Seasonal Variations on Species Composition and Abundance of Marine Dinoflagellates in the Response of Environmental Parameters at Rakhine, Mon and Northern Tanintharyi Waters

Abstract

A total of 69 taxa of dinoflagellates at Rakhine coastal waters, 8 taxa at Mon coastal waters, and 29 taxa at northern Tanintharyi coastal waters were recorded in the present study. Regarding the percentage composition of dinoflagellates, Gonyaulacoid and Peridinoid were noted as the most abundant groups in dinoflagellates. A wide range of salinity fluctuations was noticed in the present study due to the effects of the monsoon cycle in the Indian Ocean. The maximum salinity, 34‰ was recorded in pre-monsoon months whereas the minimum value, 14‰ was detected in monsoon season. The highest pH value, 9.0 was observed in monsoon months. The concentrations of PO4-P, NH3-N, and NO3-N were normally high during pre-monsoon months. The cell abundance of dinoflagellates at all stations was high during pre-monsoon months indicated that a mesotrophic environment favor species richness and dense.

Measurement of Coordinated and Coupled Development and Evaluation of Sustainable Development for Marine Economic-Ecological Complex System

“…As a result, the coastal regions in China discharge more and more pollutants, which seriously threat the marine ecoenvironment. erefore, it is of practical significance to measure the coordinated and coupled development (CCD) and evaluate the sustainable development of the marine economic-ecological complex system (MEECS) [5][6][7][8][9][10]. e coordinated development of marine economy and ecoenvironment is critical to the national strategies for ocean and regional coordinated development [11][12][13][14].…”
