Migration and climate change

Because of its scale and its great representation within the animal kingdom, migration is one of the most spectacular forms of adaptation to environmental variations. However, the ability of different bird species to adjust their migration to human-induced environmental changes, such as climate change, remains relatively unknown. Yet this represents a major challenge for biodiversity conservation and management, based on the scientific challenge of understanding the ecosystem causes and consequences of the migration process. Research topics and projects Through the study of several populations of migratory and sedentary birds, my research project aims to understand how individuals adapt their migratory strategies in a context of climate change and anthropogenic pressures, and to assess the consequences of these choices on individual selective value (reproductive success and survival being easily estimated in these philopatric species).
