A comparison of the demographic structure and growth of free-ranging and captive groups of rhesus monkeys (Macaca mulatta)

Abstract

Vital statistics are employed to estimate rates of mortality, fetility and growth for a group of about 450 captive rhesus monkeys housed in six separate enclosures at the California Primate Research Center (CPRC). These rates were compared with those previously reported for a free-ranging group of rhesus monkeys. Relative to the free-ranging group, the CPRC monkeys experienced higher fertility below age 5 and lower mortality beyond age 3. These rates are associated with a potential intrinsic rate of increase of about 10%, a rate which is about 50% higher than that for the free-ranging group. Reasons for this marked difference in reproductive success of the two groups are discussed.
