Defining sex roles has been driven by differences in mating systems at the extreme: polygyny and polyandry. Roles may reverse depending on which sex limits the reproductive rate of the other, and it is generally the female that limits the male. Males therefore compete for female mates. But in species in which the male limits the reproductive rate of the female, the female competes for male mates and assumes the masculine role. Complications arise, however, in species with typical roles when… 

Social Reversal of Sex‐Biased Aggression and Dominance in a Biparental Cichlid Fish (Julidochromis marlieri)

It is suggested that relative mate size strongly influences the sex bias of aggression and dominance in J. marlieri and that this aspect of the social environment can override the influence of gonadal sex on an individual's behavior.

The “Sex Role” Concept: An Overview and Evaluation

The validity of the “sex role” concept in evolutionary biology is questioned and the term is recommended to be replaced with operational descriptions, so that confusing the two obscure science communication in society.

Behavioural and hormonal aspects of the breeding ecology in sex-role reversed polyandrous birds

It is suggested that males were unable to effectively guard their Christina Muck PhD Thesis 54 females to prevent extrapair paternity due to 1) the dense habitat they live in and 2) the onset of incubation before clutch completion.

Mate Choice, Sex Roles and Sexual Cognition in Vertebrates: Mate Choice Turns Cognition or Cognition Turns Mate Choice?

This review aims to elucidate various aspects associated with cognitive sex differences, the different roles of males and females in social and sexual interactions, and the potential influence of cognition on mate choice decisions to identify ways to answer the central question of how the triad of sex, cognition, and mate choice interacts.

Maintenance of genetic variation in sexual ornaments: a review of the mechanisms

It is discussed how the traditional ways of testing for genetic benefits can usefully be supplemented by tests detecting benefits resulting from specific mechanisms maintaining VA in sexual ornaments.

Sex Role Reversal and High Frequency of Social Polyandry in the Pheasant-Tailed Jacana (Hydrophasianus chirurgus)

It is highlighted that some aspects of polyandrous breeding might deviate from stereotyped view on sex-role reversal, and the importance of further within species and comparative studies in order to fully understand the mechanisms leading to sex- role reversal.

Anisogamy, chance and the evolution of sex roles.

Reproductive behaviors and sex roles during a diurnal cycle of the goby, Lythrypnus pulchellus (Teleostei: Gobiidae)

The gorgeous goby shows plasticity in their reproductive behaviors in response to OSR, and the elucidation of the plasticity of mating behaviors is relevant to understand the interactions in sequential hermaphrodite fishes as L. pulchellus.

Unifying and Testing Models of Sexual Selection

This work reviews evolutionary explanations for the relationship between anisogamy, potential reproductive rates, parental care, sex roles, and mate choice, and considers other forms of selection that can make females mate nonrandomly.

It is conceptualized that there are five ways in which a sexually dimorphic trait, apart from the primary sex traits, can be fixed: sexual selection, fecundity selection, parental role division, differential niche occupation between the sexes, and interference competition.



Unusually dynamic sex roles in a fish

This is the first time that a shift in sex roles has been shown in a vertebrate, and it might be explained by a large decline in male abundance, strongly skewing the sex ratio towards females.

Sexual selection and the potential reproductive rates of males and females

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.

Competing Females and Caring Males. Polyandry and Sex-Role Reversal in African Black Coucals, Centropus grillii

It is concluded that the black coucal currently represents the only altricial bird species with sole male parental care and a classical polyandrous mating system.

Sex-Role Reversal in the Black-Chinned Tilapia, Sarotherodon Melanotheron (RÜPpel) (Cichlidae)

The prediction of sex role reversal (competitive females and discriminating males) is confirmed by examining competition for mates and mate choice in the black-chinned tilapia, Sarotherodon melanotheron, a paternal mouth brooding cichlid.

Male mate choice and female-female competition for mates in the pipefish Nerophis ophidion

Sex-role reversal in the tidewater goby, Eucyclogobius newberryi

The reproductive behavior of the tidewater goby is investigated, finding that its sexual behavior is apparently unique among fishes because it is the only reported case of sex-role reversal in teleost males that do not bear eggs or developing young.

Pipefishes and seahorses: Are they all sex role reversed?

Monogamy and sex role reversal in the pipefish Corythoichthys haematopterus

It is suggested that mate guarding by females is a primary proximate factor for maintenance of monogamy in this fish and provides the first example of sex role reversal among monogamous syngnathid fish.


Both the timing of female-initiated sex events and the high proportion of male initiations to which females responded suggested that copulations in monogamous pairs were also determined more by male preferences.
