Annotation
The zooplankton community was surveyed along the longitudinal axis of Rimov Reservoir (Czech Republic) on seven occasions during the vegetative season of 1996. The dimictic Rimov Reservoir has a pronounced trophic gradient along its axis. In nearly all samples, rotifers were dominant by numbers and formed on average 60 to 95 of the total zooplankton (including copepod nauplii). There was a consistent pattern of increasing relative abundance of rotifers in the upper regions of the reservoir compared with the downstream parts. There was a greater similarity between two adjacent sites in the proportions of crustacean species than in rotifer species. This is partially due to the greater species diversity of rotifers than that of crustaceans. The site specific zooplankton patchiness seems to be reduced as there was no site dependence if average data on zooplankton composition from downstream lacustrine sites were compared.
