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 ... -
Histopathological characterisation of retinal lesions associated to Diplostomum species (Platyhelminthes: Trematoda) infection in polymorphic Arctic charr Salvelinus alpinus
Padros, Francesc; Knudsen, Rune; Blasco-Costa, Isabel (Journal article; Tidsskriftartikkel; Peer reviewed, 2018)The eye represents an immune privileged organ where parasites can escape host reactions. This study provides the first systematic evidence of the pathology associated with <i>Diplostomum</i> sp. infection in the eye retina of fish (i.e. Arctic charr). Histological sections showed that the trematodes caused mechanical disengagement between the retinal pigmentary epithelium and the neurosensory retina, ...
