The distinct reproductive roles of males and females, which for many years were
characterised in terms of competitive males and choosy females, have remained a central …

We review the current status of three well–established models (direct benefits, indirect
benefits and sensory drive) and one newcomer (antagonistic chase–away) of the evolution …

Sexual reproduction is associated with the evolution of anisogamy and sperm-producing
males and egg-laying females. The ensuing competition for mates has led to sexual …

Empirical studies of sexual selection typically focus on one of the two mechanisms of sexual
selection without integrating these into a description of total sexual selection, or study total …

Body size is a classic quantitative trait with evolutionarily significant variation within many
species. Locating the alleles responsible for this variation would help understand the …

Rapid evolution of reproductive traits has been attributed to sexual selection arising from
interaction between the sexes. However, little is known about the nature of selection driving …

Healthy males are likely to have higher mating success than unhealthy males because of
differential expression of condition-dependent traits such as mate searching intensity …

In contrast to early predictions, it is now widely accepted that males incur substantive costs
from ejaculate production. Hence, males are predicted to allocate their reproductive …

The interests of males and females over reproduction rarely coincide and conflicts between
the sexes over mate choice, mating frequency, reproductive investment, and parental care …

ABSTRACT A central question in ecology and evolution is to understand why sexual
selection varies so much in strength across taxa; it has long been known that ecological …
