Investigation of phytoplankton from East China Sea of the Pacific Ocean, offshore Reunion Island of the Indian Ocean, and the French Atlantic coast revealed a species of poorly known armored fusiform dinoflagellate. To clarify this species, morphology and phylogeny based on mitochondrial and nuclear protein gene sequence (Cox1, Cob and Hsp90) concatenated with the SSU, ITS region and LSU rDNA sequences were analysed. Epifluorescence and scanning electron microscopy observations revealed that the...

Margalefidinium polykrikoides, an unarmored dinoflagellate, was suspected to be the causative agent of the harmful algal blooms - associated with massive fish mortalities - that have occurred continually in Lampung Bay, Indonesia, since the first bloom event in October 2012. In this study, after examination of the morphology of putative M. polykrikoides-like cysts sampled in bottom sediments, cyst bed distribution of this harmful species was explored in the inner bay. Sediment samples showed tha...

Acute and severe hypoxia associated with harmful algal bloom has become one of the major causes for the environmental deterioration of coastal areas. Although it is generally thought that a large part of the dissolved oxygen consumption at a bloom site is initiated by heterotrophic bacteria that attack organic matter derived from dead or dying algal cells, precise microbial processes leading to the hypoxia are yet to be examined. Here we show temporal dynamics of extracellular dissolved organic ...

SUMMARY Small subunit (SSU) and large subunit (LSU) rDNA sequences have been commonly used to delineate the taxonomy and biogeography of the planktonic diatom genus Skeletonema, but the genes occur as multiple copies and are therefore not suitable for barcoding purposes. Here, we analyzed phylogenetic relationships of Skeletonema using the mitochondrial-encoded cytochrome c oxidase I gene (cox1), as well as partial LSU rDNA (D1–D3) and SSU rDNA, to identify the factors that define species and to...

Aquaculture of the mudskipper Pseudapocryptes elongatus has expanded rapidly over the past 10 years in the provinces of the Mekong Delta of southern Vietnam. The fish’s capacity for aerial breathing enables its farming in earthen ponds with no aeration or little water exchange. We compared the composition and abundance of algal and bacterial cells, the rates of oxygen consumption by microorganisms, and daily fluctuations in dissolved oxygen (DO) concentration in fish aquaculture ponds, and compa...

Merambong Shoal of the Tebrau Straits is an importantseagrass bed and feeding ground to the marine mammal, Dugongdugon. The area is exposed to greater environmental pressures due tocoastal development in recent years. Phytoplankton composition ofthe Merambong Shoal was assessed in this study based on the samplescollected during the JSPS-Malaysia Joint Expedition in July 2012.A total of 30 genera of micro-phytoplankton were documented, withfive and twenty five genera of dinoflagellates and diatom...

Two new woloszynskioid dinoflagellates, Asulcocephalium miricentonis gen. et sp. nov. and Leiocephalium pseudosanguineum gen. et sp. nov., are described from Japanese freshwater ponds on the basis of bright field and fluorescence light microscopy, scanning and transmission electron microscopy, and molecular phylogeny inferred from rDNA sequences. Asulcocephalium miricentonis has a spherical anterior nucleus and chloroplast with a pyrenoid penetrated by the cytoplasm. This species has 9–12 latitu...
