Sexual selection in socially-structured, polyandrous populations: Some insights from the fowl

摘要: Abstract Sexual selection is widely recognized as the evolutionary agent driving male exaggeration and strategies of intrasexual competition over reproductive opportunities. Two advances have characterized development our understanding sexual in recent years. The first was realization that can extend to post-copulatory episodes whenever females mate with multiple males (polyandry). second concerns operation structured population light increasing evidence populations are often non-randomly assembled. Populations domestic fowl (Gallus domesticus) red junglefowl gallus), which typically socially-structured polyandrous, offered a convenient vertebrate model system study patterns mechanisms selection, providing helpful counterpoint studies socially monogamous systems. Here, we review way operates these populations, emphasis on work focusing interrelated implications polyandry social structure.
