For sexual selection to act on a given sex, there must exist variation in the reproductive
success of that sex as a result of differential access to mates or fertilisations. The …

Møller and Birkhead (1992, 1993) reported that extra-pair copulations (EPCs) occur more
frequently in colonial than dispersed nesting birds. We comprehensively reviewed published …

Variation in the extent of sexual dimorphism among bird species is traditionally attributed to
differences in social mating system. However, there are many different forms of dimorphism …

Shorebirds are the most visible inhabitants of coastal wetlands worldwide. Many undertake
spectacularly long flights between their wintering and breeding grounds, embodying the …

Abstract The Evolution of Avian Breeding Systems deals with three of the most conspicuous
and fascinating aspects of the reproductive biology of birds: sexual selection, parental care …

Sex-role reversal occurs when females compete more intensely than males for access to
mates. In this paper, we survey the occurrence of sex-role reversal in vertebrates: we focus …

Paternity has been hypothesized to be related to the evolution of paternal care because (1)
there should be selection for males not to invest in broods with an uncertain parentage, or …

To understand interspecific patterns in the strength of sexual selection, variation in the costs
and benefits of exercising mate choice needs to be evaluated. One manifestation of sexual …

It has been argued recently that the combination of male–only parental care and classical
polyandry in birds is the most interesting and yet the least understood of all avian breeding …

A stage model traces key behavioural tactics and life–history traits that are involved in the
transition from promiscuity with no parental care, the mating system that typifies reptiles, to …
