Understanding the population dynamics of megafauna that inhabited the mammoth steppe
provides insights into the causes of extinctions during both the terminal Pleistocene and …

Radical restructuring of the terrestrial, large mammal fauna living in arctic Alaska occurred
between 14,000 and 10,000 years ago at the end of the last ice age. Steppe bison, horse …

Relict woolly mammoth (Mammuthus primigenius) populations survived on several small
Beringian islands for thousands of years after mainland populations went extinct. Here we …

The late Pleistocene megafaunal extinctions may have been the first extinctions directly
related to human activity, but in North America the close temporal proximity of human arrival …

The end of the Pleistocene in North America saw the extinction of 38 genera of mostly large
mammals. As their disappearance seemingly coincided with the arrival of people in the …

Dozens of large mammals such as mammoth and mastodon disappeared in North America
at the end of the Pleistocene with climate change and “overkill” by human hunters the most …

The mechanisms of Late Pleistocene megafauna extinctions remain fiercely contested, with
human impact or climate change cited as principal drivers. We compared ancient DNA and …

Causes of late Quaternary extinctions of large mammals (“megafauna”) continue to be
debated, especially for continental losses, because spatial and temporal patterns of …

To understand what factors control species colonization and extirpation within specific
paleoecosystems, we analyzed radiocarbon dates of megafaunal mammal species from …

Woolly mammoths in mainland Alaska overlapped with the region's first people for at least a
