“…In this study, six taxa of Scenedesmus were identified, reported previously by Rai and Paudel (2019) for same reservoir. Also the high number of species of genus Cosmarium noted in this study was similar to the results of Rai and Paudel (2019) , Godar and Rai (2018) and Rai and Rai (2018) for Jagadishpur reservoir.…”

The study of the importance of physicochemical parameters of water for algal growth and development in Jagdishpur Reservoir was carried out in the present research. Occurrence of algal species and values of water quality parameters also indicate the ecological nature and the present status of the reservoir. Water samples were collected from Jagdishpur Reservoir in Kapilvastu District (Nepal), in two seasons (wet and dry). The following physicochemical parameters of water were analyzed: temperature, pH, dissolved oxygen, alkalinity, concentration of nitrates and phosphates, free CO2, hardness, conductivity, total dissolved solids. The values of free CO2, hardness, phosphate, temperature, and dissolved oxygen were high in wet season while alkalinity, nitrate, conductivity and total dissolved solid were high in dry season. Altogether 81 algal species belonging to 53 genera and 6 classes were recorded. Higher number of algal species was recorded in the dry season rather than in the wet season. The highest number of species was noted among Chlorophyceae, followed by Cyanobacteria > Bacillariophyceae > Euglenophyceae > Crysophyceae and Dinophyceae. Cosmarium had the highest number of species (13) among all genera. During the wet season, Cosmarium, Calothrix and Phormidium were the genera with the highest number of species while Bulbochaete, Trachelomonas and Gomphonema were genera with the lowest number of species. During the dry season, Cymbella, Cosmarium and Rhopalodia were genera with highest number of species while Euglena, Gloeotrichia and Trachelomonas were genera with lowest number of species. Algal diversity was positively correlated with the increase of alkalinity, conductivity and TDS, while negatively correlated with free CO2, hardness, concerntration of phosphates and nitrates, DO, pH and temperature. Shannon–Weiner diversity index value was higher during the dry season than in the wet season.

G reen algae are one of the most diverse groups of algae, with at least 7000 species (Nelson and Garcia-Pichel, 2021). Green algae are characterized by several distinct features including filaments, colonies, branched, motile, non-motile, and bladelike thallus (Leliaert et al., 2012). Chloroplast contained chlorophyll a, b and accessory pigments including carotenes and xanthophylls which are surrounded by double membrane with thylakoid arranged in lamellae. Pyrenoid are present and embedded in the chloroplast and surrounded by starch, the primary reserve carbohydrate (Forjan et al., 2015). Green algae have variations in their morphology ranging from microscopic flagellated unicells to complex macroscopic thalli with varying degrees of morphological differentiation. They are a paraphyletic group from a taxonomic standpoint since they have a common ancestor with plants and have Abstract | The current study was carried out to isolate, identify and characterized fresh water green algae species from ecologically diverse habitats of Tehsil Gujar Khan, District Rawalpindi. A microscopic image data was used to identify algal species. A total of 30 species were recorded that belonged to 4 orders, 11 families, and 14 genera. Clamydomonas reinardtii, Acutodesmus obliquus and Cosmarium isthmocondrum are new record from Pakistan. Among identified taxa, Scenedesmus was the dominant genus with 8 species and their contribution was 26.6%. The 2 nd most dominant genus was Cosmarium with 6 species and their contribution was 20%. The other genera Chlorococcum, Ankistrodesmus, Coelastrum, and Closterium were (6.6%). Some genera represented only one (3.3%) species that were Chlamydomonas, Eudorina, Tetraspora, Chlorella, Westella, Pediastrum, Acutodesmus, and Stigeoclonium. Hence, the current study reveals that Gujar Khan, District Rawalpindi is a rich source of green algae and an ideal place for their cultivation.
