    • Allochthonous Allelopathy. Effects of Empetrum nigrum chemical interference on plant development 

      Pilsbacher, Anna Katharina (Master thesis; Mastergradsoppgave, 2016-05-20)
      The dwafshrub Empetrum nigrum uses phenolic compounds exuded by its leaves to depress the germination and growth of its surroundings. The allelopathic effect has, only been studied in areas immediately surrounding the plant (autochthonous allelopathy) but not in an open system apptoach that takes into account that a multitude of EMpetrum nigrum leaves get introduced into new environments through ...

    • Disappearing green: Shrubs decline and bryophytes increase with nine years of increased snow accumulation in the High Arctic 

      Cooper, Elisabeth J.; Little, Chelsea J.; Pilsbacher, Anna Katharina; Mörsdorf, Martin Alfons (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-25)
      <i>Question</i> - How does increased snow depth affect plant community composition of High Arctic tundra, and can the Normalized Differential Vegetation Index (NDVI) detect induced changes?<p><p> <i>Location</i> - Adventdalen, Spitsbergen, Svalbard (78°10′ N, 16°04′ E).<p><p> <i>Methods</i> - We manipulated snow depth on the tundra using fences, resulting in <i>Deep, Medium</i>, and ...

    • 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 ...

    • Prepositional Phrase Attachment Ambiguities in German. A Cross-Dialectal Experimental Study 

      Pilsbacher, Anna Katharina (Master thesis; Mastergradsoppgave, 2018-05-15)
      This thesis addresses the production and perception of sentences with ambiguous prepositional phrase attachment in Standard German. In the first part of the study, an informed native speaker produced prosodically disambiguated sentences, which were analysed acoustically for disambiguation cues. In the second part, these sentences were then presented in a perception test where respondents were asked ...
