    • Gatekeepers to the effects of climate warming? Niche construction restricts plant community changes along a temperature gradient 

      Bråthen, Kari Anne; Gonzalez, Victoria; Yoccoz, Nigel Gilles (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-20)
      Organisms that modify the environment (niche constructors) are likely candidates to mediate the effects of climate warming. Here we assess tundra plant community changes along a temperature gradient and how these are modified in the presence of the common allelopathic dwarf shrub Empetrum nigrum and the large herbivore Rangifer tarandus. 2 We developed a structural equation model based on data ...

    • High resistance to climatic variability in a dominant tundra shrub species 

      Gonzalez, Victoria; Moriana Armendariz, Mikel; Hagen, Snorre; Lindgård, Bente; Reiersen, Rigmor; Bråthen, Kari Anne (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-05)
      Climate change is modifying temperature and precipitation regimes across all seasons in northern ecosystems. Summer temperatures are higher, growing seasons extend into spring and fall and snow cover conditions are more variable during winter. The resistance of dominant tundra species to these season-specific changes, with each season potentially having contrasting effects on their growth and survival, ...

    • Niche construction mediates climate effects on recovery of tundra heathlands after extreme event 

      Gonzalez, Victoria; Lindgård, Bente; Reiersen, Rigmor; Hagen, Snorre; Bråthen, Kari Anne (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-04)
      Climate change is expected to increase the frequency and intensity of extreme events in northern ecosystems. The outcome of these events across the landscape, might be mediated by species effects, such as niche construction, with likely consequences on vegetation resilience. To test this hypothesis, we simulated an extreme event by removing aboveground vegetation in tundra heathlands dominated by ...

    • Studying phenological phenomena in subarctic biomes with international school pupils as citizen scientists 

      Klutsch, Cornelya; Aspholm, Paul Eric; Polikarpova, Natalia; Veisblium, Olga; Bjørn, Tor-Arne; Wikan, Anne; Gonzalez, Victoria; Hagen, Snorre B. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-30)
      Citizen science can facilitate in‐depth learning for pupils and students, contribute to scientific research, and permit civic participation. Here, we describe the development of the transnational school‐based citizen science project <i>Phenology of the North Calotte</i>. Its primary goal is to introduce pupils (age 12–15; grades 7–10) in northern Norway, Russia, and Finland to the local and global ...
