Sexual dimorphism is presumed to reflect adaptive divergence in response to selection
favouring different optimal character states in the two sexes. Here, we analyse patterns of …

When females mate with multiple partners, the risk of sperm competition depends on female
mating history. To maximize fitness, males should adjust their copulatory investments …

Mate choice is a critical decision with direct implications for fitness. Although it has been
recognized for over 150 years, our understanding of its underlying mechanisms is still …

Sperm competition theory predicts that males should increase their expenditure on the
ejaculate with increasing risk of sperm competition, but decrease their expenditure with …

The waxy layer of the cuticle has been shown to play a fundamental role in recognition
systems of insects. The biparental burying beetle Nicrophorus vespilloides is known to have …

The ability to recognize individuals is an important aspect of social interactions, but it can
also be useful to avoid repeated matings with the same individual. The Coolidge effect is the …

Females of many species obtain benefits by mating polyandrously, and often prefer novel
males over previous mates. However, how do females recognise previous mates …

Cuticular hydrocarbons (CHCs) play an essential role in mate recognition in insects but the
form and intensity of sexual selection on CHCs has only been evaluated in a handful of …

Trade‐offs between life‐history variables can be manifested at either the phenotypic or
genetic level, with vastly different evolutionary consequences. Here, we examined whether …

Genotype‐by‐environment interactions (G× Es) describe genetic variation for phenotypic
plasticity. Recent interest in the role of these interactions in sexual selection has identified …
