Dimensionality of sexual isolation during reinforcement and ecological speciation in Timema cristinae stick insects
Background: Speciation can involve variation in the dimensionality of population divergence (defined as variation in the number of independent ecological variables, phenotypic traits, or genes differing between populations). Recent work indicates that reproductive isolation between populations is multidimensional, but that this multidimensionality has an upper limit. A remaining question is how...
متن کاملEcological explanations for (incomplete) speciation.
Divergent natural selection has been shown to promote speciation in many taxa. However, although divergent selection often initiates the process of speciation, it often fails to complete it. Several time-based, geographic and genetic factors have been recognized to explain this variability in how far speciation proceeds. We review here recent evidence indicating that variability in the complete...
متن کاملCan reinforcement complete speciation?
Hybridization is common in nature, even between "good" species. This observation poses the question of why reinforcement is not always successful in leading to the evolution of complete reproductive isolation. To study this question, we developed a new "quasi-linkage disequilibrium" (QLD) approximation to obtain the first analytic results for the evolution of modifiers that increase mate discri...
متن کاملCoupling, Reinforcement, and Speciation.
During the process of speciation, populations may diverge for traits and at their underlying loci that contribute barriers to gene flow. These barrier traits and barrier loci underlie individual barrier effects, by which we mean the contribution that a barrier locus or trait-or some combination of barrier loci or traits-makes to overall isolation. The evolution of strong reproductive isolation ...
متن کاملReinforcement Can Overcome Gene Flow during Speciation in Drosophila
Reinforcement, the strengthening of prezygotic reproductive isolation by natural selection in response to maladaptive hybridization [1-3], is one of the few processes in which natural selection directly favors the evolution of species as discrete groups (e.g., [4-7]). The evolution of reproductive barriers via reinforcement is expected to evolve in regions where the ranges of two species overla...
