Geographic parthenogenesis is a term applied to describe a large variety of patterns where sexual and related asexual differ in their geographic distribution. More specifically, asexuals are stated to occur in so-called marginal habitats, generally linked to the edge of a species distribution. Although many researches have been carried out to understand the benefits of sexual compared to asexual reproduction, mathematical models that consider geographic parthenogenesis as their focal question are few. During my presentation I will briefly present the individual-based model Ive developed and show how the effect of sex on the mean phenotype and genetic variance affect the establishment of the motif.
