Harp seals are the most abundant marine mammal in the north Atlantic. As an ice obligatory
predator, they reflect changes in their environment, particularly during a period of climatic …

Arctic sea ice loss has direct consequences for predators. Climate‐driven distribution shifts
of native and invasive prey species may exacerbate these consequences. We assessed …

In marine ecology, dietary interpretations of faunal assemblages often rely on nitrogen
isotopes as the main or only applicable trophic level tracer. We investigate the geographic …

The climate change-induced northward movement of sub-Arctic marine mammals increases
their range overlap and interactions with native Arctic species. We compared feeding …

Introduction Competition embodies species struggle for space and food and is, therefore, a
critical evolutionary mechanism influencing species spatiotemporal patterns and …

Through collaboration with Inuit hunters, we examined the stomach contents of 142 seals
(ringed seals [Phoca hispida; n= 135], bearded seals [Erignathus barbatus; n= 6], and one …

Arctic food webs are being impacted by borealisation and environmental change. To
quantify the impact of these multiple forcings, it is crucial to accurately determine the …

Conceptually, trophic niche overlap and species abundance can describe the strength and
number of interspecific trophic interactions to determine the competitive impact on …

Trophic niche and diet comparisons among closely sympatric marine species are important
to understand complex food webs, particularly in regions most affected by climate change …

Climate-induced alterations to Arctic sea ice dynamics are influencing resource availability
and distribution, and in turn, restructuring Arctic marine food webs, which can be monitored …
