Models of adaptation to climate change with complex life histories
Climate warming has been the epitome of rapid global environmental changes induced by anthropogenic activities. The need to predict species responses to these challenges has been a strong motivation to develop the theory of adaptation to rapid and ongoing environmental changes. Early theory provided strong conceptual insights based on simple models, notably assuming non-overlapping generations. However, many organisms, some of major conservation or agronomic interest, have complex life histories structured in different ages and stages. I will present some of the work we have done to integrate life history in models of adaptation to changing environments. These models strongly emphasize the link between ecological and evolutionary dynamics. We demonstrate in particular how changing environments can trigger eco-evolutionary feedback loops with major consequences both on life history and on the fate of populations.
