Extravagant secondary sexual characters, i.e. sexual ornaments, are exaggerated, often bilaterally symmetrical traits of great intricacy of design. The full expression of such traits is likely to be very costly and close to the limits of production. Any kind of environmental stress is therefore more likely to affect the expression of ornaments than that of any other morphological trait not subjected to strong directional selection. One measure of the ability of individuals to produce… Expand

Figures from this paper

Patterns of fluctuating asymmetry in sexual ornaments predict female choice
TLDR
It is demonstrated that female choice can be directly predicted from the relationship between the degree of fluctuating asymmetry and the size of a secondary sexual character, suggesting that females prefer exaggerated secondary sexual characters if they reliably demonstrate the ability of males to cope with genetic and environmental stress. Expand
Fluctuating asymmetry in the redcollared widow : testing theories of sexual selection.
TLDR
It is argued that the assumptions of the Moller's fluctuating asymmetry hypothesis are too simplistic for it to hold true for all species without taking the basic biology of the species into account. Expand
Phenotypic variation and fluctuating asymmetry in sexually dimorphic feather ornaments in relation to sex and mating system
TLDR
CV and FA were not related, suggesting that phenotypic plasticity and developmental instability are independent components of phenotypesic variation. Expand
Female swallow preference for symmetrical male sexual ornaments
TLDR
Male swallows with elongated, symmetric tails mated earlier, and enjoyed larger annual reproductive success than did males with shortened tails and increased asymmetry, which suggests that females in their mate choice use ornament asymmetry and size as reliable indicators of male quality. Expand
Developmental stability, sexual selection and speciation
TLDR
The low degree of developmental stability and the large amount of genetic variance in secondary sexual characters in small, marginal populations could set the scene for rapid development of divergence and speciation in marginal populations. Expand
Components of phenotypic variation in avian ornamental and non-ornamental feathers
TLDR
It was found that only dispersion of observations around the regression line contributed significantly to total variation, consistent with ornamental feather traits being subject to directional selection due to female mate preferences, where large body size is less important than in male–male competition. Expand
Patterns of asymmetry in body traits and genitalia in two distant populations of a Neotropical scorpion
TLDR
The aims of this work are to analyze asymmetry patterns of genitalic and somatic traits in the scorpion Bothriurus bonariensis (Bothriuridae) and to compare these values between central and peripheral populations of its distribution, and to observe that types of asymmetry in genitalic traits differed in both populations. Expand
Testosterone stress does not increase asymmetry of a hormonally mediated sexual ornament in a lizard
TLDR
Results suggest that the development of coloration on both sides of the throat midline follows a random pattern, suggesting that asymmetry is not affected by physiological stress and that this trait is not a sexually selected signal in P. algirus males. Expand
Patterns of Fluctuating Asymmetry in Sexual Ornaments of Birds from Marginal and Central Populations
TLDR
The high developmental instability of secondary sex traits in marginal populations could be due to extreme genetic and environmental stress, and stressful environments may also increase the genetic variance. Expand
Inter- and intra-sexual patterns of fluctuating asymmetry in the red-billed streamertail: should symmetry always increase with ornament size?
TLDR
The results do not support any of the predictions made by fluctuating asymmetry hypotheses and suggest that stabilising selection may act on ornaments as well as non-ornaments. Expand

TLDR
I used fluctuating asymmetry in ornament size as a measure of the ability of individuals to achieve identical development of the ornament on both sides of their body, suggesting that asymmetry per se and inherent differences between individuals affected their flight performance. Expand

TLDR
The possibility that the evolution of mating preferences and secondary sex traits can be based on heritable differences in viability is examined with a three‐locus model, based on a monogamous mating system that precludes such a Fisherian mating advantage being required. Expand
Fluctuating asymmetry in male sexual ornaments may reliably reveal male quality

The antler cycle in Newfoundland caribou and the evolution of horn-like organs in females of the genus Rangifer is studied to help clarify the role of antlers in the lives of reindeer and Caribou. Expand
Truth in Advertising: The Kinds of Traits Favored by Sexual Selection
TLDR
The truth in advertising model describes a mechanism of sexual selection to account for the evolution of the kinds of traits used by males of polygynous species to compete for and attract mates and deemphasizes the traditional dichotomies between the effects ofsexual selection and natural selection. Expand
Female choice selects for male sexual tail ornaments in the monogamous swallow
TLDR
In the monogamous swallow, Hirundo rustica, males with experimentally elpngated tail ornaments obtain mates more quickly than males with shorter tails, and enjoy increased reproductive output in one breeding season, suggesting male sexual ornament may also be maintained by female mate choice in monogamous species. Expand
Sexual selection, natural selection and quality advertisement
TLDR
Both mating advantage and mortality disadvantage increase with ornament size, and balance at its optimal development, and if a given adornment reduces survival most in low quality phenotypes, the optimum increases with phenotypic quality. Expand

TLDR
The models elucidate genetic mechanisms that can initiate or contribute to rapid speciation by sexual isolation and divergence of secondary sexual characters in polygamous species. Expand

TLDR
It is reported here that males in which the tail was experimentally elongated showed higher mating success than males having normal or reduced tails: males with shortened tails held their territories as long as did other males. Expand
