| 摘 要： | 用活体观察和蛋白银染色法对甘肃博峪河自然保护区11个采样点的土壤纤毛虫群落特征进行了研究.共鉴定到76种纤毛虫,隶属于3纲10目29科42属.广布种为陆生拟裸口虫(Pseudoholophrya terricola)、僧帽肾形虫(Colpoda cucullus)、齿脊拟肾形虫(Paracolpoda steini)、膨胀肾形虫(Colpoda inflata)、土壤肾形虫(Colpodaedaphoni)、有肋薄咽虫(Leptopharynx costatus)、刚毛胃纤虫(Homalogastra setosa)、近亲殖口虫(Gonostomumaffine)、苔藓游仆虫(Euplotes muscicola).下毛目为该保护区土壤纤毛虫群落中的优势类群,肾形目和前口目为次优势类群,管口目和寡毛目属罕见类群.研究区C/P系数为0.615,Jaccard相似性系数在0.184～0.532之间.结果分析表明,博峪河自然保护区的生境适宜于土壤纤毛虫的生长与繁殖,各样点土壤纤毛虫物种分布有明显差异,且与各样点小生境密切相关,物种数的差异和较低的Jaccard相似性系数显示出土壤纤毛虫群落分布的异质性具有区块特征.

| Abstract: | The composition of soil ciliate community at 11 sampling sites of Boyuhe Nature Reserve of Gansu Province is studied using live observation and protargol-staining.A total of 76 ciliate species belonging to 3 classes,10 orders,29 families and 42 genera is identified,including 6 soil endemic species and 21 species with strong degree of soil autochthonism.Pseudoholophrya terricola,Colpoda cucullus,Paracolpoda steini,Colpoda inflata,Colpoda edaphoni,Leptopharynx costatus,Homalogastra setosa,Gonostomum affine,an... |
