Project

Spatio-temporal patterns of selection in blue tits (C. caeruleus)
My project aims to contribute to a better understanding of constraints on adaptation. In response to an environmental change, populations can migrate to another place, be adapted through the mechanism of phenotypic plasticity, or evolve by natural selection (local adaptation). Our theoretical models fail to predict evolutionary change of populations. This suggests the presence of few constraints on adaptation. During my PHD project, I will try to estimate and quantify some of constraints on adaptation by working on long term dataset (37 years) of Mediterranean blue tits. In first time, (1) I will estimate spatio-temporal patterns of natural selection, (2) I will try to estimate any environmental covariance, and (3) I will investigate if the micro-evolutionary response can be limited by the genetic architecture.
