对31个有机污染程度不同的高山水池的中性水进行了定性和定量的分析。富营养化程度较高的池塘以植鞭藻和纤毛虫为主，富营养化程度较低的池塘以藻类为主。光自养的Heloneuston从浮游生物向表面膜的光依赖迁移导致了中性藻类的强烈抑制。没有发现特别适应中性生物模型的纤毛虫。对9个种的形态、纤毛、银线系统和生态进行了研究。发生频率较高的下丘脑症进行了研究。描述了一新种(Kreyella Minuta)、一新属(Pseudochilodonopsis)和一新科(Kreyelliidae)。讨论了天然池塘表层膜和富营养化养殖中纤毛虫的生态问题。
The qualitative and quantitative composition of the neuston of 31 alpine pools with different degrees of organic pollution was investigated. Phytoflagellata and Ciliophora dominated in highly eutrophic pools, Phycomycetes in less eutrophic ones. The light-dependent migration of the photoautotrophic heloneuston from the plankton to the surface film caused a strong depression of the neustonic Phycomycetes. Ciliates specially adapted to a neustonic model of life were not found. The morphology, infraciliature, silverline system and ecology of 9 spp. occurring more frequently in the hyponeuston were studied. A new species (Kreyella minuta ), a new genus (PSEUDOCHILODONOPSIS ) and a new family (KREYELLIDAE) are described. Some problems dealing with the ecology of ciliates in the surface films of natural pools and of enrichment cultures are discussed.
