    • Environmental DNA metabarcoding reveals seasonal and spatial variation in the vertebrate fauna of Ilulissat Icefjord, Greenland 

      Schiøtt, Sascha; Jensen, Mads Reinholdt; Sigsgaard, Eva Egelyng; Møller, Peter Daniel Rask; Thomsen, Philip Francis; Rysgaard, Søren; de Paula Avila, Marcelo (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-23)
      Ilulissat Icefjord in Greenland is experiencing the effects of climate change, with the Sermeq Kujalleq glacier being one of the fastest-moving and most productive ice streams in Greenland. This is likely affecting the distribution of species in the fjord, including those important to local fisheries. Due to heavy ice conditions, few studies on environmental and ecological conditions exist from ...

    • Holistic monitoring of freshwater and terrestrial vertebrates by camera trapping and environmental DNA 

      Holm, Anne Marie Rubæk; Knudsen, Steen Wilhelm; Månsson, Malene; Pedersen, Ditte Elmgreen; Nordfoss, Pauli Holm; Johansson, Daniel Klingberg; Gramsbergen, Marthe; Havmøller, Rasmus Worsøe; Sigsgaard, Eva Egelyng; Thomsen, Philip Francis; Olsen, Morten Tange; Møller, Peter Daniel Rask (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-20)
      The anthropogenic impact on the world's ecosystems is severe and the need for non-invasive, cost-effective tools for monitoring and understanding those impacts are therefore urgent. Here, we combine two such methods in a comprehensive multi-year study; camera trapping (CT) and analysis of environmental DNA (eDNA), in river marginal zones of a temperate, wetland Nature Park in Denmark. CT was ...

    • 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 (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-28)
      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. Such monitoring is challenging due to the time, cost, and specialized skills that this typically requires. In an unprecedented study, we combined citizen science with eDNA ...

    • 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 (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-23)
      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 temporal variation that spans hours to days. To address this, we filtered marine water samples from a single coastal site in Denmark every hour for 32 h. We used metabarcoding to ...
