Biodiversity of Mollusca in Dalmaj Marsh, Southern Marshland, Al-Diwaniya City, Iraq

Abstract

Abstract One of nature’s most valuable resources, biodiversity plays a critical role in meeting many of human requirements and protecting from environmental extremism conditions. Mollusca benthic invertebrates are important biota in aquatic ecosystems and need further investigation. The current study highlights some species recorded in Al-Delmage Marsh in Iraq. The current study points out six species of Mollusca. These species are Melanoides tuberculate, Physa acuta, Viviparus bengalensis, Lymnaea radix, Corbicula fluminalis and Corbicula fluminea. Ecological indices reveal decrease in the values of Shannon (H’), Evenness (E), Margalef (R). This result reflects the ecological disturbance that the world faces over time and Iraq is the fifth country in this regard.
