Dynamics of Pleistocene population extinctions in Beringian brown bears
The climatic and environmental changes associated with the last glaciation (90,000 to
10,000 years before the present; 90 to 10 ka BP) are an important example of the effects of …

Rise and fall of the Beringian steppe bison
The widespread extinctions of large mammals at the end of the Pleistocene epoch have
often been attributed to the depredations of humans; here we present genetic evidence that …

Genomic sequencing of Pleistocene cave bears
Despite the greater information content of genomic DNA, ancient DNA studies have largely
been limited to the amplification of mitochondrial sequences. Here we describe …

Population genetics of Ice Age brown bears
JA Leonard, RK Wayne… - Proceedings of the …, 2000 - National Acad Sciences
The Pleistocene was a dynamic period for Holarctic mammal species, complicated by
episodes of glaciation, local extinctions, and intercontinental migration. The genetic …

Glacial ice supports a distinct and undocumented polar bear subpopulation persisting in late 21st-century sea-ice conditions
Polar bears are susceptible to climate warming because of their dependence on sea ice,
which is declining rapidly. We present the first evidence for a genetically distinct and …

Withering away—25,000 years of genetic decline preceded cave bear extinction
The causes of the late Pleistocene megafaunal extinctions are still enigmatic. Although the
fossil record can provide approximations for when a species went extinct, the timing of its …

[HTML][HTML] Ancient DNA analysis reveals divergence of the cave bear, Ursus spelaeus, and brown bear, Ursus arctos, lineages
O Loreille, L Orlando, M Patou-Mathis, M Philippe… - Current Biology, 2001 - cell.com
The cave bear, Ursus spelaeus, represents one of the most frequently found paleontological
remains from the Pleistocene in Europe. The species has always been confined to Europe …

Arctic-adapted dogs emerged at the Pleistocene–Holocene transition
Although sled dogs are one of the most specialized groups of dogs, their origin and
evolution has received much less attention than many other dog groups. We applied a …

Retreat and extinction of the Late Pleistocene cave bear (Ursus spelaeus sensu lato)
The cave bear (Ursus spelaeus sensu lato) is a typical representative of Pleistocene
megafauna which became extinct at the end of the Last Glacial. Detailed knowledge of cave …

Species-specific responses of Late Quaternary megafauna to climate and humans
Despite decades of research, the roles of climate and humans in driving the dramatic
extinctions of large-bodied mammals during the Late Quaternary period remain contentious …
