【摘要】 地下啮齿动物由于其独特的栖息环境,在农田、森林和草原生态系统中占有重要的位置。地下啮齿动物繁殖、选择栖息地以及危害环境与其扩散密切相关。扩散是动物扩大分布区域,进行基因交流和促进生物进化的重要机制。研究地下啮齿动物扩散对控制危害和保护生物多样性有着重要意义。但是,地下啮齿动物栖息于地下,对研究扩散增加了难度。本文根据目前国内外已有的部分地下啮齿动物扩散研究,评述了发生扩散的原因,扩散的群体,扩散的时间以及扩散的方式等内容,并展望了新技术和新方法对研究地下啮齿动物扩散的可能性,以期为研究高原鼢鼠扩散提供理论参考和技术借鉴。更多还原

【Abstract】 The subterranean rodents play key roles in the cropland,grassland and forest ecosystems because of their unique habitats. The dispersal of the rodents is closely related to the reproduction,habitat selection,as well as the environment damage. The dispersal is the mechanism of animals that extend distribution,transfer gene and improve evolution.Studying dispersal of the subterranean rodents is very useful for pest control and biodiversity conservation. However,its difficult to study the dispersal of subterranean rodents because they live underground. This paper reviewed the dispersal of the subterranean rodents in term of causes,individual,time and ways based on the completed studies in the world. The new technologies and approaches were also proposed in this paper. The purpose was to provide some references for studying the dispersal of plateau zokor in China.更多还原
