Good genes, oxidative stress and condition-dependent sexual signals.
The immune and the detoxication systems of animals are characterized by allelic polymorphisms, which underlie individual differences in ability to combat assaults from pathogens and toxic compounds. Previous studies have shown that females may improve offspring survival by selecting mates on the basis of sexual ornaments and signals that honestly reveal health. In many cases the expression of t...
متن کاملSwingin' in the rain: condition dependence and sexual selection in a capricious world.
Signals used in mate attraction are predicted to be highly condition dependent, and thus should be sensitive to environmental contributions to condition. However, the effects of temporal fluctuations in the environment on sexual selection in long-lived animals have been largely ignored. Female superb fairy-wrens, Malurus cyaneus, use the time that males moult into nuptial plumage prior to the o...
متن کاملCondition Dependence and Fitness Consequences of Sexual Traits in Zebra Finches
The developmental stress hypothesis offers a mechanism to maintain honesty of sexually selected traits, since only high genetic quality individuals will be able to fully develop ornaments in the face of early stress. The zebra finch has become a model species in studies of developmental stress. However, results have been mixed and a unifying perspective is missing. Using a quantitative genetic ...
متن کاملSexual dimorphism and condition dependence in the anal pad of the small Indian mongoose (Herpestes auropunctatus)
Secondary sexual traits tend to be sexually dimorphic, and theory predicts that such traits should also be conditiondependent in a sex-specific manner. We investigate these phenomena in a field study of the small Indian mongoose (Herpestes auropunctatus (Hodgson, 1836); formerly Herpestes javanicus (É. Geoffroy Saint-Hillaire, 1818)), in the first attempt at understanding secondary sexual trait...
