      Alsos, Inger Greve; Rijal, Dilli Prasad; Ehrich, Dorothee; Karger, Dirk Nikolaus; Yoccoz, Nigel; Heintzman, Peter D.; Brown, Antony; Lammers, Youri; Pellissier, Loïc; Alm, Torbjørn; Bråthen, Kari Anne; Coissac, Eric; Merkel, Marie Føreid; Alberti, Adriana; Denoeud, France; Bakke, Jostein (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-28)
      What drives ecosystem buildup, diversity, and stability? We assess species arrival and ecosystem changes across 16 millennia by combining regional-scale plant sedimentary ancient DNA from Fennoscandia with near-complete DNA and trait databases. We show that postglacial arrival time varies within and between plant growth forms. Further, arrival times were mainly predicted by adaptation to temperature, ...

    • Sedimentary ancient DNA reveals local vegetation changes driven by glacial activity and climate. 

      Elliott, Lucas Dane; Rijal, Dilli Prasad; Brown, Antony; Bakke, Jostein; Topstad, Lasse; Heintzman, Peter D.; Alsos, Inger Greve (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-07)
      Disentangling the effects of glaciers and climate on vegetation is complicated by the confounding role that climate plays in both systems. We reconstructed changes in vegetation occurring over the Holocene at Jøkelvatnet, a lake located directly downstream from the Langfjordjøkel glacier in northern Norway. We used a sedimentary ancient DNA (sedaDNA) metabarcoding dataset of 38 samples from a ...
