The results suggest that the speciation of a peripheral isolate, which undergoes essentially one‐way migration, may be difficult to complete if secondary contact occurs before reproductive isolation is fully developed.

We develop a haploid model for the reinforcement of female mating preferences on an island that receives migrants from a continent. We find that preferences will evolve to favor island males under a…

Reinforcement is found to occur much more easily in a two-island assortative mating model than in any of the other three models, implying that species recognition in the context of mating may evolve particularly easily when it targets cues that are favored by natural selection in each population.

This work compares models in which evolutionary changes in theCline spread out to affect dynamics in core populations with models where core populations are insulated from changes that occur within the cline.

The effects that sexual selection, long hypothesized to drive the divergence of distinct traits used in mate choice, can play in the evolution of such traits in a partially isolated peripheral population are explored.
Three Modes of Adaptive Speciation in Spatially Structured Populations
- A. RettelbachM. KoppU. DieckmannJ. Hermisson

Biology, Environmental Science
This work incorporates both frequency-dependent competition and local adaptation into a single model and finds that the two mechanisms can operate together, leading to a third speciation mode in which speciation is initiated by selection against maladapted migrants but completed by within-deme competition in a distinct second phase.

Biology, Environmental Science
It is demonstrated that sexual selection created by assortative mating can explain steep transitions in mating-trait loci without generalizing to genome-wide reproductive isolation and further emphasizes the importance of mating-Trait architecture for spatio–temporal hybrid-zone dynamics.
Divergent Outcomes of Reinforcement Speciation: The Relative Importance of Assortative Mating and Migration Modification
- Roman YukilevichJ. True
- 2006
Biology
The results reveal that assortative mating may evolve faster and under a broader range of biological conditions than migration modification, however, direct evolutionary interactions favor migration modification when populations experience strong divergent selection.
Evolution with Stochastic Fitness and Stochastic Migration
- S. RiceA. Papadopoulos

Biology, Mathematics
An exact equation for directional evolution is derived, essentially a stochastic Price equation with migration, that encompasses all processes contributing to directional change in an open population and shows that increasing the variance in migration rates reduces the impact of migration relative to selection.
Mechanisms of reinforcement in natural and simulated polymorphic populations

Congruence of the results for allele frequencies versus fixation probabilities suggests that similar patterns of reinforcement are expected during different stages of the speciation process.
Migration-Selection Balance at Multiple Loci and Selection on Dominance and Recombination
- Alexey YanchukovS. Proulx
- 2014
Biology, Mathematics
This novel method gives a close approximation to the simulation with all possible multilocus genotypes considered and finds that the modifiers of the (i) type are able to invade faster than the type (ii) modifier, however, this result only applies in the strong selection/low migration/low recombination scenario.

Computer simulations and a multilocus genetic model are used to reevaluate the theory of reinforcement and consider the evolution of female preferences for a male secondary sexual trait and the likelihood of extinction is lowered.

A Theoretical Investigation of Speciation by Reinforcement

Biology
A closer examination of the reinforcement model of speciation using a computer simulation reveals that there are a number of implicit assumptions necessary for reinforcement to work, suggesting that speciation by reinforcement is not nearly as prevalent as much of the biological literature suggests.

A specific model is put forward in which mating behavior is determined by additive gene contributions in both sexes, and the strength of mating attraction is maximized when mating "scores" in the two sexes are equalized.
Speciation by reinforcement: a model derived from studies of Drosophila.
It is suggested that an increase in the level of female mating discrimination can yield reinforcement without further divergence of either male characters or female preferences, and selection on mating discrimination is a viable mechanism for reinforcement and may allow speciation under less stringent conditions than selection on female preference.

It is invalid to conclude that a monotonic cline for reproductive isolation gives a priori evidence of its evolution in allopatry, but the existence of inverse clines in isolating mechanisms strongly suggests the evolution of isolation in sympatry.

Mechanisms for clinal speciation first outlined in genetic terms by Fisher (1930) are reinvestigated and the latter mechanism is potentially much more powerful for initiating sexual isolation and character divergence along a cline than is selection against hybridization.

A theory is suggested according to which the development of isolating mechanisms follows, rather than accompanies, that of the adaptive complexes themselves, which suggests that speciation is meant the fixation of discontinuity among organisms.

Two genetic and molecular analyses suggest the presence of a major sterility factor from D. mauritiana, which is named Odysseus (Ods), in the cytological interval of 16D, and formalize three criteria for inferring the existence of amajor gene within an introgression.
