“…The reduction in the proportion of the nannoplankton in Oak Mere since 1966, owing to the development of a dominant netplankton, is in accordance with Pavoni's (1963) conclusion that nannoplankton tends to dominate lakes at the extremes of the trophic scale, whether oligotrophic or 'hypertrophic'. Oak Mere has thus become 'eutrophic' in her scheme of classification.…”

The pelagic Rotifers of the mesotrophic lake of Sempach (Switzerland) were investigated qualitatively and quantitatively from 1969 to 1971. The Rotifer reproduction rate was highest from spring until early summer, with peaks of 0.86 million individuals below 1 dm 2 in 1969, and 0.92 in 1970. During summer stratification, production was comparatively low. During both years Keratella cocMearis made up on an average of 50%0 of the total number of Rotifers. Keratella cocMearis, K. quadrata and Kellicottia longispina reproductive rates were calculated, using the egg ratio method of Edmondson. The highest yearly rates of the three species were noted in spring at a depth of 0 to 5 m. From spring until early summer in 1970, 88% of the biomass of tke first large phytoplankton peak were nannoplankton, 70% of which consisted of Cryptophyceae and Chrysophyceae from the end of April until the middle of June. During the investigation of the three Brachionidae, inquiries into the food relation of nannoplankton algae showed close relations to these algae groups and more over to ~-algae. In spring the Chrysophyceae Erkenia subaequiciliata seems to be the most important food for the three Rotifer species. IIgHALTSVERZEICHNIS
