TL;DR: In this article, the authors synthesize the state-of-the-art analytical procedures for effective sampling, extraction, amplification, quantification and/or generation of DNA inventories from sedimentary ancient DNA via high-throughput sequencing technologies.

TL;DR: The objective was to establish an experimental procedure and show direct measurements that unequivocally can be assigned as a baseline for inferring the presence of DNA in lake sediments from the sediments themselves.
Journal ArticleDOI

Journal ArticleDOI
Geochemical identification of potential DNA-hotspots and DNA-infrared fingerprints in lake sediments
TL;DR: In this article, the effect of mineral and organic matter on DNA binding in lake sediments was examined, and a simple model based on sediment geochemistry was proposed to determine potential DNA-hotspots in sediments.
Journal ArticleDOI
Tracking mineral and geochemical characteristics of Holocene lake sediments: the case of Hotagen, west-central Sweden
TL;DR: In this paper, a 2.3 m lake sediment core was collected from Hotagen, a lake in west-central Sweden; a sediment sample was collected every 5 cm, and another part was kept untreated (named bulk) and another portion was size-fractionated into 64 ǫm subsamples.
