Effect of a low-fat diet on body composition and blubber fatty acids of captive juvenile harp seals (Phoca groenlandica)
Kirsch, PE; Iverson, Sara J.; Bowen, WD (2000-01)We investigated the effects of a change from a high-fat diet to a low-fat diet of differing fatty acid (FA) composition on the body composition and blubber FA of five captive juvenile harp seals. Seals that had been ... -
The energetics of male reproduction in an acquatically mating pinniped, the harbour seal
Coltman, DW; Bowen, WD; Iverson, Sara J.; Boness, DJ (1998-07)The energy expenditure of breeding male harbour seals, Phoca vitulina, on Sable Island, Nova Scotia, was investigated by measuring changes in body mass, body composition, and water flux using isotope dilution. Seals lost ... -
Estimation of total body water in pinnipeds using hydrogen-isotope dilution
Bowen, WD; Iverson, Sara J. (1998-05)No abstract available. -
Variation in milk production and lactation performance in grey seals and consequences for pup growth and weaning characteristics
Mellish, JAE; Iverson, Sara J.; Bowen, WD (1999-12)Phocid seals are one of the few groups of mammals capable of sustaining the energetic demands of lactation entirely through body nutrient stores while fasting. Lactation performance of the female in turn influences the ... -
Weaning mass affects changes in body composition and food intake in harbour seal pups during the first month of independence
Muelbert, MMC; Bowen, WD; Iverson, Sara J. (2003-05)In phocid seals, the transition to nutritional independence is abrupt, with females abandoning their offspring after weaning and returning to sea. We hypothesized that body size at weaning may play an important role in ...
