MANY species exhibit colour polymorphisms associated with alternative male reproductive strategies, including territorial males and 'sneaker males' that behave and look like females1–3. [...] Key Result Using parameter estimates from field data, the model predicted oscillations in morph frequency, and the frequencies of the three male morphs were found to oscillate over a six-year period in the field.Expand
A genetic approach to the rock-paper-scissors game.
TLDR
It is shown that this genotypic description of the dynamics results in the same equilibrium phenotype frequencies as the phenotypic models, but affects the stability of the system, changing the parameter region where coexistence of the three morphs is possible in a rock-paper-scissors game. Expand
Runaway social games, genetic cycles driven by alternative male and female strategies, and the origin of morphs
TLDR
The dynamics of male and female morphs with one- and two-locus genetic models were modeled and runaway ESS games are discussed in the context of self-reinforcing genetic correlations that build and promote the formation of morphotypic variation. Expand
Runaway social games, genetic cycles driven by alternative male and female strategies, and the origin of morphs
TLDR
The dynamics of male and female morphs with one- and two-locus genetic models were modeled and runaway ESS games are discussed in the context of self-reinforcing genetic correlations that build and promote the formation of morphotypic variation. Expand
Frequency-dependent reproductive success in female common lizards: a real-life hawk–dove–bully game?
TLDR
Results prove that female reproduction is sensitive to the social environment, and are consistent with a scenario of a hawk–dove–bully game, in which yellow females are aggressive hawks, orange females non-aggressive doves, and mixed females have a context-dependent bully strategy. Expand
Morph-specific assortative mating in common wall lizard females
TLDR
Results showed that crowding experienced by females did not affect mate choice, arguing against a flexible choice strategy by females, and sexual selection could contribute to the maintenance of color polymorphism in this species by a mix of assortative and non-assortative mating strategies. Expand
Permanent female mimics in a lekking shorebird
TLDR
A rare female-like morph of ruffs is described: the ‘missing’ third alternative mating strategy, which is called ‘faeder’ and appears to combine feminine and masculine behaviours. Expand
Selection on space use in a polymorphic lizard
TLDR
D divergence of male reproductive strategies in C. pictus does not seem to be related to differences in space use, and selection on space use in a natural population was not disruptive in either of the two years studied. Expand
Frequency-Dependent Selection on Female Morphs Driven by Premating Interactions with Males
TLDR
It is concluded that considering interactions among all players—here, males and females—is crucial to fully understanding the mechanisms underlying the maintenance of genetic polymorphisms in the wild. Expand

TLDR
A new model for the evolution of AMTs is suggested that incorporates both environmental and genetic effects, and is suggested to be a source, and possibly also a consequence, of sexual conflict. Expand
Competition and cuckoldry: estimating fitness of alternative reproductive tactics in plainfin midshipman
TLDR
The results provide the first exploration of the evolution of male ARTs in plainfin midshipman and, given the tractability of midship man system, a valuable next step will be to look for gene-by-environment interactions on tactic development and expression. Expand

Equal mating success among male reproductive strategies in a marine isopod
TLDR
It is reported that average reproductive success is equivalent among the three male morphs in monthly population samples collected over two years, indicating the absence of differential natural selection among morphs. Expand
Evolution of Alternative Reproductive Strategies: Frequency-Dependent Sexual Selection in Male Bluegill Sunfish
TLDR
Empirical evidence in a wild population of the bluegill sunfish shows that cuckolder will fertilize decreasing proportions of eggs, relative to parental males, as cuckolders increase in frequency in the population, which supports evolutionary models that assume negative frequency-dependent selection between the competing strategies.

A Genetic Polymorphism in the Swordtail Xiphophorus nigrensis: Testing the Prediction of Equal Fitnesses
TLDR
The data support the hypothesis that morph fitnesses are equal, the model is fairly robust to changes in population growth rate and differential death rates of morphs, and the confidence intervals are large, which suggests that the null hypothesis only be accepted with caution. Expand

TLDR
A review of endocrine data from six different species with male dimorphism shows consistent differences between morphotypes and a striking pattern: 11-ketotestosterone levels are uniformly elevated in each "courting male" morphotype relative to its "noncourting" conspecific. Expand

Allometric Engineering: A Causal Analysis of Natural Selection on Offspring Size
TLDR
The results experimentally validate premises underlying theories of optimal egg size: fecundity selection favoring the production of large clutches of small eggs was balanced by survival selection favoring large offspring, but large hatchlings did not always have the highest survival, contrary to most theoretical expectations.

TLDR
Results indicate that facial coloration is under activational influence of T, which is probably organized at sexual maturation, thus manifesting the more vivid expression in males. Expand
