The separation of populations by ice sheets into large refugia can account for much of the genetic diversity found in present day populations. [] Key Method To examine refugial origins of North American mountain sheep Ovis spp., we analyzed a 604 bp portion of the mitochondrial DNA (mtDNA) control region from 223 O. dalli and O. canadensis. Major refugia were identified in eastern Beringia and southern North America, and we found evidence for two smaller refugia situated between the Laurentide and…

Phylogeographic insights into cryptic glacial refugia.

HOT SPOTS OF GENETIC DIVERSITY DESCENDED FROM MULTIPLE PLEISTOCENE REFUGIA IN AN ALPINE UNGULATE

TLDR
Across their range, mountain goats were highly genetically structured and displayed the expected pattern of declining diversity toward the periphery, and Gene flow was high within contiguous mountain ranges, but cross‐assignments paradoxically suggest that long‐distance contemporary dispersal movements are not uncommon.

Genome‐wide set of SNPs reveals evidence for two glacial refugia and admixture from postglacial recolonization in an alpine ungulate

TLDR
The results show that glaciation events can have a major role in the evolution of species inhabiting previously glaciated habitats and the need to look beyond established refugia when examining the evolutionary history of such species.

Postglacial range expansion from northern refugia by the wood frog, Rana sylvatica

TLDR
Clustering analyses based on morphology further support a distinction between eastern and western wood frogs and suggest that postglacial migration has played an important role in generating broad‐scale patterns of phenotypic variation in this species.

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

TLDR
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.

From glacial refugia to modern populations: new assemblages of organelle genomes generated by differential cytoplasmic gene flow in transcontinental black spruce

TLDR
Black spruce postglacial colonization unexpectedly resulted in an increase in genetic diversity with possible adaptive consequences, and the patterns of variation in Alaska for both cpDNA and mtDNA markers suggested that black spruce survived the last glacial maximum in this northern region.

Étude phylogéographique comparée des polymorphismes des génomes chloroplastique et mitochondrial de l'épinette noire

TLDR
The genogeographic structure and postglacial history of black spruce (Picea mariana), a transcontinental North American boreal conifer, was inferred using chloroplast DNA Inicrosatellite markers, and it was revealed that gene flow was more efficient through pollen than seeds.

The ‘Expansion–Contraction’ model of Pleistocene biogeography: rocky shores suffer a sea change?

TLDR
The results indicate that the LGM did not extirpate the majority of species in the northeastern Pacific; instead, regional persistence during the L GM appears a common biogeographic history for rocky‐shore organisms in this region.

Contradictions and Concordances in American Colonization Models

The traditional view of American colonization during the late Pleistocene has largely been conditioned on early conceptions of the timing and extent of continental glaciations and the age and

TLDR
The data demonstrate that the current subspecies designation does not reflect the mtDNA phylogeography of the species, which in turn may indicate that morphological differences among subspecies have evolved as adaptive responses to postglacial environmental change.

TLDR
The phylogeographical structure and sparse fossil records indicate that, during the last glaciation, some biologically significant refugia and important sources of postglacial colonization were located to the northwest of the main ice sheet in the Canadian Arctic.

A TEST OF THE GLACIAL REFUGIUM HYPOTHESIS USING PATTERNS OF MITOCHONDRIAL AND NUCLEAR DNA SEQUENCE VARIATION IN ROCK PTARMIGAN (LAGOPUS MUTUS)

TLDR
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.

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

TLDR
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.

TLDR
It is proposed that Pleistocene hybridization and incomplete lineage sorting have resulted in reduced subdivision of interpopulational variation so that gene flow may not be as high as indicated.

Molecular analysis of plant migration and refugia in the Arctic.

TLDR
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.

Mitochondrial-DNA Variation and Genetic-Population Structure in Rocky Mountain Bighorn Sheep (Ovis canadensis canadensis)

TLDR
Phylogeographic analysis suggested that gene flow has occurred on a regional scale at some time in the past and that populations have not been subdivided by long-term biogeographic barriers, and significant differentiation in mtDNA-haplotype frequencies among herds suggested that little gene flow currently exists among populations.

Molecular phylogeography of Dryas integrifolia: glacial refugia and postglacial recolonization

TLDR
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.
