    The present investigation conveys a unique diversity of cyanobacteria and eukaryotic algae from Atri, Taptapani, Tarabalo and Deulajhari geothermal springs of Odisha, India. The study revealed a floristic account of 48 taxa belonging to 39 cyanoprokaryotes, 5 diatoms, 2 charophytes and 1 each from desmids and euglenoids. One exciting record showed Jaaginema geminatum, as the most dominant cyanobacteria from euthermophilous and mesothermophilous communities. The cyanoprokaryotes, Romeria chlorina, Isocystis messanensis, Trichormus thermalis, Geitlerinema jasorvense and Westiellopsis indica were newly reported from the study area. Interestingly, Isocystis messanensis is newly added to the Indian flora. The physicochemical analysis of the spring water showed high sodium (97.72 mg/L) and calcium (5.5 mg/L) in Deulajhari, whereas high magnesium (0.8 mg/L) in Taptapani. While nitrate and phosphate were high in Deulajhari and Atri hot springs, Tarabalo has the highest sulfate content. While nitrate and phosphate content was high in Deulajhari and Atri hot springs, Tarabalo has the highest sulfate content. The Kruskal-Wallis test was applied to see the differences in the physicochemical parameters of the four geothermal springs, and significant differences were found at the bicarbonate value (HCO3). Temperature variations in four thermal springs suggested the presence of euthermophilic and mesothermophilic species. The pH of the four water bodies was moderately basic. In addition, four geothermal springs were compared in terms of anions and cations using the Piper diagram, and it was determined that they showed Na+-K+-HCO3-properties. Principal Component Analysis (PCA) was performed under the CANOCO software to determine the statistical correlation between species and physicochemical parameters. As a result of the PCA, the total variation was 36.2500; the first axis explained 36.84% of the variance. The distribution pattern of all the species found in the four thermal springs has also been studied. A morphotaxonomic study was conducted with the help of microphotographs and line drawings. © 2022 by the authors.

    Taxonomic and Ecological Aspects of Thermophilic Cyanobacteria from Some Geothermal Springs of Jharkhand and Bihar, India
    (Egyptian Academy of Science and Technology, 2023) Basu P.; Satpati G.G.; Öztürk S.; Gupta R.K.
    IN the present research, we have highlighted the taxonomic and ecological aspects of cyanobacteria, identified from some less-explored geothermal springs of Jharkhand and Bihar in India, with respect to water temperature variations and other physicochemical parameters, which is still an understudied topic. In total, twenty six different cyanoprokaryotes were identified. Based on our observations, the Chatra hot spring of Jharkhand area was found to be rich in cyanobacterial diversity where eight different taxa were reported. Among the recorded taxa, Geitlerinema amphibium, Komvophoron cf. schmidlei, K. jovis and Leptolyngbya granulifera are rare cyanobacterial species with a limited geographical distribution inhabiting the Indian springs based on the previous studies and available literature on the hot springs of India. The correlation of the cyanobacterial species identified and water parameters was studied by redundancy analysis (RDA) under CANOCO 5.0. Moreover, sampling stations were added in the RDA analysis. As a result of the RDA, the total variation was 23,83333, and it is seen that the first two axes explain 47.39% of the total variance. RDA analysis results showed that values of pH, sulfate, and sodium ions were the most effective water factors affecting the distribution of the cyanobacterial taxa identified. Though the water temperature is an important factor controlling the distribution of cyanobacterial taxa inhabiting the thermal water habitats, it was not among the most important abiotic drivers according to the RDA analysis in this work. © 2023 National Information and Documentation Center (NIDOC).
