Evolutionary Studies of Small Animals in Asian Tropics

在这个项目中，我们计划在热带亚洲、马来西亚和泰国进行实地研究。1992年，我们在马来半岛西部地区进行了调查：Kaki Bukit、Gunung Jerai、槟榔屿、拉鲁特山、卡梅伦高地、弗雷泽山和云顶高地。在1993年的第二年夏天，我们考察了马来西亚沙捞越的国家公园和野生动物保护区：兰比尔山、古农木鲁、兰扎克-昂蒂茂、古农盖丁和苏门萨姆。在这些调查中，我们收集了昆虫、两栖动物和爬行动物，记录了青蛙和壁虎的声音，并收集了蜥蜴的温度数据。我们还研究了褐飞虱和金龟子幼虫的自然历史。两栖动物和爬行动物的冰冻组织被保存下来，并被带回日本进行未来的基因分析。并对核型分析结果进行了分析。将天牛幼虫和天牛幼虫带回日本，在实验室进行自然历史研究，并对青蛙的声音数据进行分析，并与中国、日本等地区的青蛙声音数据进行比较。对兰科菊属的研究发表了。在马来半岛的山区发现了一些未被描述的半叶虎属壁虎物种。这些发现将在与从博物馆借来的同类物种进行比较后发表。在婆罗洲和马来半岛发现了几种新发现的绿头金龟属和金龟子甲属。收集的标本保存在京都大学，部分标本被送回各国的同行。至于在泰国的研究，由于8月中旬获得国家研究委员会的研究许可，我们于1993年9月才在Kachanaburi进行了初步调查。我们参观了泰国科学技术研究所，并对保存的标本进行了检查。

In this project we planed field researches in tropical Asia, Malaysia and Thailand. In 1992, we made surveys in the western regions of the Malay Peninsula : Kaki Bukit, Gunung Jerai, Penang Island, Larut Hill, Cameron Highlands, Fraser's Hill, and Genting Highland. In the next summer, 1993, we surveyed national parks and wildlife sanctuaries of Sarawak, Malaysia : Lambir Hill, Gunung Mulu, Lanjak-Engtimau, Gunung Gading, and Sumunsam. In these surveys, we made collections of insects, amphibians and reptiles, recorded voices of frogs and geckos, and collected temperature data for lizards. We also studied natural histories of lucanid and passalid beetle larvae. Frozen tissues of amphibians and reptiles were kept and brought back to Japan for future genetic analyses. The karyological studies were also processed and analyzed. The alive insect larvae of lucanid and passalid beetles were brought back to Japan and reared in the laboratory for natural history studies.Frog Voices data have been analyzed and compared with those from other regions, such as China and Japan. The study of the ranid genus Amolops were published. The some undescribed gecko species of the genus Hemiphyllodactylus were discovered in the mountain regions in the Malay Peninsula. These findings will be published after the comparisons with allied species loaned from the museum. Several species of the lucanid and passalid beetles were newly described from Borneo and the Malay Peninsula. The collected specimens were deposited in the Kyoto University and parts of them were returned to our counterpart in each country.As to the researches in Thailand, we made only preliminary survey in Kanchanaburi in September in 1993, since the research permission from National Research Council was received in the middle August. We visited Thailand Institute of Scientific and Technological Research, and examined the deposited specimens.
