Primary production of phytoplankton in a strongly stratified temperate lake,e of a ‘good’ status. Considering the total amounts of nutrients stored in the hypolimnion, the average potential concentrations in the whole water column could achieve 1885 mg m. of TN and 170 mg m. of TP reflecting hypertrophic conditions and a ‘bad’ status. Improvement of the epilimnetic water qu

Vertical and seasonal dynamics of planktonic ciliates in a strongly stratified hypertrophic lake,dually replaced by scuticociliates and mixotrophic . spp. In the hypolimnion scuticociliates and species known as benthic migrants dominated. In the epilimnion and upper metalimnion in spring large herbivores and in summer small bacterivores were more numerous.
