TL;DR: Various aspects of phenotypic and life-history variation of Atlantic salmon Salmo salar L., brown trout Salmo trutta L., and Arctic charr Salvelinus alpinus are reviewed.

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.

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.

TL;DR: The exceptional diversity of arctic charr provides a unique potential for further progress in studies on ecologically driven evolution within the frames of modern theory of developmental plasticity, adaptive radiation and adaptive speciation.

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.
