Thezoogeographical analysis of the mechanism of biodiversity in vertebrates from Indochinese and Sundaic Region

实地调查在泰国、越南、老挝、马来西亚、台湾和其他亚洲国家进行。收集了基因组样本、骨骼和皮肤，为将来的清单做准备。线粒体DNA正在测序，核型正在从肺组织中进行检查。采集骨骼和器官进行形态观察，制作哺乳动物和鸟类的皮肤标本以及爬行动物和两栖动物的腌制标本进行外部形态观察。我们还收集了树鼠、鼠鹿、松鼠、鼹鼠和地鼠的形态数据，并用这些数据来阐明种群之间的地理变异，并讨论了适应策略。对松鼠和鼠鹿的咀嚼肌进行了比较，以描述生态适应与咀嚼肌结构之间的关系。对穿山甲的消化器官和生殖器官也进行了形态检查。对从东南亚到日本的种群中与鼠属关系密切的物种进行了形态上的比较。这使我们能够描述来自日本东京岛上的新物种--Tokudaia tokunoshimensis。我们还对英国、法国和美国的自然历史博物馆的脊椎动物标本进行了比较形态研究。

The field surveys were undertaken in Thailand, Vietnam, Laos, Malaysia, Taiwan and the other Asian countries. The genome samples, skeletons and skins were collected to prepare the inventory in the future. Mitochondrial DNAs are being sequenced, and the karyotypes are being examined from the lung tissues. We collected the skeletons and organs for morphological investigations, and preared the skin specimens of mammals and birds and the pickled specimens of reptiles and amphibians to examine the external morphology. We also collected the morphological data of tree shrews, mouse deer, squirrels, moles and shrews, and the data were used to clarify the geographical variation among populations and discuss on the adaptational strategy. The mastication muscles were compared among species of the squirrels and mouse deer to describe the relationships between ecological adaptation and the architecture of the masticatory muscles. The digestive and genital organs were morphologically examined also in the pangolins. The species closely-related to the genus Rattus were morphologically compared among the populations from Southeast Asia to Japan. It enabled us to describe the new species, Tokudaia tokunoshimensis, from Tokynoshima Island of Japan. We also carried out the comparative morphological studies of the specimens of the vertebrates in natural history museums in England, France and USA.
