Theory suggests that the net benefit of allocating resources to a sexual trait depends both on the strength of sexual selection on that trait and on individual condition. This predicts a tight coevolution between sexual dimorphism and condition dependence and suggests that these patterns of within‐sex and between‐sex variation may share a common genetic and developmental basis. Although condition‐dependent expression of sexual traits is widely documented, the extent of covariation between…

Experimental evidence of condition‐dependent sexual dimorphism in the weakly dimorphic antler fly Protopiophila litigata (Diptera: Piophilidae)
TLDR
A shared developmental basis to condition dependence and sexual dimorphism can arise via sexual selection on males even in lineages lacking highly exaggerated male traits, as previously reported for highly dimorphic species.
Evolution of sexual dimorphism in phenotypic covariance structure in Phymata
  • D. Punzalan, L. Rowe
  • Biology, Psychology
    Evolution; international journal of organic evolution
  • 2015
TLDR
It is found that sexual dimorphism in both mean and covariance structure was pervasive but also that the multivariate distance between sex‐specific means was correlated with sex differences in the leading eigenvector of P, while accounting for uncertainty in phylogenetic relationships.
Interactive effects of competition and social environment on the expression of sexual dimorphism
TLDR
It is demonstrated that ecologically and socially mediated interactions between sex‐specific resource acquisition and allocation can contribute to variation in the expression of sexual dimorphism.
Parasitism and the expression of sexual dimorphism
TLDR
It is shown that males have higher trematode parasite loads for their body size than females and that a key sexually selected trait covaries negatively with parasite load in males and found evidence of a weaker negative relationship between the analogous female trait and parasite infection.
Context-dependent expression of sexual dimorphism in island populations of the common wall lizard (Podarcis muralis)
TLDR
The results support the hypothesis of a context-dependent sexual dimorphism in common wall lizards inhabiting the Tuscan Archipelago, and indicate that environmental features of islands play an additive effect to ontogenetic, biogeographic and genetic factors in defining variation in head shape sexualDimorphism.
Condition dependence and the maintenance of genetic variance in a sexually dimorphic black scavenger fly
TLDR
Quantitative genetic evidence in support of the genic capture model was inconsistent and weak at best, and genetic variance in fore femur width was low to nil, perhaps depleted by putatively strong sexual selection.
Sexual size dimorphism and the integration of phenotypically plastic traits
TLDR
Investigation of phenotypic plasticity associated with predation and seasonal time constraints in development as a source of SSD in the Azure damselfly, Coenagrion puella reveals plasticity in SSD is mediated by environmental variation and environment‐dependent, sex‐specific changes in the association of body size with growth rate and fat storage mediated changes inThe offset of SSD.
Sexual size dimorphism and the integration of phenotypically plastic traits
TLDR
This work investigated phenotypic plasticity associated with predation and seasonal time constraints in development as a source of SSD in the Azure damselfly, Coenagrion puella and revealed that plasticity in SSD is mediated by environmental variation.
On the evolution of heightened condition dependence of male sexual displays
TLDR
Testing how a suite of cuticular hydrocarbons used in sexual displays are affected by adult diet and the potential for any condition‐dependent response to evolve in a laboratory‐adapted population of the Australian fruit fly Drosophila serrata suggests that there is limited opportunity for males to evolve further condition dependence in response to yeast availability.
Variation in sexual size dimorphism among populations: testing the differential‐plasticity hypothesis
TLDR
It was found that females were larger than males at all temperatures and the degree of this dimorphism was largest at the highest temperature (31 °C) and smallest at the lowest temperature (22‰°C).

SEXUAL SELECTION, GENETIC ARCHITECTURE, AND THE CONDITION DEPENDENCE OF BODY SHAPE IN THE SEXUALLY DIMORPHIC FLY PROCHYLIZA XANTHOSTOMA (PIOPHILIDAE)
TLDR
It is argued that condition dependence may weaken intersexual genetic correlations and facilitate the evolution of sexual dimorphism, and the role of sexual selection in the Evolution of condition dependence is supported, but considerable variation in condition dependence among sexual traits is revealed.

  • 2000
TLDR
It is shown that a Mendelian genetic model including elementary details of sexual differentiation provides novel insight into the evolution of sex differences via sex limitation, and that selection interacts with genetic variation for sexual dimorphism to produce unanticipated patterns of trait divergence or convergence between the sexes.
SIGNAL TRAIT SEXUAL DIMORPHISM AND MUTUAL SEXUAL SELECTION IN DROSOPHILA SERRATA
TLDR
The evolution of sexual dimorphism in D. serrata appears to have been achieved by sex-limited expression of traits controlled by genes on the X chromosome and is likely to be in its final stages.
EVOLUTION OF CONDITION‐DEPENDENT SEX ORNAMENTS AND MATING PREFERENCES: SEXUAL SELECTION BASED ON VIABILITY DIFFERENCES
  • M. Andersson
  • Biology
    Evolution; international journal of organic evolution
  • 1986
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.
INTRALOCUS SEXUAL CONFLICT AND THE GENETIC ARCHITECTURE OF SEXUALLY DIMORPHIC TRAITS IN PROCHYLIZA XANTHOSTOMA (DIPTERA: PIOPHILIDAE)
TLDR
The genetic architecture of sexual and nonsexual morphological traits in Prochyliza xanthostoma is investigated and theory suggests that intralocus sexual conflict can be resolved substantially by genomic adaptation, but further work is required to identify the proximate mechanisms underlying these patterns.
Convergent evolution of sexual shape dimorphism in Diptera
TLDR
Comparisons of phenotypic variation in body shape in true flies suggest that a shared pattern of covariation among traits may have channeled the evolution of sexually dimorphic body elongation in these species, and static allometries may have been shaped by species‐specific selection pressures or genetic architectures.
Environmental variation shapes sexual dimorphism in red deer.
TLDR
It is shown that divergent growth of male and female red deer after 32 years of winter warming and 15 years of contemporaneously earlier plant phenology support this prediction that males grew more rapidly and increased in size, while female size declined in response to warmer climate.
SEX CHROMOSOMES AND THE EVOLUTION OF SEXUAL DIMORPHISM
  • W. Rice
  • Biology

  • 1984
TLDR
The idea that sex chromosomes also play an important role in the evolution of sexually dimorphic traits is evaluated and how the sex chromosomes can facilitate this evolution is suggested.
Condition-dependent signalling of genetic variation in stalk-eyed flies
TLDR
It is shown that genetic variation underlies the response to environmental stress of a sexual ornament (male eye span) in the stalk-eyed fly Cyrtodiopsis dalmanni, and this results strongly support the hypothesis that female mate choice yields genetic benefits for offspring.
CONDITION DEPENDENCE OF SEXUAL ORNAMENT SIZE AND VARIATION IN THE STALK‐EYED FLY CYRTODIOPSIS DALMANNI (DIPTERA: DIOPSIDAE)
TLDR
Evaluation of male eyespan allows females to gain additional information about male condition over and above that given by body size, and accord well with condition‐dependent handicap models of sexual selection.
