Abstract Marine sediments as excellent climate archives, contain among other biomolecules substantial amounts of extracellular DNA. Through mineral binding, some the DNA remains protected from degradation which aids its preservation. While this pool represents genomic ecosystem fingerprints spanning over millions years, capability current extraction methods in recovering mineral‐bound poorly understood. We evaluated sedimentary approaches and their ability to recover short fragments artificially created DNA‐mineral complexes involving pure clay minerals or quartz, well different types natural marine sediments. separately investigated lysis (DNA release) isolation steps (purification DNA) comparing five buffers across two commonly used approaches: silica magnetic beads liquid‐phase organic purification. The choice buffer significantly impacted amount recovered facilitated selective desorption fragments. High molarity EDTA phosphate on average an order magnitude more than tested buffers, while both comparable In sediments, however, caused inhibitory effects subsequent downstream applications (e.g., PCR), all assessed extracts, induced inhibition only half extracts. Thus, approach, together with buffer, played a decisive role successful library preparation ultimately impacting final fragment distribution. With study, we underscore critical importance selection maximize recovery show profound impact lengths extractions, crucial factor alongside existing facilitating high‐quality extracts for analysis related ancient environmental research.

The postglacial recolonization of Fennoscandian flora and fauna was initiated when the land became accessible as last ice sheet retreated. In northern Sweden, plants are represented in pollen macrofossil records, but there is no genetic evidence from first plants, animals or humans region, mainly owing to an absence osteological finds. questions who peoples, pioneers, were where they came therefore remain unanswered. Previous palaeogenomic analyses remains adjacent regions have suggested that two main routes into Sweden could been taken by one SW through modern‐day Denmark Norway, east via Finland. However, direct pioneers exists. Modern technology has provided ancient DNA field with updated toolbox allow for novel approaches revealing origin profiles Scandinavians, which sedimentary (sedaDNA) well placed. Lake sediments now a routine source sedaDNA used record environmental changes detect species lived surrounding lake catchment. This review will provide context background, summary ground‐breaking studies within lacustrine sedaDNA, relevant methodology address scientific at hand. We conclude mature enough insight origins arrival times migrated Sweden.
