Abstract:
In this present study, the two unexplored coastal areas such as Olaikuda and Vadakkadu, Rameshwaram, southeast coast of India have been explored for its seaweeds diversity to know the diversity status of these two areas. The two stations were well diversified with three groups of seaweeds such as Chlorophyceae, Phaeophyceae and Rhodophyceae. Totally, 74 species of seaweed were found in two stations among which 28 species belong to Chlorophyceae, 18 species belong to Phaeophyceae and 28 species belong to Rhodophyceae. This survey recorded 37.83% Chlorophyceae and Rhodophyceae, followed by 24.32 % Phaeophyceae. In Olaikuda, total 59 seaweeds were found. Of which, 26 species belong to Chlorophyceae, followed by 22 Rhodophyceae and 11 Phaeophyceae. The seasonal diversity of Olaikuda revealed that species diversity was equal during post monsoon and summer. A total number of 49 seaweeds including 9 Chlorophyceae, 15 Phaeophyceae and 25 Rhodophyceae were recorded at Vadakkadu. The seasonal survey at Vadakkadu showed that post monsoon and summer had the higher seaweed diversity than premonsoon and monsoon. The K-dominance plot, cluster analysis and biodiversity indices were analysed with software PRIMER package and software R statistic version 3.1.4. Package (vegan). It can be concluded that these two stations were well diversified with seaweeds.
