abstract:
Ciliates abundance and species composition were analysed in the slightly eutrophic Lake Uściwierz of Łęczyńsko-Włodawskie Lakeland. Samples were taken in the pelagic zone in spring (May), summer (June) and autumn (November) 2002. Ciliates were collected with a 5-litre Bernatowicz sampler, every 1-metre in the deepest place, from the surface to the depth of 5 m. Twenty nine (29) species of ciliates were found in the plankton samplers. The mean abundance of the ciliates was 6 ind. ml-1 and the mean ciliates biomass was 81 μg·l-1. The following species dominated among the ciliates: Peritrichida (Vorticella sp.), Oligotrichida (Halteria gradinella and Strombidium sp.) and Scuticociliatida (Cinetochilum margaritaceum).
