项目摘要

Indonesia is attractive to the students of evolution for a number of reasons. It occupies a central part of Asian tropics, which is known to harbor the world's richest and most diverse fauna and flora. Furthermore, it consists of many islands that differ in their size and distance from other islands. The impact of human activity is also very important factor for the process of dispersal and vicariance on evolution in the last several thousands of years. Relations between the human activity in prehistoric life and the distributions of organisms are, however, still unclear.Arthropodal community living in mammal excrements, especially cow dung, is consisted by various diverse taxa; several kinds of beetles, of flies, also several mites nematode, and so on. The community is also showed very diverse biogeographical variations, therefore, many scientists have been engaged taxonomic and ecological works on organisms in excrements. Indonesian wild cow, Banten Bos javanicus, is a restricted distributed animal in where only Java, Bali and Karimantan Islands. The Banten is modified domestic animals, which are distributed wholly Indonesian countries and Islands.This project aims to elucidate pattern and process of biogeography of terrestrial arthropods in Asian tropics, with particular emphasis on insects and mites in mammal excretory substance and carcass. Our methods include (1) field collection of specimens, (2) gathering in-depth biological information of target taxa, and (3) rearing of insect in the laboratory.As a result of this project, we show some of the patterns and process of distribution in tropical organisms, but they are still largely unknown. We published 45 papers, and described, 27 species and 1 subspecies as new to science. We hope our result will greatly contribute to enrich knowledge of this important field of evolutionary biology, especially in the last several thousands of years.

印度尼西亚对进化的学生很有吸引力，原因有很多。它占据了亚洲热带地区的中心部分，众所周知，它拥有世界上最富有，最多样化的动物群和动植物。此外，它由许多岛屿组成，它们的规模和距离其他岛屿的距离有所不同。人类活动的影响也是过去数千年来分散和替代过程进化过程的非常重要的因素。但是，人类活动在史前生活中的活动与生物体的分布之间的关系仍然不清楚。生活在哺乳动物排泄物中的关节座社区，尤其是牛粪，由各种多样的分类单元组成。几种甲虫，苍蝇，还有几种螨虫线虫等等。社区还显示出非常多样化的生物地理变化，因此，许多科学家都从事出口中有机体的分类学和生态作品。印尼野牛，Banten Bos Javanicus，是只有Java，Bali和Karimantan群岛的有限分布动物。该项目旨在阐明亚洲热带地区陆地节肢动物的生物地理学模式和过程，特别强调哺乳动物排泄物和癌症中的昆虫和螨虫。我们的方法包括（1）标本的现场收集，（2）收集目标分类单元的深入生物学信息，以及（3）实验室中昆虫的饲养。由于该项目的结果，我们显示了热带生物体中的一些模式和分布过程，但它们仍然很少知道。我们发表了45篇论文，并将27种和1个亚种描述为科学的新作品。我们希望我们的结果将极大地有助于丰富对进化生物学的重要领域的知识，尤其是在过去的几千年中。
