Abstract

The present study documents the discovery of the first European population of Colpodidium caudatum (Ciliophora, Colpodidiidae) in a water drain in a school playground in Manzanares (Ciudad Real, Spain). This species has been documented on every continent except Antarctica and Europe, until now. The ciliate was isolated from wet run-off soil collected from the water drain and was grown in semi-permanent cultures in the laboratory. The infraciliature of the ciliate was revealed using silver carbonate impregnation and cell measurements were taken from living and silver-impregnated specimens. A comparative analysis of published data from various populations of C. caudatum across the globe showed high intraspecific morphological variability in this species. To differentiate between species within the Colpodidium genus, a dichotomous key is presented. This investigation shows that C. caudatum is a ciliate that is found all over the world and is particularly associated with terrestrial habitats that are periodically flooded.

欧洲首次记录尾足蝗(纤毛蝗科，尾足蝗科)

本研究记录了在西班牙曼萨纳雷斯(Ciudad Real, Spain)一所学校操场的排水沟中发现的欧洲第一个尾足貂(Ciliophora，貂科)种群。到目前为止，除了南极洲和欧洲，每个大陆都有这种物种的记录。纤毛虫是从排水处收集的湿径流土壤中分离出来的，并在实验室中进行半永久培养。用碳酸银浸渍法揭示了纤毛虫的基础结构，并对活的和浸渍银的标本进行了细胞测量。对全球不同种群的已发表数据的比较分析表明，该物种具有很高的种内形态变异性。为了区分属内的种，提出了一种二分法。这项调查表明，C. caudatum是一种遍布世界各地的纤毛虫，特别是与周期性洪水泛滥的陆地栖息地有关。

期刊介绍： Protist is the international forum for reporting substantial and novel findings in any area of research on protists. The criteria for acceptance of manuscripts are scientific excellence, significance, and interest for a broad readership. Suitable subject areas include: molecular, cell and developmental biology, biochemistry, systematics and phylogeny, and ecology of protists. Both autotrophic and heterotrophic protists as well as parasites are covered. The journal publishes original papers, short historical perspectives and includes a news and views section.
