      1. Due to globalisation, trade and transport, the spread of alien species is increasing dramatically. Some alien species become ecologically harmful by threatening native biota. This can lead to irreversible changes in ...
    • Conserving on the edge: genetic variation and structure in Northern populations of the endangered plant Dracocephalum ruyschiana L. (Lamiaceae) 

      Kyrkjeeide, Magni Olsen; Westergaard, Kristine Bakke; Kleven, Oddmund; Evju, Marianne; Endrestøl, Anders; Brandrud, Marie Kristine; Stabbetorp, Odd Egil (Peer reviewed; Journal article, 2020)
      Loss of biodiversity is accelerating, including the loss of genetic diversity. Conservation of small, isolated populations may be important, as they can provide valuable contributions to overall genetic variation and ...
    • 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 (Peer reviewed; Journal article, 2015)
      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 ...
    • Non-native vascular flora of the Arctic: Taxonomic richness, distribution and pathways 

      Wasowicz, Pawel; Sennikov, Alexander N.; Westergaard, Kristine Bakke; Spellman, Katie; Carlson, Matthew; Gillespie, Lynn J.; Saarela, Jeffery M.; Seefeldt, Steven S.; Bennett, Bruce; Bay, Christian; Ickert-Bond, Stefanie; Väre, Henry (Journal article, 2020)
      We present a comprehensive list of non-native vascular plants known from the Arctic, explore their geographic distribution, analyze the extent of naturalization and invasion among 23 subregions of the Arctic, and examine ...
    • Population genomic evidence for plant glacial survival in Scandinavia 

      Westergaard, Kristine Bakke; Zemp, Niklaus; Bruederle, Leo P.; Stenøien, Hans K.; Widmer, Alex; Fior, Simone (Journal article; Peer reviewed, 2019)
      Quaternary glaciations have played a major role in shaping the genetic diversity and distribution of plant species. Strong palaeoecological and genetic evidence supports a postglacial recolonization of most plant species ...
