Some green algae of Ajodhya hills and forest area of Baghmundi (Purulia district, West Bengal)

Fresh water resources are depleting at a fast rate throughout the world affecting diverse aquatic flora and fauna. Algal responds to adverse changes in habitat which is reflected by their morphotaxonomical deformation occurrences of pollution tolerant taxa changed habitat. Based on findings more than five decades, it has been established that such labeled as bioindicator because tolerance. Taking into account, these attributes; systematic enumeration phytoplanktons all dams Ajodhya hills viz. Upper dam, Lower Marvel Lake, Kestobazar lake Murguma dam was carried out. During investigations morphotaxonomy green algal forest area altogether 15 algae were studied. These belong Volvocales, Chlorococcales Zygnematales. come under genera Eudorina, Gonium, Pandorina (Volvocales), Hydrodictyon, Pediastrum, Scenedesmus (Chlorococcales), Spirogyra, Zygnema, (Zygnematales). Out members Zygnematales found be abundant reflecting optimum nutrient atmospheric condition supporting growth. The collections samples made periodically (during 2020 2022) characteristic features studied identification done based standard literatures. However, part affected anthropogenic activity. population showed abundance quality particular organic physicochemical analysis taken up during studies.
