Age trajectories in extra‐pair siring success suggest an effect of maturation or early‐life experience

E Schlicht, B Kempenaers - Journal of Evolutionary Biology, 2023 - academic.oup.com
Across birds, male age is the most consistent predictor of extra‐pair siring success, yet little
is known about age effects on paternity over the lifetime of individuals. Here, we use data …

Reduced fitness in progeny from old parents in a natural population

Male age is associated with extra-pair paternity, but not with extra-pair mating behaviour

A Girndt, CWT Chng, T Burke, J Schroeder - Scientific Reports, 2018 - nature.com
Extra-pair paternity is the result of copulation between a female and a male other than her
social partner. In socially monogamous birds, old males are most likely to sire extra-pair …

Extra‐pair paternity and sexual dimorphism in birds

M Valcu, C Valcu, B Kempenaers - Journal of Evolutionary …, 2023 - academic.oup.com
