Spatio-temporal Variability of Dinoflagellates in Different Salinity Regimes in the Coast of Rakhine

Abstract

Regarding the spatial and seasonal variations of dinoflagellates in different salinities regimes, Prorocentrum rostratum showed strongly correlated with high salinity (≥ 29ppt.) but P. micans indicated a negative correlation with salinity. In Dinophysoids, Dinophysis caudata showed wide salinity tolerance than other species in the group. D. miles, Ornithocercus magnificus, O. steinii and O. thumii showed a strong correlation with salinity. In Gonyaulacoids, Ceratium furca, C. fusus, C. horridum, C. trichoceros, C. tripos, Gonyaulax polygramma, G. spinifera, and Pyrophacus magnificus showed a strong correlation with salinity. In Peridinoids, Protoperidinium depressum, P. oblongum, P. oceanicum, P. pyreforme, and Podolampus palmipes showed a strong correlation with salinity. In Gymnodinoid and Noctilucoid, Gyrodinium estuariale and N. scintillans showed a strong correlation with salinity.
