    • 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 ...
    • Lake sedimentary DNA accurately records 20th Century introductions of exotic conifers in Scotland 

      Sjøgren, Per Johan; Edwards, Mary Elizabeth; Gielly, Ludovic; Langdon, Cathrine; Croudace, I.W.; Merkel, Marie Kristine Føreid; Thierry, Fonville; Alsos, Inger Greve (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-09-28)
      Sedimentary DNA (sedDNA) has recently emerged as a new proxy for reconstructing past vegetation, but its taphonomy, source area and representation biases need better assessment. We investigated how sedDNA in recent sediments of two small Scottish lakes reflects a major vegetation change, using well-documented 20th Century plantations of exotic conifers as an experimental system. We used next-generation ...
    • Plant DNA in sediments: to which degree do they represent the flora? 

      Alsos, Inger Greve; Coissac, Eric; Edwards, Mary E.; Merkel, Marie Kristine Føreid; Gielly, Ludovic; Sjögren, Per; Taberlet, Pierre; Yoccoz, Nigel Gilles (Conference object; Konferansebidrag, 2015-05)
    • Plant DNA metabarcoding of lake sediments: How does it represent the contemporary vegetation 

      Alsos, Inger Greve; Lammers, Youri; Yoccoz, Nigel Gilles; Jørgensen, Tina; Sjögren, Per; Gielly, Ludovic; Edwards, Mary E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-17)
      Metabarcoding of lake sediments have been shown to reveal current and past biodiversity, but little is known about the degree to which taxa growing in the vegetation are represented in environmental DNA (eDNA) records. We analysed composition of lake and catchment vegetation and vascular plant eDNA at 11 lakes in northern Norway. Out of 489 records of taxa growing within 2 m from the lake shore, ...
    • Sedimentary ancient DNA from Lake Skartjørna, Svalbard: Assessing the resilience of arctic flora to Holocene climate change 

      Alsos, Inger Greve; Sjögren, Per Johan E.; Edwards, Mary E.; Landvik, Jon Y.; Gielly, Ludovic; Forwick, Matthias; Coissac, Eric; Brown, Antony G; Jakobsen, Leif Vidar; Merkel, Marie Kristine Føreid; Pedersen, Mikkel Winter (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-11-11)
