We examined the question of whether the occurrence of menopause in rhesus macaque (Macaca mulatta) females approximates that found in women from a life history standpoint. We used data from two provisioned free-ranging populations of rhesus macaques to estimate the probability that a juvenile female not only will survive to the potentially postmenopausal(More)
The reproductive performance of 760 free-ranging female rhesus monkeys (Macaca mulatta), 168 of whom were 20 years of age and older at the time observations were begun, was assessed. The monkeys were resident on Raccoon Key or Key Lois, two islands located in the Florida Keys, USA. During 1992 and 1993, live birth rates generally declined with age among the(More)
This paper provides an analysis of infant body weights obtained from a sample of 38 rhesus monkey infants (Macaca mulatta) aged 29-165 days, i.e., animals still nutritionally dependent on their mothers. We examine the data on neonatal weights in relation to a number of factors, most notably, the sex of the infants, and the age and adiposity of their(More)
We here examine interindividual variability in reproductive aging in free-ranging female rhesus macaques (Macaca mulatta). Our study site, Raccoon Key, is an island, about 81 hectares in area, situated in the Gulf of Mexico. Our data were collected from 1992 to 1998; the last 7 years a large population of provisioned macaques were resident on the island. We(More)
