The past two decades have seen extensive growth of sexual selection research. Theoretical
and empirical work has clarified many components of pre-and postcopulatory sexual …

Sperm are produced in astronomical numbers compared with eggs, and there is good
evidence that sperm competition is the force behind the evolution of many tiny sperm …

The book aims to integrate our understanding of mammalian societies into a novel synthesis
that is relevant to behavioural ecologists, ecologists, and anthropologists. It adopts a …

Following Darwin's original insights regarding sexual selection, studies of intrasexual
competition have mainly focused on male competition for mates; by contrast, female …

The female reproductive tract is where competition between the sperm of different males
takes place, aided and abetted by the female herself. Intense postcopulatory sexual …

In spite of recent interest in sexual selection in females, debate exists over whether traits that
influence female–female competition are sexually selected. This review uses female–female …

Selective harvesting regimes are often implemented because age and sex classes
contribute differently to population dynamics and hunters show preferences associated with …

We present estimates of the selection on and the heritability of a male secondary sexual
weapon in a wild population: antler size in red deer. Male red deer with large antlers had …

Sexual selection can explain major micro‐and macro‐evolutionary patterns. Much of current
theory predicts that the strength of sexual selection (i) is driven by the relative abundance of …

Competition for fertile females determines male reproductive success in many species. The
priority of access model predicts that male dominance rank determines access to females …
