Mating success in male primates: dominance rank, sperm competition and alternative strategies

Article Abstract:

The inclusion of male subadults in the sample does not increasethe probability of a Type I error because the absolute magnitude of a statisticneeded to achieve a given level of significance falls as the sample size increases. Although subadults may be low-ranking, there is no biological justification to exclude them as competitors. In any case, dominance can still be expected to play a major role in determining males' mating strategies.

Conditions for the coevolution of pair bonding and twinning(The Mating System of Callitrichid Primates, part 1)

Article Abstract:

A study of the selection process in the mating system of callitrichid primates reveals that males adopt a roving-male polygamy policy to make mating feasible. Monogamy is beneficial for females as it allows them to raise more offspring. Experimental results indicate that twinning could not have developed before male parenting in callitrichid primates. Parental care in these primates developed in response to high predation risks.
