Several metric and categorical variables were used to assess tail carriage in 717 photographs of 54 yellow baboons (Papio cynocephalus) of known identity, sex, dominance rank, and estimated or known age. Analyses of these data demonstrated that age was the primary factor, influencing tail carriage of baboons not engaged in social interaction. Specifically, the proximal segment of the tail was carried increasingly close to the vertical with increasing age; other changes in tail angles and segment curvature were also correlated with age. There was no relationship between dominance rank and neutral tail carriage in adult male or female baboons, nor was the neutral tail carriage of the first-ranking male or female either distinctive or characteristic. The morphological basis of ontogenetic changes in neutral tail carriage in baboons is also discussed.
我们使用了几个计量和分类变量，对54只已知身份、性别、优势等级以及估计年龄或已知年龄的黄狒狒（Papio cynocephalus）的717张照片中的尾巴姿势进行了评估。对这些数据的分析表明，年龄是影响未参与社交互动的狒狒尾巴姿势的主要因素。具体而言，随着年龄的增长，尾巴近端越来越接近垂直；尾巴角度和节段曲率的其他变化也与年龄相关。在成年雄性或雌性狒狒中，优势等级与中性尾巴姿势之间没有关系，最高等级的雄性或雌性的中性尾巴姿势也没有独特之处或特征。我们还讨论了狒狒中性尾巴姿势个体发育变化的形态学基础。
