Sexual Selection: Is Anything Left?
This paper reviews a sequence of definitions of what counts as sexual selection that reflect increasing knowledge of the diverse ways animals participate in reproductive social behavior and recommends the approach of social selection, which focusses on how to increase the size of the pie rather than how to monopolize a larger share of a fixed pie.
Prudent males, group adaptation, and the tragedy of the commons
The eco-evolutionary dynamics of a curious system where an asexual all-female fish species requires sperm from other species as a developmental trigger, without utilizing the genes from sperm are analyzed.
The Origin of Beauty : Contrasting the Handicap Hypothesis and Design Theory
It is hypothesized that there is an underlying genetic mechanism designed to maintain traits that are “beautiful” but appear to handicap the species, and the variability of female trait preferences hints at a complex genetic linkage.
Rethinking Bateman’s Principles: Challenging Persistent Myths of Sexually Reluctant Females and Promiscuous Males
Angus Bateman’s conclusions and predictions have become axiomatic and, at times, have gone unquestioned even when modern empirical data do not conform to this model, and the origins and history of these ideas are reviewed.
Homosexual Pairing within a Swarm-Based Mating System: The Case of the Chironomid Midge
It is shown that homosexual pairing here, exclusively involving male/male pairs, is common, and it is attempted to show that this observation, together with data on insect predators of swarming midges, can be used to penetrate the mysteries of this fascinating but elusive mating system.

Sexual selection in females
Intrasexual competition in females: evidence for sexual selection?

Understanding sex differences in sexual selection will require further exploration of the extent of mutual intrasexual competition and the incorporation of quality of mating success into the study of sexual selection in both sexes.


Defining sexual selection as sex-dependent selection
Intra-sexual selection in Drosophila
Epigamic selection includes the major part of what Darwin meant by sexual selection, and is introduced to apply to characters which increased the fertility of a given mating and therefore had a selective value for the species as a whole.
Bateman's results are unreliable, his conclusions are questionable, and his observed variances are similar to those expected under random mating, according to a reanalysis of his study of Drosophila melanogaster.
Forces and Strategies in Evolution. (Book Reviews: Sexual Selection and the Descent of Man, 1871-1971)
This volume significantly broadens the scope of modern evolutionary biology by looking at this important and long neglected concept of great importance, sexual selection, and considers many aspects of sexual selection in many species, including man, within the context of contemporary evolutionary theory and research.
Parental investment, sexual selection and sex ratios
An integrative model shows how factors interact to generate sex roles and underscores the need to distinguish between the ASR and the operational sex ratio (OSR) if mortality is higher when caring than competing this diminishes the likelihood of sex role divergence.
Testing the genetics underlying the co-evolution of mate choice and ornament in the wild
Insight is provided into the field of sexual selection by showing that genes coding for mate choice for an ornament probably evolve by their own pathways instead of ‘hitchhiking’ with genes coded for the ornament.
The Problem with Paradigms: Bateman's Worldview as a Case Study1
This introduction to the symposium concludes by emphasizing the heuristic value of Bateman's contributions, as well as the problems that arise whenBateman's paradigm is viewed through the lens of modern behavioral ecology and evolutionary theory.
Direct versus indirect sexual selection: genetic basis of colour, size and recruitment in a wild bird
It is shown that variation in coloration is only weakly heritable, and that two components of offspring fitness—nestling size and fledgling recruitment—are strongly dependent on parental effects, rather than genetic effects.
Sexual conflict over mating and fertilization: an overview
  • G. Parker

The weight of current evidence supports sexual conflict for many cases and the special features of postcopulatory sexual conflict are reviewed, as well as some general features of importance for conflict resolution.
Ornament evolution in dragon lizards: multiple gains and widespread losses reveal a complex history of evolutionary change
This work examined the pattern of ornament gains and losses in 240 species of dragon lizards in order to elucidate the relative contribution of these two factors in the evolution of mutual ornamentation and found that the evolutionary loss of some ornaments is concentrated more in males than females.
