A hypothesis for the evolution of androdioecy: the joint influence of reproductive assurance and local mate competition in a metapopulation

Abstract:

In a subdivided population with recurrent local extinction and re-colonisation, competition amongst related pollen or sperm to fertilise ovules or eggs (`local mate competition') is expected to select for female-biased sex allocation. Population turnover should also select against unisexuality in favour of self-fertile cosexuality, because males and females are unable to establish new populations on their own (`Baker's Law'). Here I argue that androdioecy, a rare breeding system in which male...
