Biodiversity of the Macroinvertebrates in the Southern Iraqi Marshes, with a special reference to Oligochaeta
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 7, Issue 1
Abstract
Despite the importance of macroinvertebrates in the dynamics of aquatic ecosystems, however, a little work has been conducted on this group in Iraq. The aim of the present paper is to investigate the distribution and diversity of aquatic macroinvertebrates of the Marshes of Al-Swaib, southern Iraq. Invertebrates, occurring in the shallow water zones at two stations in the Al-Swaib Marshes, were sampled at monthly intervals during March 2012 to February 2013, in order to determine the relationship between the aquatic invertebrates (both species number and individual number) and some environmental factors such as water temperature, pH, conductivity, organic matter and texture of the mud at each station. A total of 8325 individuals of invertebrates belonging to 37 taxa was sampled. The most dominant groups were Varia, Oligochaeta and Gastropoda. Varia group comprised about 54% of the total invertebrates, followed by Oligochaeta (34%) and Gastropoda (12%). The Shannon-Weaner diversity index ranged from 0.56 to 1.11.Canonical Correspondence Analysis (CCA) revealed that the temperature and pH were the most important factors affecting some species of macroinvertebrates.
