R., Mazzaccaro, A. 2000) Etymology . 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. Change in Reports of Paralytic Shellfish Poisoning (PSP) 1970 . Video. Large-scale bloom of Akashiwo sanguinea in the Northern California current system in 2009 Angelicque b E. Whitea,*, Katie S.

Akashiwo sanguinea has been correlated to Harmful Algal Blooms (HABs), but more study is needed to make sense of the blooms. Domoic Acid Toxicity Prediction (for cellular DA) shows the probability that the domoic acid concentration per Pseudo-nitzschia (i.e. The initial cell densities for C. geminatum and A. sanguinea were 500 cells mL −1. 2002. Hemolytic Toxicity of Three Important Harmful Microalgae Isolated from Pearl River Estuary. OHHABS Algae, Algal Toxin, and Other Pathogens Lists . The protist can produce mycosporine-like … The dorsal side is convex and the ventral side is somewhat concave. These parasites prevent repro- duction of their hosts and kill infected cells on a time scale of days. The dinoflagellate Akashiwo sanguinea is a well known, cosmopolitan harmful microalga that frequently forms harmful algal blooms (HABs) in marine estuaries from temperate to tropical waters, and has posed a severe threat to fish, shellfish, and sea birds. Hulburt, E. 1957. These results together suggest that the production of toxins by K. veneficum provides an advantage in proliferation to the species via avoiding predation, but the allelopathic effects may not play an important role in initiating blooms of the species. akashiwo (Japanese)= red tide. In general, this species is not considered to be toxic, and no toxicity or harmful activity has been verified in the IRL. Evidence that A. sanguinea … 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.

The bacterial C degradation genes (AceA-isocitrate lyase, pectinase and phenol oxidase) showed significantly positive correlations with A. sanguinea … 225-240. PLoS ONE 4: e4550. Caiyun Yang, Yi Li, Yanyan Zhou, Xueqian Lei, Wei Zheng, Yun Tian, Joy D.

Z., Turanov, A. Z., Qin, J. L., Duan, S. S. and Gobler, C. J. We are grateful for the technical help from Dr. LX Shang and Ms. H Wang. Type species . Akashiwo sanguinea is associated with harmful algal blooms ( red tides ), and is still the subject of research. Adolf, J. E., Bachvaroff, T. R., Krupatkina, D. N., Nonogaki, H., Brown, P. J.

Researchers found that the blooms are most common during mid to late summer, indicating that A. sanguinea does well in the warmer temperatures and when upwelling is sporadic and stratified conditions remain.
