The ratio of males to females in a species is often considered to be relatively constant, at least over ecological time. Hamilton noted that the spread of "selfish" sex ratio-distorting elements could be rapid and produce a switch to highly biased population sex ratios. Selection against a highly skewed sex ratio should promote the spread of mutations that suppress the sex ratio distortion. We show that in the butterfly Hypolimnas bolina the suppression of sex biases occurs extremely fast, with… Expand

    Rapidly Shifting Sex Ratio across a Species Range
    TLDR
    It is concluded that asynchronous invasion and decline of sex-ratio distorters combines with the evolution of host suppressors to produce a rapidly changing mosaic of sex ratio, likely to be fundamentally altered over short time scales. Expand
    Persistence of a Wolbachia-driven sex ratio bias in an island population of Eurema butterflies
    TLDR
    It is found that wFem appeared to be stably maintained for at least 12 years at a high frequency, resulting in the existence of an abnormally high number of virgin females, which is an attractive model for future studies on the population dynamics of sex ratios and mating behavior. Expand
    The Evolution of Sex Ratio Distorter Suppression Affects a 25 cM Genomic Region in the Butterfly Hypolimnas bolina
    TLDR
    The observations of the impact of suppression of sex ratio distorting activity reveal a very wide genomic imprint, reflecting its status as one of the strongest selective forces in nature. Expand
    Extraordinarily wide genomic impact of a selective sweep associated with the evolution of sex ratio distorter suppression
    TLDR
    The observations of the impact of suppression of sex ratio distorting activity reveal an extraordinarily wide genomic imprint, reflecting its status as one of the strongest selective forces in nature. Expand
    LOCAL SELECTION UNDERLIES THE GEOGRAPHIC DISTRIBUTION OF SEX‐RATIO DRIVE IN DROSOPHILA NEOTESTACEA

    TLDR
    It is shown that the prevalence of SR drive in Drosophila neotestacea varies between 0% and 30% among populations, and is common in the south whereas rare in the north, indicating that ecological selection on SR drive varies among populations. Expand
    Incomplete offspring sex bias in Australian populations of the butterfly Eurema hecabe
    TLDR
    Key features of the findings clearly depart from the Japanese feminization paradigm and highlight the potential for more subtle degrees of sex distortion in arthropods. Expand
    The Effective Size of Populations Infected With Cytoplasmic Sex-Ratio Distorters
    TLDR
    Analytical expressions for the coalescent effective size Ne of populations that are infected with SRDs are derived and these yield the effective size of populations infected with mutualistic endosymbionts or maternally inherited bacteria that induce cytoplasmic incompatibility, although in these cases, the reduction in Ne is expected to be less severe.

    Male-killing in African butterflies
    TLDR
    There are a number of unanswered questions to be targeted by future research work on the male-killing in African nymphalid butterflies, with special focus on the cases of Danaus chrysippus, Acraea encedon and Acraaea encedana. Expand
    Frequency‐dependent selection acting on the widely fluctuating sex ratio of the aphid Prociphilus oriens
    TLDR
    It is concluded that despite consistent operation of frequency‐dependent selection, the sex ratio continues to fluctuate because environmental conditions always push it away from equilibrium. Expand
    Suppression of Wolbachia-mediated male-killing in the butterfly Hypolimnas bolina involves a single genomic region
    TLDR
    It is concluded that a single genomic region of the H. bolina genome is necessary for male-killing suppression, and the findings favour hypotheses in which either multiple mutations are required within asingle genomic region, or the suppressor mutation is a singularly rare event. Expand

    TLDR
    Persistence of the population despite the very high frequency of the sex-ratio distorter appears to be associated with the ability of males to mate >50 times in their life combined with a high intrinsic rate of increase of the species. Expand
    Male-Killing Bacteria Trigger a Cycle of Increasing Male Fatigue and Female Promiscuity
    TLDR
    It is shown that increased female mating frequency can be explained as a facultative response to the depleted male mating resources in female biased populations. Expand
    Evolution of Male-Killer Suppression in a Natural Population
    TLDR
    It is demonstrated that absence of male killing by wBol1 is associated with dominant zygotic suppression of the action of the male killer, leading to the conclusion that some species that do not currently express a male killer may have done so in the past, and thus that more species have had their biology affected by these parasites than previously believed.
