摘　　要：利用下毛类纤毛原生动物中的贻贝棘尾虫和大尾柱虫为材料,观察了它们在同一小环境中的生活状况,比较了它们单独培养时与混合培养时的分裂速度的变化情况,了解它们的种间竞争的情况.结果表明贻贝棘尾虫与大尾柱虫种间存在竞争.The interspecific competition is one kind of biological phenomena, which has the close relation with the biological evolution, the distribution and so on. In this paper, we using the hypotrich ciliates protozoon＇s Stylonychia mytilus and Umstyla grandis, observed living condition of two species in the identical microenvironment, found out their interspecific competition. The result indicates that the Stylonychia mytilus and Urostyia grandis inter- species exist competition.
