AB -The characteristic periodical changes in the species and communities of phytoplankton in a pond situated in northern Taiwan were studied for three years, from July 1986 to June 1989. the physicochemical factors as well as the amount of zooplankton were taken into account to elucidate the relation of them to the variations in phytoplankton density during the study time is not due to the decline in grazing pressure. The maximum of phytoplankton densities in the pond was developed toward summer. Nevertheless, seasonal succession in phytoplankton communities was not evident. The results from the analysis of water quality and from the indicator species of phytoplankton indicate that this pond was in hypereutrophic state and of the level between beta-and alpha-mesosaprobity. High nutrient concentration in the pond and mild temperature in winter were regarded to be the main reason resulting in the irregularity of the periodical changes in phytoplankton assemblages.
