Study of Dinoflagellate Species in the Waters of Bayur Gulf and Bungus Gulf, Padang City, West Sumatera, Indonesia: Diversity and Morphological Variations
Keywords:Diversity, Morphological Variations, Dinoflagellate, Bayur Gulf and Bungus Gulf
Dinoflagellates are important phytoplankton as primary producers in the waters. Dinoflagellates are found in all types of waters both fresh, salty, brackish, ice, wetlands and other moist places. Dinoflagellates are the second largest phytoplankton after diatom and can undergo morphological changes in response the environmental changes. This research has been conducted on March until June 2009, in the waters of Bayur gulf and Bungus gulf, Padang city, West Sumatera, Indonesia, using survey method and direct collection in the field. Sampling stations are set purposively as many as 11 stations with consideration of land use. Results showed that there were 30 species of dinoflagellates in the waters of Bayur Gulf and Bungus Gulf, 26 species were found in the waters of Bayur Gulf and 25 species were found in the waters of Bungus Gulf. Attendance frequency of 11 species were found was 100%, five of them experience morphological variation, namely Ceratium carriense, C. horridum, C. macroceros, C. trichoceros and C. tripos.
