• Mining various genomic resources to resolve old alpha-taxonomy questions: A test of the species hypothesis of the Proteocephalus longicollis species complex (Cestoda: Platyhelminthes) from salmonid fishes 

      Brabec, Jan; Rochat, Eloïse Coralie; Knudsen, Rune; Scholz, Tomas; Costa, Isabel Blasco (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-24)
      High-throughput sequencing strategies became commonly employed to study non-model parasites, but the corresponding genomes and transcriptomes were seldom mined following the original publication. Similar to the data generated with genome skimming techniques based on shallow-depth shotgun gen omes, various genomic and transcriptomic resources can be screened for useful molecular phylogenetic markers ...
    • Salmon-lice as a potential threat to anadromous Arctic charr populations 

      Rochat, Eloïse Coralie; Grenier, Gabrielle; Muladal, Rune; Jensen, Hallvard; Knudsen, Rune (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-25)
      Salmon-lice have the potential to change the behaviour and growth of their salmonid host species. Here, the baseline infection levels of salmon-lice of post-smolts (n = 815) and veteran migrants (n = 875) of sea-run Arctic charr (Salvelinus alpinus Linnaeus, 1758) were monitored over two successive years in a sub-Arctic Norwegian fjord without farming of salmonids. All Arctic charr were collected ...
    • Temporal stability of polymorphic Arctic charr parasite communities reflects sustained divergent trophic niches 

      Rochat, Eloïse Coralie; Paterson, Rachel; Costa, Isabel Blasco; Power, Michael; Adams, Colin E.; Greer, Ron; Knudsen, Rune (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-05)
      Polymorphic Arctic charr Salvelinus alpinus populations frequently display distinct differences in habitat use, diet, and parasite communities. Changes to the relative species densities and composition of the wider fish community have the potential to alter the habitat niche of sympatric Arctic charr populations. This study evaluated the temporal stability of the parasite community, diet, and stable ...
