Darwin's theory of sexual selection fundamentally changed how we think about sex and
evolution. The struggle over mating and fertilization is a powerful driver of diversification …

Postcopulatory sexual selection (PCSS), comprised of sperm competition and cryptic female
choice, has emerged as a widespread evolutionary force among polyandrous animals …

Sexual selection has the potential to decrease mean fitness in a population through an array
of costs to nonsexual fitness. These costs may be offset when sexual selection favors …

ABSTRACT A central paradigm in evolutionary biology is that the fundamental divergence in
the fitness interests of the sexes ('sexual conflict') can lead to both the evolution of sex …

Across internally fertilising species, males transfer ejaculate proteins that trigger wide-
ranging changes in female behaviour and physiology. Much theory has been developed to …

Sperm production and allocation strategies have been a central concern of sperm
competition research for the past 50 years. But during the 'sexual cascade'there may be …

Sex peptide (SP), a seminal fluid protein of Drosophila melanogaster males, has been
described as driving a virgin-to-mated switch in females, through eliciting an array of …

Ageing and sexual selection are intimately linked. There is by now compelling evidence
from studies performed across diverse organisms that males allocating resources to mating …

Background Sexual dimorphism in immunity is believed to reflect sex differences in
reproductive strategies and trade-offs between competing life history demands. Sexual …

Longitudinal measurements of food intake remain a challenge in Drosophila studies of
nutrition and behavior. Here, we report an improved method for measuring fly food intake …
