Abstract: | This paper presents copulatory data gathered on a free-ranging population of stumptail macaques (Macaca arctoides) in Mexico. The study found evidence for seasonal clumping of matings, with the peak in the month of February, and that matings are more common in the afternoon, when measuring diurnal changes. It also found that males require an average of one and a half mounts before ejaculating, and mating among females is distributed unequally, when the measurement is between those females that mated. Furthermore, male dominance rank and male-female affiliation are both positively correlated with mating frequency. Variations between this study and captive studies are minimal. The variances that do occur may be explained by differences in the research settings or the individual differences in the subjects' behavior across studies. |
