The Bering Land Bridge connecting North America and Eurasia was periodically exposed and inundated by oscillating sea levels during the Pleistocene glacial cycles. This land connection allowed the intermittent dispersal of animals, including humans, between Western Beringia (far north-east Asia) and Eastern Beringia (north-west North America), changing the faunal community composition of both continents. The Pleistocene glacial cycles also had profound impacts on temperature, precipitation, and… 
Ancient horse genomes reveal the timing and extent of dispersals across the Bering Land Bridge
TLDR
The results suggest that barriers to gene flow played an important role in shaping the early genetic history of caballine horses, including the ancestors of living horses within Equus ferus.
Whole genome sequencing reveals a complex introgression history and the basis of adaptation to subarctic climate in wild sheep
TLDR
The data suggest introgression as a mechanism facilitating adaptation in wild sheep species and provide insights into the genetic mechanisms underlying cold adaptation in snow sheep.
Insights into bear evolution from a Pleistocene polar bear genome
TLDR
It is found that principal direction of ancient allele sharing was from brown bear into polar bear, although gene flow between them has likely been bidirectional, which inverts the current paradigm of unidirectional gene flow from polar into brown bear.
INITIAL HUMAN COLONIZATION OF THE AMERICAS, REDUX
ABSTRACT The study of the peopling of the Americas has been transformed in the past decade by astonishing progress in paleogenomic research. Ancient genomes now show that Native American ancestors
An age-depth model and revised stratigraphy of vertebrate-bearing units in Natural Trap Cave, Wyoming
TLDR
It is demonstrated that it is unlikely a prominent snow cone existed or contributed to the pattern of sediment and fossil distribution within the study area, and there does not observe a continuous Pleistocene-Holocene transition in theStudy area.

Dynamics of Pleistocene Population Extinctions in Beringian Brown Bears
TLDR
Researchers studied genetic change in the brown bear, Ursus arctos, in eastern Beringia over the past 60,000 years using DNA preserved in permafrost remains to investigate the evolutionary impact of climatic and environmental changes associated with the last glaciation.
Phylogeography of lions (Panthera leo ssp.) reveals three distinct taxa and a late Pleistocene reduction in genetic diversity
TLDR
Potential evidence of a severe population bottleneck in the cave lion during the previous interstadial is found, adding to evidence from bison, mammoths, horses and brown bears that megafaunal populations underwent major genetic alterations throughout the last interstadials, potentially presaging the processes involved in the subsequent end‐Pleistocene mass extinctions.
Bison phylogeography constrains dispersal and viability of the Ice Free Corridor in western Canada
TLDR
The chronology supports a habitable and traversable corridor by at least 13,000 cal y BP, just before the first appearance of Clovis technology in interior North America, and indicates that the corridor would not have been available for significantly earlier southward human dispersal.
A range-wide synthesis and timeline for phylogeographic events in the red fox (Vulpes vulpes)
TLDR
The phylogeographic history of red foxes is highly similar to that previously described for grey wolves and brown bears, indicating that climatic fluctuations and habitat changes since the Pleistocene had similar effects on these highly mobile generalist species.
Molecular phylogeography of the brown bear (Ursus arctos) in Northeastern Asia based on analyses of complete mitochondrial DNA sequences.
TLDR
The maternal phylogeny of the brown bear is reconstructed and estimated divergence times are estimated to investigate the timing of brown bear migrations, especially in northeastern Eurasia.

The Pleistocene was a dynamic period for Holarctic mammal species, complicated by episodes of glaciation, local extinctions, and intercontinental migration. The genetic consequences of these events
New carbon dates link climatic change with human colonization and Pleistocene extinctions
TLDR
Many new radiocarbon dates are added to those already published on late Pleistocene fossils from Alaska and the Yukon Territory and show previously unrecognized patterns, indicating a radical ecological sorting during a uniquely forage-rich transitional period, affecting all large mammals, including humans.
Range‐wide multilocus phylogeography of the red fox reveals ancient continental divergence, minimal genomic exchange and distinct demographic histories
TLDR
These findings support a model of peripatric speciation and are consistent with the previous classification of the North American red fox as a distinct species, V. fulva.
