    • Divergent functional traits in three sympatric Arctic charr Salvelinus alpinus morphs are not coupled with the age of the lineage divergence 

      Bryce, Carolyn; Alicia, Fraser; Knudsen, Rune; Greer, Ron; Adams, Colin Ean (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-10-24)
      Three genetically discrete morphs of Arctic charr in Loch Rannoch, Scotland originated from a recent divergence within the lake (in situ) (piscivore and benthivore morphs) and from secondary contact of two older lineages (ex situ; a planktivore–piscivore/ benthivore divergence). To test if the expression of traits with strong functional roles was linked to the age of the divergence, fin and ...

    • 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 ...
