Studies of the Evolution of the Asian Non-human Primates

对亚洲非人类灵长类动物进化进行实地研究的小组由三个小组组成，1）苏拉威西猕猴，2）东加里曼丹猩猩生态学和3）在泰国捕获食蟹猕猴。1）居住在印度尼西亚苏拉威西岛的猕猴包括七个物种，在外部形态特征上表现出明显的差异。我们调查了生活在种间边界地区的猕猴的形态特征，发现杂种仅限于hecki和tonkeana，nigra和nigrescens之间的限制区域。在该地区之外，猕猴在每个物种中都表现出明显的形态特征。在实地研究中，我们收集了宠物猴的血液样本。我们可以把血样放在碎干冰下带回。β-珠蛋白基因的DNA结构分析即将完成。2）1983年，东加里曼达省大面积的低地热带雨林被烧毁。该地区包括猩猩的自然栖息地。红毛猩猩在火灾后经常使用伯克，但沿着第二片森林的繁殖，他们开始使用树叶，茎和水果。3）在泰国9个不同地区共捕获12个类群的278头猕猴。利用采集的血液样本进行的群体遗传学和分子生物学研究表明，泰国北部和南部猕猴之间存在明显的差异。后者与马来亚半岛和大巽他岛关系密切，而前者与它们有明显的区别。形态学研究也显示了类似的差异。

The team carrying out the field studies on the evolution of the Asian non-human primates comprised of three team, 1) The Sulawesi macaques, 2) Ecology of orangutans in East Kalimantan and 3) Capturing works crab-eatiang macaques in Thailand.1) The macaques inhabing the Sulawesi island, Indonesia, comprise seven species and show clealy differences in the external morphological character. We investigated the morphological characteristics of the macaques living in the boundary areas among species and found that hybrids were limited to restricted areas between hecki and tonkeana, and nigra and nigrescens. Outside of the areas, the macaques showed clearly morphological characteristics in each species. In the field studies, we collected blood samples from pet monkeys. We could brought back the blood samples under crashed dry ice. The analyses of DNA structure of psibeta-globin genes will be soon completed.2) The huge area of low land tropical rain forest in East Kalimanta was burned in 1983. The area includes the natural habitats of orangutan. Orangutans used the burk frequently just after the fire but along with the reproduction of the second forest they became to use leaved, stems and fruits. We could clearified the relationship between feeding ecology of orangutans during the reproduction of flora.3) We could capture total 278 heads of crab-eatiang macaque of 12 groups at 9 different areas in Thailand. Population genetical and molcular biological studies using blood samples collected showed the clear differenciation of the macaques between norther parts and southern parts of Thailand. The latter related closely to those of Malayan Peninsula and Great Sunda Isaland but the former showed clear differences from them. Morphological sutdies also showed similar differences.
