Alexandrium monilatum. (1984). It’s called Akashiwo Sanguinea. Z., Qin, J. L., Duan, S. S. and Gobler, C. J. Cas Key Laboratory of Marine Ecology and Environmental Sciences, Institute of Oceanology, Chinese Academy of Sciences, Qingdao, China, College of Earth And Planetary Sciences, University of Chinese Academy of Sciences, Beijing, China. In China, the first In China, the first A. sanguinea bloom was recorded in Yantai in 1998. 2000) to transfer the species to the new genus. It occurs only in the seaward regions of San Francisco Bay [ Cloern and Dufford , 2005 ], suggesting that it is an allochthonous species produced in the coastal ocean and transported into the Bay by density‐driven currents or tidal dispersion. Foam in Monterey Bay National Marine Sanctuary Foam created by the dinoflagellate Akashiwo sanguinea along the shoreline in Monterey Bay. Aquatic Microbial Ecology, 80(3), 209-222. Akashiwo sanguinea is a harmful—but not toxic—species that causes blooms around the world. … Live Akashiwo sanguinea. (, Zhou, C., Fu, Y., Chen, Q. and Yan, X. They have a large number of yellow or brown chloroplasts that radiate from the cell center with a nucleus in the middle that is distinguishable by appearing as a clear area. Microbiol.

(, Deeds, J. R., Kibler, S. R., Tester, P. A. and Place, A. R. (, Deeds, J. R., Mazzaccaro, A. In An Unusual Bloom of the dinoflagellate Akashiwo sanguinea off the Central Oregon USA, scientists wanted to find the rise and demise of a sudden algae bloom of the coast in Oregon. Change History. A. sanguinea can produce mycosporine -like amino acids as water-soluble, surface-active substance ( surfactant) reduces the surface tension of the water. Acute toxicity of the cosmopolitan bloom-forming dinoflagellate Akashiwo sanguinea to finfish, shellfish, and zooplankton AME 80:209-222 | Full text in pdf format. Karlodinium veneficum is a cosmopolitan, toxic, and harmful algal bloom-forming dinoflagellate, of which the mixotrophy has been suggested to be a key factor in the formation and maintaining of HABs and thus deserves more intensive explorations.

The taxonomy of unarmored Dinophyceae of shallow embayments on Cape Cod, Massachusetts. The allelopathic and toxic potencies among K. veneficum strains were not parallel, which indicates that the allelochemicals and fish-killing toxins of K. veneficum may be different chemicals, or the same responsible chemicals functioned in different modes to algae and animals. Otherwise, vegetative cell division is the normal means of reproduction. 2.1 Study Area. The cingulum is approximately median and slightly descending. Akashiwo sanguinea. Toxicity (cyanobacteria only) ... Akashiwo sanguinea Alexandrium monilatum . Parasitism of photosynthetic dinoflagellates by three strains of Amoebophrya (Dinophyta): parasite survival, infectivity, generation time, and host specificity. Genes linked to the Akashiwo sanguinea community. In this study, we analyzed free-living bacterial communities from Xiamen sea during an Akashiwo sanguine bloom using Illumina MiSeq sequencing of 16S rRNA gene amplicons. In this study, we analyzed the carbonyl compounds from eight common HAB-forming species ( Akashiwo sanguinea, Karenia mikimotoi, Karlodinium veneficum, Margalefidinium polykrikoides, Prorocentrum donghaiense, P. minimum, Scrippsiella trochoidea , and Heterosigma akashiwo ) using gas chromatography-mass spectrometry in full scan and selected ion monitoring (SIM) modes. Domoic Acid Toxicity Prediction (for cellular DA) shows the probability that the domoic acid concentration per Pseudo-nitzschia (i.e. NIES-1832 : Akashiwo sanguinea (Hirasaka) Hansen & Moestrup : Subculture; Unialgal; Clonal; Non-axenic Not available; Fragile species to transportation stresses; Read and agree "How to order 4.1" For questions, comments or contributions, please contact us at: ABSTRACT: Parasitic dinoflagellates of the genus Amoebophrya commonly infect free-living dino- flagellates, some of which cause toxic or otherwise harmful red tides. (, Heisler, J., Glibert, P. M., Burkholder, J. M., Anderson, D. M., Cochial, W., Dennison, W. C., Dortch, Q., Gobler, C. J. et al. Here, we report an investigation on the phagotrophy of K. veneficum using a clonal culture isolated from the coastal water of East China … 38: 520-528. (, Xu, N., Tang, Y.
