    • Sedimentary ancient DNA shows terrestrial plant richness continuously increased over the Holocene in northern Fennoscandia 

      Rijal, Dilli Prasad; Heintzman, Peter D.; Lammers, Youri; Yoccoz, Nigel; Lorberau, Kelsey; Pitelkova, Iva; Goslar, Tomasz; Murguzur, Francisco Javier Ancin; Salonen, J. Sakari; Helmens, Karin F.; Bakke, Jostein; Edwards, Mary E.; Alm, Torbjørn; Bråthen, Kari Anne; Brown, Antony; Alsos, Inger Greve (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-30)
      The effects of climate change on species richness are debated but can be informed by the past. Here, we generated a sedimentary ancient DNA dataset covering 10 lakes and applied novel methods for data harmonization. We assessed the impact of Holocene climate changes and nutrients on terrestrial plant richness in northern Fennoscandia. We find that richness increased steeply during the rapidly warming ...

    • Shotgun Environmental DNA, Pollen, and Macrofossil Analysis of Lateglacial Lake Sediments From Southern Sweden 

      Parducci, Laura; Alsos, Inger Greve; Unneberg, Per; Pedersen, Mikkel Winther; Han, Lu; Lammers, Youri; Salonen, J. Sakari; Väliranta, Minna; Slotte, Tanja; Wohlfarth, Barbara (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-20)
      The lake sediments of Hässeldala Port in south-east Sweden provide an archive of local and regional environmental conditions ~14.5–9.5 ka BP (thousand years before present) and allow testing DNA sequencing techniques to reconstruct past vegetation changes. We combined shotgun sequencing with plant micro- and macrofossil analyses to investigate sediments dating to the Allerød (14.1–12.7 ka BP), Younger ...
