Bioluminescent seas caused by blooms of the dinoflagellate Noctiluca scintillans are a famous scenic attraction in the Matsu archipelago near the Chinese coast in the northern part of the Taiwan Strait. The relationship between the abundance of N. scintillans and various environmental factors was examined in the subtropical coastal waters of these islands from April to December, 2016. N. scintillans disappeared after June 20th, when the sea water temperature exceeded 27°C. A strong inverse correlation between N. scintillans and diatoms in PCA analysis indicated that diatoms suffer high grazing pressure from N. scintillans. N. scintillans appeared most abundantly during the flood season, when diatoms are most abundant. Strong inverse correlations between N. scintillans and the wind speed and wind direction in PCA further point to the effect of wind on the accumulation of cells.
夜光藻水华引发的生物发光现象是中国台湾海峡北部马祖列岛附近亚热带近岸水域的著名景观。2016 年 4 月至 12 月，研究人员对这些岛屿亚热带近岸水域中夜光藻的丰度与各种环境因素的关系进行了调查。5 月 20 日之后，当海水温度超过 27°C 时，夜光藻便消失了。主成分分析（PCA）中的夜光藻与硅藻呈强烈负相关，表明硅藻受到夜光藻的强烈摄食压力。夜光藻在硅藻最丰富的丰水期最为丰富。PCA 中夜光藻与风速和风向的强烈负相关进一步表明了风对细胞积累的影响。
