Popis: Seasonal variations of planktonic ciliates, with reference to environmental variables, and the relationship between ciliates and their prey were examined for one year in a shallow and eutrophic Korean stream. Large-sized ciliates (>50 μm), such as Hypotrichia sp., Phascolodon vorticella, and Codonella cratera co-dominated with solitary phytoplankton like Stephanodiscus sp. and Cryptomonas ovata in winter and spring. Particularly, the abundance of Phascolodon vorticella was correlated with the abundance of Stephanodiscus sp. (r=0.85, p 0.318), which are similar in structure but different in size. Small-sized ciliates (
