| Abstract: | Number of polychaete species identified from Vellar and Uppanar estuaries were 52 and 14 species respectively. Diversity indices were high in Vellar estuary (H’log2-4.264±0.21, d-5.782±0.65, J-0.964±0.008, Lambda'–0.02±0.004 and sPhi+-1906±264.99) and low in Uppanar estuary (H’log2-0.941±0.27, d-1.130±0.42, J-0.418±0.05, Lambda'– 0.70±0.07 and sPhi+ 433±102.74). While the BI (AMBI–1.03±0.19) and M-AMBI (M-AMBI-0.90±0.06) values of Vellar estuary corresponded to the undisturbed nature and high/good estuarine ecological quality respectively, the above values in Uppanar showed the polluted (AMBI–4.47±0.14) and poor/bad status (M-AMBI-0.22±0.04) of estuarine ecological quality. Recently introduced tools such as AMBI & M-AMBI have clearly brought out the impaired health of Uppanar estuary and healthy nature of Vellar estuary. |
