摘要
本文是对15具不同年龄组的藏酋猴长骨的形态功能学研究,并与猕猴对比的结果。从统计学处理和比较分析看,藏酋猴虽与猕猴有相似之处,但仍有差别存在。藏酋猴具有较长的躯干骨,相对较短的前后肢和桡骨,较高的肢间指数(94.7)和低的臂指数(94.1)。在发育过程中,其肢骨、体重和躯干骨的增长速率均大于猕猴,且前后肢增长率相近。而猕猴后肢的增长明显大于前肢,具相对较短的前肢。由此看来,藏酋猴更适应于地栖生活。
This paper carries on the comparative study on the g(?)swth and functional morphology of limb bones in M. thibelana and M. mulatta. The analysis of the long boner, and skeletal allomctry were bascd on the research of 15 skeletons (5(?)(?) 10♀♀) of different ages. M. thibetana is the special species of China. Compared to M. mulatta, the different characters between them are as. follows: 1. The allometry of limb bone and body weight is not the same at different ages in M. thibetana. The growth of hindlimb is not negative allometry at any stages, but, gradually from positive allometry changes into negative ones with the increasing of body size.
2. In M. thibetana, the ratio of some indices-body weight, fore-and hind-limbs, increasee faster than that of M, mulatta, especially the trunk.
3. M. thibetana posses the relative longer trunk and characterizes by the shorter fore-and hind-limbs.
4. In M. thibetana, the relative shorter length of radius and fore-and hind-limbs, high intermembral index, lower brachial index, are considered as more adaptive to the life on the ground.
