TL;DR: This study demonstrates that both interspecific niche segregation between and individual trophic specialisation within generalist fish species can constrain food-web coupling and alter energy mobilisation to top consumers in subarctic lakes.

TL;DR: This study highlights that, because they determine the main energy source (littoral vs. pelagic) and the trophic position of generalist top predators, ecosystem size and fish diversity are particularly important factors influencing function and structure of food webs in high-latitude lakes.

TL;DR: It is suggested that a strong littoral reliance of fishes can be a feature in subarctic lakes throughout the year and liver could be more commonly used in stable-isotope studies of fish trophic niche shifts instead of using only the less responsive muscle tissue.

TL;DR: Changes along a gradient characteristic of the predicted future environment throughout the subarctic indicate that climate and land use driven eutrophication and browning are radically altering the function and fuelling of aquatic food webs in this biome.

TL;DR: It is demonstrated that lipid-rich zooplankton can subsidise the predominantly benthivorous diet of top consumers (here Arctic charr) in subarctic lakes and that littoral and pelagic trophic pathways can be highly integrated in high-latitude lakes.
