项目摘要

We had the plan of 1996 to put our focus on the study of hybrid baboons between Thelopithecus gelada and Papio hamadryas in the southern highland. However, the changes of political situation made it difficult to conduct the research in the southern regions. Conflicts between different ethnic groups which constitute the new government body have become tense, and the local Oromo (the main nationality [=tribe] in the region) government in the southern regions has become to behave rather independently from the central government. Warnings from terrorists were sent to Embassies of G7 countries which support the present government. As the Embassy of Japan requested us not to stay in the southern regions, we decided not to conduct research in the regions this year.We found hybrid baboons between gelada and hamadryas baboons in a zoo in the suburb of Addis Abeba ; the zoo reared a mixed group of both species in a cage. A few hybrids between the two species were present. We found a female hybri … More d was in a late stage of conception. The hybrid female is fertile. This indicates that the study of hybrid region in wild is important. We collected blood samples from these hybrids ; these samples were prepared as to be used for the analysis of chromosome as well as for that of protein and DNA.The hybrid animals showed hybrid vigor, i.e.the hybrid animals of both sexes were far larger than the counterparts of the parent species. We obtained a male of this human raised hybrid, and took samples of blood, tissues, and the skull. The morphological study of the skull of hybrid vigor will be interesting.Our field study in Ethiopia was changed from the southern highland to the northern highland this year. We collected 26 blood samples at around Desse in the middle part of northern highland, being different from the previously studied Semien population which situates far north in the northern highland.Though Kingdom of Saudi Arabia has been known for the distribution of hamadryas baboons, it seemed almost impossible to enter the country. Research permission was issued for the University of the Air (Housou daigaku). We took this advantage, and shifted our study area of hamadryas baboons from Yemen to Saudi Arabia this year in cooperation with the University of the Air. Though we obtained blood samples of only 3 hamadryas baboons in Saudi, this visit opened a door to the study in Saudi Arabia for the future. The 3 samples are now being analyzed to get some ideas for the understanding of divergence between Ethiopian and Saudi populations of hamadryas baboons.We visited Egypt, and discussed with staff of Cairo Agricultural Museum, coming to the conclusion of cooperation on the study of DNA analysis of mummies of hamadryas baboons.

1996年,我们计划将重点放在南部高地的长臂猿和帕皮欧·哈马德里亚斯之间的杂交狒狒的研究上。然而,政局的变化给南方地区的研究带来了很大的困难。组成新政府机构的不同民族之间的冲突变得紧张,南部地区的地方奥罗莫人(该地区的主要民族)政府已经变得相当独立于中央政府。恐怖分子的警告被发送到支持现任政府的G7国家大使馆。由于日本大使馆要求我们不要停留在南部地区,我们决定今年不再在这些地区进行研究。我们在亚的斯亚贝巴郊区的一家动物园发现了狮头蝠和哈马德里亚斯狒狒之间的杂交狒狒;动物园在笼子里饲养了这两个物种的混合种群。这两个物种之间出现了一些杂交。我们发现了一只雌性Hybri…More d处于受孕的后期阶段。杂交的雌性是有生育能力的。这说明野生杂交种的研究具有重要意义。我们采集了这些杂交动物的血液样本,这些样本被准备用于染色体分析以及蛋白质和DNA的分析。杂交动物显示出杂交活力,即杂交动物无论性别,都远远大于相应的亲本物种。我们获得了这一人类饲养的杂交种的雄性,并采集了血液、组织和头骨的样本。对杂交种活力头骨的形态研究将是有趣的。我们在埃塞俄比亚的实地研究今年从南部高地改为北部高地。我们在北部高地中部的Desse附近采集了26个血液样本,与之前研究的塞米安种群不同,塞米安种群位于北部高地的最北端。尽管沙特阿拉伯王国一直以Hamadryas狒狒的分布而闻名,但似乎几乎不可能进入该国。向空气大学(后代课)颁发了研究许可。我们利用了这一优势,今年与航空大学合作,将我们对Hamadryas狒狒的研究区域从也门转移到了沙特阿拉伯。虽然我们在沙特只获得了3只哈马德里亚狒狒的血液样本,但这次访问为未来在沙特进行研究打开了一扇门。目前正在对这3个样本进行分析,以了解埃塞俄比亚和沙特种群之间的差异。我们访问了埃及,并与开罗农业博物馆的工作人员进行了讨论,得出了合作研究哈马德里亚斯巴布亚木乃伊DNA分析的结论。较少
