choice, has emerged as a widespread evolutionary force among polyandrous animals …

Seminal fluid is often assumed to have just one function in mammalian reproduction,
delivering sperm to fertilize oocytes. But seminal fluid also transmits signaling agents that …

Maternal effects are now universally recognised as a form of nongenetic parental influence
on offspring but, until recently, paternal effects were regarded as an anomaly. Although it is …

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 …

It is well known that sexual selection can target reproductive traits during successive pre‐
and post‐mating episodes of selection. A key focus of recent studies has been to understand …
