In a seminal article and its follow-up, Coyne and Orr (1989, 1997) found greater prezygotic (primarily sexual) reproductive isolation in sympatric Drosophila species pairs than in allopatric pairs of similar genetic divergence. Several processes can explain this observed pattern. For example, natural selection could have strengthened the existing mating discrimination between sympatric species to reduce either maladaptive hybridization (Dobzhansky 1940) or interference of mate recognition… Expand
Rapid sexual and genomic isolation in sympatric Drosophila without reproductive character displacement
TLDR
Speciation in the Drosophila athabasca species complex is at least an order of magnitude older than previously assumed, and it is suggested that these semispecies should be given full species status and adopted new nomenclature. Expand
Sexual imprinting and speciation in two Peromyscus species
TLDR
It is demonstrated that sexual imprinting contributes to reproductive isolation that reduces hybridization between otherwise interfertile species, supporting the role for learning in mammalian speciation. Expand
Sexual imprinting and speciation between two Peromyscus species
TLDR
It is demonstrated that sexual imprinting contributes to reproductive isolation that reduces hybridization between otherwise interfertile species, supporting the role for learning in mammalian speciation. Expand
Pervasive reinforcement and the role of sexual selection in biological speciation.
TLDR
It is shown that in birds, divergence in song and plumage in allopatry corresponds poorly with whether species mate assortatively in hybrid zones and argued that many other factors besides trait divergence affect propensity to hybridize, including rarity of conspecific mates and choice based on territory rather than male traits.

ASYMMETRICAL PATTERNS OF SPECIATION UNIQUELY SUPPORT REINFORCEMENT IN DROSOPHILA
  • Roman Yukilevich
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 2012
TLDR
It is suggested that reinforcement plays a key role in Drosophila speciation by uncovering new patterns explicitly predicted by reinforcement and showing that concordant isolation asymmetries in sympatry are likely unique signatures of reinforcement. 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
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
Reproductive Character Displacement Drives Diversification of Male Courtship Songs in Drosophila
TLDR
The widespread pattern of character displacement implies that allopatric divergence due to processes like sexual selection are very slow relative to sympatric processes such as reinforcement and reproductive interference in driving song diversification across Drosophila. Expand
Reproductive character displacement of female mate preferences for male cuticular hydrocarbons in Drosophila subquinaria
  • H. Rundle, K. Dyer
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 2015
TLDR
It is found that the direction of linear sexual selection varies significantly between populations that are sympatric versus allopatric with D. subquinaria, and differences in preference partially align with existing differences in cuticular hydrocarbons and patterns of sexual isolation. Expand
The evolution of male and female mating preferences in Drosophila speciation *
TLDR
The results revealed that male and female mate preferences are both ubiquitous in Drosophila but evolved largely independently, suggesting different underlying evolutionary and genetic mechanisms, and implies that evolved female preferences may reduce selection for further divergence of male courtship preferences in sympatry.

  • 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. Expand
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
DIRECT OBSERVATION OF SEXUAL ISOLATION BETWEEN ALLOPATRIC AND BETWEEN SYMPATRIC STRAINS OF THE DIFFERENT DROSOPHILA PAULISTORUM RACES
TLDR
Drosophila paulistorum is indeed a superspecies composed of six races or subspecies or incipient species, and this situation is of interest precisely because these six may be considered about equally legitimately as very distinct races or as very closely related species. Expand
Host fidelity is an effective premating barrier between sympatric races of the apple maggot fly.
TLDR
The results verify that host-associated adaptation can produce reproductive isolation as a correlated character (a key premise of sympatric speciation) and represents one of the few or perhaps only example in animals where the intra-specific isolating effects of specific phenotypes have been quantified in nature. Expand
Ecological Speciation in Postglacial Fishes
TLDR
It is argued that knowledge of ecological environments is essential to understanding the origin of species in adaptive radiation, and perhaps more generally to complement (and perhaps transform) traditional genetic approaches to speciation. 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.

Speciation and hybridization in island birds
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

  • Evolution; international journal of organic evolution
  • 1997
TLDR
The genetic basis of sexual isolation using male hybrids of Drosophila pseudoobscura and D. persimilis was investigated, and although there was an X‐chromosome component to mating success, its magnitude was not disproportionately large when compared with the proportion of the genome contained on this chromosome.

Natural hybridization in Drosophila, with special reference to species from Hawaii
TLDR
It is suggested that the dynamics of sexual selection plays an important role in permitting occasional hybridization in nature and that this allows limited introgression without destroying the genetic integrity of the species. Expand
