      GrassPlot is a collaborative vegetation-plot database organised by the Eurasian Dry Grassland Group (EDGG) and listed in the Global Index of Vegetation-Plot Databases (GIVD ID EU-00-003). GrassPlot collects plot records ...
    • Impact of climate change on alpine vegetation of mountain summits in Norway 

      Vanneste, Thomas; Michelsen, Ottar; Graae, Bente Jessen; Kyrkjeeide, Magni Olsen; Holien, Håkon; Hassel, Kristian; Lindmo, Sigrid; Kapás, Rozália Erzsebet; De Frenne, Pieter (Journal article; Peer reviewed, 2017)
      Climate change is affecting the composition and functioning of ecosystems across the globe. Mountain ecosystems are particularly sensitive to climate warming since their biota is generally limited by low temperatures. ...
    • Is interspecific gene flow and speciation in peatmosses (Sphagnum) constrained by phylogenetic relationship and life-history traits? 

      Meleshko, Olena; Stenøien, Hans K.; Speed, James David Mervyn; Flatberg, Kjell Ivar; Kyrkjeeide, Magni Olsen; Hassel, Kristian (Journal article; Peer reviewed, 2018)
      Peatmosses are interesting for studies of speciation processes not only because of their frequent hybridization and recent diversification, but also their phenotypic diversity, ecological importance and ancient history. ...
    • Long-distance dispersal and barriers shape genetic structure of peatmosses (Sphagnum) across the Northern Hemisphere 

      Kyrkjeeide, Magni Olsen; Hassel, Kristian; Flatberg, Kjell Ivar; Shaw, A. Jonathan; Brochmann, Christian; Stenøien, Hans K. (Journal article; Peer reviewed, 2016)
      Aim Disjunctly distributed peatmosses (Sphagnum) have been found to exhibit little genetic structure over regional and intercontinental scales, mainly caused by high ability for transoceanic long-distance dispersal. ...
