     The development of a stable supply of squirrel monkeys and methods to optimize reproduction in captivity are important issues in aging research. These animals, which are frequently used animal models, were once plentiful and available at modest cost. This is no longer the case. The Center for Neotropical Primate Research and Resources (CNPRR) was established, in part to fulfill that need. The CNPRR has been collecting life history data on a captive colony of squirrel monkeys and owl monkeys since 1980 and 2002 respectively, using a relational database to track morbidity, mortality, and reproductive outcomes. These data provide the opportunity to generate demographic statistics, including age specific survivorship, mortality, and fertility over a 20-year period for a set of squirrel monkeys with known birth dates. These demographic statistics were used to construct a model that predicts the future structure and size of the subject population using stochastic (i.e., non-deterministic) mathematical techniques. Tests of the model indicated that four input parameters had the most influence on the outcome: adult female mortality, the annual number of live births, adult male mortality, and the neonatal mortality. This information provides an effective tool in managing primate populations to ensure the future of primate breeding resources. Supported by NIH grant P40-RR001254.
