Female competition and its evolutionary consequences in mammals.
Following Darwin's original insights regarding sexual selection, studies of intrasexual competition have mainly focused on male competition for mates; by contrast, female reproductive competition has received less attention. Here, we review evidence that female mammals compete for both resources and mates in order to secure reproductive benefits. We describe how females compete for resources su...
متن کاملPostcopulatory sexual selection: Darwin's omission and its consequences.
In one of his few major oversights, Darwin failed to appreciate that male-male competition and sexual selection can continue even after copulation has begun. The postcopulatory equivalents of both direct male-male battles (sperm competition) and female choice (cryptic female choice) occur within the female's body. Recognition of this hidden, but intense, sexual competition provides new insights...
متن کاملSexual violence and its health consequences for female children in Swaziland: a cluster survey study.
BACKGROUND Despite concern, few studies have been done about sexual violence against girls younger than 18 years of age in sub-Saharan Africa. We report the prevalence and circumstances of sexual violence in girls in Swaziland, and assess the negative health consequences. METHODS We obtained data from a nationally representative sample of girls and women aged 13-24 years from selected househo...
متن کاملFemale ornamentation in Malurus fairy-wrens: a hidden evolutionary gem for understanding female perspectives on social and sexual selection
Phylogeny, ecological environment, social organisation, and mating system are expected to affect degree of female ornamentation, either directly or indirectly, but our understanding of how female ornaments respond to these forces remains incomplete. This article evaluates the evolutionary history and adaptive significance of three putative ornaments – plumage colouration, bill colouration and t...
متن کاملSexual selection in prehistoric animals: detection and implications.
Many fossil animals bear traits such as crests or horns that probably functioned as sexually selected signals or weapons. Interpretations of these structures as functioning in mate choice or intrasexual contests are often controversial, with interpretations based on biomechanics or physiology being favoured by many. Although testing hypotheses based on sexual selection can be difficult, especia...
