  • Occurrence of a rare desmid Tetmemorus laevis Ralfs ex Ralfs from Yumthang Valley, northern Sikkim with a note on the genus in India
    Debjyoti Das, Jay Mal, Jai Prakash Keshri
    Journal of Threatened Taxa, 2025
    The rare desmid genus Tetmemorus Ralfs ex Ralfs with a single species T. laevis Ralfs ex Ralfs is reported for the first time from the Yumthang Valley of northern Sikkim. This genus is characterized by apical incision apart from the lateral median constriction. Only five species have been reported from different parts of India. This is the first record of the specimen from eastern Himalaya as well as northern part of India. Occurrence of the other species of the genus in India has also been discussed.
  • Rare desmid genus Bourrellyodesmus Compère (Chlorophyceae: Desmidiales: Desmidiaceae) in India with description of a new species (Bourrellyodesmus indicus Das & Keshri sp. nov.) from eastern Himalaya, India
    Debjyoti Das, Jai Prakash Keshri
    Journal of Threatened Taxa, 2023
    During systematic investigations on the algal diversity of eastern Himalaya, the authors recorded a rare desmid genus Bourrellyodesmus Compère for the first time from the Indian subcontinent. After detailed comparative study of the existing species of the genus a new species Bourrellyodesmus indicus has been proposed. A taxonomic note on the existing species of the genus has also been given.
  • A New Species of Actinotaenium (Desmidiaceae, Desmidiales) from Eastern Himalayas, India, with a Note on Its Reproduction

  • Diversity of phytoplankton in some domestic wastewater-fed urban fish pond ecosystems of the Chota Nagpur Plateau in Bankura, India

    Applied Water Science, 2018
    The present limnological investigation is conducted to study the relationship between phytoplankton abundance and five important physicochemical factors in urban wastewater-fed seven fish ponds of Chota Nagpur Plateau area. A total number of 43 phytoplankton taxa representing four classes, namely Cyanophyceae (7), Chlorophyceae (29), Bacillariophyceae (5) and Euglenophyceae (2), are thriving in these ponds which may suggest that different nutrient-rich wastewater supports the diversity and abundance of the phytoplankton. Different values of diversity indices, results of post hoc analysis and rarefaction curve are depicted spatial variations of phytoplankton abundance and physicochemical factors. From the Principal Component Analysis, out of 43 phytoplankton species, 23 important species are extracted. The canonical correspondence analysis presents that most of the phytoplankton species densities are associated with higher values of the physicochemical variables in these ponds. Correspondingly, in the present study, Algal Genus Pollution Index (AGPI) is employed to study the water quality of seven sites. From the AGPI score, it is revealed that Site 4 has probable high organic pollution and Site 2 and Site 3 have moderate organic pollution. Therefore, long-term intensive studies and proper management are necessary to protect these ponds toward eutrophication and degradation, because these ponds not only act as a safeguard of livelihoods but also contribute significantly at local level food and water security and economic prosperity.
