The potential of lacustrine sedimentary ancient DNA for revealing human postglacial recolonization patterns in northern Sweden – a review
The postglacial recolonization of Fennoscandian flora and fauna was initiated when the land became accessible as the last ice sheet retreated. In northern Sweden, plants are represented in pollen and macrofossil records, but there is no genetic evidence from the first plants, animals or humans in th...
