Late Quaternary dynamics of Arctic biota from ancient environmental genomics

Nature, Published online: 20 October 2021; doi:10.1038/s41586-021-04016-x

A large-scale metagenomic analysis of plant and mammal environmental DNA reveals complex ecological changes across the circumpolar region over the past 50,000 years, as biota responded to changing climates, culminating in the postglacial extinction of large mammals and emergence of modern ecosystems.
