Abstract


Algal flora of Jagadishpur reservoir, Kapilvastu district has been studied. The Jagadishpur reservoir, with an area of 225 ha, was declared a Ramsar site in 2003, in recognition of the fact that it supports vulnerable, endangered and critically endangered species as well as threatened ecological communities (MFSC, 2014). The Jagadishpur reservoir and its surrounding area are rich in biodiversity. Epiphytic algae were collected from ten different sites of the wetland, three times during the two month of interval in 2015. The first collection period was falled between the ending of summer and begning of the winter seasons and the second and third collection periods were falled in winter and summer seasons, respectively. A total of 124 algae ( Conjugatophyceae 48%, Chlorophyceae 16%, Cyanophyceae 15%, Bacillariophyceae 8%, Trebouxiophyceae 7%, Dinophyceae 2%, Euglenophyceae 2%, Chrysophyceae and Glaucophyceae 1%) belonging to 9 classes, 22 orders, 36 families and 58 genera were reported. Among them 57 alga are new record for the country. Monthly variation of algal genera was observed. Common genera found in all three collection were Anabeana, Ankistrodesmus, Aphanocapsa, Chroococcus, Closterium, Coelastrum, Cosmerium, Cymbella, Desmidium, Euastrum, Eunotia, Glaucocystis, Gloeotaenium, Merismopedia, Navicula, Oscillatoria, Pediastrum, Scenedesmus, Staurastrum, Triplastrum and Woronichinia. Highest number of algae genera was observed in second and third collection (41 genera) than in first collection (33 genera).
