BCST - The collapse of the mammoth steppe: a Yukon perspective
Beringia Centre Science Talks (#BCST) are back for a fourth season! Join us as we explore fascinating topics in archaeology, natural science, and palaeontology.
For this talk, we'll be joined by Dr. Ali Monteath and BCST alum Dr. Duane Froese to discuss the collapse of the mammoth steppe.
During the ice age, Yukon, Alaska and Eurasia were part of a vast biome called the mammoth steppe. This environment has no modern analogue and supported iconic large mammals – the megafauna – including woolly mammoth, steppe-bison and Beringian lion. Around 14,000 years ago this biome collapsed and was replaced by wetter soils and woody, shrub vegetation. In this talk, Dr. Froese and Dr. Monteath will discuss new findings from a special site in Yukon that record this environmental collapse in exceptional detail.
