Impact of Tusk Anomalies on the Long-Term Foraging Ecology of Narwhals. [PDF]
Ecol EvolWe combined stable δ13C and δ15N isotope analysis and genetic sexing to investigate whether narwhals with dental anomalies have a distinct long‐term foraging ecology. Our results showed no difference in stable isotope signature of two‐tusked male and one‐tusked female narwhals relative to normal‐tusked narwhals, indicating that an extra tusk does not ...

Summer foraging behaviour of shallow-diving seabirds and distribution of their prey, Arctic cod (Boreogadus saida), in the Canadian Arctic [PDF]
Polar Research, 2012 Productive areas in the Canadian Arctic seasonally provide top predators with accessible and often predictable sources of energy. Arctic cod (Boreogadus saida) aggregate in shallow bays during the summer and are exploited by seabirds and marine mammals ...

Gastrointestinal evacuation of particulate matter in polar cod Boreogadus saida [PDF]
Marine Ecology Progress Series, 1999 Gastrointestinal evacuation of inert particles was monitored in the polar cod Boreogadus saida (Lepechin), held at a temperature of 0.5°C. Fish (31.8 g ± 0.8 SD) were fed a moist diet, based on natural prey items, containing a particulate marker. Evacuation of marker from the gastrointestinal tract started 48 h after ingestion of a meal.

Modeling Ringed and Bearded Seal Future Habitats Indicates Stability, Shifts, and Refugia. [PDF]
Glob Chang BiolEvery year, ringed seals and bearded seals rely on specific ice and snow conditions to support events such as feeding or reproduction. With Earth System Models, we simulate habitat over 1850–2100, revealing a relatively stable past habitat contrasting with rapid regional shifts in contemporary simulations and future projections.

Combined effects of crude oil exposure and warming on eggs and larvae of an arctic forage fish
Scientific Reports, 2021 Climate change, along with environmental pollution, can act synergistically on an organism to amplify adverse effects of exposure. The Arctic is undergoing profound climatic change and an increase in human activity, resulting in a heightened risk of ...

Can vertical separation of species in trawls be utilized to reduce bycatch in shrimp fisheries?
PLoS ONE, 2021 Several shrimp trawl fisheries use a Nordmöre sorting grid to avoid bycatch of fish. However, small fish can pass through the grid. Therefore, the retention of juvenile fish often remains an issue during shrimp trawling.
