    • High resolution ancient sedimentary DNA shows that alpine plant diversity is associated with human land use and climate change 

      Garces Pastor, Sandra; Alsos, Inger Greve; Coissac, Eric; Lavergne, Sébastien; Schwörer, Christoph; Theurillat, Jean-Paul; Heintzman, Peter D.; Wangensteen, Owen S.; Tinner, Willy; Rey, Fabian; Heer, Martina; Rutzer, Astrid; Walsh, Kevin; Lammers, Youri; Brown, Antony G.; Goslar, Tomasz; Rijal, Dilli P.; Karger, Dirk N.; Pellissier, Loïc; Heiri, Oliver (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-04)
      The European Alps are highly rich in species, but their future may be threatened by ongoing changes in human land use and climate. Here, we reconstructed vegetation, temperature, human impact and livestock over the past ~12,000 years from Lake Sulsseewli, based on sedimentary ancient plant and mammal DNA, pollen, spores, chironomids, and microcharcoal. We assembled a highly-complete local DNA ...

    • Holocene floristic diversity and richness in northeast Norway revealed by sedimentary ancient DNA (sedaDNA) and pollen 

      Clarke, Charlotte; Edwards, Mary Elizabeth; Brown, Antony Gavin; Gielly, Ludovic; Lammers, Youri; Heintzman, Peter D.; Murguzur, Francisco Javier Ancin; Bråthen, Kari Anne; Goslar, Tomasz; Alsos, Inger Greve (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-30)
      We present a Holocene record of floristic diversity and environmental change for the central Varanger Peninsula, Finnmark, based on ancient DNA extracted from the sediments of a small lake (<i>sed</i>aDNA). The record covers the period c. 10 700 to 3300 cal. a BP and is complemented by pollen data. Measures of species richness, sample evenness and beta diversity were calculated based on <i>sed</i>aDNA ...

    • Last Glacial Maximum environmental conditions at Andøya, northern Norway; evidence for a northern ice-edge ecological “hotspot” 

      Alsos, Inger Greve; Sjögren, Per; Brown, Antony G.; Gielly, Ludovic; Merke, Marie Kristine Føreid; Paus, Aage; Lammers, Youri; Edwards, Mary E.; Alm, Torbjørn; Leng, Melanie; Goslar, Tomasz; Langdon, Catherine T.; Bakke, Jostein; van der Bilt, Willem G.M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-05)
      Andøya on the NW coast of Norway is a key site for understanding the Last Glacial Maximum (LGM) in northern Europe. Controversy has arisen concerning the local conditions, especially about the timing and extent of local glacial cover, maximum July temperatures and whether pine and/or spruce could have grown there. We reviewed all existing data and add newly analysed ancient sedimentary DNA ...

    • 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 ...
