On 10 Jan 2019, Joost Raeymaekers from Nord University, Bodø, Norway, will visit us and give a talk at the GELIFES seminar on Local adaptation in a common landscape – A tale of two stickleback species. Joost is an expert on the genomic architecture of sticklebacks. He has been involved in studying how various factors, including ecological heterogeneity, genomic architecture, population connectivity and life history, influence adaptive potential in key model organisms such as three-spined sticklebacks. His research is of particular relevance for the project of Apu.
