Comparison on the cell abundance of benthic dinoflagellates in macrophytes and water column collected from open coastal waters and semi-enclosed lagoon = Perbandingan kelimpahan sel dinoflagelat bentos pada makrofit dan turus air yang diambil dari pesisir terbuka dan teluk semi tertutup
Benthic dinoflagellates are known to occur in the water column. The reason they can be found in different parts of the ecosystem is not clear.

| Summary: | Benthic dinoflagellates are known to occur in the water column. The reason they can be found in different parts of the ecosystem is not clear. This study aims to determine the species and the cell abundance of benthic dinoflagellates in the water column and macrophytes collected from two different locations i.e. semi-enclosed lagoon and open coastal waters. The physico-chemical parameters (temperature, salinity, pH, dissolved oxygen) and nutrients (nitrate and phosphate) were determined. Results showed that in the lagoon, the most abundant dinoflagellate species on the macrophytes was also the most abundant dinoflagellate species in the water column. The species that dominated the water column and marophytes in the lagoon was Bysmatrum caponii. In the coastal area the trend was not clear. Coolia dominated the macrophytes whereas Peridinium quinquecorne dominated the water column. The physico-chemical parameters determined were similar at both sites except for nutrients. Results show that type of substrates and different geomorphology effects benthic dinoflagellates cell abundance in the macrophytes and water column.
Kehadiran dinoflagelat bentos di dalam turus air sememangnya diketahui. Sebab kehadiran organisma ini di dalam
bahagian ekosistem yang berbeza tidak diketahui. Tujuan kajian ini ialah untuk mengenal pasti spesies dan kelimpahan
sel dinoflagelat bentos di dalam turus air dan makrofit di dua lokasi berbeza iaitu di teluk separa tertutup dan di kawasan
pesisir yang terbuka. Parameter fizikal-kimia (suhu, kemasinan, pH, oksigen terlarut) dan nutrien (nitrat dan fosfat)
ditentukan. Keputusan menunjukkan di teluk, spesies yang banyak ditemui pada makrofit juga dijumpai banyak di dalam
turus air. Spesies yang mendominasi makrofit dan turus air di teluk ialah Bysmatrum caponii. Namun, di kawasan pesisir,
trendnya tidak jelas. Coolia didapati mendominasi makrofit tetapi Peridinium quinquecorne mendominasi turus air.
Bacaan parameter fiziko-kimia di kedua-dua kawasan adalah sama kecuali nutrien. Keputusan menunjukkan bahawa
jenis subtrak dan geomofologi yang berbeza mempengaruhi kelimpahan spesies yang hadir dalam makrofit dan turus air. |
