  • Effect of a low-fat diet on body composition and blubber fatty acids of captive juvenile harp seals (Phoca groenlandica) 

    Kirsch, PE, SJ Iverson, and WD Bowen. 2000. "Effect of a low-fat diet on body composition and blubber fatty acids of captive juvenile harp seals (Phoca groenlandica)." Physiological and Biochemical Zoology 73(1): 45-59. Copyright © 2000 The University of Chicago Press.
    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, WD Bowen, SJ Iverson, and DJ Boness. 1998. "The energetics of male reproduction in an acquatically mating pinniped, the harbour seal." Physiological zoology 71(4): 387-399. Copyright © 2005 The University of Chicago Press.
    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, and SJ Iverson. 1998. "Estimation of total body water in pinnipeds using hydrogen-isotope dilution." Physiological zoology 71(3): 329-332. Copyright © 1998 The University of Chicago Press.

  • Variation in milk production and lactation performance in grey seals and consequences for pup growth and weaning characteristics 

    Mellish, JAE, SJ Iverson, and WD Bowen. 1999. "Variation in milk production and lactation performance in grey seals and consequences for pup growth and weaning characteristics." Physiological and Biochemical Zoology 72(6): 677-690. Copyright © 1999 The University of Chicago Press.
    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, WD Bowen, and SJ Iverson. 2003. "Weaning mass affects changes in body composition and food intake in harbour seal pups during the first month of independence." Physiological and Biochemical Zoology 76(3): 418-427. Copyright © 2003 The University of Chicago Press.
    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 ...
