Although ancient DNA from sediments (sedaDNA) has been used to investigate past ecosystems, the approach has never been directly compared to the traditional methods of pollen and macrofossil analysis. We conducted a comparative survey of 18 ancient permafrost samples spanning the Late Pleistocene (46–12.5 thousand years ago), from the Taymyr Peninsula in northern Siberia. The results show that pollen, macrofossils and sedaDNA are complementary rather than overlapping, and in combination reveal more detailed information on plant palaeocommunities than can be achieved by each individual approach. SedaDNA and macrofossils share greater overlap in plant identifications than with pollen, suggesting that sedaDNA is local in origin. These two proxies also permit identification to lower taxonomic levels than pollen, enabling investigation of temporal changes in species composition and the determination of indicator species to describe environmental changes. Combining data from all three proxies, reveals an area ... : BAP_1DNA sequences from permafrost sediments: site Baskura Peninsula (Taymyr Peninsula).
