TL;DR: It is demonstrated that community structure may modulate the ontogenetic diet trajectories of and individual niche specialization within a top predator.

TL;DR: Seasonal dietary shifts appeared to have an effect on total mercury content in charr, and thus sampling month should be considered when designing future monitoring programmes.

TL;DR: This study demonstrates that local environmental characteristics and the biotic community strongly modify the hydropower-induced WLR impacts on reservoir fishes and ecosystems, and that there are no one-size-fits-all solutions to mitigate environmental impacts.

TL;DR: This study demonstrates how the succession of macrophyte vegetation, via its effects on the physical and biological complexity of the littoral zone and on the availability of small prey fish and zooplankton, can strongly influence individual niche variation among generalist fishes with different ontogenetic trajectories, and hence the overall food-web structures in lake ecosystems.

TL;DR: It is predicted that the small profundal charr morph in Skogsfjordvatn would have a similar trophic niche to the PB-morph in Fjellfrøsvatn and tested this by using stomach content and stable isotope analyses, and the prediction was supported.
