Seasonal changes and horizontal distribution of phytoplankton in Lake Takkobu, Kushiro wetland [Japan]
We investigated the seasonal changes and horizontal distribution of phytoplankton taxa in Lake Takkobu, Hokkaido. A clear seasonal succession appeared in this lake, with the unicellular alga of Chrysophyceae dominant in April, Anabaena smithii in early summer, Pandorina morum in late August, and Cyc...

| description | We investigated the seasonal changes and horizontal distribution of phytoplankton taxa in Lake Takkobu, Hokkaido. A clear seasonal succession appeared in this lake, with the unicellular alga of Chrysophyceae dominant in April, Anabaena smithii in early summer, Pandorina morum in late August, and Cyclotella spp, in autumn. Such a species transition seemed to be caused by changes in the amounts of soluble reactive nitrogen or in water perturbation due to heavy rain. Several species of cyanobacteria were distributed in the northern area, while some flagellates of Chrysophyceae and Chlorophyceae were distributed in the south. Canonical correspondence analysis (CCA) showed that pH and the abundance of chlorophyll a, alkalinity, and dissolved iron and Mgsup(2+) accounted for a statistically significant amount of the variation in the assemblage composition of phytoplankton. It was suggested that the species-specific availability of HCO3sup(-) would correspond to the occurrence of phytoplankton species in Lake Takkobu. |
