63-69
Seasonal variation in the numerical abundance of 42 spp of phytoplankters (18 centric, 20 pennate diatoms, 3 dinoflagellates and 1 Trichodesmium) at the mouth of the Vellar Estuary, Tamil Nadu, India has been followed for 3 yr. Quantitative distribution of diatoms follows trimodal annual patterns. Negative correlations exist between diatom density and blooms of dinoflagellates and Trichodesmium. Variations in quantity and settling volume correspond to changes in ambient salinity. Shannon-Wiener indices are linearly related to number of species, phytoplankton density and settling volume. Temporal variations in the community largely depend on the salinity and to a lesser extent on the ambient surface water temperature. The correlation matrix reveals the presence of atleast 5 diverse components in the phytoplankton community. |
