Sexual coercion by male chimpanzees shows that female choice may be more apparent than real (2011, background): “194 If females are actively concentrating paternity in particular males to gain 195 protection from infanticide (van Schaik et al. 2000), then all females are expected to 196 initiate periovulatory copulations most frequently with the alpha male (van Schaik et al. 197 2004).”
Determinants of male reproductive success in wild long-tailed macaques (Macaca fascicularis)—male monopolisation, female mate choice or post-copulatory mechanisms? (2006, background): “In this respect, concealment of the fertile phase has been interpreted as a female strategy to hamper mate guarding in order to achieve more freedom for own reproductive decisions ( van Schaik et al. 2000; Heistermann et al. 2001).”
The efficacy of female choice in chimpanzees of the Taï Forest, Côte d’Ivoire (2006, background): “While female promiscuity suggests a lack of selectivity, upon closer examination, females appear to pursue a more complex strategy of paternity concentration and confusion (van Schaik et al. 2000; Nunn 1999; Stumpf and Boesch 2005) and this strategy appears to be successful.”
Assessment of female reproductive status by male longtailed macaques, Macaca fascicularis, under natural conditions (2004, background): “…and apes) however, differ from the general mammalian pattern in that their 62 ovarian cycles are characterised by extended follicular phases and periods of receptivity, 63 which considerably exceed the length of the fertile phase (Hrdy & Whitten 1987; Martin 64 1992; van Schaik et al. 2000).”
Selected polyandry: female choice and inter-sexual conflict in a small nocturnal solitary primate (Microcebus murinus) (2004, background): “…through male harassment, or the risk of male infanticide together with the benefits of good genes, necessitate female strategies that confuse and bias paternity, namely multiple mating and cryptic female choice (van Schaik 2000; van Schaik et al. 2000; Zeh and Zeh 2003; Wolff and Macdonald 2004).”
Sexual Selection in Primates: Mating conflict in primates: infanticide, sexual harassment and female sexuality (2004, unknown): “…are scarce, but because the variability in the follicular phase exceeds that in the luteal phase (on average by about a factor of two: see compilation in van Schaik et al., 2000), variability in the total duration of the ovarian cycle may provide a rough indication of unpredictable ovulation.”
Hedging their bets? Male and female chacma baboons form friendships based on likelihood of paternity (2010, background): “…across multiple potential caretakers, in essence confusing paternity, reducing the threat of infanticide, and providing incentives for multiple males to invest in infant care (e.g. Hrdy 1979; Ebensperger 1998; Nunn 1999; van Schaik et al. 2000; Boyko & Marshall 2009; Clarke et al. 2009).”
