Brief description Effects of maternal foraging success and oceanographic variation on offspring behaviour and survival in the southern elephant seal. Juvenile survival is the key determinant of mammalian population performance, but the proximate determinants of this have rarely been established in large, long-lived predators. Southern elephant seals, with their concentrated lactation effort and marked separation of energy acquisition (at-sea foraging) and expenditure (on-land lactation) provide an ideal model for investigating these factors. In this study, we investigate the partitioning of pre-partum performance (fat acquired in mothers) relative to spatial-temporal variation in ocean productivity and the effect of this expenditure on offspring condition and survival. Here, the final missing link of energy transfer and its effects on offspring will be a major outcome of this project.
