Abstract
The species diversity of soil ciliates in scenic spots and Historic Sites of Maijishan was studied by observation in vivo, fixation and staining. One hundred and fifteen species of soil ciliates were identified, including eleven unnamed species and twenty-six new records of soil ciliates in China, belonging to three classes, twelve orders, forty-one families and fifty-five genera. There were forty-seven, forty-six, forty-four, thirty-three and twenty-six species respectively distributed in Jiezi Wenquan, Quxi Jingqu, Maijishan Shikuqu, Shimenshan Jingqu and Xianrenai Jingqu, and Halteria grandinella, Histriculus similis, Colpoda inflata, C. cucullus, C. fastigata, Tetrahymena rostrata, Spathidium procerum and Spathidium muscicola were widely distributed species. Of which, Prostomatida and Hypotrichida were dominant groups, Colpodida and Scuticociliatida subdominant groups and Pleurostomatida, Suctorida and Oligotrichida incidental groups in the soil ciliate community. The species diversity of soil ciliates in the Scenic Spots and Historic Sites of Maijishan was quite dissimilar to that in other areas of China according to the reported results of relevant studies. This study showed that there were abundant species and a large number of endemic and rare species of soil ciliates in the Scenic Spots and Historic Sites of Maijishan, and their community was complex and unique. The species composition of soil and aquatic ciliate communities in the Scenic Spots and Historic Sites of Maijishan were quite dissimilar, indicating that the soil and aquatic ciliate community belonged to two independent communities.
