Journal ArticleDOI
Niche segregation of coexisting Arctic charr (Salvelinus alpinus) and brown trout (Salmo trutta) constrains food web coupling in subarctic lakes
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.
Journal ArticleDOI
Lake size and fish diversity determine resource use and trophic position of a top predator in high-latitude 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.
Journal ArticleDOI
Seasonal and ontogenetic shifts in the diet of Arctic charr Salvelinus alpinus in a subarctic lake
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.
Journal ArticleDOI
From clear lakes to murky waters : tracing the functional response of high-latitude lake communities to concurrent ‘greening’ and ‘browning’
Brian Hayden,Brian Hayden,Chris Harrod,Stephen M. Thomas,Antti P. Eloranta,Jukka-Pekka Myllykangas,Anna Siwertsson,Kim Præbel,Rune Knudsen,Per-Arne Amundsen,Kimmo K. Kahilainen +10 more
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.
Journal ArticleDOI
Lipid‐rich zooplankton subsidise the winter diet of benthivorous Arctic charr (Salvelinus alpinus) in a subarctic lake
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.
