Female cooperation, consortship maintenance, and male mating success in savanna baboons
Article Abstract:
In baboons, female choice is not restricted either by female competition or by male sexual subjugation and mount rejection by females does not obstruct male ejaculation or result in male abandonment. Female reproductive techniques are possibly designed to facilitate mating with multiple males so as to increase the probability that a minimum of one male will form an affiliative bond with her offspring. The competition costs by males for females who like them as mates can be overcome by the benefit of enhanced consortship duration by female cooperation.

Male-male competition, paternity certainty and copulation calls in female baboons
Article Abstract:
Recent research data on chacma baboons concluded that the function of their copulation calls is to promote sperm competition in order to reduce the risk of infanticide and/or obtain good genes for male offspring. Since infanticide in baboons may be associate mostly with the arrival of immigrant males, it may be these males to whom the calls are primarily directed. This may hold for calls performed in unimale or multimale groups, though an intra-group source of threat is clearly present in multimale groups.

Copulation calls and paternity in chacma baboons
Article Abstract:
Data from a study on the functions of copulation-call length and placement of chacma baboons concluded that these were involved with the elicitation of sperm competition by raising the probability of male consort turnover at the time of ovulation. However, there is scant evidence of sperm competition between males around the time of female ovulation. Additional data from other populations will be needed, and if not, it must be acknowledged that the signals are not functional in all populations.
