Title: The role of sex separation in neutral speciation
Author: Baptestini, EM

Abstract: Neutral speciation mechanisms based on isolation by distance and assortative mating, termed topopatric, has recently been shown to describe the observed patterns of abundance distributions and species-area relationships. Previous works have considered this type of process only in the context of hermaphroditic populations. In this work, we extend a hermaphroditic model of topopatric speciation to populations where individuals are explicitly separated into males and females. We show that for a particular carrying capacity, speciation occurs under similar conditions, but the number of species generated is lower than in the hermaphroditic case. As a consequence, the species-area curve has lower exponents, especially at intermediate scales. Evolution results in fewer species having more abundant populations.
