Spatial and temporal variation can confound interpretations of relationships within and
between species in terms of diet composition, niche size, and trophic position (TP). The …

Environmental change in the Arctic has impacted the composition and structure of marine
food webs. Tracking feeding ecology changes of culturally-valued Arctic char (Salvelinus …

Individual specialization (IS), where individuals within populations irrespective of age, sex,
and body size are either specialized or generalized in terms of resource use, has …

Environmental variation influences resource distribution, thereby affecting animal movement
and foraging decisions. Climate change is altering environmental processes worldwide, but …

Arctic ecosystem dynamics are shifting in response to warming temperatures and sea ice
loss. Such ecosystems may be monitored by examining the diet of upper trophic level …

Stomach content and stable isotope analysis (δ13C and δ15N from liver and muscle) were
used to identify habitat and seasonal prey selection by ringed seals (Pusa hispida; n= 21) …

Climate change is leading to northward shifts in species distributions that is altering
interspecific interactions at low-and mid-trophic levels. However, little attention has been …

The cumulative effect of individual‐level foraging patterns may have important
consequences for ecosystem functioning, population dynamics and conservation. Dietary …

Crabeater seals exhibit extreme dietary specialization, feeding almost exclusively on
Antarctic krill. This specialization has inextricably linked habitat use, life history and …
