Analysis of six years of birth records (228 potential reproductive years) from 71 female rhesus monkeys, housed in social groups in outdoor compounds, revealed several variables which influenced the reproductive pattern. The timing of conception in this seasonally breeding species was influenced by age, parity, and reproductive outcome the previous year, but not by social rank. In contrast, high social rank did confer an advantage in higher conception and lower infant mortality rates.
对71只雌性恒河猴6年的出生记录（228个潜在繁殖年份）进行分析，这些猴子饲养在户外场地的社会群体中，结果揭示了几个影响繁殖模式的变量。在这个季节性繁殖的物种中，受孕时间受年龄、胎次和上一年的繁殖结果影响，但不受社会等级影响。相比之下，高社会等级确实在更高的受孕率和更低的婴儿死亡率方面具有优势。
