Timing of births and reproductive success in rhesus monkey social groups.
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.
