Analysis of the condition of female (body fat and protein composition, weight and diet) Weddell seals (Leptonychotes weddellii) and the implication for reproductive success
Entry ID: K063_2002_2004_NZ_1

Abstract: Weddell seals lay down substantial fat deposits during the non-breeding season and then expend the stored energy during an intensive lactation period. Fluctuations in energy acquisition prior to breeding are expressed as variations in maternal mass and condition at parturition. Failure to locate sufficient food prior to parturition will result in poor reproductive success. The link between ... View entire text
