AbstractPaternity exclusion analysis was employed to estimate the reproductive success (RS) of 32 males who experienced at least one breeding season over the age of four years between 1977 and 1991 in a captive group of rhesus macaques (Macaca mulatta). Although three different males held alpha rank during the period, the male dominance hierarchy remained relatively stable even when the number of males was high. Average dominance rank and overall RS of males while in the group were strongly correlated. However, during most years the correlation between male dominance rank and RS was not statistically significant because males who achieved high rank 1)were those who experienced relatively high RS as lower ranking subadults and 2) maintained high dominance rank after experiencing a sustained decline in RS. Correlations between male dominance rank and RS were highest when the number of subadult males entering the dominance hierarchy was increasing and one or a very few males were least effective in monopolizing females. These results are not consistent with expectations based solely on the priority of access model of intrasexual selection. Female choice, as exemplified by the preference of females for mating with young males that are rising in rank, might also influence the evolution of social dominance in rhesus macaques.

AbstractMale rhesus macaques on Cayo Santiago use rank-dependent alternative reproductive tactics. High-ranking males can form long-term consorts and guard female mates while low-ranking males frequently resort to quick copulations under the cover of vegetation. No single reproductive tactic provided the Group S males with a definitive reproductive advantage during the one-year study. Males using the long-term tactic and the quick, stealth tactic sired five offspring each, but fewer males used the long-term consort tactic. Males using the long-term reproductive tactic have significantly greater mating success than males using the quick, sneaky tactic, and may have greater reproductive success. The highest-ranking males who form long-term consorts had the greatest degree of reproductive success. This indicates that for the highest-ranking males, forming long-term consorts is the most effective reproductive tactic. The effectiveness of alternative tactics for high-ranking males (i.e. consort disruption and possessive following) was equivocal. Consort disruption had no immediate effect on reproductive success. Possessive following may have resulted in the siring of two offspring by the alpha male, but was ineffective in other cases, where the females were inseminated by subordinate males. The effectiveness of the quick, furtive tactic was demonstrated by the siring of 45% of the infants by males who used this tactic.

AbstractSexual selection favours traits that increase reproductive success via increased competitive ability, attractiveness, or both. Male rhesus macaque (Macaca mulatta) morphological traits are likely to reflect the effects of multiple sexual selection pressures. Here, we use a quantitative genetic approach to investigate the production and maintenance of variation in male rhesus macaque morphometric traits which may be subject to sexual selection. We collected measurements of body size, canine length, and fat, from 125 male and 21 female free-ranging rhesus macaques on Cayo Santiago. We also collected testis volumes from males. We used a genetic pedigree to calculate trait heritability, to investigate potential trait trade-offs, and to estimate selection gradients. We found that variation in most male morphometric traits was heritable, but found no evidence of trait trade-offs nor that traits predicted reproductive success. Our results suggest that male rhesus macaque morphometric traits are either not under selection, or are under mechanisms of sexual selection that we could not test (e.g. balancing selection). In species subject to complex interacting mechanisms of selection, measures of body size, weaponry, and testis volume may not increase reproductive success via easily-testable mechanisms such as linear directional selection.
