The Kaneshiro model proposes a role for sexual selection in peripatric speciation. During population bottlenecks, derived males lose attractive traits and become discriminated against by ancestral females, whereas derived females are selected to be less choosy. This permits novel mate choice cues to evolve in derived populations. In a quantitative analysis of laboratory experiments, we show that bottlenecked males have indeed become less attractive, but females have not lost their ancestral…

Drift and selection entwined: asymmetric reproductive isolation in an experimental niche shift
TLDR
Strong selection in the derived (corn) population appears to have decreased population size to the extent that genetic drift led to the fixation of deleterious alleles that reduced corn-evolved male fitness, and asymmetric pre-mating isolation arose because of this drift-induced maladaptation.
DIVERGENT ENVIRONMENTS AND POPULATION BOTTLENECKS FAIL TO GENERATE PREMATING ISOLATION IN DROSOPHILA PSEUDOOBSCURA

    Evolution; international journal of organic evolution
  • 2003
TLDR
The novel environment did not cause the evolution of any premating isolation and it reduced the likelihood of speciation through its effects on male mating success, both as a plastic response to this environment and as a result of environment-dependent inbreeding effects in the bottlenecked populations.

Song divergence at the edge of Amazonia: an empirical test of the peripatric speciation model
TLDR
These findings are consistent with the idea that vocal divergence arising in small populations at the edge of Amazonia may result in partial reproductive isolation when contact is resumed, and suggest the possibility that song divergence in peripatry may act as a barrier to gene flow in suboscines.
Peripatric speciation
Peripatric speciation is a mode of speciation in which a new species is formed from an isolated peripheral population.[1]:105 Since peripatric speciation resembles allopatric speciation, in that…
Divergence at the edges: peripatric isolation in the montane spiny throated reed frog complex
TLDR
In this case study, peripatric speciation appears to be an important driver of diversity within the EABH biodiversity hotspot, implying it could be a significant speciation mechanism in highly fragmented ecosystems.
REPRODUCTIVE ISOLATING MECHANISMS BETWEEN TWO SYMPATRIC SIBLING SPECIES OF SEA SNAKES
TLDR
Study of two sibling species of amphibious sea snakes on the island of Efate shows that the separation between these two taxa is maintained by species‐specific cues that control male courtship, and suggests the possibility of sympatric speciation.
Symmetrical discrimination despite weak song differentiation in 2 suboscine bird sister species
TLDR
This study performs song play-back experiments on males of a long-diverged sister pair of Neotropical Suboscine species, the squamate antbird and the whitebibbed antbird, which occur in parapatry in the Atlantic Forest and that overlap extensively in song variation.
Molecular phylogenetics of the hummingbird genus Coeligena.
TLDR
The results indicate the importance of geographic isolation for speciation in the Andean hummingbird genus Coeligena and the potential interaction between isolation and sexual selection to promote diversification.
Song perception among incipient species as a mechanism for reproductive isolation
TLDR
Results indicate that a certain degree of reproductive isolation between the two taxa already exists; consistently with genetic data and with the peculiar pattern of distribution; this suggests that the twoTaxa have reached species status.

Laboratory environments are not conducive for allopatric speciation
TLDR
It is suggested that allopatric speciation experiments are more likely to yield conclusive results under divergent selection than under drift, and points to the benefits of large populations and many generations.
SEXUAL ISOLATION, SPECIATION AND THE DIRECTION OF EVOLUTION
  • K. Kaneshiro
  • Biology, Medicine
    Evolution; international journal of organic evolution
  • 1980
TLDR
This paper elaborates the hypothesis proposed by Kaneshiro (1976) and proposes a uni-directional phylogeny for the six populations of the grimshawi complex of species.
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.
CHASE‐AWAY SEXUAL SELECTION: RESISTANCE TO “RESISTANCE”
TLDR
The model's two central assumptions are: (1) male traits "seduce" females into mating in a suboptimal way; and (2) selection thus favors female "resistance" to these traits, which makes predictions that can be readily tested in future studies.
SELECTION FOR SEXUAL ISOLATION BETWEEN GEOGRAPHIC FORMS OF DROSOPHILA MOJAVENSIS. I. INTERACTIONS BETWEEN THE SELECTED FORMS
  • H. R. Koepfer
  • Biology, Medicine
    Evolution; international journal of organic evolution
  • 1987
TLDR
Drosophila mojavensis comprises three geographic forms occurring in the United States, the Baja California peninsula, and mainland Mexico, and response to selection was highly asymmetrical in that isolation was very high between selected peninsular males and mainland females, but nonexistent between selected mainland males andPeninsular females.
SINGLE FOUNDER‐FLUSH EVENTS AND THE EVOLUTION OF REPRODUCTIVE ISOLATION
TLDR
Results indicate that none of 50 independent founder‐flush lines evolved significant assortative mating relative to the control population, which suggests a diminished emphasis on population bottlenecks in speciation of D. melanogaster and perhaps in general.
The Effects of Selection and Bottlenecks on Male Mating Success in Peripheral Isolates
TLDR
Peripheral isolates formed from single founder events may be expected to show decreased levels of additive genetic variance, altered allele frequencies, and increased homozygosity relative to the preisolation population.
FOUNDER‐FLUSH SPECIATION IN DROSOPHILA PSEUDOOBSCURA: A LARGE‐SCALE EXPERIMENT
TLDR
The results do not support the claim that the founder‐flush‐crash model identifies conditions very likely to result in speciation events, and it is concluded that although founder events may occasionally lead to the evolution of assortative mating and hence to speciation, the claims are not supported.
Adaptation of Drosophila willistoni experimental populations to extreme pH medium
TLDR
A significant sexual preference was observed for homogamic insemination among populations derived from the centre of the species distribution than the ones collected near the margin of its distribution range, which may be due to their significantly greater chromosomal and genie polymorphism.
An Experiment Testing Two Hypotheses of Speciation
TLDR
The results of this experiment and previous, related ones support the view that either genetic drift or selection is by itself sufficient to produce reproductive isolation as a pleiotropic by-product and help establish sexual isolation in Drosophila simulans.
