- Authors
Holst, Meike; Stirling, Ian; Hobson, Keith A.
- Abstract
Examines the diets of ringed seals (Phoca hispida) on the west (Grise Fiord, Nunavut) and east (Qaanaaq, Greenland) sides of the polynya, using conventional stomach content analysis, as well as inferences from stable isotope ratios in seal muscle. Collection of stomach and muscle tissue samples; Dominant prey types in diets of immature ringed seals and adults; Findings; Suggestion that differences in diets of ringed seals from the east and west sides of the North Water Polynya may be due to differences in prey distribution and/or differences in biological productivity and fish biomass within the polynya.
