An annual algal diversity of Lakhna, Etawah, Uttar Pradesh, India

Abstract

The nature of an ecosystem can be easily assumed by the presence of planktonic diversity, as they have a major role in oxygen amelioration, binding and removal of toxic substances from water body. The present enumeration deals with the annual algal diversity from the Lakhna town of Etawah, Uttar Pradesh. During this one year period, total fifty-four species of Algae recorded viz. Achnanthes minutissima, Amphora ovalis, Anabaena oscillarioides, A. oryzae, Ankistrodesmus falcatus, Aphanocapsa littoralis, Aphanothece microscopica, Arthrospira sp., Calothrix gloeocola, Chlorella vulgaris, Chlorococcum humicola, Chroococcus minor, C. minutes, Cladophora glomerata, Closterium venus, Coelosphaerium kuetzingianum, Cyclotella meneghiniana, Cylindrospermum minutissimum, Euglena minuta, Fragilaria crotonensis, Gloeocapsa magma, Gloeotrichia pisum, Gomphonema parvulum, Hydrodictyon reticulatum, Lyngbya contorta, L. epiphytica, L. majuscula, Merismopedia glauca, M. tenuissima, Microcystis aeruginosa, M. flos-aquae, M. robusta, Mougeotia calcarea, Navicula ambigua, N. brebissonii, N. lata, Nostoc commune, N. punctiforme, Oscillatoria formosa, O. subuliformis, O. princeps, Pediastrum boryanum, Phormidium ambiguum, P. fragile, P. lucidum, Rivularia aquatica, Scenedesmus bijuga, S. obliquus, Spirogyra affinis, S. submaxima, Spirulina gigantea, S. major, Ulothrix zonata, Zygnema collinsianum. This information can be used as baseline data and may be further used to assess any change in algal diversity of Gangetic plain after a sufficient gap to understand the impact of changing climate on it.
