
TL;DR: An overview of the molecular biogeography of Europe is given, which supports the strong linkage between southwestern Alps and Pyrenees, northeastern Alps and Carpathians as well as southeastern Alps and the Dinaric mountain systems, hereby allowing conclusions on the glacial distribution patterns of these species.

Extra-Mediterranean refugia: The rule and not the exception?
Thomas Schmitt,Zoltán Varga +1 more
TL;DR: Recent genetic analyses revealed that typical Mediterranean species have also survived the Last Glacial Maximum in cryptic northern refugia (e.g. in the Carpathians or even north of the Alps) in addition to their Mediterranean refuge areas.

Climate, history and neutrality as drivers of mammal beta diversity in Europe: insights from multiscale deconstruction.
TL;DR: European mammal beta diversity mainly reflects spatial turnover and only to a limited extent nestedness and is driven by current climate in combination with historical - and perhaps, neutral - dynamics, suggesting that a key challenge for climate-change predictive studies will be taking the influence of non-climatic factors into account.

TL;DR: The brown bear has proved a useful model for studying Late Quaternary mammalian phylogeography as discussed by the authors, but information is lacking from northern continental Eurasia, which constitutes a large part of the species' current distribution.

Molecular phylogeography of European Sciurus vulgaris: refuge within refugia?
Andrea Grill,Giovanni Amori,Gaetano Aloise,Irene Lisi,Guido Tosi,Lucas A. Wauters,Ettore Randi +6 more
TL;DR: Geographical distribution of mtDNA haplotypes and mismatch analysis suggest a common refugium for the red squirrel across most of its present range from which expansion happened rather rapidly, and the genotype mixing of italicus with northern populations could be a residual of postglacial expansion.

Confidence limits on phylogenies: an approach using the bootstrap.
TL;DR: The recently‐developed statistical method known as the “bootstrap” can be used to place confidence intervals on phylogenies and shows significant evidence for a group if it is defined by three or more characters.
