Although dispersal is recognized as a key issue in several fields of population biology (such
as behavioral ecology, population genetics, metapopulation dynamics or evolutionary
modeling), these disciplines focus on different aspects of the concept and often make
different implicit assumptions regarding migration models. Using simulations, we investigate
how such assumptions translate into effective gene flow and fixation probability of selected
alleles. Assumptions regarding migration type (eg source-sink, resident pre-emption, or …
