Abstract

The distribution of birth dates of offspring of high-ranking adult males was compared with that of offspring of low-ranking adult males. A significantly greater number of the offspring of high-ranking males were born earlier during the birth season than were those of low-ranking males (chi 2(2) = 10.00, p less than 0.01). Higher reproductive success might be maintained by adult rhesus monkeys of high rank not only by the intensity but also by the timing of their mating activity.

摘要

将高等级成年雄性后代的出生日期分布与低等级成年雄性后代的出生日期分布进行了比较。高等级雄性的后代在出生季节中出生得明显更早，数量也显著多于低等级雄性的后代（卡方检验，自由度为2，卡方值为10.00，p < 0.01）。高等级成年恒河猴不仅可以通过交配活动的强度，还可以通过交配活动的时间来维持更高的繁殖成功率。
