Operational sex ratio (OSR) theory predicts that sexual differences in potential reproductive rates (PRRs) create biases in the OSR and thus determine the relative strength of sexual selection (competition and choice) operating on each sex. Although this theory is well accepted, empirical studies that quantify it are still lacking. This paper presents such a study. I measured the natural OSR of Galilee St. Peter’s fish (Sarotherodon galilaeus) in the field (Lake Kinneret) and examined the… Expand

For a few males more: do changes in sex ratio predict reproductive success and offspring survival?
TLDR
Although each female produced a single clutch regardless of sex ratio, higher proportions of males depressed the average number of clutches per male, indicating adult male competition and sexual conflict reduce the fitness of both males and females. Expand
The influence of operational sex ratio on the mating behaviour of reindeer (Rangifer tarandus L.) during an experimental rut: the effect of male age
TLDR
The results suggest that age is an important factor with respect to how male reindeer respond to differing OSR values, and future research aiming to expand the generalizability of experimental OSR theory to a wider range of taxa and ecological conditions need to consider other factors that will impact competition for mates, such as prime reproductive age. Expand
Mating distribution and its temporal dynamics affect operational sex ratio: a simulation study
TLDR
The OSR was influenced by the distribution of matings in time and among males when the male mating phase was limited by a parental phase and was shaped by the numbers of males and females and their capacities for collateral investment. Expand
Breeding system evolution in relation to adult sex ratios
TLDR
It is shown that in a wild polygamous plover population these ratios seem to be uncorrelated, and ASR was better than OSR at predicting the duration of female brood care in a polygamy plover where females have variable care and the contribution of these results to the understanding of breeding system evolution is discussed.

Sex Ratio and Mating Behavior in the Calanoid Copepod Pseudodiaptomus annandalei
TLDR
Although the sex ratio is supposed to induce a modification in mate guarding, no differences were found here, which is in agreement with theoretical models that predict a possible slackening of mate selection when encounters are mate limited. Expand
The Behavioral Ecology of Sex Tourism: The Consequences of Skewed Sex Ratios
TLDR
The author demonstrates that male-skewed sex ratios increase men’s sex tourism rationalization and intent, while women’'s predispositions are not sensitive to sex ratios. Expand
PARENTAL ROLES AND THE AMOUNT OF CARE IN A BI-PARENTAL SUBSTRATE BROODING CICHLID: THE EFFECT OF SIZE DIFFERENCES WITHIN PAIRS
TLDR
The amount of parental care is largely affected by the relative size within pairs independent of sex in J. ornatus, and observations of aggressive behaviours within pairs suggest that the larger fish are likely to make the partners perform parental care. Expand
The effect of male coloration on female mate choice in closely related Lake Victoria cichlids (Haplochromis nyererei complex)
TLDR
Male coloration in haplochromine cichlids does underlie sexual selection by direct mate choice, involving the capacity for individual assessment of potential mates by the female, and may explain rapid speciation by sexual selection on male coloration. Expand
The effect of environmental and social factors on the courtship and mating dynamics of the smooth newt, Triturus v. vulgaris
TLDR
There is variance in male mating success but the relative contributions of environmental factors and phenotypic traits needs further clarification. Expand
The financial consequences of too many men: sex ratio effects on saving, borrowing, and spending.
TLDR
Examination of how sex ratio influences saving, borrowing, and spending in the United States shows that male-biased sex ratios lead men to discount the future and desire immediate rewards. Expand

Potential Reproductive Rates and the Operation of Sexual Selection
TLDR
This framework for relating sex differences in mating competition to the operational sex ratio, potential reproductive rates, and parental expenditure differs from Triver's concept of the relation between parental investment and mating competition in three ways. 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

TLDR
A new model of mate choice is developed which shows that OSR theory can be used to integrate the effect of sex differences in both mating rate and variation in mate quality to predict the direction ofmate choice. Expand
The operational sex ratio influences choosiness in a pipefish
TLDR
In the pipefish (Syngnathus typhle), males switched from maximizing mate quality to minimizing the risk of not reproducing as the operational sex ratio, OSR, became male biased. Expand
Operational sex ratio, mediated by synchrony of female arrival, alters the variance of male mating success in Japanese medaka
TLDR
It is suggested that differences between males in their ability to scramble for females can generate important variance in mating success, a mechanism that is often overlooked in the literature on mating systems. 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
INDIVIDUAL SEX RATIO ADJUSTMENT IN RESPONSE TO THE OPERATIONAL SEX RATIO IN THE SOUTHERN GREEN STINKBUG
TLDR
It appears that the southern green stinkbug is capable of facultative sex ratio adjustment in response to the operational sex ratio, increasing the production of sons when males are rare. Expand
Mutual sexual selection in a monogamous seabird
TLDR
The results of a study of mate preferences of the crested auklet Aethla cristatella, a monogamous seabird in which both sexes are ornamented, confirm the idea that ornaments expressed in both sexes could be favoured by mutual mating preferences. Expand
Costs and Benefits of Female Mate Choice: Is There a Lek Paradox?
TLDR
It is argued that, although females are expected to pay lower costs in noneconomic mating systems, this need not translate into examining fewer males or spending less time in this activity, and there may be no lek paradox. Expand
Extraordinary Sex Roles in the Eurasian Dotterel: Female Mating Arenas, Female-Female Competition, and Female Mate Choice
  • T. Burke

  • The American Naturalist
  • 1994
TLDR
It seems that females are the more active sex in mate choice, as competition among females on the mating arenas of the dotterel resembles competition among males on leks, but the direction of mate choice does not appear to match the analogy of sex-role-reversed lekking. Expand
