Sedimentary ancient DNA over a period of last ~14,500 years

Biodiversity of Eukaryotes was described using universal phylogenetic marker gene with a well-preserved sediment core over last post-glacial period - a period of last ~14,500 years in North-Eastern Europe. Sedimentary ancient DNA (sedaDNA) was extracted from the minuscule sediment samples with ~150 year intervals step and amplified at a low amplification level from each sub-sample.
