Adaptive speciation with gene flow via the evolution of assortative mating has classically been studied in one of two different scenarios. First, speciation can occur if frequency-dependent competition in sympatry induces disruptive selection, leading to indirect selection for mating with similar phenotypes. Second, if a subpopulation is locally adapted to a specific environment, then there is indirect selection against hybridizing with maladapted immigrants. While both of these mechanisms have… Expand

Speciation in peripheral populations: effects of drift load and mating systems
TLDR
This study identifies two additional problems of peripatric speciation, as compared to the parapatric case, that may impede the completion of the speciation process for most parameter regions. Expand
Geography, assortative mating, and the effects of sexual selection on speciation with gene flow
  • M. Servedio

  • 2016
TLDR
This work focuses on how two factors, the geographic context of speciation and the mechanism leading to assortative mating, interact to alter the effect that sexual selection through mate choice has on speciation. Expand
Three-phase transitions to reproductive isolation: The roles of utilization mismatch and residual selection
TLDR
This work studies three types of mismatch-driven speciation, resulting from incongruences between the shapes of resource distributions and competition kernels, low numbers of loci, and premature cessations of the first phase’s variance expansion. Expand
The Roles of Sexual and Viability Selection in the Evolution of Incomplete Reproductive Isolation: From Allopatry to Sympatry
TLDR
This study investigates the evolution of incomplete reproductive isolation by sexual selection in scenarios ranging from sympatry to allopatry, to examine how these mechanisms interact and proposes a new avenue for understanding the diversity in levels of reproductive isolation within and across species. Expand
The Limits to Parapatric Speciation II: Strengthening a Preexisting Genetic Barrier to Gene Flow in Parapatry
TLDR
It is shown that the accumulation of genetic incompatibilities in the presence of gene flow is a complex process, where new mutations can either strengthen or destroy a preexisting barrier. Expand
The Limits to Parapatric Speciation II: Strengthening a Preexisting Genetic Barrier to Gene Flow in Parapatry
TLDR
It is concluded that migration is highly effective at disrupting the so-called “snowball effect”, the accelerated accumulation of DMIs that has been described for allopatric populations en route to reproductive isolation. Expand
Divergence and evolution of assortative mating in a polygenic trait model of speciation with gene flow
TLDR
This analysis reveals the existence of sharp thresholds of assortment strength, at which divergence increases dramatically, and shows that the ES assortment strength has an intermediate value under a range of migration‐selection parameters, even in diverged populations, due to subtle effects which depend sensitively on the extent of phenotypic variation within these populations. Expand
The effects of sexual selection on trait divergence in a peripheral population with gene flow
TLDR
The effects that sexual selection, long hypothesized to drive the divergence of distinct traits used in mate choice, can play in the evolution of such traits in a partially isolated peripheral population are explored. Expand
The evolution of partial reproductive isolation as an adaptive optimum
TLDR
It is argued that the evolution of partial reproductive isolation is of great interest in its own right and matches empirical findings that ongoing hybridization is taxonomically widespread and presents the mechanisms by which it can be a stable evolutionary endpoint. Expand
Mechanisms of Assortative Mating in Speciation with Gene Flow: Connecting Theory and Empirical Research
TLDR
By providing a clear framework for mating rules and how these rules affect speciation through maintaining or eroding barriers to gene flow among closely related species or populations, this work hopes to inspire greater alignment in the ways that both theoreticians and empiricists study mating rules.

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.

When is sympatric speciation truly adaptive? An analysis of the joint evolution of resource utilization and assortative mating
  • J. Ripa
  • Biology
  • Evolutionary Ecology
  • 2008
TLDR
This work presents a complete analysis of the whole speciation process by allowing for the simultaneous evolution of the branching ecological trait as well as a continuous trait controlling mating behaviour, and shows how the joint evolution can be understood in terms of a gradient landscape. Expand
An Analytically Tractable Model for Competitive Speciation
TLDR
The approach provides a mechanistic understanding of several phenomena that have been found in previous models and demonstrates how even in a simple model, the evolutionary outcome depends in a complex way on ecological and genetic parameters. Expand
SPECIATION THROUGH COMPETITION: A CRITICAL REVIEW
TLDR
These theoretical models do not support the conclusion that sympatric speciation is a likely outcome of competition for resources, because in their parapatric model (Doebeli and Dieckmann 2003), clustering into distinct phenotypes is driven by edge effects, rather than by frequency‐dependent competition. Expand
Effects of genetic architecture on the evolution of assortative mating under frequency-dependent disruptive selection.
TLDR
It is shown that the range of parameters for which speciation is possible increases when mutational steps are large, and extensions of the original model, which add a second locus influencing the trait, increase the likelihood of competitive speciation. Expand
Adaptive dynamics as a mathematical tool for studying the ecology of speciation processes
TLDR
The issue of speciation appeared to be settled: according to the established dogma, biological diversification occurred in allopatry due to the accumulation of genetic differences in geographically isolated populations, but this view still prevails today, although perhaps less dominantly than before. 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
Spatial self-structuring accelerates adaptive speciation in sexual populations
TLDR
Spatial self-structuring facilitates the evolution of assortative mating and accelerates adaptive speciation, and it renders speciation less sensitive to costs of assortsative mating, especially for individuals that prefer rare phenotypes. Expand
Intraspecific Competitive Divergence and Convergence under Assortative Mating
TLDR
A multilocus model of a quantitative trait that is under frequency‐dependent selection caused by intraspecific competition and acts as mating character for assortment is investigated, identifying the conditions that lead to the establishment of reproductively isolated clusters. Expand

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
