Seal and Polar Bear Behavioral Response to an Icebreaker Vessel in Northwest Greenland

Human-Wildlife Interactions, 2019
Icebreaker vessels are important scientific tools, enabling access and research within the polar regions of the world, including the High Arctic. These vessels have the potential to overlap with marine mammal habitats in infrequently studied areas ...

Are liver and renal lesions in East Greenland polar bears (Ursus maritimus) associated with high mercury levels?

Environmental Health, 2007
Background In the Arctic, polar bears (Ursus maritimus) bio-accumulate mercury as they prey on polluted ringed seals (Phoca hispida) and bearded seals (Erignathus barbatus).

A Bayesian approach to include Indigenous Knowledge and satellite telemetry data in habitat selection functions

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
Our work points to the importance of both Western science and IK data sources in models used for conservation and management decisions. We show how the models that include the IK result in more informed predictions and the value of IK when predicting important areas for species that may be relied upon for conservation and management decisions.

Abundance and distribution of ringed and bearded seals in the Chukchi Sea: a reference for future trends

Arctic Science
Ringed (Pusa hispida) and bearded (Erignathus barbatus) seals are vulnerable to decreasing sea ice habitat in the rapidly warming Arctic. In April and May 2016, we conducted an aerial survey over the ice-covered areas of the Chukchi Sea using thermal and

Sharing Is Caring?—Pathogens and Pathogen‐Specific Antibodies in Arctic Endemic Seal Species and the Newly Sympatric Harbor Seals in Kongsfjorden, Svalbard

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Climate change associated transformations of Arctic marine ecosystems are having detrimental impacts on Arctic endemic marine mammals. However, warming conditions are providing new habitats for temperate marine mammals, some of which are expanding into Arctic regions, posing a threat of novel pathogen introduction and disease transmission.

Seasonal and diurnal marine mammal presence in the proposed marine protected area of Southampton Island, Hudson Bay, Nunavut as revealed by passive acoustic monitoring

Arctic Science
Marine protected areas contribute to mitigating the effects of human activities on marine ecosystems. The waters of Southampton Island, Nunavut, Canada are under consideration to become a marine protected area, but baseline information of marine mammal ...

Climate‐linked evolution and genetics in a warming Arctic

Ecological Monographs, Volume 96, Issue 1, February 2026.
Abstract Knowledge of evolutionary patterns and genetic variation across a species' range is important for determining conservation and management strategies. The Arctic is the fastest‐warming ecosystem on Earth and has already reached temperature increases not expected in the rest of the world until the end of the century.

Pitch separation as a possible jamming-avoidance mechanism in underwater calls of bearded seals (Erignathus barbatus)

, 1999
Bearded seals (Erignathus barbatus) produce simultaneous loud, long, narrowband underwater trills. It is likely that calls separated by 1/3 octave will not mask each other. Three call (trill) types were identified.
