On the dynamics and selective transport of fatty acids and organochlorines in lactating grey seals (Halichoerus grypus) [PDF]
, 2010 This thesis examines fatty acid (FA) and polychlorinated biphenyl (PCB) dynamics in a marine top predator, the grey seal (Halichoerus grypus,) and their transfer during lactation from mother to offspring.

Health, disease, mortality and survival in wild and rehabilitated harbor seals (Phoca vitulina) in San Francisco Bay and along the central California coast [PDF]
, 2011 Conventional methods for health assessment of wild-caught and stranded seals were used to describe the disease status of harbor seals in California. Clinical chemistry, infectious disease prevalence, immune function, and contaminant data were collected ...

Polar Research, 2019 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 populations. They depend on

Distribution, abundance and biology of ringed seals (Phoca hispida): an overview
NAMMCO Scientific Publications, 1998 The ringed seal (Phoca hispida) has a circumpolar Arctic distribution. Because of its great importance to northern communities and its role as the primary food of polar bears (Ursus maritimus) the ringed seal has been studied extensively in Canada ...

Foraging ecology of ringed seals (Pusa hispida), beluga whales (Delphinapterus leucas) and narwhals (Monodon monoceros) in the Canadian High Arctic determined by stomach content and stable isotope analysis [PDF]
Polar Research, 2015 Stomach content and stable isotope analysis (δ13C and δ15N from liver and muscle) were used to identify habitat and seasonal prey selection by ringed seals (Pusa hispida; n=21), beluga whales (Delphinapterus leucas; n=13) and narwhals (Monodon monoceros;

, 2003 Polar bears Ursus maritimus are predators of phocid seals, but they also forage opportunistically on a variety of other species. In the Barents Sea—Svalbard area, their diet is thought to consist almost exclusively of ringed seals Phoca hispida, bearded ...
