Birth sex ratios and maternal social rank in a captive colony of rhesus monkeys (Macaca mulatta)
Data from a 35-year study of rhesus macaques (Macaca mulatta) at Madingley, Cambridge, were used to investigate sex ratio biases associated with maternal rank. Data were available from two colonies, the Old colony (1960–81) and New colony (1982–93). Overall, top-ranking mothers gave birth to 30.9% sons, while non-top mothers gave birth to 58.4% sons. Among non-top mothers, middle- and bottom-ranking ones had 59.0 and 55.0% sons, respectively. Top…

Prior experience of risk and individual differences in enterprise shown by rhesus monkey infants in the second half of their first year
How rhesus monkey mothers and infants keep in touch when infants are at risk from social companions
Maternal rejection and infant play in rhesus monkey infants
In five-minute records in which they were rejected by their mothers, passive preventions of nipple access, 11- to 15-week-old group-living rhesus monkey infants (Macaca mulatta) initiated fewer playful conctacts with others relative to the other kinds of social contact they initiated, while their overall rates of initiating social contacts may not have been reduced. Whether acts of maternal rejection are costly and distressing to the infant may d…

Effects of early experience on the behaviour of yearling rhesus monkeys (Macaca mulatta) in the presence of a strange object
