Influence of developmental conditions on birds’ phenotype, from hatching to adult stage
Post-natal development is a crucial step for the rest of life. Indeed, individual physiological and behavioral functions are set-up and matured during that life-stage and final morphology is acquired at that time. Any stress or constraint perceived by the offspring during this period can have signif...

Post-natal development is a crucial step for the rest of life. Indeed, individual physiological and behavioral functions are set-up and matured during that life-stage and final morphology is acquired at that time. Any stress or constraint perceived by the offspring during this period can have significant morphological, physiological and/or behavioral consequences in the short but also in the long term. In fine, an individual’s fitness can be affected by the quality of its developmental conditions. This PhD aims to improve our understanding of the impact of abiotic developmental conditions (climate, human disturbance and exposure to a pesticide) and parental care on the quality of the produced chicks. Firstly, through the study of markers of stress and allostasis (stress response and telomere length) in Black-browed albatross and Snow petrel’s chicks, we demonstrated that in the short term, the quality of parental care - approximated by the age of the breeding individuals - was a major factor determining a chick’s phenotype.
