To assess the effects of environmental changes on phytoplankton community structure in a mangrove ecosystem, phytoplankton distribution in Matang mangrove, Malaysia was examined. Phytoplankton and water samples, and in situ environmental parameters from three estuaries with differing levels of disturbance were examined monthly for one year. Two species, Cyclotella choctawhatcheeana and Skeletonema costatum, were dominant in the least disturbed and moderately disturbed areas, respectively. Skeletonema costatum was also the most dominant in the most disturbed area. Significant differences in phytoplankton density and biodiversity between the least and most disturbed areas were also observed. Principle component 1 (salinity, conductivity, total solids/water transparency and nitrogenous compounds) and PC2 (dissolved oxygen, pH and temperature) explained 60.4% of the total variance. This study illustrated that changes in phytoplankton community structure in Matang mangrove estuaries were significantly correlated with environmental parameters which were in turn influenced by ecosystem disturbance levels as well as seasonal changes.

红树林的扰动导致马来西亚马塘红树林的河口浮游植物群落结构发生变化。

为了评估环境变化对红树林生态系统中浮游植物群落结构的影响，研究了马来西亚马当红树林中浮游植物的分布。一年中每月检查一次浮游植物和水样，以及来自三个河口的不同干扰水平的原位环境参数。最小扰动和中度扰动区域主要有两个物种：Cyclotella choctawhatcheeana和Skeletonema costatum。在最受干扰的地区，肋骨骨架也是最主要的。在最小和最大受干扰地区之间也观察到了浮游植物密度和生物多样性的显着差异。主要成分1（盐度，电导率，总固体/水透明度和含氮化合物）和PC2（溶解氧，pH和温度）解释了总差异的60.4％。这项研究表明，马当红树林河口浮游植物群落结构的变化与环境参数显着相关，而环境参数反过来又受到生态系统干扰水平和季节变化的影响。
