“…Here, we report on local recruitment and first-year reproductive performance of maternal half-siblings in the coal tit, a territorial socially monogamous passerine with high levels of EPP (Lubjuhn et al 1999b;Dietrich 2001). If female coal tits engage in extra-pair matings to obtain genetic benefits for their offspring, we predict that EPO will show higher recruitment and/or better first-year reproductive performance than WPO half-sibs.…”

Whether female birds choose extra-pair mating partners to obtain genetic fitness benefits is intensely debated. The most straightforward and crucial test of 'good genes' models of female extra-pair mating is the comparison of naturally 'cross-fostered' maternal half-siblings sharing the same rearing environment as any systematic differences in performance between the two categories of offspring phenotype can be attributed to differential paternal genetic contribution. We analysed local recruitment and first-year reproductive performance of maternal half-siblings in the coal tit (Parus ater), a passerine bird with high levels of extra-pair paternity. We provide a highly comprehensive measure of the long-term fitness consequences of female extra-pair matings based on a large sample of 736 within-pair offspring (WPO) and 368 extrapair offspring (EPO) from 91 first and 55 second broods, from which 132 breeders recruited into the study population. In contrast to predictions derived from 'good genes' models, we found no differences in local recruitment and seven parameters of first-year reproductive performance when comparing WPO and EPO. These results question the universal validity of findings in other bird species supporting 'good genes' models, particularly as they are based on the best approximation to female fitness obtained so far.

“…They are socially monogamous (Glutz von Blotzheim and Bauer 1993), but show comparatively high rates of extrapair paternity (see appendix in Griffith et al 2002). Within the well-investigated genus Parus (chickadees and titmice), these are the highest rates by far (Lubjuhn et al 1999b;Dietrich et al 2004).…”

Paternal Genetic Effects on Offspring Fitness Are Context Dependent: Within the Extrapair Mating System of a Socially: Monogamous Passerine

Abstract. Avian extrapair mating systems provide an interesting model to assess the role of genetic benefits in the evolution of female multiple mating behavior, as potentially confounding nongenetic benefits of extrapair mate choice are seen to be of minor importance. Genetic benefit models of extrapair mating behavior predict that females engage in extrapair copulations with males of higher genetic quality compared to their social mates, thereby improving offspring reproductive value. The most straightforward test of such good genes models of extrapair mating implies pairwise comparisons of maternal half-siblings raised in the same environment, which permits direct assessment of paternal genetic effects on offspring traits. But genetic benefits of mate choice may be difficult to detect. Furthermore, the extent of genetic benefits (in terms of increased offspring viability or fecundity) may depend on the environmental context such that the proposed differences between extrapair offspring (EPO) and within-pair offspring (WPO) only appear under comparatively poor environmental conditions. We tested the hypothesis that genetic benefits of female extrapair mate choice are context dependent by analyzing offspring fitness-related traits in the coal tit (Parus ater) in relation to seasonal variation in environmental conditions. Paternal genetic effects on offspring fitness were context dependent, as shown by a significant interaction effect of differential paternal genetic contribution and offspring hatching date. EPO showed a higher local recruitment probability than their maternal half-siblings if born comparatively late in the season (i.e., when overall performance had significantly declined), while WPO performed better early in the season. The same general pattern of context dependence was evident when using the number of grandchildren born to a cuckolding female via her female WPO or EPO progeny as the respective fitness measure. However, we were unable to demonstrate that cuckolding females obtained a general genetic fitness benefit from extrapair fertilizations in terms of offspring viability or fecundity. Thus, another type of benefit could be responsible for maintaining female extrapair mating preferences in the study population. Our results suggest that more than a single selective pressure may have shaped the evolution of female extrapair mating behavior in socially monogamous passerines.

The power of DNA fingerprinting is due to comparatively high mutation rates of minisatellite and microsatellite DNA sequences. Studying the mating system of a parrot species (Burrowing Parrots, Cyanoliseus patagonus) using oligonucleotide probes, we observed mutation rates that are several orders of magnitude higher than those described anywhere in the literature. Most plausibly, the respective values are based on 3-4 loci with mutation rates of up to 100%.
