Most studies of reinforcement speciation focus on the evolution of assortative mating, but R. A. Fisher argued that migration modification is likely to be a common alternative mechanism. Despite previous models showing that assortative mating and migration modification may both be involved in reinforcement, no one has determined their relative evolutionary importance. This is surprising because understanding the biological conditions favoring these mechanisms may explain why certain pairs of… Expand

Topics from this paper

Mechanisms of reinforcement in natural and simulated polymorphic populations
TLDR
Congruence of the results for allele frequencies versus fixation probabilities suggests that similar patterns of reinforcement are expected during different stages of the speciation process. 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
Is cascade reinforcement likely when sympatric and allopatric populations exchange migrants?
TLDR
The results show that when sympatric and allopatric populations reside in the same environment and only differ in their exposure to maladaptive hybridization, migration between them generally inhibits the evolution of cascade by spreading the reinforcement alleles from sympatry into allop atry and erasing RCD. Expand
THE ROLE OF DIFFERENT REPRODUCTIVE BARRIERS DURING PHENOTYPIC DIVERGENCE OF ISOPOD ECOTYPES
TLDR
It is demonstrated that two recently diverged ecotypes of a freshwater isopod have rapidly developed premating isolation, and this isolation barrier has emerged independently and in parallel in two south Swedish lakes, consistent with ecological speciation theory. Expand
Heterospecific mating interactions as an interface between ecology and evolution
TLDR
An eco‐evolutionary perspective on reproductive interference is developed by integrating ecological and evolutionary processes in a common framework and a number of factors that are likely to influence the relative likelihoods of extinction or RCD are identified. Expand
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
The Genetics and Ecology of Reinforcement
TLDR
Reinforcement, the evolution of prezygotic reproductive barriers by natural selection in response to maladaptive hybridization, is one of the most debated processes in speciation and recent theoretical and empirical work on genetics and ecology of reinforcement suggests it can be overcome. 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
The consequences of phenotypic plasticity for ecological speciation
TLDR
It is found that adaptive plasticity evolves readily in the presence of dispersal between populations from different ecological environments and can either enhance or degrade the potential for divergent selection to form reproductive barriers. Expand
The Role of Ecology in Speciation by Sexual Selection: A Systematic Empirical Review.
TLDR
A recent conceptual framework for examining interactions between mate choice divergence and ecological context was applied to a review of the empirical literature on speciation by sexual selection and revealed that certain traits are consistently associated with certain ecological factors. Expand

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
On the origin of species by sympatric speciation
TLDR
This work uses multilocus genetics to describe sexual reproduction in an individual-based model and considers the evolution of assortative mating, which leads to reproductive isolation between ecologically diverging subpopulations and conforms well with mounting empirical evidence for the sympatric origin of many species. 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. 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
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
THE EVOLUTION OF PREMATING ISOLATION: LOCAL ADAPTATION AND NATURAL AND SEXUAL SELECTION AGAINST HYBRIDS
  • M. Servedio
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 2004
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
Speciation by Natural and Sexual Selection: Models and Experiments
TLDR
It is shown that the geographical context of speciation can be viewed as a form of assortative mating and this provides a framework for interpreting results from laboratory experiments, which are found to agree generally with theoretical predictions about conditions that are favorable to the evolution of prezygotic isolation. 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.

Reproductive isolation caused by visual predation on migrants between divergent environments
  • P. Nosil
  • Biology, Medicine
  • Proceedings of the Royal Society of London. Series B: Biological Sciences
  • 2004
TLDR
Evidence that population divergence in cryptic coloration can also cause reproductive isolation is provided and data indicate that high rates of visual predation on less–cryptic migrants are likely to reduce encounters, and thus interbreeding, between host–associated populations. Expand
Reinforcement: the road not taken
TLDR
It is argued that traveling down The Road Not Taken (apologies to Frost), that is, taking into consideration mating system and patterns of gamete utilization, leads to novel and more precise predictions of the circumstances under which reinforcement should occur. Expand
