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… 

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.

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.

Persistence of a Wolbachia-driven sex ratio bias in an island population of Eurema butterflies

TLDR
The discrepancies observed between sex ratios of captive individuals and sex ratios deduced from wFem infection frequencies among females can be explained by a plastic behavioural change of males and females in response to the shift of sex ratios.

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.

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.

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.

Hidden suppression of sex ratio distortion suggests Red queen dynamics between Wolbachia and its dwarf spider host

TLDR
It is determined that one of these populations demonstrates a higher suppressing capability towards Wolbachia despite having a similar population sex ratio, suggesting that spider and endosymbiont are locked in so‐called red queen dynamics where, despite continuous coevolution, average fitness remains the same, hence hiding the presence of the suppressor.

Rapid comeback of males: evolution of male-killer suppression in a green lacewing population

TLDR
It is demonstrated that a nuclear suppressor of a cytoplasmic male killer has spread rapidly in a population of the green lacewing Mallada desjardinsi, and it is suggested that quick events of male recovery occur more commonly than is generally appreciated.

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.

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.
