      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 freshwater crayfish 

      Knudsen, Steen Wilhelm; Agersnap, Sune; Møller, Peter Rask; Andersen, Jesper Harbo (NIVA-rapport;7447, Research report, 2019)
      This MONIS 5 report focuses on freshwater crayfish and was funded by the Danish Environmental Protection Agency. The aim of the present study was to develop species-specific systems for tracking environmental DNA (eDNA) ...

    • Development of species-specific eDNA-based test systems for monitoring of non-indigenous Decapoda in Danish marine waters 

      Knudsen, Steen Wilhelm; Møller, Peter Rask (NIVA-rapport;7544, Research report, 2020)
      We report the development of seven eDNA-based species-specific test systems for monitoring of marine Decapoda in Danish marine waters. The seven species are 1) Callinectes sapidus (blå svømmekrabbe), 2) Eriocheir sinensis ...

    • Development of species-specific eDNA-based test systems for monitoring of non-indigenous species in Danish marine waters

      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 ...

    • Ikke-hjemmehørende arter i marine områder 

      Andersen, Jesper Harbo; Knudsen, Steen Wilhelm; Murray, Ciaran Joseph; Carl, Henrik; Møller, Peter Rask; Hesselsøe, Martin (NIVA-rapport;7658, Research report, 2021)
      Denne rapport omhandler ikke-hjemmehørende arter i de danske farvande og består af to dele. Den første vedrører en opdate-ring af den nationale liste over ikke-hjemmhørende arter i de danske farvande – også kaldet NIS-listen. ...

    • Monitoring a Norwegian freshwater crayfish tragedy: eDNA snapshots of invasion, infection and extinction 

      Strand, David; Johnsen, Stein Ivar; Rusch, Johannes; Agersnap, Sune; Larsen, William Brenner; Knudsen, Steen Wilhelm; Møller, Peter Rask; Vrålstad, Trude (Journal article; Peer reviewed, 2019)
      1. The European noble crayfish Astacus astacus is threatened by crayfish plague caused by the oomycete Aphanomyces astaci, which is spread by the invasive North American crayfish (e.g. signal crayfish Pacifastacus leniusculus). ...

    • Monitoring of environmental DNA from nonindigenous species of algae, dinoflagellates and animals in the North East Atlantic
