Abstract
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.
