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: Analyses of fossil mammal faunas from 2945 localities in the United States demonstrate that the geographic ranges of individual species shifted at different times, in different directions, and at different rates in response to late Quaternary environmental fluctuations.

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.
