During the last two decades, large-scale high biomass algal blooms of the dinoflagellate Prorocentrum donghaiense Lu have occurred frequently in the East China Sea (ECS). The role of increasing nutrient concentrations in driving those blooms is well-established, but the source population that initiates them is poorly understood. We hypothesized that the front of Taiwan Warm Current (TWC) may serve as a ‘seed bank’ that initiates P. donghaiense blooms in the ECS, as the physiochemical conditions… Expand
Harmful Dinoflagellate Prorocentrum donghaiense Lu is Widely Distributed Along the East China Sea and Korean Coastal Area
There have been controversies regarding the taxonomy of Prorocentrum donghaiense, however Zhang et al. (2016) recently developed a probe with a quantitative real-time PCR (qPCR) assay that targetsExpand
Genetic diversity of Prorocentrum donghaiense population during bloom in the East China Sea revealed by microsatellite
Nine microsatellite markers based on transcriptome sequencing uncovered the genetic distinctiveness in P. donghaiense populations between 2014 and 2016 and provide valuable insights into the genetic structure and diversity of P.Donghaiense blooms. Expand
Distribution of Alexandrium pacificum cysts in the area adjacent to the Changjiang River estuary, China.
A low-abundance region of the cysts present in spring is in accordance with the intrusive pathway of the Nearshore Kuroshio Branch Current (NKBC), suggesting that A. pacificum blooms could be regulated by seasonal intrusion of NKBC. Expand
Distribution Patterns of Picosized and Nanosized Phytoplankton Assemblages in the East China Sea and the Yellow Sea: Implications on the Impacts of Kuroshio Intrusion
Kuroshio, the strongest west boundary current of the Pacific Ocean, has significant impacts on the oceanographic conditions and ecological processes of the Pacific-Asian marginal seas throughExpand
A novel method for discriminating Prorocentrum donghaiense from diatom blooms in the East China Sea using MODIS measurements
Abstract The dinoflagellate Prorocentrum donghaiense ( P. donghaiense ) is one of the most common species making up harmful algal blooms in the Yangtze River Estuary and the adjacent area of the EastExpand
Occurrence of HAB / toxic Dinoflagellates species from the coast of Karachi, Pakistan (Northern Arabian Sea)

Kuroshio subsurface water feeds the wintertime Taiwan Warm Current on the inner East China Sea shelf
The Taiwan Warm Current (TWC) has an overwhelming influence on the heat, salt, and nutrients balance on one of the broadest shelf in the world, the East China Sea shelf. In winter, the TWC flows inExpand
Prorocentrum shikokuense Hada and P. donghaiense Lu are junior synonyms of P. obtusidens Schiller, but not of P. dentatum Stein (Prorocentrales, Dinophyceae).
Morphological observations and a phylogeny based on the SSU, ITS region and LSU rDNA sequences revealed that the previously confused species and the studied strains are conspecific and that the morphology of strains identified as P. dentatum in the phylogenetic trees does not coincide with P. obtusidens.

Seasonal shifts in the contributions of the Changjiang River and the Kuroshio Current to nitrate dynamics in the continental shelf of the northern East China Sea based on a nitrate dual isotopic composition approach
The northern East China Sea (ECS) serves as a spawning and nursery ground for many species of fish and squid. To clarify the basis of the food web in the north- ern ECS, we examined the nitrate (NO3)Expand

Interspecies competition for nutrients between Prorocentrum donghaiense Lu and Skeletonema costatum(Grev.) Cleve in mesocosm experiments
Three mesocosm experiments were conducted in the East China Sea during blooms of Prorocentrum donghaiense Lu to examine the role of nutrients in the formation of these harmful algae blooms to show that there was interspecies competition between P.donghaiense and Skeletonema costatum(Grev.) Cleve. Expand
Effects of temperature, salinity and irradiance on the growth of the harmful dinoflagellate Prorocentrum donghaiense Lu.
The effects of water temperature, salinity and irradiance on the growth of this described P. donghaiense Lu species under nutrient-replete laboratory conditions are examined. Expand
Influence of hydrographic conditions on picoplankton distribution in the East China Sea
An investigation was made on picoplankton distributions in relation to physical and chemical conditions in the East China Sea in July 1998, and Prochlorococcus was basically associated with oceanic warm currents, and sudden changes in cell abundance often occurred within a relatively short distance of the currents.

Morphological and genetic study of Prorocentrum donghaiense Lu from the East China Sea, and comparison with some related Prorocentrum species
It is suggested that the high-biomass bloom-forming species in the East China Sea, previously reported as Prorocentrum dentatum Stein, is P donghaiense Lu, and the species reported from the EastChina Sea and Japanese and Korean waters appear to be the same species. Expand
Environmental factors and seasonal dynamics of Prorocentrum populations in Nanji Islands National Nature Reserve, East China Sea
Abstract A series of samples were collected from four stations located in Nanji Islands National Nature Reserve (NINNR) from April 2006 to March 2007. During this investigation monthly samples wereExpand
