In species with separate sexes, females and males often differ in their morphology,
physiology and behaviour. Such sex‐specific traits are functionally linked to variation in …

The role of non-gametic components of the ejaculate (seminal fluid) in fertility and sperm
competitiveness is now well established. Surprisingly, however, we know far less about …

Interactions between sperm and the female reproductive tract (FRT) are critical to
reproductive success and yet are poorly understood. Because sperm complete their …

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 …

Seminal fluid proteins (SFPs) are a group of reproductive proteins that are among the most
evolutionarily divergent known. As SFPs can impact male and female fitness, these proteins …

Sexual selection has been studied as a major evolutionary driver of animal diversity for
roughly 50 years. Much evidence indicates that competition for mates favors elaborate …

Seminal fluid is rich in sugars, but their role beyond supporting sperm motility is unknown. In
this study, we found Drosophila melanogaster males transfer a substantial amount of a …

The predicted temperature increase caused by climate change is a threat to biodiversity.
Across animal taxa, male reproduction is often sensitive to elevated temperatures leading to …

Background The female reproductive tract is exposed directly to the male's ejaculate,
making it a hotspot for mating-induced responses. In Drosophila melanogaster, changes in …

Background Bemisia tabaci, a significant agricultural pest in Asia, contains distinct genetic
groups, Asia-1 and Asia II-1. Understanding its reproductive biology, particularly the role of …
