• Niche construction across climate gradients: the case of Empetrum nigrum in tundra plant communities 

      Tevendale, Victoria González (Doctoral thesis; Doktorgradsavhandling, 2018-06-08)
      Here we studied at relevant spatial and temporal scales, how the evergreen dwarf shrub Empetrum nigrum, through its niche constructor ability, affects tundra plant communities along climatic gradients. Empetrum is a common dwarf shrub which is particularly abundant in many tundra ecosystems. As a niche constructor is has strong influence on many ecosystem processes and its direct effects can last ...
    • Reindeer grazing history effects on plant recruitment and life history traits from the germinable seed bank 

      Tevendale, Victoria González (Master thesis; Mastergradsoppgave, 2006-03-27)
      Seed banks represent a source from which new vegetation may quickly arise if the existing stand is disturbed. It is increasingly discussed that reindeer grazing modifies the seed banks in northern ecosystems. However no large-scale studies have been carried out to support this hypothesis. Because reindeer could constitute a selective pressure on vegetation recruitment, the present study investigated ...
