选择长白山区哈泥、金川、圆池和赤池4个典型泥炭藓沼泽作为研究地点,在系统采样基础上调查了有壳变形虫的种类组成特征。75个样品共记录到有壳变形虫33种。这些种类均为国外研究中的常见种类,其中优势种类有苔藓鳞盖虫(Assulina muscorum)、表壳圆壳虫(Cyclopyxis arcelloidestype)、蛹壳虫/三足虫(Croythion-Trinematype)、巧茄壳虫(Hyalosphenia eleglans)、结节鳞壳虫(Euglypha tuberculatatype)、网匣壳虫(Centropyxiscassistype)、染色梨壳虫(Nebela tincta)、泥炭藓截口虫(Heleopera sphagni)。特别是凤蝶茄壳虫(H.papilio)为国内新纪录,它是泥炭藓沼泽的典型种类之一。其他研究中常见的Amphitrema flavum在本研究中未发现。 Four typical peat moss swamps in Ha mud, Jinchuan, Yuanchi and Akchi of Changbai Mountain were chosen as the study sites. Based on systematic sampling, the species composition characteristics of the shelled amoeba were investigated. Thirty-three species of shelled amoeba were recorded in 75 samples. These species are common species in foreign studies, of which the dominant species are Assulina muscorum, Cyclopyxis arcelloidestype, Croythion-Trinematype, Hyalosphenia eleglans, Euglypha tuberculatatype, Centropyxis cassistype, Nebela tincta, Heleopera sphagni. In particular, H.papilio is a new record in China. It is one of the typical species of peat moss swamp. Amphitrema flavum common in other studies was not found in this study.
