TL;DR: Investigation of trophic interactions in large subarctic Lake Inarijarvi in northern Finland indicates that introduced lake trout may to some extent compete with and prey upon native Arctic charr, but currently have only a minor if any impact on native fishes and food web structure.

TL;DR: It is demonstrated that a recently described profundal spawning piscivore PP-morph of Arctic charr in a subarctic lake has evolved typical piscvore traits, similar to the co-occurring brown trout but different from the sympatric littoral spawning omnivore LO- Morph of Arcticcharr.

TL;DR: Brown trout yield was generally lower in lakes where other fish species were present than in lakes with brown trout only, and showed an overall negative relationship with increasing temperature and a positive relationship with lake shoreline complexity.

TL;DR: In this paper, the authors compared the size, growth, condition, and niche use (i.e., habitat and diet) of allopatric Arctic charr (Salvelinus alpinus) populations in two neighboring and comparable Norwegian mountain lakes.

TL;DR: Gut content and stable isotope analyses revealed that small of both species were predominantly piscivorous, with asp consuming more cyprinid prey and pikeperch more percid prey, suggesting that trophic segregation can be dynamic and variable among systems.
