ArticleEffects of Maternal Traits and Individual Behavior on the Foraging Strategies and Provisioning Rates of an Income Breeder, the Antarctic Fur SealCrocker, Daniel E.The ability of an animal to acquire energy will affect its allocation to offspring and will ultimately influence fitness. This study investigated the relative influence of maternal traits, seasonal demands of pup-rearing, and individual effects on the . . .
ArticleDynamic Influence of Maternal and Pup Traits on Maternal Care during Lactation in an Income Breeder, the Antarctic Fur SealCrocker, Daniel E.Life-history theory predicts that selection will favor optimal levels of parental effort that balance benefits of current reproduction with costs to survival and future reproduction. The optimal level of effort depends on parental traits, offspring tr . . .
ArticleBiological and Environmental Drivers of Energy Allocation in a Dependent Mammal, the Antarctic Fur Seal PupCrocker, Daniel E.Little is known about how variation in the pattern and magnitude of parental effort influences allocation decisions in offspring. We determined the energy budget of Antarctic fur seal pups and examined the relative importance of timing of provisioning . . .
