目的掌握塔里木盆地啮齿动物体外寄生蚤的群落组成和结构。方法根据地理区划和生境类型选择调查点,按样方法捕获啮齿动物,对体外寄生蚤进行单独鉴定,采用群落生态学技术方法,计算各鼠类蚤类群落的组成和结构。结果在塔里木盆地共捕获啮齿动物7种351只,获体外寄生蚤10种683只,构建7个鼠类蚤类群落。结论子午沙鼠体外寄生蚤的蚤指数、丰富度和多样性3项指标均较高,对该地区蚤类群落的构成和稳定起到了积极的作用,长耳跳鼠和三趾跳鼠的蚤类群落结构相似,并与子午沙鼠蚤类群落形成结构上的互补性,对维持塔里木盆地蚤类群落构亦具有重要的作用;群落间的相似性比较分析表明,塔里木盆地的7个鼠类蚤类群落归为跳鼠蚤类群落、家栖或半家栖鼠类蚤类群落和子午沙鼠蚤类群落3个类群。
Objective To understand the composition and structure of parasitized fleas in rodents in the Tarim Basin. Methods The investigation points were selected according to the geographical division and the type of habitat. Rodents were captured by the method of sampling and the parasitic fleas were identified separately. Community composition and structure of the fleas were calculated using the method of community ecology. Results A total of 351 rodents were captured in the Tarim Basin and 683 species of ectoparasites were collected from 10 species of rodents. Seven groups of rodent fleas were constructed. Conclusion The flea index, abundance and diversity of the fleas in the Meriones unguiculatus were high, which had a positive effect on the constitution and stability of the fleas in the area. The fleas Similar structure of the community structure, and Merionesia flea communities to form a structural complementarity, to maintain the fleas in the Tarim Basin structure also plays an important role in the community comparative analysis showed that the seven Tarim Basin The fleas were classified into 3 groups: flea flea community, domestic or semi-domestic flea community and flea community.
