    • Ancient sedimentary DNA shows rapid post-glacial colonisation of Iceland followed by relatively stable vegetation until the Norse settlement (Landnám) AD 870 

      Alsos, Inger Greve; Lammers, Youri; Kjellman, Sofia Elisabeth; Merkel, Marie Føreid; Bender, Emma Marie; Rouillard, Alexandra; Erlendsson, Egill; Gudmundsdottir, Esther Ruth; Benediktsson, Ívar Örn; Farnsworth, Wesley Randall; Brynjólfsson, Skafti; Gísladóttir, Guðrún; Eddudóttir, Sigrún Dögg; Schomacker, Anders (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-08)
      Understanding patterns of colonisation is important for explaining both the distribution of single species and anticipating how ecosystems may respond to global warming. Insular flora may be especially vulnerable because oceans represent severe dispersal barriers. Here we analyse two lake sediment cores from Iceland for ancient sedimentary DNA to infer patterns of colonisation and Holocene vegetation ...

    • Submarginal drumlin formation and late Holocene history of Fláajökull, southeast Iceland 

      Jónsson, Sverrir A.; Benediktsson, Ívar Örn; Ingólfsson, Ólafur; Schomacker, Anders; Bergsdóttir, Helga Lucia; Jacobson Jr., William R.; Linderson, Hans (Journal article; Tidsskriftartikkel; Peer reviewed, 2016)
      Fláajökull is a non-surging outlet glacier draining the south-eastern part of the Vatnajökull, southeast Iceland. Fláajökull was stationary or advanced slightly between 1966 and 1995 and formed a prominent end moraine. Glacial retreat since then has revealed a cluster of 15 drumlins. This study focuses on the morphology and sedimentology of the drumlins. They are 100–600 m long, 40–130 m wide, and ...
