Weight and 34 morphological measurements were obtained from 103 vervet monkeys living either in the wild or in captive colonies derived from the wild populations on the island of St. Kitts in the Eastern Caribbean. All measures were taken during the same week, eliminating bias that might result from changing seasonal environmental conditions. Vervets on St. Kitts are all descended from a small number of individuals brought to the island approximately 400 years ago from West Africa, thus eliminating bias that might result from subspecific size differences. We conducted a principal components analysis (PCA) and compared individual traits between captive and wild adult animals. Morphological measures such as body, arm, and leg length did not differ significantly between animals living in the wild and animals in captivity. Weight and measures indicating condition-including body mass index (BMI), chest, thigh, and upper arm girth were all higher for animals living in captivity. More consistent available food is probably the cause of differences in measures reflecting condition.
我们从103只生活在野外或来自东加勒比海圣基茨岛野生种群的圈养群体中的绿猴身上获取了体重和34项形态学测量数据。所有测量均在同一周内进行，消除了因季节性环境条件变化可能导致的偏差。圣基茨岛上的绿猴均为约400年前从西非带到该岛的少数个体的后代，从而消除了因亚种大小差异可能导致的偏差。我们进行了主成分分析（PCA），并比较了圈养和野生成年动物之间的个体特征。生活在野外的动物和圈养动物在身体、手臂和腿部长度等形态学测量上没有显著差异。圈养动物的体重和反映身体状况的测量指标，包括体重指数（BMI）、胸围、大腿围和上臂围，都更高。食物供应更稳定可能是反映身体状况的测量指标存在差异的原因。
