Speciation of the monkeys of genus Macaca.

本研究通过野外观察，从不同的研究领域阐明了猕猴属的进化：1.苏拉威西猕猴包括7种，通过形态学特征，如体测量、X射线照相、通过对7条a链的氨基酸序列分析，揭示了它们的系统发育关系，并根据它们的亲缘关系推测了它们之间的多个遗传事件。2.对西苏门答腊野生猪尾猕猴的社会生态学研究表明，多雌性的配置与扭曲的成年性别比例对女性和他们类似的社会组织，以其他猕猴。与印度尼西亚的食猴相比，安加尔的食猴明显小型化。寄生虫学试验表明，该岛食蟹猴个体平均杂合度（h）相对高于印度尼西亚和菲律宾。

The present field studies are made to elucidate the evolution of the genus Macaca by verious research fields.1.The Sulawesi macaques consist of 7 species.Morphological characteristic such as somatometry,radiography,color analysis of skin color and dermatogrlyphics revealed their characteristics.Phylogenic retionships among these species were analyzed by the complete amino acid sequences of seven a chains.The multiple genetic events were postulated by their distant relationships and their distribution.2.Socio-ecological study of the wild pig-tailed macaque in West Sumatra revealed the unit groups consisting mult-male,Multi-female configuration with distoring adult sex ratio towards females and their similar social organization to those of other macaques.3.The inspection of the crab-eating monkey in Angaur elucidated the significant miniaturization as compared to those in Indonesia.Parasitological test revealed that only streptopharagus spp.was detected as helminth.Mean heterozygosity per individual(h)of crab-eating monkeys of this island was relatively higher than that in Indonesia and the Phylippines.
