Sexual selection and mate choice.
Sexual selection, natural selection and quality advertisement
TLDR
Both mating advantage and mortality disadvantage increase with ornament size, and balance at its optimal development, and if a given adornment reduces survival most in low quality phenotypes, the optimum increases with phenotypic quality.
Ultraviolet sexual dimorphism and assortative mating in blue tits
TLDR
It is concluded that blue tits are markedly sex dimorphic in their own visual world, and that UV/violet coloration probably plays a role in blue tit mate acquisition.
Female choice selects for extreme tail length in a widowbird
TLDR
It is reported here that males in which the tail was experimentally elongated showed higher mating success than males having normal or reduced tails: males with shortened tails held their territories as long as did other males.
Multiple Receivers, Multiple Ornaments, and a Trade‐off between Agonistic and Epigamic Signaling in a Widowbird
TLDR
It is proposed that the “multiple receiver hypothesis” can explain the coexistence of multiple handicap signals, and the trade‐off between signal expressions might contribute to the inverse relation between nuptial tail elongation and coloration in the genus Euplectes (bishops and widowbirds).
SEXUAL SELECTION AND THE EVOLUTION OF SONG
TLDR
The question of why listeners have evolved to respond to song in the contexts of female choice and male contest is examined, and ideas and evidence on the evolution of relationships betweensong and female choice, and between song and success in male contests are reviewed.
EVOLUTION OF CONDITION‐DEPENDENT SEX ORNAMENTS AND MATING PREFERENCES: SEXUAL SELECTION BASED ON VIABILITY DIFFERENCES

  • 1 July 1986
TLDR
The possibility that the evolution of mating preferences and secondary sex traits can be based on heritable differences in viability is examined with a three‐locus model, based on a monogamous mating system that precludes such a Fisherian mating advantage being required.
Relatedness and the Evolution of Conspecific Brood Parasitism
TLDR
This inclusive‐fitness model of parasitism, structured as a game between host and parasite, suggests that both females can gain inclusive fitness and that host‐parasite relatedness can therefore facilitate the evolution of CBP.
Inclusive fitness theory and eusociality
TLDR
It is argued that inclusive fitness theory has been of little value in explained the natural world, and that it has led to negligible progress in explaining the evolution of eusociality, but these arguments are based upon a misunderstanding of evolutionary theory and a misrepresentation of the empirical literature.
