Reinforcement is an increase in premating reproductive isolation between taxa resulting from selection against hybrids. We present a model of reinforcement with a novel type of selection on female mating behavior. Previous models of reinforcement have focused on the divergence of female mating preferences between nascent species. We suggest that an increase in the level of female mating discrimination can yield reinforcement without further divergence of either male characters or female… Expand
The Genetics of Speciation by Reinforcement
TLDR
It is shown that reinforced mating discrimination is inherited as a dominant trait, exhibits variability within species, and may be influenced by a known set of candidate genes involved in olfaction, the first high-resolution genetic study of variation within species for female mating discrimination that is enhanced by natural selection.

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
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
Asymmetrical Reinforcement and Wolbachia Infection in Drosophila
TLDR
It appears that there are multiple ways by which Wolbachia endosymbionts may directly and indirectly contribute to reproductive isolation and speciation. 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
THE EVOLUTION OF PREMATING ISOLATION: LOCAL ADAPTATION AND NATURAL AND SEXUAL SELECTION AGAINST HYBRIDS
  • M. Servedio

TLDR
It is found that selection against hybrids may play a small role in driving preference evolution in a reinforcement model where the mating cue is separate from loci causing hybrid incompatibilities. Expand
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.

  • 1998
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
Natural selection and divergence in mate preference during speciation
TLDR
Understanding of the evolution of sexual isolation can be enhanced by isolating the roles of diverse ecological and evolutionary processes, and it is shown that sexual isolation involves, at least in part, olfactory communication. Expand
INCIPIENT SPECIATION BY SEXUAL ISOLATION IN DROSOPHILA MELANOGASTER: VARIATION IN MATING PREFERENCE AND CORRELATION BETWEEN SEXES
TLDR
Surfacing four populations in southern Africa and additional cosmopolitan lines, it is observed that extensive genetic variation in sexual characters as well as strong correlation between sexes are observed. Expand

SPECIATION BY REINFORCEMENT OF PREMATING ISOLATION
  • L. Liou, T. Price
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 1994
TLDR
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. Expand

TLDR
The models elucidate genetic mechanisms that can initiate or contribute to rapid speciation by sexual isolation and divergence of secondary sexual characters in polygamous species. Expand
Mating Choice in Crosses between Geographic Populations of Drosophila pseudoobscura
TLDR
The literature was reviewed to find tests of mating behavior in crosses between allopatric strains of Droso-phila species and crosses between subspecies were excluded, since in Drosophila, unlike many other animal groups, named subspecies are likely to be well advanced toward full speciation.

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
SEXUAL SELECTION AND THE EVOLUTION OF FEMALE CHOICE

TLDR
The primary conclusion of the present paper is that the initial selective advantages for the female preference assumed by Fisher, O'Donald, and many later authors are not necessary for either the origin or subsequent elaboration of mating preferences for traits associated with reduced survivorship. Expand
Speciation driven by natural selection in Drosophila
TLDR
The results suggest that females of D. pseudoobscura evolved increased sexual isolation from their sibling species, D. persimilis, by natural selection against maladaptive hybridization. Expand

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
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.
