      1. Due to globalisation, trade and transport, the spread of alien species is increasing dramatically. Some alien species become ecologically harmful by threatening native biota. This can lead to irreversible changes in ...

    • DNA Metabarcoding of Preservative Ethanol Reveals Changes in Invertebrate Community Composition Following Rotenone Treatment 

      Kjærstad, Gaute; Majaneva, Markus; Falahati-Anbaran, Mohsen; Topstad, Lasse; Finstad, Anders Gravbrøt; Arnekleiv, Jo Vegar; Ekrem, Torbjørn (Peer reviewed; Journal article, 2022)
      The botanical compound rotenone is extensively used to eradicate populations and reduce the negative impacts of freshwater invasive animals. The method is controversial as non target organisms often are negatively affected, ...

    • Hydropower impacts on reservoir fish populations are modified by environmental variation 

      Eloranta, Antti; Finstad, Anders Gravbrøt; Helland, Ingeborg Palm; Ugedal, Ola; Power, Michael (Journal article; Peer reviewed, 2018)
      Global transition towards renewable energy production has increased the demand for newand more flexible hydropower operations. Beforemanagement and stakeholders can make informed choices on potential mitigations, it is ...

    • Ice-dependent winter survival of juvenile Atlantic salmon 

      Hedger, Richard David; Næsje, Tor; Fiske, Peder; Ugedal, Ola; Finstad, Anders Gravbrøt; Thorstad, Eva Bonsak (Peer reviewed; Journal article, 2013)
      Changes in snow and ice conditions are some of the most distinctive impactsof global warming in cold temperate and Arctic regions, altering the environ-ment during a critical period for survival for most animals. Laboratories ...

      Eloranta, Antti; Kjærstad, Gaute; Power, Michael; Lakka, Hanna-Kaisa; Arnekleiv, Jo Vegar; Finstad, Anders Gravbrøt (Peer reviewed; Journal article, 2022)
      Chemical eradication of non-native species has become a widely used method to mitigate the potential negative im- pacts of altered competitive or predatory dynamics on biodiversity and natural ecosystem processes. However, ...

    • Interactions between local population density and limited habitat resources determine movements of juvenile Atlantic salmon 

      Teichert, Maxim; Foldvik, Anders; Einum, Sigurd; Finstad, Anders Gravbrøt; Forseth, Torbjørn; Ugedal, Ola (Journal article; Peer reviewed, 2017)
      Competition for limited resources and the resulting density-dependent processes are key factors in driving stream salmonid population dynamics. Here we test for the combined effects of density and shelter availability on ...
