| Abstract | A study on the diversity of marine phytoplankton at Phra Thong Island, Phangnga Province, Thailand was carried out in January 2016. Phytoplankton was sampled at 12 stations using plankton nets with mesh size of 20 micrometres. A standard bottle was used to collect water samples for vertical distributions study at 13 levels: subsurface, middle and 0.5 metre above the bottom. Sixty-five species were identified by light microscope. Forty-nine diatom, 12 dinoflagellate, 3 cyanophyte, and 1 silicoflagellate species were found. The most diverse dinoflagellate genus was Ceratium. Other diverse diatom genera were Chaetoceros and Rhizosolenia. Phytoplankton density ranged 381,230 cells L-1. Following species were most abundant Guinardia flaccida, Rhizosolenia bergonii, and Bacteriastrum hyalinum. Principal component analysis suggested that the structure of the phytoplankton communities was determined by hydrology and nutrient concentrations. Multivariate analysis revealed that a total dissolved nitrogen and phosphorus concentrations were the major factors controlling phytoplankton abundance. The results of the present study give an improved understanding of the factors that structure the coastal phytoplankton communities at Phra Thong Island. |
