Cyanobacteria-Some reports from various habitats of Ranchi (Jharkhand) India

In the present study an attempt has been made on cyanobacteria diversity in various habitats such as epiphytic, lithophyte, epizoic, arboreal etc. in and around Ranchi. In a regular survey of various habitats in different localities of Ranchi District, a total of 34 species of 19 genera were identified. The recorded taxa were unicellular, colonial, trichomatous or filamentous, heterocystous and nonhetrocystous. The identified genera are Merismopedia, Synechococcus, Arthrospira, Spirulina, Oscillatoria, Phormidium, Microcoleus, Lyngbya, Nostoc, Anabaena, Cylindrospermum, Aulosira, Nodularia, Scytonema, Tolypothrix, Gloeotrichia, Rivularia, Calothrix, Nostochopsis. Among the above the most dominated genus is Oscillatoria followed by Lyngbya. All these forms are being reported for the first time from Ranchi (Jharkhand).
