The lentic ecosystems include pools, ponds, puddles, lakes, wetlands, reservoirs and so on. Algae play a significant role because of their dynamic eco-strategies and their amplitude in terms of diversity in morphological and physiological attributes. The present study was carried out in Sikkarayapuram stone quarries measuring 120 acres of land with...

... The Chlorophyceae was mainly represented by Scenedesmus, Pediastrum, Kirchneriella, Selenastrum, and Tetraedron. A total of 60 species identified in the present study is lesser than the 68 species identified in Sikkarayapuram stone quarries at Chennai [63], 172 species identified in various quarries in Ukraine [53], and 117 species in Bogunsky quarry in Zhitomir at Ukraine [64]. Summarily, the plankton richness of these systems gives a normalcy tag. ...
... Order-wise distribution witnessed the Sphaeropleales dominance condition. More orders with different species were observed in the current study, which is higher than the orders revealed in Sikkarayapuram stone quarries at Chennai [63]. Sphaeropleales order dominant condition in the present observation is in array with Sikkarayapuram stone quarries at Chennai [63] and Bogunsky quarry in Zhitomir Ukraine [64]. ...

Global warming and increasing CO2 play an important role in making terrestrial and aquatic life highly pathetic. Microalgae have many advantages over other methods in bioremediation and carbon sequestration including eco-friendly nature, less space requirement, and sustainable energy production from wastes. The aim of the present investigation is to assess the microalgal diversity, followed by isolation of microalgae from the abandoned urban man-made ecosystem and evaluation of their carbon fixation potential. Samples were collected for a year (October 2021–September 2022). The prominent water quality parameters were estimated. The Statistical Package for Social Sciences, version 26.0, was used to estimate Karl Pearson’s correlation coefficient and one-way analysis of variance. Paleontological Statistics (version 4.03) was used to estimate the diversity indices. Sixty species categorized into 7 classes, 19 orders, and 41 genera were identified. The quantitative spectrum revealed that Bacillariophyceae was the dominant class (231 cells/L) followed by Chlorophyceae (220 cells/L). In carbon sequestration, Scenedesmus vacuolatus (6.50 mg/L/h) performed more efficiently than Arthrospira platensis (1.81 mg/L/h). It is vital to explore the occurrence of microalgae from all possible wet environments, which further can be isolated and employed in various biotechnological applications.

During the studies of algae in the Wayanad district, a notable diversity of desmids observed in the Karapuzha dam, Kerala, India. Karapuzha Dam is 700 to 2061 metres above sea level and is a part of Western Ghats. Thirty‐nine taxa of desmids were identified from Karapuzha Dam of Wayanad district from June 2019 to May 2020. The collection comprises ten genera of 39 desmids, including 24 species of Cosmarium, 5 Staurastrum, 2 Closterium, 2 Euastrum, 1 Gonatozygon, 1 Triplastrum, 1 Penium, 1 Spondylosium, 1 Micrasterias and 1 Arthrodesmus. Among these, Cosmarium regnesi var. montanum is new to India, 8 taxa are new to Kerala and 2 taxa are new to South India. Some rare and high altitude distributed species are found in the study. This desmid diversity relates to the oligotrophic nature of the dam. This paper is a pioneer attempt to document the desmid flora of Karapuzha Dam, Kerala.
