A Multi-Matrix Metabolomic Approach in Ringed Seals and Beluga Whales to Evaluate Contaminant and Climate-Related Stressors

Metabolites, 2022
As a high trophic-level species, ringed seals (Pusa hispida) and beluga whales (Delphinapterus leucas) are particularly vulnerable to elevated concentrations of biomagnifying contaminants, such as polychlorinated biphenyls (PCBs), polybrominated diphenyl

Underwater noise impact of a ferry route on dive patterns of transiting Baltic ringed seals [PDF]

Estonian Journal of Earth Sciences, 2022
To understand the impact of underwater anthropogenic noise on marine life, it is crucial to collect more data about the onset of behavioural reactions of marine species. Three free-ranging ringed seals (Phoca hispida botnica) were marked with GPS tags to

Age and sex composition of seals killed by polar bears in the eastern Beaufort Sea. [PDF]

PLoS ONE, 2012
Polar bears (Ursus maritimus) of the Beaufort Sea enter hyperphagia in spring and gain fat reserves to survive periods of low prey availability. We collected information on seals killed by polar bears (n=650) and hunting attempts on ringed seal (Pusa ...

Spatial variation in carbon source use and trophic position of ringed seals across a latitudinal gradient of sea ice

Ecological Indicators, 2022
Anthropogenic climate change is causing changes to the Arctic sea-ice system with implications for the magnitude and timing of Arctic pelagic and ice-associated (sympagic) primary production that influences food web interactions.

Multi-dietary tracer approach reveals little overlap in foraging ecology between seasonally sympatric ringed and harp seals in the high Arctic

Frontiers in Marine Science, 2022
The rapid rate of climate change in the Arctic is causing broad-scale changes to the physical environment and biological communities. Characterizing the foraging ecology and habitat use of Arctic marine top predators of high ecological and cultural ...

Seasonal changes in diel haul‐out patterns of a lacustrine ringed seal (Pusa hispida saimensis)

Ecology and Evolution, 2023
Seasonal changes in diel haul‐out patterns of the lacustrine Saimaa ringed seal (Pusa hispida saimensis) were studied using a combination of satellite telemetry and camera traps during 2007–2015. We found the haul‐out activity patterns to vary seasonally.

Vestnik MGTU, 2017
The results of studying the influence of optical characteristics of sea water on the ability of earless seals to differentiate tablets of blue and red colours have been presented.

Exploitation of ringed seals (Phoca hispida) in Greenland

NAMMCO Scientific Publications, 1998
The ringed seal (Phoca hispida) is the most important game for the Inuit hunters of Greenland, providing many of the basic needs in the original culture.

Combined genetic and telemetry data reveal high rates of gene flow, migration, and long-distance dispersal potential in Arctic ringed seals (Pusa hispida). [PDF]

PLoS ONE, 2013
Ringed seals (Pusa hispida) are broadly distributed in seasonally ice covered seas, and their survival and reproductive success is intricately linked to sea ice and snow.

Novel terrestrial haul-out behaviour by ringed seals (Pusa hispida) in Svalbard, in association with harbour seals (Phoca vitulina)

Polar Research, 2017
Ringed seals (Pusa hispida) are the most ice-associated of all Arctic pinnipeds. In the Svalbard area, this species has always given birth, moulted and rested on sea ice. In addition, much of their food has been comprised of ice-associated prey. Recently,
