Costly Infidelity: Low Lifetime Fitness of Extra-Pair Offspring in a Passerine Bird
... Our study is not the first to challenge hypotheses positing that females gain indirect genetic benefits from producing EPO. Although some empirical studies support these hypotheses, two meta-analyses of 11 and 10 ...

Extra-pair copulation and paternity defense in the hihi (or stitchbird) Notiomystis cincta
... Paired males attempted to prevent other males from forcibly copulating with their partners. Such forced copulations were sometimes successful despite the efforts of paired males (Ewen et al., 1999). Knowledge of EPCs may ...

Genetic evidence of extra-pair paternity and intraspecific brood parasitism in the monk parakeet
... Variations in intraspecific reproductive strategies be- tween native and invasive sites may result from an adap- tive response to environmental changes or population density [14]. Although inconclusive, there is good ...

Levels of extra-pair paternity are associated with parental care in penduline tits (Remizidae)
... Two factors have been identified that are likely to have implications for the evolutionary relationship between mating and parental care systems. The first is female promiscuity and its potential influence on the fitness ...

The influence of nonrandom extra-pair paternity on heritability estimates derived from wild pedigrees
