| Article Name : | | | SEASONALITY OF INVERTEBRATE FAUNA INHABITING LOWER SHIWALIK STREAM, PHILODINAVUS PARADOXUS- THE FIRST REPORT | | Author Name : | | | Shiwali Gupta, Sarbjeet Kour and Harjeet Kaur | | Publisher : | | | Ashok Yakkaldevi | | Article Series No. : | | | GRT-5078 | | Article URL : | |  | Author Profile View PDF In browser | | Abstract : | | | The present contribution encompasses on few zooplankton groups and physicochemical parameters as ecological indicator for identifying the ecological quality of Devika stream at Udhampur district, J&K. The seasonal variation of both these components were analysed for a period of one year (July, 2013– June, 2014). Fifteen physico-chemical parameters were analysed and a remarkable seasonal variation was recorded in them during the study period. Regading zooplankton, a total of 36 genera were recorded, out of which Protozoa was represented by 14 genera, Copepoda by 12 genera, Rotifera by 6 genera and Cladocera by 4 genera. Among these zooplankton, Rotifera showed its presence throughout the study period and the recorded data clearly showed well-marked seasonal fluctuation in zooplankton population with the presence of new rotifer sp. viz. Philodinavus paradoxus. The various kinds of indices such as Shannon-Wiener index, Simpson index, Margalef’s index and Menhinick’s index were also analysed. | | Keywords : | | - Consumer Durable Goods Industry,
