TI  - The adaptive capacities of seabirds to face environmental variability: the role of heterogeneity within populations
N2  - Population dynamics is driven by several life history traits shaped by the evolutionary history of the population. The alteration of one of these traits by environmental constraints may thus have effects on the population persistence. Individual adjustments of some phenotypic traits could then enable this population to rapidly respond to these constraints without the immediate necessity of genetic adaptations. During this PhD project, we identified variability in some of these traits in 3 sentinel species of polar ecosystems. These results allowed us to better understand the associations between these traits and the evolutionary pressures underlying these associations, as well as the importance of traits such as personality in the amount of variability in individuals’ fitness that remains unexplained. In the long term, we should then be able to better gauge the adaptive capacity of populations to face global changes.
