Description
<p> We focus on the phytoplankton biovolume because phytoplankton affects lake water quality at Lake Kasumigaura, Japan. We analyzed the measurement data of cell biovolumes by Ibaraki Kasumigaura Environmental Science Center from FY 2011 to FY 2018, then we listed the phytoplankton cell biovolumes about 162 taxa. Moreover, we multiply cell numbers by cell biovolumes on the respective taxa basis and then sum up them to calculated total biovolumes at 2 research points. Calculated total biovolumes were significantly positively correlated with total biovolume of the previous research at the 2 research points. This result suggested that our list of phytoplankton cell biovolumes have an availability to calculate total biovolume at Lake Kasumigaura. Thus, it could explain clearly the influence of phytoplankton change on lake water quality and ecosystem.</p>
