      The relative contribution of bryophytes to plant diversity, primary productivity, and ecosystem functioning increases towards colder climates. Bryophytes respond to environmental changes at the species level, but because ...
    • Coastal heathland vegetation is surprisingly resistant to experimental drought across successional stages and latitude 

      Haugum, Siri Vatsø; Thorvaldsen, Pål; Vandvik, Vigdis; Velle, Liv Guri (Journal article; Peer reviewed, 2021)
      In the last decade, several major dwarf-shrub dieback events have occurred in northern European coastal heathlands. These dieback events occur after extended periods with sub-zero temperatures under snow-free conditions ...
    • The effect of grazing and hiking on the elevational range shift of vascular plant species in the Scandes during recent decades 

      Haugum, Siri Vatsø (Master thesis, 2016-06-01)
      Resurvey of historical plant distribution data can provide valuable information about how plant communities have changed, a topic which is of great interest due to recent decades of climate and land use change. Range shifts ...
    • Germination and seedling growth of Calluna vulgaris is sensitive to regional climate, heathland succession, and drought 

      Birkeli, Kristine; Gya, Ragnhild; Haugum, Siri Vatsø; Velle, Liv Guri; Vandvik, Vigdis (Journal article; Peer reviewed, 2023)
      The coastal heathlands of Northwest Europe are highly valued cultural landscapes, that are critically endangered due to land use and climatic changes, such as increased frequency and severity of drought events. Our study ...

      Research in global change ecology relies heavily on global climatic grids derived from estimates of air temperature in open areas at around 2 m above the ground. These climatic grids do not reflect conditions below vegetation ...
    • Intraspecific trait variability is a key feature underlying high Arctic plant community resistance to climate warming 

      Jonsdottir, Ingibjørg; Halbritter Rechsteiner, Aud Helen; Christiansen, Casper Tai; Althuizen, Inge; Haugum, Siri Vatsø; Henn, Jonathan J.; Björnsdóttir, Katrín; Maitner, Brian Salvin; Malhi, Yadvinder; Michaletz, Sean T.; Roos, Ruben Erik; Klanderud, Kari; Lee, Hanna; Enquist, Brian J.; Vandvik, Vigdis (Journal article; Peer reviewed, 2022)
      In the high Arctic, plant community species composition generally responds slowly to climate warming, whereas less is known about the community functional trait responses and consequences for ecosystem functioning. The ...
    • Land-use and climate impacts on drought resistance and resilience in coastal heathland ecosystems 

      Haugum, Siri Vatsø (Doctoral thesis, 2021-12-15)
      Background: Coastal heathlands of north-western Europe are semi-natural landscapes of high conservation value. These are ancient and historically widespread landscapes, but anthropogenic land-use and climate change are now ...
