| Summary: | Understanding the ecological relationships between a species and the environment it inhabits is critical to determining species resilience to environmental change and future population viability. By assessing ecological relationships across multiple species greater insights into species intrinsic adaptations and external environmental factors can be revealed, contributing to a broader understanding of community ecology. This thesis examines the foraging behaviours and environmental drivers of demographic variability of four albatross species from subantarctic Macquarie Island (black-browed Thalassarche melanophris, grey-headed T. chrystostoma, light-mantled Phoebetria palpebrata and wandering albatrosses Diomedea exulans) to understand the ecological, morphological and life history relationships that influence species resilience to ecological shifts. Three of the four albatross species that inhabit Macquarie Island exist in small populations of less than 80 breeding pairs (for light-mantled albatross the ... |
