The genomics of adaptation de temperature tolerance in the threespine stickleback fish
In the face of global climate change, many species will have to adapt in order to persist in their natural environment. Characterizing the genes responsible of adaptation is highly important for understanding this evolutionary process. I am studying adaptation to temperature regime in a model system for ecology and evolution, the threespine stickleback fish. This species occurs along large latitudinal gradient and therefore faces a great range of temperature, making it an excellent model to study such adaptation. I will sample fish along both west and east coasts of North America. I will perform within and between population crosses and use cutting-edge sequencing technology in order to highlight the portion of the genomes responsible for temperature adaptation.
