    • DNA Metabarcoding of Preservative Ethanol Reveals Changes in Invertebrate Community Composition Following Rotenone Treatment 

      Kjærstad, Gaute; Majaneva, Markus; Falahati-Anbaran, Mohsen; Topstad, Lasse; Finstad, Anders Gravbrøt; Arnekleiv, Jo Vegar; Ekrem, Torbjørn (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-01)
      The botanical compound rotenone is extensively used to eradicate populations and reduce the negative impacts of freshwater invasive animals. The method is controversial as non-target organisms often are negatively affected, but these effects are highly variable among taxa and may be difficult to monitor on species-level as many invertebrates are challenging or costly to identify using morphology. ...

      Guidetti, Roberto; Jönsson, K. Ingemar; Kaczmarek, Łukasz; Meier, Terje; Speed, James David Mervyn; Prestø, Tommy; Stur, Elisabeth; Topstad, Lasse; Cesari, Michele; Roszkowska, Milena; Zawierucha, Krzysztof; Hassel, Kristian; Ekrem, Torbjørn (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-26)
      Tardigrades are common in many terrestrial environments and habitats. Although little is known on their ecological preferences, previous studies found diversity and community composition significantly affected by various variables. This study associated tardigrade species’ records with climatic variables, forest type, and substrate categories exploring tardigrade diversity and species communities ...
