Demography, global change and senescence in two extremely long-lived species

This thesis investigates the effects of age-related in particular associated with senescence in two extremely long-lived species: the black-browed albatross (Thalassarche melanophrys) and the wandering albatrosses (Diomedea exulans). Initially we seek to determine the variations of different life-hi...
