Detailed studies of reproductive isolation and how it varies among populations can provide valuable insight into the mechanisms of speciation. Here we investigate how the strength of premating isolation varies between sympatric and allopatric populations of threespine sticklebacks to test a prediction of the hypothesis of reinforcement: that interspecific mate discrimination should be stronger in sympatry than in allopatry. In conducting such tests, it is important to control for ecological… Expand
REPRODUCTIVE CHARACTER DISPLACEMENT OF MALE STICKLEBACK MATE PREFERENCE: REINFORCEMENT OR DIRECT SELECTION?
TLDR
The contrast in male behavior suggests that egg predation has shaped male preferences, and direct selection is likely that it has been important in building up reproductive isolation between limnetic and benthic sticklebacks. Expand
Speciation and the evolution of mating preferences in threespine sticklebacks (Gasterosteus aculeatus)
TLDR
It is determined that the mate preferences of the small species have shifted from preferring large females to preferring small females due either to selection against hybrids (reinforcement), or to egg predation by the larger benthic species. Expand
Lack of Assortative Mating Between Incipient Species of Stickleback from a Hybrid Zone
TLDR
It is inferred that postmating isolation has preceded the evolution of premating isolation (assortative mating) in this population of sticklebacks and hybridisation between anadromous and freshwater stickleback from the River Tyne, Scotland, occurs readily, and that sexual selection is unlikely to contribute to premates isolation.

BODY SIZE, NATURAL SELECTION, AND SPECIATION IN STICKLEBACKS
  • L. Nagel, D. Schluter
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 1998
TLDR
Interspecific mate preferences in sympatric sticklebacks appears to be dominated by body size, implicating natural selection in the origin of species. Expand
Reproductive character displacement between the closely related freshwater snails Lymnaea peregra and L. ovata
TLDR
It is found that snails from the sympatric location avoided mating with the opposite species, while allopatric snails showed less discrimination against the oppositespecies, supporting the view that reproductive isolation may commonly be reinforced by selection when two closely related taxa occur in sympatry.

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
Olfactory perception of mates in ecologically divergent stickleback: Population parallels and differences
TLDR
The preference for conspecific over heterospecific odours, although not strong, may still contribute to reproductive isolation in sympatric sticklebacks, particularly through interactions with other senses and environmental properties. Expand
Mate choice among sympatric fur seals: female preference for conphenotypic males
TLDR
It is found that extra-territory inseminations were significantly more prevalent when territorial males and resident females were of different phenotype than when of similar phenotype, but mtDNA genotype had no effect on the rate of ETIs. Expand
SEXUAL SELECTION AGAINST HYBRIDS BETWEEN SYMPATRIC STICKLEBACK SPECIES: EVIDENCE FROM A FIELD EXPERIMENT
TLDR
Sexual selection, like other mechanisms of postzygotic isolation between young sister species, may be stronger in a wild setting than in the laboratory because of habitat‐specific selection pressures. Expand
Experimental evidence for asymmetric mate preference and aggression: behavioral interactions in a woodrat (Neotoma) hybrid zone
TLDR
Patterns of mate choice in this woodrat system appear to be strongly impacted by body size and aggressive behavior, and multiple isolating mechanisms contribute to the rate of genetic exchange between these species when they come into contact, and that these mechanisms are the result of selection on traits that are important in a range of ecological and reproductive interactions.

A TEST FOR SEXUAL SELECTION ON HYBRIDS OF TWO SYMPATRIC STICKLEBACKS
TLDR
This experiment found no evidence for a hybrid mating disadvantage, and interpreted that if sexual selection against hybrids is present in the wild, then some factor that biases encounter rates between hybrids and parental species (e.g., habitat selection) is necessary to produce it. Expand

Ecology and evolution of sympatric sticklebacks (Gasterosteus): mate choice and reproductive isolation in the Enos Lake species pair
TLDR
Field observations, mate choice experiments, and courtship experiments were conducted to determine if courtship behaviour contributes to reproductive isolation between these two species of sticklebacks. Expand
How Often Does Sympatry Affect Sexual Isolation in Drosophila?
  • M. Noor
  • Biology, Medicine
  • The American Naturalist
  • 1997
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
Ecological Character Displacement and Speciation in Sticklebacks
TLDR
Evidence of ecological character displacement among species of threespined sticklebacks that inhabit small lakes of coastal British Columbia is presented and the possibility that competition for food has played a critical role in the divergence between species is considered. Expand
Adaptive Radiation in Sticklebacks: Size, Shape, and Habitat Use Efficiency
TLDR
The hypothesis that different traits are favored in different habitats, and that adaptation to one habitat has occurred at the expense of feeding rate in the other, is supported. Expand
Adaptive Radiation in Sticklebacks: Trade‐Offs in Feeding Performance and Growth
TLDR
It is argued that steep trade-offs in fitness along the littoral-open- water habitat gradient have two further consequences: first, they may cause Hybrids to have low fitness, allowing Benthics and Limnetics to coexist in the absence of perfect premating isolation between them, and second, they May promote ecological character dis- placement. 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
“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. Expand
Evolution of Male Pheromones in Moths: Reproductive Isolation Through Sexual Selection?
TLDR
Evidence is given that male courtship pheromones have evolved within the context of sexual isolation as an adaptive response to mating mistakes between differentially adapted populations; however, distinct from the natural selection model of Dobzhansky, this report suggests the mechanism for change to be sexual selection.
