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 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 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 coloration indicates female reproductive capacity in blue tits.
It is poorly understood whether female morphological and behavioural traits can be used as 'signals'. In particular, experimental tests of the hypothesis that female ornaments reflect quality are scarce. Here, we experimentally examine whether female plumage coloration might signal maternal quality in the blue tit, Cyanistes caeruleus by forcing half of the females breeding in our population to...
متن کاملI Who Can Insure Against the Climate ?
First, it is important to understand that the effects of increasing atmospheric carbon dioxide content are uncertain, and may be as much as an order of magnitude less than is assumed by the computer models. The strength of various feedback effects is also uncertain. But the most important point is that computer models of the state of climate in 100 years’ time are viewed by their creators as sc...
