Cost of Female Intrasexual Aggression in Terms of Offspring Quality: A CrossFostering Study
Aggression is a key component of intrasexual competition in both sexes; however, our understanding of the relative costs and benefits of this behavior is heavily biased toward males (Andersson 1994; Searcy & Nowicki 2005). In spite of the assumption that high levels of intrasexual female aggression are costly to females, there is little empirical evidence quantifying the fitness costs of female...

Human females have a particular proclivity for using indirect aggression, which is typically directed at other females, especially attractive and sexually available females, in the context of intrasexual competition for mates.

متن کاملMaintenance of variation in sexually selected traits in females: a case study using intrasexual aggression in tree swallows Tachycineta bicolor
A fundamental question in evolutionary biology is how phenotypic variation is maintained in the face of selection that ought to deplete that variation. Much research has investigated this question in traits favored via sexual selection in males, with a common solution implicating the condition dependence of sexually selected phenotypes. Despite growing interest in sexual selection on females, i...
متن کاملThe number of subordinates moderates intrasexual competition among males in cooperatively breeding meerkats.
For dominant individuals in cooperatively breeding species, the presence of subordinates is associated with both benefits (i.e. increased reproductive output and other group-living benefits) and costs (i.e. intrasexual competition on reproduction). The biological market theory predicts that dominant individuals are tolerant to same-sex group members when there are only a few subordinates, so as...
متن کاملSex differences and developmental effects of oxytocin on aggression and social behavior in prairie voles (Microtus ochrogaster).
Various hormones, including sex steroids and neuropeptides, have been implicated in aggression. In this study we examined (1) sex differences in intrasexual aggression in naïve prairie voles; (2) the effects of developmental manipulations of oxytocin on intrasexual aggression; and (3) changes in patterns of intrasexual aggression after brief exposure to an animal of the opposite sex. Within 24 ...
