The Greenland shark (Somniosus microcephalus), an iconic species of the Arctic Seas,
grows slowly and reaches> 500 centimeters (cm) in total length, suggesting a life span well …

Mercury (Hg) is a ubiquitous toxic metal that biomagnifies in food webs, and can reach high
concentrations in top predators. Evaluating Hg biomagnification in Arctic marine food webs …

Sharks are a diverse group of mobile predators that forage across varied spatial scales and
have the potential to influence food web dynamics. The ecological consequences of recent …

Freshwater runoff from the Greenland Ice Sheet (GIS) can be an important driver influencing
plankton community structure in Greenland fjords. In the present study, we describe …

Trace metals and metalloids in aquatic ecosystems may lead to adverse effects on the
survival of fish, especially in the sensitive life stages of vulnerable species. It is still unknown …

The Arctic is undergoing unprecedented environmental change. Rapid warming, decline in
sea ice extent, increase in riverine input, ocean acidification and changes in primary …

There is little doubt that Arctic ecosystems will continue to face unprecedented change in the
coming decades. The identification of food web structures that confer stability to these …

Greenland sharks are widely distributed and most likely a highly abundant predator in arctic
waters. Greenland sharks have previously been considered scavengers, but recent studies …

Studies that use biomarkers to elucidate consumer diets often must assume that these
signatures are relatively invariant in space and time. We tested this assumption for multiple …

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