| 1 | Natural phytoplankton communities in Pichavaram mangroves Phytoplankton community structure characteristics such as species composition, diversity, richness, evenness and dominance index were studied for 2 years in the Pichavaram mangroves (Tamil Nadu, India). Pennate species such as Nitzschia closterium, Pleurosigma spp., Thalassionema nitzschioides and Thalassiothrix frauenfeldii dominated the population. Diversity, richness and evenness experienced decreasing trend from outer-edge of mangroves towards interior, while dominance index showed opposite trend Source: Mani, P. Indian J. Mar.

| 2 | Phytoplankton in Pichavaram mangroves, east coast of India Marked seasonal cycle with premonsoon and summer peaks were observed. Monsoon season showed low population density. Surface area and plasma volume of phytoplankton population revealed the importance of cell-size characteristics in quantitative analyses. Thirtyone species were indentified as bloom formers, with Rhizosolenia alata f. gracillima attaining a maximum bloom concentration of 2881 x 10 super(7) mu m super(2).1/1 Source: Mani, P. Indian J. Mar. Sci.. 23(1); 1994; 22-26. 0867.
