The pattern of greater species mating discrimination between sympatric taxa than between allopatric taxa has been attributed to the strengthening of mate discrimination to avoid maladaptive hybridization. This process, termed reinforcement, has been highly contentious, particularly with regard to its role in speciation. Here, I review some recent studies of reinforcement, discuss alternative explanations for the pattern of greater species discrimination in sympatric taxa, and point to some new… Expand
Implications for the Evolution of Prezygotic Isolation in Sympatry and Beyond
TLDR
Data is reviewed on the genetic basis of female preferences, connections between prezygotic isolation between species and within-species sexual selection, and the role of habitat versus mate preference in reinforcement, why they are important for understanding speciation. Expand
Reinforcement’s incidental effects on reproductive isolation between conspecifics
TLDR
It is suggested that CER is likely if (1) the rate of gene flow between conspecific populations is low; (2) divergent selection acts on phenotypes involved in reinforcement between sympatric and allopatric populations; and (3) the genetic response to reinforcement differs among conspespecific populations subject to parallel reinforcing selection. Expand
The role of reinforcement in speciation: Theory and data
TLDR
It is concluded that reinforcement has probably not been looked for where it is most likely to occur, and many further areas of study are pinpointed that may ultimately provide a strong assessment of the importance of reinforcement in speciation. Expand
Reinforcement as an initiator of population divergence and speciation
TLDR
How this process can occur, the conditions under which it is most likely to occur, and the empirical data needed to evaluate the hypothesis that reinforcement can initiate speciation are described are described. Expand
Evidence of Reinforcement of Premating Isolation Between Two Species of the Genus Ochthebius (Coleoptera: Hydraenidae)
TLDR
By analyzing species composition of mating couples collected in sympatric localities, it is shown the existence of strong assortative mating between the two species in nature and Reinforcement is suggested as the most parsimonious hypothesis to explain the evolution of discriminative mate recognition systems occurring among O. quadricollis and Ochthebius sp. Expand
Limits to Speciation Inferred from Times to Secondary Sympatry and Ages of Hybridizing Species along a Latitudinal Gradient
TLDR
It is estimated that secondary sympatry takes on the order of millions of years following population splitting and hence could impose an important limit on the rate of range expansion, thereby limiting further rounds of species formation. Expand
Diversification of Conspecific Signals in Sympatry: Geographic Overlap Drives Multidimensional Reproductive Character Displacement in Frogs
  • E. Lemmon
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 2009
TLDR
Patterns of acoustic signal divergence in two- and three-species assemblages of chorus frogs (Pseudacris) suggest that interactions between species can promote diversification within species, potentially contributing to reproductive isolation among conspecific populations. Expand
Tracing reinforcement through asymmetrical partner preference in the European common vole Microtus arvalis
TLDR
The detected partner preferences are consistent with asymmetrical reinforcement of pre-mating reproductive isolation mechanisms in the European common vole and with earlier results suggesting that hybridization is more detrimental to the Western lineage. Expand
Fine‐scale geographic patterns of gene flow and reproductive character displacement in Drosophila subquinaria and Drosophila recens
TLDR
Reinforcement within D. subquinaria is effective at maintaining species boundaries, but even when reinforcing selection is strong it may not always result in a pattern of strong reproductive character displacement due to variation in the frequency of hybridization and gene flow from neighbouring populations.

Natural Selection Reinforces Speciation in a Radiation of Neotropical Rainforest Plants
  • K. Kay, D. Schemske

  • 2008
TLDR
These studies indicate that crossing barriers prevent potentially maladaptive hybridization and effectively reinforce the speciation process, adding to mounting evidence for reinforcement from animal studies and showing that plant speciation may also involve complex mate recognition systems. Expand

A sexually selected character displacement in flycatchers reinforces premating isolation
TLDR
In populations where two species coexist, it is shown that female choice selects for a divergence in male plumage colour and that the resulting character displacement reduces the frequency of hybridization. Expand
REINFORCEMENT OF STICKLEBACK MATE PREFERENCES: SYMPATRY BREEDS CONTEMPT
TLDR
Results are consistent with the hypothesis that female mate preferences have evolved as a response to reduced hybrid fitness (reinforcement), although direct effects of sympatry or a biased extinction process could also produce the pattern. 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
How Often Does Sympatry Affect Sexual Isolation in Drosophila?

TLDR
The Coyne and Orr (1989, 1997) data sets clearly show that sympatry influences prezygotic isolation, the frequency with which interactions among sympatric taxa cause increases in prezyGotic isolation is not clear and the comparative method may be used to estimate more accurately the frequency of increases. 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.

“PATTERNS OF SPECIATION IN DROSOPHILA” REVISITED
  • J. Coyne, H. A. Orr
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 1997
TLDR
The data from Drosophila are unique-and are likely to remain so-because of the large number of crossable species and the ease of estimating sexual and postzygotic isolation in the laboratory, and some estimates of reproductive isolation and phylogenetic relatedness when better data became available are revised.

The process of speciation in birds can be inferred from the pattern of diversification on islands, especially in archipelagos. The basic model is one of initial differentiation of allopatricExpand
Assortative mating across a hybrid zone in Chorthippus parallelus (Orthoptera: Acrididae)
TLDR
It is shown that, with virgin insects, such assortment decreases as one approaches the centre of the zone in C. parallelus, and it is argued that other tests of the model may be more appropriate for stable hybrid zones. 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.

CHARACTER DISPLACEMENT FOR SEXUAL ISOLATION BETWEEN DROSOPHILA MOJAVENSIS AND DROSOPHILA ARIZONENSIS
TLDR
Evidence for reproductive character displacement in natural populations is poor and controversial, and it is felt that many of these problems could be avoided if one could demonstrate character displacement for sexual isolation. Expand
