      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 ...

    • Uncovering neutral and adaptive genomic differentiation among European perch with brackish water and freshwater origin in the western Baltic Sea region 

      Skovrind, Mikkel; Pacheco, George; Christensen, Emil Aputsiaq Flindt; Gopalakrishnan, Shyam; Fietz, Katharina; Holm-Hansen, Tore Hejl; Vieira, Filipe Garrett; Krag, Marcus Anders; Carl, Henrik; Gilbert, Marcus Thomas Pius; Olsen, Morten Tange; Møller, Peter Daniel Rask (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-13)
      Environmental variation across the range of wild species can lead to local adaptations. The Baltic Sea was formed when the Fenno-Scandian ice sheet retreated around 12 thousand years ago, creating a new brackish water habitat colonised by both marine and freshwater fish species. The European perch (Perca fluviatilis) is a predatory freshwater fish with a large geographical distribution across ...
