The generation of premating isolation given partial or complete postzygotic isolation between populations is termed reinforcement or, in the case of complete isolation, reproductive character displacement. In this study we use computer simulations and a multilocus genetic model to reevaluate the theory of reinforcement. We consider the evolution of female preferences for a male secondary sexual trait. If the populations differ in mean female preference, there is direct selection on the… Expand
Speciation by reinforcement: a model derived from studies of Drosophila.
TLDR
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.

THE EVOLUTION OF PREMATING ISOLATION: LOCAL ADAPTATION AND NATURAL AND SEXUAL SELECTION AGAINST HYBRIDS
Although reinforcement is ostensibly driven by selection against hybrids, there are often other components in empirical cases and theoretical models of reinforcement that may contribute to prematingExpand
Reproductive isolation driven by the combined effects of ecological adaptation and reinforcement
TLDR
These findings demonstrate the joint effects of reinforcement, ecological adaptation and gene flow on progress towards speciation in the wild in Timema cristinae walking-stick insects. Expand
Sympatric speciation by sexual selection
TLDR
It is shown that variation in a male secondary sexual character with two conspicuous extremes and the corresponding variance in female mating preference around no preference may jointly evolve into bimodal distributions with increasing modal divergence of the male and female traits, pulling a population apart into two prezygotically isolated populations.

The reinforcement of mating preferences on an island.
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 aExpand
Conflict over fertilization underlies the transient evolution of reinforcement
TLDR
A population genetic model of interspecific conflict over reinforcement, inspired by ‘gametophytic factors’, is developed, which demonstrates that this conflict results in the transient evolution of reinforcement – after female preference for a conspecific gamete trait rises to high frequency, male traits adaptively introgress into the other population. Expand
Assortative mating in hybrid zones is remarkably ineffective in promoting speciation
TLDR
Simulation of secondary contact between two populations to examine effects of pre- and postzygotic isolation in preventing blending, which results prompt a questioning of the concept of partial prezygosis isolation, since it is not very isolating unless there is also postzyGotic isolation. Expand

TLDR
It is tentatively predicted that sexual conflict will typically result in a higher rate of speciation in ' female-win' clades, that females will be responsible for premating isolation through reinforcement, and that 'female- win' populations will be less genetically diverse. Expand
Speciation by Natural and Sexual Selection: Models and Experiments
TLDR
It is shown that the geographical context of speciation can be viewed as a form of assortative mating and this provides a framework for interpreting results from laboratory experiments, which are found to agree generally with theoretical predictions about conditions that are favorable to the evolution of prezygotic isolation. Expand
Speciation by sexual selection in hybridizing populations without viability selection
TLDR
This model does not require viability selection for male sexual traits, selection against unfit hybrids or disruptive selection for ecological traits, and assumes that females exhibit mating preferences based on male secondary sexual characters. Expand

TLDR
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. Expand
A Theoretical Investigation of Speciation by Reinforcement
TLDR
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.

TLDR
The formation of new species must involve the evolution of barriers to gene flow within existing species, but how these barriers arise remains a problem and recent studies suggest serious limitations on the efficacy of reinforcing selection and a lack of well-substantiated examples. Expand

TLDR
A variety of theories have been proposed for the evolution of female mating preferences when paternal genes are the only contribution males make to their offspring, and most require that the fitness of a female's offspring somehow be predictable from the phenotype of a prospective mate. Expand

TLDR
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. Expand

LABORATORY EXPERIMENTS ON SPECIATION: WHAT HAVE WE LEARNED IN 40 YEARS?
TLDR
The role of geographical separation in generating allopatry has been overemphasized in the past and its role in generating diminished gene flow in combination with strong, discontinuous, and multifarious divergent selection, has been largely unappreciated. Expand

TLDR
The practical conclusion is that migration must be very small in order for the release of sterile males to be effective on suppressing numbers of adults, while more migration can be tolerated if, as in many agricultural pests, immature stages are the object of concern. Expand
Sexual selection when the female directly benefits
TLDR
Using a quantitative genetic model, it is shown how female preferences for male traits that indicate condition can evolve, even if the male traits themselves have deleterious effects on both the male and the female's fecundity. Expand
