The locomotor behaviors of Cayo Santiago rhesus monkeys (Macaca mulatta) were studied in order to determine qualitatively some of the similarities and differences in movement patterns between free-ranging and captive primates. Super-8mm cinefilms of locomotor sequences by all age groups were analyzed frame-by-frame. Cayo Santiago macaques use locomotor behaviors on the ground, large-diametered branches, and vines that correspond to captive monkey locomotion on comparable supports (floors, suspended poles, ropes). Cayo Santiago macaques differ from captive monkeys, however, in that most infants begin to walk using the diagonal-sequence pattern, swimming is common, and infants and juveniles practice a variety of locomotor behaviors among the small-diametered tree branches. Therefore, the Cayo Santiago facility provides 1) insights into the full repertoire of infant and juvenile locomotor behaviors that are essential for studies of motor development and its neural control, and 2) models for designing small-branch supports for captive colonies.
为了定性地确定自由放养和圈养灵长类动物运动模式的一些异同，对圣地亚哥岛恒河猴（猕猴）的运动行为进行了研究。对所有年龄组运动序列的超8毫米电影胶片进行逐帧分析。圣地亚哥岛猕猴在地面、大直径树枝和藤蔓上使用的运动行为，与圈养猴子在类似支撑物（地板、悬挂杆、绳索）上的运动行为相对应。然而，圣地亚哥岛猕猴与圈养猴子的不同之处在于，大多数婴儿开始使用对角序列模式行走，游泳很常见，婴儿和幼猴在小直径树枝间练习各种运动行为。因此，圣地亚哥岛的设施提供了：1）对婴儿和幼猴完整运动行为库的深入了解，这对运动发育及其神经控制的研究至关重要；2）为圈养群体设计小树枝支撑物的模型。
