Abstract Information about the dietary composition of a species is crucial to understanding
their position and role in the food web. Increasingly, molecular approaches such as DNA …

The knowledge on benthic trophic relations is particularly important for understanding the
functioning of still pristine and less studied Arctic Ocean ecosystems. This study examines …

Fatty acid (FA) compositions provide insights about storage and feeding modes of marine
organisms, characterizing trophic relationships in the marine food web. Such compositional …

Species with a broad and flexible diet may be at an advantage in a rapidly changing
environment such as in today's Arctic ecosystems. Polar cod (Boreogadus saida), an …

The introduction of a large predatory snow crab, Chionoecetes opilio, into the Kara Sea is a
unique situation where the impact of an invasive species affecting an otherwise undisturbed …

The Arctic marine ecosystem is changing fast due to climate change, emphasizing the need
for solid ecological baselines and monitoring. The polar cod Boreogadus saida functions as …

Increasing terrestrial run-off from melting glaciers and thawing permafrost to Arctic coastal
areas is expected to facilitate re-mobilization of stored legacy persistent organic pollutants …

Arctic and sub-Arctic marine ecosystems are experiencing some of the highest sea surface
warming in the world, which has intensified water column stratification and subsequently …

Fatty acid (FA) analysis of consumer tissues has recently shown utility in drawing further
inferences about trophic niche dynamics of marine predators such as sharks. In this study …

Scientists generally believe that the products of photosynthesis raining down from above
support the community of organisms living on the ocean bottom deeper than light can reach …
