Mutation, selection and recombination have been at the heart of population geneticists since its early beginnings. Yet, joint modeling of these processes has remained a major challenge, especially in structured populations. Recently, the perspective of genome-wide sets of markers and DNA sequence data on a population-genetic scale has spurred the interest in extracting information about population history from observable variation at multiple loci. This goal will not be reached before we have a thorough theoretical understanding of the evolutionary processes in models with multiple loci. As most populations are structured – either geographically or due to different sexes or genetic backgrounds – biologically relevant approaches account for such structure. This mini-symposium collects theoretical contributions, including analytical, numerical, and simulation-based work, to understand the interaction of evolutionary forces in structured populations.
