Species Diversity of Macrophytes of the New Calabar River, Niger Delta, Nigeria


Author(s): Dienye HE

Abstract: Survey of macrophytes from the New Calabar River was conducted to quantify the species diversity. The macrophytes studies were conducted between December and May 2014 along the edge and in the middle of the River. Ten families of macrophyte were recorded representing 12 species. Cyperaceae had the highest species with three species while the remaining had one specie each. The result of this study showed that Rhynchospora corymbosa had the highest abundance (richness), followed by C.difformis while the species lowest abundance (richness) was Eichhornia crassipes, Nymphaea lotus was the lowest in evenness (distribution) followed by Aneilema beniniense and Platostoma africana having the same level of distribution. Aspilia africana had the highest evenness. The diversity indices indicated that Rhynchospora corymbosa had the highest taxa value 65, Shannon Weinner 4.01, Simpsons 0.98 and Margalef 7.60 while Eichhornia crassipes recorded the lowest taxa of 17, Shannon Weinner had 2.72, Simpsons 0.92 and Margalef 2.30 respectively for macrophytes. The biotic indices of Margalef’s species richness, Shannon - Wiener information function, evenness and Simpson’s Dominance were fairly distributed in the River. This showed that the macrophytes in the study area were stable.
