Facultative adjustment of the offspring sex ratio and male attractiveness: a systematic review and meta‐analysis
Females can benefit from mate choice for male traits (e.g. sexual ornaments or body condition) that reliably signal the effect that mating will have on mean offspring fitness. These male‐derivedExpand

Fitness consequences of artificial selection on relative male genital size
Male genitalia often show remarkable differences among related species in size, shape and complexity. Across poeciliid fishes, the elongated fin (gonopodium) that males use to inseminate femalesExpand

Female fiddler crabs settle for less: the travel costs of mate choice
Females often have strong preferences for the most attractive males that provide the greatest benefits. However, searching for and sampling potential mates is costly. Females are therefore expectedExpand

Investigating the ‘dear enemy’ phenomenon in the territory defence of the fiddler crab, Uca mjoebergi
Territory owners often respond with greater aggression to strangers than to neighbouring individuals, a phenomenon known as the ‘dear enemy’ effect. As strangers are usually ‘floating’ individualsExpand

The battle of the sexes? Territory acquisition and defence in male and female fiddler crabs
In many territorial species males invest substantially in weapons, which they use in fights to acquire and maintain territories that ultimately give them access to females. Females often live withinExpand

Male fiddler crabs prefer conspecific females during simultaneous, but not sequential, mate choice
Mate choice is potentially beneficial whenever prospective mates vary in quality, but when mates are encountered sequentially the cost of rejecting a current mating opportunity affects the netExpand

Sex Ratio Bias Leads to the Evolution of Sex Role Reversal in Honey Locust Beetles
The reversal of conventional sex roles was enigmatic to Darwin, who suggested that it may evolve when sex ratios are female biased [1]. Here we present direct evidence confirming Darwin's hypothesis.Expand

Artificial selection on male genitalia length alters female brain size
Male harassment is a classic example of how sexual conflict over mating leads to sex-specific behavioural adaptations. Females often suffer significant costs from males attempting forced copulations,Expand

The measurement of sexual selection on females and males
As in any field of research, the study of sexual selection is subject to ongoing debate over definitions and interpreta- tions of the fundamental concepts involved. These arguments generally promoteExpand

Mate choice and the operational sex ratio: an experimental test with robotic crabs
The operational sex ratio (OSR: sexually active males: receptive females) predicts the intensity of competition for mates. It is less clear, however, under what circumstances, the OSR predicts theExpand
