Male infertility, female fertility and extrapair copulations.
Females that are socially bonded to a single male, either in a social monogamy or in a social polygyny, are often sexually polyandrous. Extrapair copulations (EPC) have often been suggested or rejected, on both empirical and theoretical grounds, as an important mechanism that enables females to avoid fertility risks in case their socially bonded male is infertile. Here, we explore this possibil...
متن کاملSexual conflict in waterfowl: why do females resist extrapair copulations?
Forced copulation is a male reproductive strategy in a variety of animals but rare among avian species, with the notable exceptions of waterfowl (family Anatidae) and at least 1 passerine species, the New Zealand stitchbird or hihi Notiomystis cincta. The presence of forced extrapair copulation in these species challenges the perception that females control extrapair copulations (EPC) across av...
متن کاملFemale Adelie Penguins Acquire Nest Material from Extrapair Males after Engaging in Extrapair Copulations
Females of a number of bird species occasionally have been recorded exchanging copulations directly for food or for access to food resources (Lack 1940, Brown 1967). For example, Wolf (1975) found that male Purple-throated Caribs (Eulampis jugularis) defend groups of flowers from conspecifics but allow females access in exchange for copulations. Similarly, in monogamous Red-billed Gulls (Larus ...
متن کاملA bird distribution model for ring recovery data: where do the European robins go?
For the study of migratory connectivity, birds have been individually marked by metal rings for more than 100 years. The resulting ring recovery data have been compiled in numerous bird migration atlases. However, estimation of what proportion of a particular population is migrating to which region is confounded by spatial heterogeneity in ring recovery probability. We present a product multino...
