Developmental stress increases reproductive success in male zebra finches.
There is increasing evidence that exposure to stress during development can have sustained effects on animal phenotype and performance across life-history stages. For example, developmental stress has been shown to decrease the quality of sexually selected traits (e.g. bird song), and therefore is thought to decrease reproductive success. However, animals exposed to developmental stress may com...
متن کاملReproductive success and symmetry in zebra finches
Fluctuating asymmetries are small, random developmental accidents in morphological traits that would otherwise be described as being bilaterally symmetric. Experimental evidence indicates that in mate choice situations individuals possessing symmetric arbitrary traits or symmetric secondary sexual characters are preferred over those with larger asymmetries. This experiment investigated the effe...
متن کاملReproductive impairment in zebra finches (Taeniopygia guttata).
The effects of polychlorinated biphenyls (PCBs) as compounds that may disrupt endocrine activity and, consequently, alter reproductive performance were investigated in altricial zebra finches (Taeniopygia guttata). The breeding performance and breeding cycle of zebra finches differed significantly between nonexposed birds and those experimentally pulse-exposed to Aroclor 1248, a PCB compound (4...
متن کاملKin recognition and adjustment of reproductive effort in zebra finches.
The differential allocation theory predicts that females should invest more in offspring produced with attractive partners, and a number of studies support this prediction in birds. Females have been shown to increase reproductive investment when mated to males showing elaborated sexual traits. However, mate attractiveness might also depend on the interaction between male and female genotypes. ...
متن کاملMaternal effects in quail and zebra finches: Behavior and hormones.
Maternal effects are influences of parents on offspring phenotype occurring through pathways other than inherited DNA. In birds, two important routes for such transmission are parental behavior and non-DNA egg constituents such as yolk hormones. Offspring traits subject to parental effects include behavior and endocrine function. Research from the Adkins-Regan lab has used three avian species t...
