Resource Partitioning in Food, Space and Time between Arctic Charr (Salvelinus alpinus), Brown Trout (Salmo trutta) and European Whitefish (Coregonus lavaretus) at the Southern Edge of Their Continuous Coexistence.
Autor: Hallvard Jensen, Mikko Kiljunen, Rune Knudsen, Per-Arne Amundsen
Publikováno v: PLoS ONE, Vol 12, Iss 1, p e0170582 (2017)
Arctic charr and European whitefish are considered to be strong competitors in lakes, with the latter usually being the superior species. However, high niche plasticity and lake morphometry may suggestively facilitate resource partitioning and coexis

Publikováno v: Fisheries Management and Ecology. 22:295-306
Knowledge of predator–prey dynamics is essential to understand ecosystem functioning. Quantification of such interactions is important for fisheries management, in particular in the case of stocking programmes. Here, food consumption rates (FCR) we

Dietary ontogeny and niche shift to piscivory in lacustrine brown trout Salmo trutta revealed by stomach content and stable isotope analyses
Autor: Hallvard Jensen, Per-Arne Amundsen, Mikko Kiljunen
Publikováno v: Journal of Fish Biology. 80:2448-2462
The feeding ecology and ontogeny of a large size range of brown trout Salmo trutta in Lake Fyresvatnet, southern Norway, were examined by stomach content and stable isotope analyses. According to the stomach contents, the S. trutta changed their diet

Predation by brown trout (Salmo trutta) along a diversifying prey community gradient
Autor: Hallvard Jensen, Per-Arne Amundsen, Tommi Malinen, Antti Tuomaala, Thomas Bøhn, Karl Øystein Gjelland, Kimmo K. Kahilainen
Predation has a fundamental role in aquatic ecosystems, but the relative importance of factors governing prey selection by predators remains controversial. In this study, we contrast five lakes of a subarctic watershed to explore how prey community c
