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...

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).

A multi-trait and multi-state approach allows us to model changes in traits with age, taking into account the effects of sex or reproductive status of the previous year in capture-recapture models.
