短尾猴与猕猴肩胛骨的比较研究

COMPARATIVE STUDY OF SCAPULA BETWEEN RHESUS MONKEY AND STUMP-TAILED MACAQUE

对短尾猴(Macaca arctoides)和猕猴(Macaca mulatta)肩胛骨的比较呀究结果表明,由于肩胛骨相对长和肩胛盂-肱骨关节具有很大种间差异,故其运动行为出现某些不同;与猕猴相比,短尾猴更适于地上的四足型运动。所测变量的绝对值表明,短尾猴的肩胛骨较猕猴的大,而异速生长分析表明,猕猴的肩胛骨比短尾猴的更伸向尾侧。各变量的种间差异顺序为:肩胛骨腋缘长>肩胛盂颅侧端至下角长>肩胛骨宽>肩峰突至下角长>肩胛冈长。

Sympatric species, rhesus monkey, Macaca mulatta and stump-tailed macaque, Macace arctoides captured from the wild of western Yunnan of China, show quan titative differences in their use of locomotor patterns during dialy activities. Stumptailed macaque moves primarily terrestrial quadruped. In contrast, rhesus monkey, based on their relative longer caudal scapula, more developed glenoid cavity and greater humerus head, spends more time to move in the tree. Comparison of the length of the glenoid cavity, length of the vertebral border, distance between the cranial tip of the glenoid and the inferior angle, length of the spine, greater and lesser heads of the humerus, and distance between the tip of the acromion and the inferior angle show numerious statistically significant differences between the two species. The results coming from PCA represent that the sequence of the discriminators are: length of the axillary border>distance between cranial tip of the glenoid and the inferior angle>length of the vertebral border or width of the scapula>distance between the tip of the acromion and the inferior angle>length of the spine.
