Journal ArticleDOI
Parallel phenotypic evolution of skull-bone structures and head measurements of Arctic charr morphs in two subarctic lakes
TL;DR: There is strong evidence for parallel evolution with some local adaptations in skull-bones and head morphology of the PB-morph and the LO-morph from separate lakes, suggesting adaptations to the deep-water environment but also to their separated dietary niches.
Journal ArticleDOI
Marine trophic niche‐use and life history diversity among Arctic charr Salvelinus alpinus in southwestern Greenland
Jan Grimsrud Davidsen,Michael Power,Rune Knudsen,Aslak Darre Sjursen,Gaute Kjærstad,Lars Rønning,Jo Vegar Arnekleiv +6 more
TL;DR: This study represents the first ecological baseline for partially anadromous populations of Greenland Arctic charr and shows that life-history strategy patterns and marine trophic niche use were consistent across the watercourses along several hundred kilometre coastline.
Journal ArticleDOI
Seasonal dietary shifts enhance parasite transmission to lake salmonids during ice cover
TL;DR: The winter period proved to be an important transmission window for parasites, with increased prevalence and intensity of amphipod‐transmitted parasites in Arctic charr and parasites transmitted through fish prey in brown trout.
Journal ArticleDOI
The effect of inter- and intraspecific competition on individual and population niche widths: a four-decade study on two interacting salmonids
Sebastian Prati,Eirik Haugstvedt Henriksen,Aslak Smalås,Rune Knudsen,Anders Klemetsen,Javier Sánchez-Hernández,Per-Arne Amundsen +6 more
Journal ArticleDOI
Introduction of Mysis relicta (Mysida) reduces niche segregation between deep-water Arctic charr morphs.
Rune Knudsen,Antti P. Eloranta,Anna Siwertsson,Rachel A. Paterson,Michael Power,Odd Terje Sandlund +5 more
TL;DR: The high importance of Mysis in Arctic charr diets may have reduced the ancestral niche segregation between the deep-water morphs and thereby increased their resource competition and potential risk of hybridization.
