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
Magic traits in speciation: 'magic' but not rare?
TLDR
It is illustrated that magic traits can be produced by a variety of mechanisms, including ones in which reproductive isolation arises as an automatic by-product of adaptive divergence. Expand
Species delimitation in systematics: inferring diagnostic differences between species

  • 7 April 2000
TLDR
It is argued that determining whether diagnostic characters are truly fixed with certainty is generally impossible with finite sample sizes and it is shown that sample sizes of hundreds or thousands of individuals may be necessary to have a reasonable probability of detecting polymorphisms in diagnostic characters at frequencies approaching zero.

The impact of learning on sexual selection and speciation.
TLDR
It is pointed out that the context of learning, namely how and when learning takes place, often makes a crucial difference to the predicted evolutionary outcome. Expand
REINFORCEMENT AND THE GENETICS OF NONRANDOM MATING

  • 1 February 2000
TLDR
Reinforcement is found to occur more often under the preference model than the assortative mating model, thus reversing the trend from the two‐island models, and patterns of population subdivision may play a role in determining what types of premating isolation may evolve. Expand
Frequency-Dependent Selection and the Evolution of Assortative Mating
TLDR
The conditions under which selection favors the evolution of assortative mating, thereby reducing gene flow between sympatric groups, are analyzed using a general model of selection, which allows fitness to be frequency dependent. Expand
THE EVOLUTION OF PREMATING ISOLATION: LOCAL ADAPTATION AND NATURAL AND SEXUAL SELECTION AGAINST HYBRIDS
  • M. Servedio
  • Biology, Medicine
  • Evolution; international journal of organic…
  • 1 May 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
Sex Chromosome-Linked Species Recognition and Evolution of Reproductive Isolation in Flycatchers
TLDR
It is demonstrated that species recognition is inherited on the Z chromosome, which is also the known location of species-specific male plumage traits and genes causing low hybrid fitness, suggesting that the sex chromosomes may be a hotspot for adaptive speciation. Expand
POPULATION GENETIC MODELS OF MALE AND MUTUAL MATE CHOICE

  • Biology, Medicine
  • Evolution; international journal of organic…
  • 1 April 2006
TLDR
Unless males with a preference are able to increase their overall courtship output, male preference will be lost, and it becomes possible for a male preference to be maintained, regardless of whether preferences between the sexes are pleiotropic or controlled by separate loci. Expand
The Role of Sexual Selection in Local Adaptation and Speciation
TLDR
It is concluded that although there is ample evidence that sexual selection contributes to the speciation process, it is very likely to do so only in concert with natural selection. Expand
