“…The body weights reported here (table 3) are in agreement with most of the weights reported in the literature, but much lower than those reported by Fairbanks and McGuire [2], Kingdon [7], and Fedigan and Fedigan [11], In our sample, significant differ ences in body weights among the 4 sites were found for females but not for males [14]. These differences may reflect increased sensi tivity of females to environmental differences due to the demands of reproduction.…”

“…Although there are cases in which rank is related to reproductive success (Sugiyama and Oshawa, 1982;Whitten, 1983;Fairbanks and McGuire, 1984;Janson, 1985), there are often cases in which there is no rank-reproduction relationship (Takahata et al, 1999) or when the relationship is dependant on particular ecological circumstances, such as food distribution or availability (Sugiyama and Oshawa, 1982;Whitten, 1983;van Noordwijk and van Schaik, 1999). Thus, the ability of females to negotiate social situations may be more important to reproductive success than their ability to aggressively compete.…”

In strepsirrhine primates, the accessory olfactory system plays an important role in intrasexual competition. However, it does not play the same role in most haplorhines. In these primates, the main olfactory system and neocortex may have evolved to serve similar functions as the accessory olfactory system in strepsirrhines. To test these hypotheses, the relative size of the main olfactory bulb and neocortex were analyzed for associations with male and female competition frequency and intensity (categorized as low or high). Because neocortex size and competition intensity are associated with diet, only frugivorous species were analyzed (catarrhines, n ϭ 7; platyrrhines, n ϭ 8). Neither the size of the main olfactory bulb nor the neocortex was significantly associated with intrasexual competition among males. However, neocortex size was related to the frequency of female competition. Because the main olfactory system and neocortex both serve multiple purposes, there may not be a single behavioral variable that has selected for their size. Furthermore, categorization of male and female competition intensity reflects physically aggressive behavior. Use of the neocortex for social manipulation may allow males to obtain copulations and females to obtain food resources despite poor physical fighting abilities and low dominance rank.

“…However, there are also populations in which no changes in fertility or in the length of interbirth intervals are associated with advancing age (Fairbanks and McGuire, 1984;Gouzoules et al, 1982). Fairbanks and McGuire (1984) have found normative e f ? ects of infant loss on the length age for in P ant loss is about four months.…”

Sources of variation in interbirth intervals among captive bonnet macaques (Macaca radiata)

Female fitness is a function of variation in the length of females' reproductive careers, the viability of their offspring, and the frequency with which they give birth. Infant loss shortens interbirth intervals in most primate species, but we know considerably less about other factors that contribute to variation in the length of interbirth intervals within groups. In one large captive group of bonnet macaques, maternal parity, age, experience, family size, and recent reproductive history are all associated with variation in the length of intervals that follow the birth of surviving infants. Primiparous females have the longest interbirth intervals, while multiparous females who have produced surviving infants in the past and have raised their last infant successfully have the shortest interbirth intervals. Infant sex and maternal rank have no direct effect upon the length of interbirth intervals. One of the underlying causes of variation in the length of interbirth intervals after surviving births seems to be variation in the timing of conceptions among females. Females who conceive early in the mating season tend to have shorter interbirth intervals than other females. However, females who are multiparous, experienced, and have recently raised infants have late conceptions and short interbirth intervals.
