中国滇、川、湘鄂猕猴(Macaca mulatta)肩胛骨的比较研究

本文是中国滇、川、湘鄂猕猴肩胛骨和肩关节形态结构对环境适应性的比较研究结果。多变量分析结果表明,肩胛冈长、肩峰长、关节盂仰角和三角肌止点对猕猴种下分类有重要作用。川西猕猴较大的体重和体型明显不同于湘鄂(华中)和滇南猕猴,表现出更多的地上四足型运动的适应特征。华中和滇南猕猴具有更相似的肩胛骨形态结构,且有更多的树上活动。

THE SCAPULAR COMPARISON OF RHESUS MONKEYS IN SICHUAN, YUNNAN, HUBEI AND HUNAN IN CHINA

This paper carried out the functional comparative study of scapula in Macaca mulatta distributing over Sichun, Yunnan, Hubei and Hunan Provinces in China. The results of multivariate analyses suggested that the lengths of scapular spine and acro-mion,the angle of glenoidalis cavity and the insertion of m. deltoideus on humerus played an important role for distinguishing the subspecies of M. mulatta of China. Sichuan's race which showed more terrestrial quadrupedal activities,is significantly different from other two subspecies. The scapular morphologies of rhesus monkey's race in Yunnan shared some similar features with that of ones in Hunan and Hubei. And both races possess much arboreal locomotions than Sichuan' race. It suggests that their classif icatory position may be most closely and same subspecies as showed by Zhang et al. (1991).
