    • 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) ...

    • 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). ...

    • A National Scale “BioBlitz” Using Citizen Science and eDNA Metabarcoding for Monitoring Coastal Marine Fish 

      Agersnap, Sune; Sigsgaard, Eva Egelyng; Jensen, Mads Reinholdt; Ávila, Marcelo De Paula; Carl, Henrik; Møller, Peter Rask; Krøs, Simon Leed; Knudsen, Steen Wilhelm; Wisz, Mary S.; Thomsen, Philip Francis (Peer reviewed; Journal article, 2022)
      Marine biodiversity is threatened by human activities. To understand the changes happening in aquatic ecosystems and to inform management, detailed, synoptic monitoring of biodiversity across large spatial extents is needed. ...

    • Seasonal turnover in community composition of stream-associated macroinvertebrates inferred from freshwater environmental DNA metabarcoding 

      Jensen, Mads Reinholdt; Egelyng Sigsgaard, Eva; Agersnap, Sune; Rasmussen, Jes Jessen; Baattrup-Pedersen, Annette; Wiberg-Larsen, Peter; Thomsen, Philip Francis (Peer reviewed; Journal article, 2021)
      Macroinvertebrate communities are crucial for biodiversity monitoring and assessment of ecological status in stream ecosystems. However, traditional monitoring approaches require intensive sampling and rely on invasive ...

    • Short-term temporal variation of coastal marine eDNA 

      Jensen, Mads Reinholdt; Sigsgaard, Eva Egelyng; Ávila, Marcelo De Paula; Agersnap, Sune; Brenner-Larsen, William; Sengupta, Mita Eva; Xing, Yingchun; Krag, Marcus Anders; Knudsen, Steen Wilhelm; Carl, Henrik; Møller, Peter Daniel Rask; Thomsen, Philip Francis (Peer reviewed; Journal article, 2022)
      Temporal variation in eDNA signals is increasingly explored for understanding community ecology in aquatic habitats. Seasonal changes have been addressed using eDNA sampling, but very little is known regarding short-term ...
