Parallel evolution of ecomorphological traits in the European whitefish Coregonus lavaretus (L.) species complex during postglacial times
Kjartan Østbye,Per-Arne Amundsen,Louis Bernatchez,Anders Klemetsen,Rune Knudsen,Roar Kristoffersen,T. F. Næsje,Kjetil Hindar +7 more
TL;DR: In this paper, the authors studied nine Norwegian lakes in three watercourses, which each harboured pairs of divergent whitefish morphs and compared the morphology and life history of these morphs, documented the extent of genetic differentiation between them and contrasted the niche use of sympatric morphs along both the habitat and resource axes.
Journal ArticleDOI
Culling prey promotes predator recovery--alternative states in a whole-lake experiment.
Lennart Persson,Lennart Persson,Lennart Persson,Per-Arne Amundsen,Per-Arne Amundsen,Per-Arne Amundsen,André M. de Roos,André M. de Roos,André M. de Roos,Anders Klemetsen,Anders Klemetsen,Anders Klemetsen,Rune Knudsen,Rune Knudsen,Rune Knudsen,Raul Primicerio,Raul Primicerio,Raul Primicerio +17 more
TL;DR: It is shown, for predators feeding on prey that exhibit food-dependent growth, that culling of fish prey may promote predator recovery and represents an experimental demonstration of an alternative stable state in a large-scale field system.
Journal ArticleDOI
Food web topology and parasites in the pelagic zone of a subarctic lake
Per-Arne Amundsen,Kevin D. Lafferty,Rune Knudsen,Raul Primicerio,Anders Klemetsen,Armand M. Kuris +5 more
TL;DR: The study provides a highly resolved food web from the pelagic zone of a subarctic lake and demonstrates that their incorporation may substantially alter considerations of food-web structure and functioning and suggests that the linkage density of free-living species affects their exposure to trophically transmitted parasites.
Journal ArticleDOI
Incipient speciation through niche expansion: an example from the Arctic charr in a subarctic lake
TL;DR: The profundal morph of Fjellfrøsvatn therefore utilize a food resource niche that neither the littoral morph nor comparable monomorphic populations exploit, which suggests that intraspecific resource competition has driven incipient ecological speciation of the Profundal charr of FJellfr Norwegian.
Journal ArticleDOI
Intraspecific competition and density dependence of food consumption and growth in Arctic charr
TL;DR: It is demonstrated that quantitative food consumption represents the connective link between population density and individual growth rates, apparently being highly influenced by intraspecific competition for limited resources.
