The researchers studied the phytoplankton community in Wuliangsuhai Lake in China during the spring of 2012. They found a total of 96 species belonging to 59 genera and 7 phyla, with chlorophyta being the most dominant. The most common species were Gomphosphaeria lacustris, Chroococcus, Oocystis, Scenedesmus quadri-cauda, Chlorella vulgaris, Dictyosphaerium pulchellum, and Cyclotella meneghiniana. The average density of phytoplankton was 8.895×10^7 cell· L-1. The lake was found to be eutrophicated, with Cyanophyta, Chlorophyta, and Bacillariophyta dominating the community. The phytoplankton community was classified into different types based on their distribution in the lake.
