中文摘要: 原尾虫是一类形态独特的低等六足动物,在六足动物和节肢动物起源进化研究中具有重要的意义,然而,原尾虫的系统分类学研究仍然不足。中国原尾虫分类学研究一直领先国际水平,但是古北区原尾虫的分类学研究相对匮乏,这阻碍了我们对原尾虫的起源、演化和地理分布格局等问题的深入研究。本项目拟对中国古北区原尾虫进行系统全面的调查和分类学研究,填补研究空白,完善我国古北区原尾虫的物种多样性的研究;开展DNA条形码研究,建立中国和世界原尾虫DNA条形码数据库,以便解决原尾虫形态学鉴定困难的问题,为将来原尾虫生态学、生理学和发育生物学等研究奠定基础;首次采用分子数据和形态数据相结合的全证据,整合原尾虫的地理分布数据,开展原尾纲系统发育生物地理学研究;采用地理信息系统全面分析原尾纲的地理分布格局,结合地质历史信息和环境因子等信息,深入探讨原尾纲的起源、演化和适应辐射等问题。

英文摘要: Protura is a group of basal Hexapoda with unique morphological characters, which has important role in the study of evolution of Hexapoda and Arthropoda. However, the systematic and taxonomic studies of Protura are still inadequate. Though the taxonomy of Protura in China is better than other countries and lead the international communities, the taxonomy of Protura from Palaearctic regions of China is still insufficient, which impede the studies of origin, evolution, and geographical distribution patterns of Protura. The present project plans to comprehensively investigate the Protura of Chinese Palaearctic region, conduct the taxonomic and systematic study, supplement and improve the species diversity knowledge of Protura in that region. The DNA barcodes database for Chinese and world Protura will be constructed for the first time in order to overcome the difficulties in morphological identification of Protura, so as to lay a foundation for the ecological, physiological and developmental researches of Protura in the future. The phylogeographical studies based on the total evidences combined by molecular and morphological data, as well as geographical information data will be performed. The geographical distribution pattern of the Protura will be analyzed by using geographic information system. By mapping the geologic history information and the environmental factors, the origin, evolution and adaptive radiation of Protura will be explored.
