摘要

浮游植物,也被称为微藻,是一种微小的光合生物,通常存在于水生环境中。虽然它们被认为是水生生态系统最重要的初级生产者和生物指标,但在巴里沙尔市没有发现关于这些微小生物的报道。为此,本研究选取了北京市10个淡水水库进行浮游植物群落调查,确定了4门7纲18目24科49属110个分类群。从种类数量上看,该区绿藻类分布较为丰富(45个类群),其次为裸藻、绿藻和蓝藻。Euglenaceae仅占本报告总种数的三分之一。在所有站点中,2号站点记录的类群数量最多,9项生物多样性指数中,2号站点和9号站点表现较好。所有记录的分类群以前都被来自孟加拉国的不同作者提到过。

First report on phytoplankton communities of Barishal City, Bangladesh
Phytoplanktons, also called microalgae, are microscopic photosynthetic living organisms that generally found in aquatic environments. Although they are considered as the most important primary producers and bioindicators of aquatic ecosystems, there was no previous report found for Barishal City about these tiny organisms. Consequently, the present study selected 10 freshwater reservoirs from the city to investigate phytoplankton communities and listed 110 taxa under 4 phyla, 7 classes, 18 orders, 24 families and 49 genera. The distribution of Chlorophytes was abundant relatively in terms of species number (45 taxa) followed by Euglenophytes, Chlorophytes and Cyanophytes in this area. Only Euglenaceae possessed one-third of the total species of this report. Among all stations, the highest number of taxa was recorded from station 2 and according to nine biodiversity indices, the station 2 and 9 showed comparatively good results. All of the recorded taxa were previously mentioned by different authors from Bangladesh.
