Diversity of scleractinian corals in the world ocean demonstrated by the species belong to the family Acroporidae. Andaman and Nicobar Islands represent a total of 158 species of acroporids which is equivalent to 57.04% of the global diversity. The numerical data on Shannon-Weaver diversity (H'), Simpson's density (D) and Pielou's evenness (J) indices showed a healthy state of acroporids in these islands. South Andaman region can be emphasized as the best reef environment area followed by North and Middle Andaman region and Nicobar region as all the indices such as H' (5.82), D (0.98) and J (0.94) show maximized value.

Abstract


Diversity of scleractinian corals in the world ocean demonstrated by the species belong to the family Acroporidae. Andaman and Nicobar Islands represent a total of 158 species of acroporids which is equivalent to 57.04% of the global diversity. The numerical data on Shannon-Weaver diversity (H'), Simpson's density (D) and Pielou's evenness (J) indices showed a healthy state of acroporids in these islands. South Andaman region can be emphasized as the best reef environment area followed by North and Middle Andaman region and Nicobar region as all the indices such as H' (5.82), D (0.98) and J (0.94) show maximized value.
