Abundance and Ecological Relationships of Physa acuta in Freshwater Bodies of Chandigarh (U.T), India and its Surrounding Areas.
Journal Title: Advance Research Journal of Multidisciplinary Discoveries - Year 2018, Vol 23, Issue 23
Abstract
Mollusks, the second most abundant animal fauna after arthropods, play an important role in their ecosystem’s rejuvenation and recycling of locked nutrients. Being tolerant species many of these can also be used in biomonitoring and risk assessment studies of aquatic as well as terrestrial ecosystems. However, very little importance has been given to these animals despite of their abundance. The freshwater Indian gastropod fauna, 4.34% of the global freshwater gastropods, has remained neglected in major part of the country. The main focus of malacofauna had been around their taxonomy and their ecology had remained more or less a neglected field. The present investigation has focused on the ecological studies of an invasive species of Physidae (P. acuta) in different types of permanent water bodies in Chandigarh and its nearby areas and according to the results of Linear Regression and Pearson’s Correlation Coefficient certain parameters are positively influencing (Ph, Chloride, and Hardness) and certain negatively (Temp., Alkalinity, TDS and EC) in determining the density of the species in relation to specific parameter. The Dominance Index indicates the species under study has been found in eudominant state at all the sites.
