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.

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.
Population history and genetic structure of a circumpolar species: the arctic fox
The circumpolar arctic fox Alopex lagopus thrives in cold climates and has a high migration rate involving long-distance movements. Thus, it differs from many temperate taxa that were subjected to ...
Intraspecific phylogenetic analysis of Siberian woolly mammoths using complete mitochondrial genomes

Five new complete mitochondrial DNA genomes of Siberian woolly mammoth are reported, sequenced with up to 73-fold coverage from DNA extracted from hair shaft material, demonstrating the existence of two apparently sympatric mtDNA clades that exhibit high interclade divergence.
Identifying species from pieces of faeces
Genetic analyses on samples collected between 1989 and 2004 indicated an ongoing genetic drift and inbreeding within the Scandinavian populations, and the finding of four isolated populations within Scandinavia and an ongoing inbreeding depression suggests that the risk of extinction is higher than previously thought.
Complete Genomes Reveal Signatures of Demographic and Genetic Declines in the Woolly Mammoth
Sea ice occurrence predicts genetic isolation in the Arctic fox
It is shown that occurrence of sea ice is the key predictor and explained 40–60% of the genetic distance among populations and identified the Commander and Pribilof Islands Arctic populations as genetically unique suggesting they deserve special attention from a conservation perspective.
