Sex-role reversal occurs when females compete more intensely than males for access to mates. In this paper, we survey the occurrence of sex-role reversal in vertebrates: we focus on behavioural aspects of sex-role reversal and we examine possible endocrinological correlates of this phenomenon. The best documented cases among vertebrates of sex-role reversal occur in fish and birds. In nearly all sex-role reversed species or populations, females have higher potential reproductive rates than… Expand
Neuroendocrinology of sex-role reversal.
TLDR
It is refuted that the most widely tested activational hypothesis for sex differences in androgen secretion is correct; sex-role reversed females do not have higher levels of androgens in circulation than males, however, there is some evidence that the effects of androgen may be sex-specific.

The Role of Androgens in Male Pregnancy and Female Competitive Behavior in a Sex Role Reversed Pipefish
TLDR
The goal of this dissertation was to examine the role of androgens in the male reproductive cycle and female intrasexual competitive behavior in the sex-role reversed Gulf pipefish, Syngnathus scovelli and develop a model for the hormonal regulation of themale reproductive cycle in seahorses.

Ecological determinants of sex roles and female sexual selection
TLDR
Research on the flower-feeding bushcricket Kawanaphila nartee has underscored the importance of ecology to reproduction by showing that food availability can affect the operational sex ratio and thus sex roles, indicating that sex roles are not necessarily fixed but rather respond plastically to environmental factors.

Competing females and caring males. Sex steroids in African black coucals, Centropus grillii
TLDR
It is concluded that the absence of one testis does not provide a mechanism for sex role reversal in black coucals, suggesting androgens are not involved in the regulation of male-like traits in females or females are sensitive to relatively low levels of these steroids. Expand
Testosterone secretion varies in a sex- and stage-specific manner: insights on the regulation of competitive traits from a sex-role reversed species
TLDR
The findings suggest that levels of T in circulation alone do not predict variation in competitive traits across levels of analysis, including gonadal sex and parental role, and that selection for female mating competition and male care may generate different physiological regulation of competitive traits in jacanas.

Sex Ratio Bias Leads to the Evolution of Sex Role Reversal in Honey Locust Beetles
TLDR
This study investigated mating system evolution in a sex-role-reversed beetle using experimental evolution under manipulated sex ratios and food regimes, and found that in female-biased populations, females evolved to be more attractive and the sex roles became more reversed. Expand
Progesterone modulates aggression in sex-role reversed female African black coucals
TLDR
It is shown that territorial aggression in female black coucals is modulated by progesterone, suggesting that progester one may suppress territorial aggression and is downregulated during aggressive encounters. Expand
Hormones and the development of sex differences in behavior
TLDR
Results of experimental manipulations of sex steroid actions in juvenile zebra finches suggest hormonal regulation of the onset of interest in the opposite sex as sexual maturity is reached, and the concepts of organization and activation raise a number of questions. Expand
The Effects of Synthetic Estrogen Exposure on the Sexually Dimorphic Liver Transcriptome of the Sex-Role-Reversed Gulf Pipefish
TLDR
The results suggest that the ancestral state of estrogen-regulated female reproductive physiology has been retained in all sex-role-reversed vertebrates thus far studied, despite substantial evolution of the hormonal regulation of ornamentation and mating behavior in these interesting taxa. Expand

Prospects for Sex Role Reversal in Teleost Fishes
TLDR
This reproductive rates approach should reveal more examples of sex role reversal in teleosts and could contribute to the development of hitherto largely unformulated generalisations about sex differences inteleost fishes. Expand
Sex Roles Are Not Always Reversed When the Potential Reproductive Rate Is Higher in Females
  • N. Okuda
  • Biology, Medicine
  • The American Naturalist
  • 1999
TLDR
The facts that the variance in reproductive success was greater in males and the males developed a sexual trait suggest that sexual selection is acting more strongly on males than on females, suggesting that this fish is not sex‐role reversed. Expand
The Bateman gradient and the cause of sexual selection in a sex–role–reversed pipefish
TLDR
It is shown that, in the male–pregnant pipefish Syngnathus typhle, females exhibit a stronger positive association between number of mates and fertility than do males and that this relationship responds in the predicted fashion to changes in the adult sex ratio. Expand
Operational Sex Ratios in Seahorses
TLDR
A study of a laboratory population of the Sri Lankan seahorse Hippocampus fuscus finds that the operational sex ratio (OSR) among mated seahorses is male-biased, because unmated (empty) males can prepare to mate more quickly and can remain ready to mate for longer than can unmated females. Expand
Sex-Role Reversal in the Black-Chinned Tilapia, Sarotherodon Melanotheron (RÜPpel) (Cichlidae)
In the animal kingdom most species follow standard sex roles: males compete more intensely for mates and females exert greater mate choice. Recent theory suggests that the direction of sexualExpand
Shield Characteristics Are Testosterone-Dependent in Both Male and Female Moorhens
TLDR
In the moorhen, moorhens implanted with testosterone had higher intensities of ectoparasite infestations than control birds, but other indirect measures of immunocompetence did not differ significantly between the two categories of birds. Expand
Seahorses exhibit conventional sex roles in mating competition, despite male pregnancy
TLDR
The laboratory experiments in this paper demonstrate that, contrary to expectations, seahorses exhibit conventional sex roles: male seahorse compete more intensely than females for access to mates, on both the first and final days of courtship. Expand
Sexual selection and the potential reproductive rates of males and females
TLDR
It is shown that among species where males care for the young, the sex with the higher potential reproductive rate competes more intensely for mates than thesex with the lower potential rate of reproduction. Expand
Plasma steroid hormones in relation to behavioral sex role reversal in the spotted sandpiper, Actitis macularia.
TLDR
The results indicate that the high level of intrasexual competition for mates among female spotted sandpipers is not based upon a total reversal of the normal male/female levels of androgens and estradiol. Expand
Courting females: ecological constraints affect sex roles in a natural population of the blenniid fish Salaria pavo
TLDR
Evidence for ecological modulation of sex roles in a natural population of the blenniid fish Salaria pavo (Risso) is presented, where nest sites are very scarce, courtship is almost entirely initiated by females, and both male and female intra-sexual competition occurs. Expand
