    • Characterization of 14 microsatellite markers for Silene acaulis (Caryophyllaceae) 

      Müller, Eike; Hlavackova, Iva; Svoen, Mildrid Elvik; Alsos, Inger Greve; Eidesen, Pernille Bronken (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-09-08)
      Premise of the study: Fifty candidate microsatellite markers, generated using 454 shotgun sequencing, were tested for the widespread arctic/alpine herb Silene acaulis (Caryophyllaceae). Methods and Results: Fourteen out of 50 markers resulted in polymorphic products with profiles that enabled interpretation. The numbers of alleles per locus ranged from two to six, and the expected heterozygosity ...

    • Frequency of local, regional, and long-distance dispersal of diploid and tetraploid Saxifraga oppositifolia (Saxifragaceae) to Arctic glacier forelands 

      Müller, Eike; Eidesen, Pernille Bronken; Ehrich, Dorothee; Alsos, Inger Greve (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Climate change forces many species to migrate. Empirical small-scale data on migration and colonization in the Arctic are scarce. Retreating glaciers provide new territory for cold-adapted plant species, but the genetic consequences depend on dispersal distances and frequencies. We estimated local, regional, and long-distance dispersal frequencies, as well as their effect on levels of genetic ...

    • Germinating seeds or bulbils in 87 of 113 tested Arctic species indicate potential for ex situ seed bank storage 

      Alsos, Inger Greve; Müller, Eike; Eidesen, Pernille Bronken (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Arctic plant species are expected to lose range due to climate change. One approach to preserve the genetic and species diversity for the future is to store propagules in seed vaults. However, germinability of seeds is assumed to be low for Arctic species. We evaluated ex situ storage potential of 113 of the 161 native angiosperms of Svalbard by studying seed ripening and germination. Seeds or bulbils ...

    • Tetraploids do not form cushions: association of ploidy level, growth form and ecology in the High Arctic Saxifraga oppositifolia L. s. lat. (Saxifragaceae) in Svalbard 

      Eidesen, Pernille Bronken; Müller, Eike; Lettner, Christian; Alsos, Inger Greve; Bender, Morgan; Kristiansen, Martin; Peeters, Bart; Postma, Froukje; Verweij, Koen Frans (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Saxifraga oppositifolia L. is a common circumpolar plant species that displays considerable morphological and genetic variation throughout its range. It is mainly diploid, but tetraploids are reported from several regions. The growth form varies from prostate to cushion-shaped, and the plant thrives in wet snow beds as well as on dry ridges. This variation has triggered the curiosity of ...
