    • Determinants of parasite distribution in Arctic charr populations: catchment structure versus dispersal potential 

      Paterson, Rachel Anne; Knudsen, Rune; Blasco-Costa, Isabel; Dunn, Alison M; Hytterød, Sigurd; Hansen, Haakon (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-18)
      Parasite distribution patterns in lotic catchments are driven by the combined influences of unidirectional water flow and the mobility of the most mobile host. However, the importance of such drivers in catchments dominated by lentic habitats are poorly understood. We examined parasite populations of Arctic charr Salvelinus alpinus from a series of linear-connected lakes in northern Norway to ...

    • Exploring trophic niches and parasite communities of sympatric Arctic charr and brown trout populations of southern Norway 

      Paterson, Rachel Anne; Nefjodova, Jelena; Salis, Romana; Knudsen, Rune (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-09)
      Catchment-scale variation between lake habitats has the potential to simultaneously influence the trophic niche and parasite community of fish hosts. In this study, we investigated the trophic niche and parasite community of sympatric Arctic charr and brown trout populations from two inter-connected southern Norwegian lakes at different altitudes. Arctic charr and brown trout occupied profundal and ...
