    • Circumpolar Arctic vegetation: a hierarchic review and roadmap toward an internationally consistent approach to survey, archive and classify tundra plot data 

      Walker, D. A.; Daniels, F.J.A.; Alsos, Inger Greve; Bhatt, U S; Breen, A L; Buchhorn, M; Bultmann, H; Druckenmiller, L A; Edwards, M E; Ehrich, Dorothee; Epstein, Howard E.; Gould, W.A.; Ims, Rolf Anker; Meltofte, H; Raynolds, M. K.; Sibik, J; Talbot, SS; Webber, P. J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-05-10)
      Satellite-derived remote-sensing products are providing a modern circumpolar perspective of Arctic vegetation and its changes, but this new view is dependent on a long heritage of ground-based observations in the Arctic. Several products of the Conservation of Arctic Flora and Fauna are key to our current understanding.Wereview aspects of the PanArctic Flora, the Circumpolar Arctic Vegetation ...
    • Long-distance plant dispersal to North Atlantic islands: colonization routes and founder effect 

      Alsos, Inger Greve; Ehrich, Dorothee; Eidesen, Pernille Bronken; Solstad, Heidi Merethe; Westergaard, Kristine Bakke; Schonswetter, Peter; Tribsch, Andreas; Birkeland, Siri; Elven, Reidar; Brochmann, Christian (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-04-15)
      Long-distance dispersal (LDD) processes influence the founder effect on islands.We use genetic data for 25 Atlantic species and similarities among regional floras to analyse colonization, and test whether the genetic founder effect on five islands is associated with dispersal distance, island size and species traits. Most species colonized postglacially via multiple dispersal events from several ...
    • The role of sea ice for vascular plant dispersal in the Arctic 

      Alsos, Inger Greve; Ehrich, Dorothee; Seidenkrantz, Marit-Solveig; Bennike, Ole; Kirchhefer, Andreas; Geirsdottir, Aslaug (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-09)
      Sea ice has been suggested to be an important factor for dispersal of vascular plants in the Arctic. To assess its role for postglacial colonization in the North Atlantic region, we compiled data on the first Late Glacial to Holocene occurrence of vascular plant species in East Greenland, Iceland, the Faroe Islands and Svalbard. For each record, we reconstructed likely past dispersal events ...
