| Summary: | Climate induced variability of prey abundance and its' distribution, is a dominant factor regulating marine predator lifetime reproductive success and population viability. Seabirds are long-lived and they have evolved life-history traits such as delayed sexual maturity and intermittent breeding that buffer them against environmental variability. However, some species that have restricted dietary and range niches may be more sensitive to persistent negative climate perturbations. Therefore, gaining an understanding of how climate variability affects foraging ecology and reproductive parameters will be imperative if we are to determine the viability of seabird populations into the future. Doing so is important given the predictions that the Earth's climate will continue to change at an accelerated rate in the coming century. This thesis investigated whether the short-tailed shearwater (Ardenna tenuirostris), an abundant seabird of the Southern Ocean, will be resilient in a rapidly changing environment. The ... |
