Refugia revisited: individualistic responses of species in space and time
TLDR
Overall, it seems clear that there is large variation in both the size of refugia and the duration during which species are confined to them, which has implications for the role ofRefugia in the evolution of species and their genetic diversity.
Estimating the phylogeny and divergence times of primates using a supermatrix approach
TLDR
This work presents an up-to-date, comprehensive estimate of the structure and tempo of primate evolutionary history, using Bayesian phylogenetic methods to analyze data supermatrices from 219 species across 67 genera and 3 nuclear genes from 26 genera.
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.
Rise and Fall of the Beringian Steppe Bison
TLDR
A detailed genetic history of bison throughout the late Pleistocene and Holocene epochs is reconstructed using ancient DNA and Bayesian techniques to reconstruct a large diverse population living throughout Beringia until around 37,000 years before the present, when the population's genetic diversity began to decline dramatically.
The genome of a Late Pleistocene human from a Clovis burial site in western Montana
TLDR
The genome sequence of a male infant recovered from the Anzick burial site in western Montana is sequenced and it is shown that the gene flow from the Siberian Upper Palaeolithic Mal’ta population into Native American ancestors is also shared by the AnZick-1 individual and thus happened before 12,600 years bp.
Assessing ancient DNA studies.
The Beaker Phenomenon and the Genomic Transformation of Northwest Europe
TLDR
Genome-wide data from 400 Neolithic, Copper Age and Bronze Age Europeans is presented, finding limited genetic affinity between Beaker-complex-associated individuals from Iberia and central Europe, and excludes migration as an important mechanism of spread between these two regions.
Staying out in the cold: glacial refugia and mitochondrial DNA phylogeography in ancient European brown bears
TLDR
This work proposes continuous gene flow across southern Europe, from which brown bear populations expanded after the last glaciation, and shows a complex phylogeographical history for western European populations.
