113 rhesus monkeys, representing 4 age classes, 3 matrilines, and immigrant adult males in a 161-member Cayo Santiago-derived troop living in a 2-acre enclosure, were sampled for levels of plasma ACTH and cortisol during a period of capture and brief cage confinement for routine veterinary examination. ACTH levels showed significant decreases over initially… (More)
The food ingestion patterns of the rhesus monkeys (Macaca mulatta) of Group L on Cayo Santiago were quantitatively recorded during two months which coincided with the annual breeding season. Three methods of sampling were used concurrently: interval scan sampling, group location mapping and focal animal observation. These data generated time budgets and… (More)
We evaluated the effects of decreasing spatial density and changing substrate availability on activity, social spacing, and substrate use in a well-established, social group of 12 squirrel monkeys (Saimiri sciureus sciureus). Using instantaneous scan samples, we recorded the specific activity, distance to nearest neighbor, and substrate type for each animal… (More)
Using data from the first community-based, epidemiological survey of Puerto Rico, this paper examines the current prevalence of use of spiritist healers by Puerto Ricans, the role of spiritism in the provision of mental health services, and the association between spiritism and psychiatric disorders and symptoms. Those who visit spiritists were found to be… (More)
The facial expressions of captive, group-living squirrel monkeys are described. Elements of facial expressions, the occurrence of these expressions and accompanying vocalizations are detailed. The range of facial expressions recorded for this species is similar to that previously reported for other simian primates.
Appendix A). In late November 1995 the ODS began to function as a small unit within the Office of the Director, NIH to address a list of items that were part of the DSHEA legislation. While the tasks specified for the new office by DSHEA were numerous, the interpretation of how these tasks were to be accomplished was left to the ODS. As first director of… (More)
A semi-natural habitat that was designed to house a social group of squirrel monkeys (Saimiri sciureus sciureus) at Goucher College, in Maryland is described. The design could be readily adapted for use with other small primate species.
