“…The dominance of different algal classes in this lake was reported as Bacillariophyceae and Zygnematophyceae (29% each), Chlorophyceae (18%), Cyanophyceae (14%), Euglenophyceae (8%) and Ulvophyceae (2%) (Figure 3B). Jyotsna et al (2015) also observed maximum members of Bacillariophyceae in Karagam Lake, Srikakulam, Andhra Pradesh, India. Similarly, Vyas and Kumar (1968) observed higher Euglenophyceae population in post-monsoon season.…”

Algae can be found in the sea, freshwater and wastewater all around the world. Although the majority is microscopic, some are large. In this study, a total of 44 samples, were collected in two seasons (pre-monsoon and post-monsoon) in the years 2021-2022 from Kingfisher Lake, located in the Bharatpur, Chitwan District. A total of 51 algal species belonging to six classes were recorded. Information on the distribution of algal flora of Kingfisher Lake was collected and the data revealed that the dominant members belong to the classes Bacillariophyceae and Zygnematophyceae, each having 15 species; followed by Chlorophyceae, Cyanophyceae and Euglenophyceae. Similarly, the physico-chemical parameters of water were measured by a digital portable multiparameter (HI98194) in the field. Water temperature was low during post-monsoon season. Electrical conductivity, Total Dissolved Solids (TDS), Oxidation Reduction Potential and Dissolved Oxygen were high in post-monsoon season while the pH of the lake water was alkaline and low pH in post-monsoon season. The number of algal species was found higher in pre-monsoon season than in post-monsoon season. The study showed that the lake is rich in algal species. Presence of the species like Closterium sp. and Oscillatoria sp. indicate that the lake is eutrophicated and polluted. Thus, further investigations were needed.

The present study was to understand the diversity and distribution pattern of microalgae in fresh water system represented by an open artificial pond. A total of 100 species of phytoplanktons were indentified from different groups during March 2014 to February 2015. Among the identified phytoplankton species Cyanophyceae (39%) formed the dominant group, followed by Chlorophyceae (34%) Bacillariophyceae (23%) and Euglenophyceae (4%). The fluctuations in the physico-chemical parameters like pH, temperature, EC, DO, BOD, COD, turbidity, alkalinity, hardness, nitrate, silicate, phosphate and were also been monitored. The result provides a primary documentation of the phytoplankton community and its diversity and basic understanding of hydrological variables in the pond ecosystem.

In the present paper morpho-taxonomic descriptions along with the illustrations of three infraspecific taxa of genus Micrasterias C. Ag. ex Ralfs, analysis of ecological parameters and correlation coefficients between nine limnological parameters as well as the relative abundances of the genus had been described. These three taxa are Micrasterias pinnatifida var. pinnatifida fa. pinnatifida (Kütz.) Ralfs, Micrasterias tropica Nordstedt var. crassa West & West and Micrasterias foliacea var. foliacea Bailey ex Ralfs belonging to the order Zygnematales under the class Chlorophyceae. All these taxa were distributed in ponds (inland water bodies) in Hooghly district, West Bengal, India. The results of analysis of physico-chemical parameters of the ponds water revealed that lower temperature and nutrient status in respect of nitrate-nitrogen (NO3-N): phosphate (PO43-): potassium (K); higher dissolved oxygen (DO) values and, slight alkaline water prompted their occurrences, growth and diversity. The above said infraspecific taxa are new taxonomic reports from West Bengal, India. The taxonomic study explored the present biodiversity of this genus while the ecological study showed a clear picture of ecological conditions and water quality of the studied water bodies.INTERNATIONAL JOURNAL OF ENVIRONMENTVolume-5, Issue-2, March-May 2016 Pages 36-47
