TL;DR: 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.

TL;DR: The reconstructed matrilineal history of brown and polar bears has two striking features: first, it is punctuated by dramatic and discrete climate-driven dispersal events, and second, opportunistic mating between these two species as their ranges overlapped has left a strong genetic imprint.

TL;DR: This article used a massively parallel sequencing method that allows large numbers of single DNA strands to be sequenced, and showed that modifications of C, as well as to a lesser extent of G, residues cause such misincorporations.

TL;DR: 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.

TL;DR: It is concluded that neither the effects of climate change nor human hunting alone can be responsible for the decline of the cave bear and suggested that a complex of factors including human competition for cave sites lead to the caveBear's extinction.
