DOI: 10.1007/s00244-020-00749-4
Abstract: Blubber taken from ringed seals (Pusa hispida) during a subsistence hunt at Ulukhaktok, NT (formerly Holman, NWT) at intervals between 2002 and 2015 was analysed for polybrominated diphenyl ether (PBDE) congeners. Results from these analyses… read more here.

DOI: 10.1093/conphys/coaa115
Abstract: We investigate the relationship among reproduction, stress and diet in bearded and ringed seals by measuring hormones and stable isotopes stored in claws. As a result, we calculated pregnancy rate of individual females and found… read more here.

DOI: 10.33265/polar.v38.3483
Abstract: Ringed seals are a central component of the Arctic ecosystem; they have a circumpolar distribution and are both important predators of lower trophic animals (invertebrates and fishes) and prey for polar bears and coastal human… read more here.

DOI: 10.3354/esr01087
Abstract: Although Arctic ringed seals Phoca hispida hispida are currently abundant and broadly distributed, their numbers are projected to decline substantially by the year 2100 due to climate warming. While understanding population structure could provide insight… read more here.

A Multi-Matrix Metabolomic Approach in Ringed Seals and Beluga Whales to Evaluate Contaminant and Climate-Related Stressors
Sign Up to like & getrecommendations! Published in 2022 at "Metabolites"
DOI: 10.3390/metabo12090813
Abstract: 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 ethers (PBDEs) and mercury (Hg).… read more here.
