    • 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, ...

    • Interfering with neighbouring communities: Allelopathy astray in the tundra delays seedling development 

      Pilsbacher, Anna Katharina; Lindgård, Bente; Reiersen, Rigmor; González, Victoria T.; Bråthen, Kari Anne (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-06)
      <ol> <li>Altered species composition caused by environmental and climatic change can affect the transfer of plant residues among communities. Whereas transferred residues are typically considered a resource in recipient systems, residues of allelopathic species may instead cause interference.</li> <li>Evergreen dwarf shrubs, specifically the allelopathic species Empetrum nigrum are increasing ...

    • 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 ...

    • Prevention of Marine Biofouling Using the Natural Allelopathic Compound Batatasin-III and Synthetic Analogues 

      Moodie, Lindon; Trepos, Rozenn; Cervin, Gunnar; Bråthen, Kari Anne; Lindgård, Bente; Reiersen, Rigmor; Cahill, Patrick; Pavia, Henrik; Hellio, Claire; Svenson, Johan (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-21)
      The current study reports the first comprehensive evaluation of a class of allelopathic terrestrial natural products as antifoulants in a marine setting. To investigate the antifouling potential of the natural dihydrostilbene scaffold, a library of 22 synthetic dihydrostilbenes with varying substitution patterns, many of which occur naturally in terrestrial plants, were prepared and assessed for ...
