      Andersen, Jesper Harbo; Kallenbach, Emilie; Kjeldgaard, Mathias Brink; Knudsen, Steen Wilhelm; Eikrem, Wenche; Fagerli, Camilla With; Oug, Eivind; Dale, Trine; Thaulow, Jens; Gitmark, Janne Kim; Hobæk, Anders; Green, Norman Whitaker; Hesselsøe, Martin; Støttrup, Josianne; Kuhn, Jesper; Bekkevold, Dorte; Jacobsen, Lars Magnus Wulf; Møller, Peter Rask; Olesen, Christian Aakjær; Carl, Henrik; Stuer-Lauridsen, Frank (NIVA-rapport;7769-2022, Research report, 2022)
      We report the first ever nation-wide study of the occurrence of non-indigenous species in Danish harbours. The sampling was car-ried out using both conventional and biomolecular methods (eDNA). In total, 16 harbours were ...
    • Development of species-specific eDNA-based test systems for monitoring of non-indigenous species in Danish marine waters 

      Andersen, Jesper Harbo; Kallenbach, Emilie; Thaulow, Jens; Hesselsøe, Martin; Bekkevold, Dorte; Hansen, Brian Klitgaard; Jacobsen, Lars Magnus Wulf; Olesen, Christian Aakjaer; Møller, Peter Rask; Knudsen, Steen W. (NIVA-rapport;7204, Research report, 2018)
      The MONIS 3 project reports the development of 22 species-specific eDNA-based test systems for monitoring and mapping of the occurrence of non-indigenous species in Danish marine waters. The development has been undertaken ...
    • Monitoring of environmental DNA from nonindigenous species of algae, dinoflagellates and animals in the North East Atlantic 

      Knudsen, Steen Wilhelm; Hesselsøe, Martin; Thaulow, Jens; Agersnap, Sune; Hansen, Brian Klitgaard; Jacobsen, Magnus Wulff; Bekkevold, Dorte; Jensen, Søren K.S.; Møller, Peter Rask; Andersen, Jesper H. (Peer reviewed; Journal article, 2022)
      Monitoring the distribution of marine nonindigenous species is a challenging task. To support this monitoring, we developed and validated the specificity of 12 primer-probe assays for detection of environmental DNA (eDNA) ...
    • Remote, autonomous real‑time monitoring of environmental DNA from commercial fish 

      Hansen, Brian K; Jacobsen, Magnus W; Middelboe, Anne Lise; Preston, Christina M.; Marin III, Roman; Bekkevold, Dorte; Knudsen, Steen Wilhelm; Møller, Peter R.; Nielsen, Einar E (Peer reviewed; Journal article, 2020)
      Environmental DNA (eDNA) is increasingly used for monitoring marine organisms; however, offshore sampling and time lag from sampling to results remain problematic. In order to overcome these challenges a robotic sampler, ...
    • Steps toward nation-wide monitoring of non-indigenous species in Danish marine waters under the Marine Strategy Framework Directive 

      Andersen, Jesper Harbo; Kallenbach, Emilie; Hesselsøe, Martin; Knudsen, Steen W.; Møller, Peter Rask; Bekkevold, Dorte; Hansen, Brian Klitgaard; Thaulow, Jens (NIVA-rapport;7022, Research report, 2016)
      This report is the outcome of MONIS 2 – or in full, “Monitoring of Non-Indigenous Species in Danish Marine Water, phase 2” – and includes three deliverable: (1) a national Target Species List including 50 species, (2) a ...
    • Tekniske anvisninger for eDNA-baseret overvågning af ikke-hjemmehørende marine arter 

      Knudsen, Steen Wilhelm; Andersen, Jesper Harbo; Bekkevold, Dorte; Hesselsøe, Martin; Jensen, Søren K S; Møller, Peter Rask (NIVA-rapport;7455, Research report, 2020)
      Disse tekniske anvisninger er en revideret udgave af de ansvisninger, der tidligere er udarbejdet for Miljøstyrelsen og publiceret vinteren 2017/2018. De reviderede tekniske anvisninger indeholder en detaljeret protokol ...
