摘要

微藻在维持地球上的生命方面起着关键作用。它们既是食物链的基础，也是主要的氧气生产者。微藻对水生生态系统有益，是水体污染的良好指标。本研究试图探索并对Peechi大坝上发现的藻类多样性进行分类分析，该大坝位于喀拉拉邦Thrissur区Karuvannur河的一条支流Manali河上，位于经度76°22′，纬度10°31′。Karuvannur河是Thrissur地区的主要淡水来源之一，流经Thrissur著名的Kole土地。该研究在2017年6月至2018年5月的一年时间内进行。研究期间共鉴定出浮游植物48种，隶属于10个分类纲31属。这10种植物分别属于绿藻科和青藻科，其次是硅藻科(9种)、裸藻科(8种)、蓝藻科(5种)、黄藻科(2种)、Trebouxiophyceae(1种)、Coscinodiscophyceae(1种)、中藻科(1种)和藻科(1种)。ex Ralfs和Tetraplektron torsum (Turner) deusenko - scegoleva是喀拉拉邦的新成员。

Study on Freshwater Algal Biodiversity in Peechi Dam of Thrissur District, Kerala, India

Microalgae have a key role in maintaining life on Earth. They comprise both the base of the food chain and act as major oxygen producers. Microalgae are also beneficial to aquatic ecosystems and make an excellent indicator of water pollution. The present study is an attempt to explore and take taxanomic account of the algal diversity found at the Peechi Dam, which lies across Manali River, a tributary of the Karuvannur River, Thrissur District, Kerala, that lies at 76°22'E longitude and 10°31'N latitude. Karuvannur River is one of the major freshwater sources of the Thrissur district, which flows through the famous Kole lands of Thrissur. The study was carried out over a period of one year, from June 2017 to May 2018. During the period of study, 48 species of phytoplankton were identified which come under 31 genera belonging to ten taxonomic classes. Out of these 10 species each belong to Chlorophyceae and Zygnematophyceae followed by Bacillariophyceae (9 species), Euglenophyceae (8), Cyanophyceae (5), Xanthophyceae (2), Trebouxiophyceae (1), Coscinodiscophyceae (1), Mediophyceae (1) and Dinophyceae (1). Two of the species Xanthidium octocorne Ehr. ex Ralfs and Tetraplektron torsum (Turner) Dedusenko-Scegoleva are new to Kerala.

期刊介绍： The algae are heterogeneous assemblage of phytosynthetic organisms, one of the most vast and diverse groups of ancient photoautotrophic pro- and eukaryotic organisms (about 30 000 known species). They are micro- and macroscopic, unicellular, colonial, or multicellular, mobile and immobile, attached and free-living. Algae are widespread in water and soil habitats, at different geographic latitudes, and on all continents. They occur in waters with different degrees of salinity, trophicity, organic matter, and hydrogen ions, and at various temperatures. They include planktonic, periphytonic and benthic organisms. Algae are unique model organisms in evolutionary biology and also are used in various genetic, physiological, biochemical, cytological, and other investigations.
