Rapid divergence and speciation can occur between populations with or without ecological differences under selection for success in intraspecific social competition-competition in which an individual must win in contests or comparisons with conspecific rivals in order to gain access to some resource, including (under sexual selection) mates. Sexual selection theory is extended to encompass social competition for resources other than mates. Characters used in social competition can undergo… 
The role of male contest competition over mates in speciation
TLDR
It is argued that sexual selection through male contest competition can affect speciation in ways other than mate choice and the role ofmale contest competition in speciation remains largely scientifically unexplored.
Pervasive reinforcement and the role of sexual selection in biological speciation.
TLDR
It is shown that in birds, divergence in song and plumage in allopatry corresponds poorly with whether species mate assortatively in hybrid zones and argued that many other factors besides trait divergence affect propensity to hybridize, including rarity of conspecific mates and choice based on territory rather than male traits.
Role of sexual selection in speciation in Drosophila
TLDR
Comparative studies based on intra- and inter-sexual selection provide evidence that both mate choice and male–male competition can cause selection of trait and preference which thereby leads to divergence among species.
The evolution of female ornaments and weaponry: social selection, sexual selection and ecological competition
TLDR
It is shown that selection often falls outside the limits of traditional sexual selection theory, particularly in females, and it is concluded that the evolution of these traits in both sexes is best understood within the unifying framework of social selection.
Evolution of choosiness dictates whether search costs of mate choice enhance speciation by sexual selection
TLDR
A diploid population genetic model of how female search costs and evolution of female 'choosiness' interact to drive speciation in allopatry and secondary contact found that speciation could be maintained under a wide range of conditions with arbitrary male traits, but not with magic male traits.
The counterintuitive role of sexual selection in species maintenance and speciation
TLDR
It is shown that when sexually selected traits are under ecologically divergent selection, the situation most favorable to speciation, mating preferences tend to introgress faster than trait alleles, causing sexual selection to counter the effects of local adaptation, and the net amount of trait divergence often drops with stronger Fisherian sexual selection.
SYMPATRIC SPECIATION BY SEXUAL SELECTION ALONE IS UNLIKELY
TLDR
Hypergeometric phenotypic and individual-based genotypic models are used to explore sympatric speciation by sexual selection under a broad range of conditions and suggest similarity-based female preferences that do not cause sexual selection are less destabilizing to the maintenance of genetic variability and may result in sympatrics speciation across a broader range of initial conditions.
Evolution of Phenotypic Sex Differences in Cooperative Species: is Competition an Opposing Force?

TLDR
Results indicate that although extrapair matings and environment attributes are determinant to the evolution of sex differences, males and females of cooperative species seem to be more alike than their non-cooperative counterparts.
Host shifts and signal divergence: mating signals covary with host use in a complex of specialized plant‐feeding insects
TLDR
The hypothesis that hosts shifts have led to speciation in the Enchenopa binotata species complex of treehoppers in part through their influence on divergence in mate communication systems is supported.
Contrasting impacts of competition on ecological and social trait evolution in songbirds
TLDR
It is found that interspecific competition strongly influences the evolution of traits involved in resource use, with a weaker effect on plumage signals, and very little effect on song.

TLDR
Mechanisms for clinal speciation first outlined in genetic terms by Fisher (1930) are reinvestigated and the latter mechanism is potentially much more powerful for initiating sexual isolation and character divergence along a cline than is selection against hybridization.
Rapid speciation and chromosomal evolution in mammals.
TLDR
Speciation and chromosomal evolution seem fastest in those genera with species organized into clans or harems or with limited adult vagility and juvenile dispersal, patchy distribution, and strong individual territoriality, consistent with the above hypothesis regarding the evolutionary importance of demes.

TLDR
The data presented here for Anolis garmani tend to support the view that those males who do most of the mating are those who have tended to demonstrate the superiority of their non sexlinked genes.
Social organization and mating success in local song populations of village indigobirds, Vidua chalybeata.
TLDR
Song behavior best explained differences in mating success of males, with lesser effects of neighboring males and the defensible resources around the call-sites, in two populations at Lochinvar National Park, Zambia.
Courtship Behavior and Reproductive Isolation between Western Grebe Color Morphs
TLDR
In playback experiments, courting males of the two color phases readily distinguished the two call-types and only approached or answered female calls of their own phase, which suggests that the high degree of segregation in sympatry possibly results from a learning process, whereby individuals rapidly sharpen their discriminative abilities.
Reliability in communication systems and the evolution of altruism
The evolution of a communication system depends on the existence of individuals which gain from it, that is the senders of the signals and their receivers. These two share a common interest about
The Tungara Frog: A Study in Sexual Selection and Communication
TLDR
Though certain vocalizations allow males to obtain mates and thus should be favored by sexual selection, this study highlights two important costs of such sexual displays: the frogs expand considerable energy in their mating calls, and they advertise their whereabouts to predators.
Species Recognition, Dewlap Function and Faunal Size
TLDR
It is argued that species recognition in anoline lizards is not based on a single sign stimulus or releaser but on a complex of stimuli, separately and in various combinations identify the display animal.
