Description
Summary:Peridinium palatinum belongs to the group of algal species of which we have only a few taxonomical and ecological data, although in some running and standing waters of Hungary it can be found in large numbers. The aim of our study, accomplished from 1990 to 1996, was revealing the occurrence of this species. Our results suggest that the occurrence of P. palatinum has been influenced by two factors: water temperature and the organic matter concentration of water. Comparing eleven types of waters in which it either appeared or not, it could be established that P. palatinum occurs in waters that exceed a relatively high level of organic matter concentration. Concerning water temperature P. palatinum is a typically winter early spring organism, because the temperature are important in the excystment and the developing of vegetative cells. Consequently, its occurrence can well indicate relatively high concentrations of organic nutrients during the winter season in Hungarian freshwaters.
