Parasitic infection and oxidative status are associated and vary with breeding activity in the Seychelles warbler
Parasites can have detrimental effects on host fitness, and infection typically results in the stimulation of the immune system. While defending against infection, the immune system generates toxic oxidants; if these are not sufficiently counteracted by the antioxidant system, a state of oxidative stress can occur. Here, we investigated the relationship between parasitic infection-using malaria...
متن کاملSpatio-temporal variation in territory quality and oxidative status: a natural experiment in the Seychelles warbler (Acrocephalus sechellensis)
1. Fluctuations in the quality of the habitat in which an animal lives can have major consequences for its behaviour and physiological state. In poor-quality habitat with low food availability, metabolically intensive foraging activity is likely to result in increased generation of reactive oxygen species, while scarcity of food can lead to a weakening of exogenously derived antioxidant defence...
متن کاملHeterozygosity-fitness correlations in a bottlenecked island species: a case study on the Seychelles warbler.
We used capture-mark-recapture models to investigate the effects of both individual and parental heterozygosity, measured at microsatellite loci on the survival of Seychelles warblers (Acrocephalus sechellensis), an endemic island species which went through a severe population bottleneck in the middle of the last century. We found that an individual's survival was not correlated with multilocus...
متن کاملS15-3 Fitness consequences of cooperative breeding in the Seychelles warbler
Inclusive fitness benefits have been suggested as the selective force behind the evolution of cooperative breeding. Assessing the benefits accrued to individual males and females is crucial to understanding the sex-specific helping behavior observed in many cooperatively breeding species. We investigated the fitness consequences of male and female helping behavior in the Seychelles warbler (Acr...
متن کاملLong-term fitness benefits of egg sex modification by the Seychelles warbler
Sex-ratio theory states that if the fitness costs to the parents of producing one offspring's sex relative to the other are higher, parents should discount these costs by producing fewer individuals of the more costly sex. In the co-operatively breeding Seychelles warbler (Acrocephalus sechellensis) mothers adaptively modify the sex of their single egg toward daughters, the helping sex, when li...
