Do the ages of parents or helpers affect offspring fitness in a cooperatively breeding bird?

Cooper, Eve; Bonnet, Timothee; Osmond, Helen; Cockburn, Andrew; Kruuk, Loeske


Age-related changes in parental phenotypes or genotypes can impact offspring fit-ness, but separating germline from nongermline transgenerational effects of ageing is difficult for wild populations. Further, in cooperatively breeding species, in addi-tion to parental ages, the age of ‘helpers’ attending offspring may also affect juvenile performance. Using a 30-year study of a cooperative breeder with very high rates of extra-pair paternity, the superb fairy-wren...[Show more]
