Cryptic northern refugia beyond the ice limit of the Pleistocene glaciations may have had significant influence on the current pattern of biodiversity in Arctic regions. In order to evaluate whether northern glacial refugia existed in the Canadian Arctic, we examined mitochondrial DNA phylogeography in the northernmost species of rodents, the collared lemming (Dicrostonyx groenlandicus) sampled across its range of distribution in the North American Arctic and Greenland. The division of the…

Phylogeographical lineages of Arctic grayling (Thymallus arcticus) in North America: divergence, origins and affinities with Eurasian Thymallus

The data suggest that extant North American Arctic grayling are more diverse phylogeographically than previously suspected and that they consist of at least three major lineages that originated in distinct Pleistocene glacial refugia.

Of glaciers and refugia: a decade of study sheds new light on the phylogeography of northwestern North America

The emergent patterns from this review suggest the classic Beringian‐southern refugial paradigm for northwestern North American biota should be refined and highlighted to highlight the ecological and evolutionary consequences of colonization from multiple refugia.

Hares on ice: phylogeography and historical demographics of Lepus arcticus, L. othus, and L. timidus (Mammalia: Lagomorpha)

Historical demographic estimates for 12 arctic hare populations from throughout their range indicate that L. arcticus and L. othus persisted in two separate North American arctic refugia during glacial advances of the Pleistocene, while the high genetic diversity in L. timidus likely reflects multiple Eurasian refugias.

Refugial persistence and postglacial recolonization of North America by the cold‐tolerant herbaceous plant Orthilia secunda

Analysis of the refugial and recolonization history of the herbaceous plant species Orthilia secunda in North America suggests that O. secunda persisted through the Last Glacial Maximum (LGM) in western refugia, even though palaeodistribution modelling indicated a suitable climate envelope across the entire south of the continent.

Phylogeography of lemmings (Lemmus): no evidence for postglacial colonization of Arctic from the Beringian refugium

There is little evidence for the direct effect of the last glaciation on the level of genetic variation and allele genealogy in lemmings on a regional geographical scale, implying that the population genetic models of postglacial colonization suggested for temperate taxa might have limited applicability for Arctic species.

Comparative Phylogeography Highlights the Double-Edged Sword of Climate Change Faced by Arctic- and Alpine-Adapted Mammals

Similar phylogeographic histories are supported for all species, suggesting that these, and likely other, alpine- and arctic-adapted taxa are already experiencing population and/or range declines that are likely to synergistically accelerate in the face of rapid climate change.

Phylogeography of higher Diptera in glacial and postglacial grasslands in western North America

Populations of Diptera in Yukon grasslands could have persisted in steppe habitats in Beringia through Pleistocene glaciations and had high haplotype diversity, which could suggest survival in a Beringian refugium.

Evolutionary reconstruction supports the presence of a Pleistocene Arctic refugium for a large mammal species

The presence of refugia in the Canadian High Arctic has been subject to debate for decades. We investigated the potential existence of Arctic refugia during the Pleistocene for a large mammal species

Glacial refugia and the phylogeography of Steller's sea lion (Eumatopias jubatus) in the North Pacific

Phylogenetic analysis suggests the genetic structure of E. jubatus is the result of Pleistocene glacial geology, which caused the elimination and subsequent reappearance of suitable rookery habitat during glacial and interglacial periods.

Phylogeography of wolves (Canis lupus) in the Pacific Northwest

Analysis of variation of mitochondrial control region sequences corroborate previous microsatellite analyses supporting independent evolutionary histories for Coastal and Continental wolves in North America and suggests the possibility of 3 temporally independent colonizations of North America by wolves from Asia.



Phylogeography and mitochondrial DNA (mtDNA) diversity in North American collared lemmings (Dicrostonyx groenlandicus)

The division of D. groenlandicus in two phylogeographical groups with limited divergence across the Mackenzie River is consistent with the separation of this species in more than one refugial area located to the northwest of the Laurentide ice sheet during the last glaciation.

The importance of ice ages in diversification of arctic collared lemmings (Dicrostonyx): evidence from the mitochondrial cytochrome b region

The mtDNA phylogeny supports the division of Dicrostonyx into four species suggested on the basis of karyotypes and hybridisation experiments, the Eurasian D. torquatus and the North American D. groenlandicus, D. hudsonius and D. richardsoni, and gives support for the importance of vicariant events generated by the glacial-interglacial periods for speciation in the chromosomally variable DicroStonyx.

Molecular phylogeography of Dryas integrifolia: glacial refugia and postglacial recolonization

The analysis of haplotype diversity revealed several groups of haplotypes having present‐day geographical ranges that overlap locations postulated from geographical and fossil evidence to have been glacial refugia, inferring that two important refugial sources of Arctic recolonization by this species were Beringia and the High Arctic.

The Origin of Diversity in Mammals of the Canadian Arctic Tundra

The 17 modern Canadian arctic tundra mammals share only six broad patterns of taxonomic variation and geographic distribution. These are believed to result from differing distributions during the

Cryptic northern refugia and the origins of the modern biota

Post-glacial re-colonization of European biota

Diversity from southern to northern Europe in the extent of allelic variation and species subdivision is seen; this is attributed to rapid expansion northward and the varied topography of southern refugia allowing populations to diverge through several ice ages.


The results are most consistent with the hypothesis that isolated populations of rock ptarmigan diverged in multiple refugia during the Wisconsin glaciation and that geographic variation reflects patterns of recolonization of the Nearctic after the ice receded.

Molecular analysis of plant migration and refugia in the Arctic.

A phylogenetic analysis of chloroplast DNA variation in the purple saxifrage indicates that this plant first occurred in the Arctic in western Beringia before it migrated east and west to achieve a circumpolar distribution.

It seems likely that, after colonization of Scandinavia in the Late Pleistocene, the Norwegian lemming suffered a reduction in its population effective size and survived the last glacial maximum in some local Scandinavian refugia, as suggested by early biogeographical work.

Some genetic consequences of ice ages, and their role in divergence and speciation

The genetic effects of pleistocene ice ages are approached by deduction from paleoenvironmental information, by induction from the genetic structure of populations and species, and by their
