The effects of ecological gradients on epiphytic benthic dinoflagellates found in Hawaiian waters
Ciguatera fish poisoning is thought to be caused from the toxin producing dinoflagellate, Gumbierdiscus toxicus. Many reports have shown an increase in ciguatera outbreaks in areas where there was previous disturbance to the reef. These disturbances open up new substrate for macroalgae and microalgae such as G. toxicus to settle and grow upon. Coastal development also has an impact on coral ree...
متن کاملToxicity of benthic dinoflagellates on grazing, behavior and survival of the brine shrimp Artemia salina
Harmful algae may differently affect their primary grazers, causing sub-lethal effects and/or leading to their death. The present study aim to compare the effects of three toxic benthic dinoflagellates on clearance and grazing rates, behavioral changes, and survival of Artemia salina. Feeding assays consisted in 1-h incubations of brine shrimps with the toxic Prorocentrum lima, Gambierdiscus ex...
متن کاملAssociated bacterial flora, growth, and toxicity of cultured benthic dinoflagellates Ostreopsis lenticularis and Gambierdiscus toxicus.
The growth, toxicity, and associated bacterial flora of 10 clonal cultures of the toxic benthic dinoflagellates Ostreopsis lenticularis and Gambierdiscus toxicus isolated from the coastal waters of southwest Puerto Rico have been examined. Clonal cultures of O. lenticularis grew more rapidly and at broader temperature ranges than those of G. toxicus. All five Ostreopsis clones were toxic, while...
متن کاملDistribution of the heterotrophic dinoflagellate Pfiesteria piscicida in Korean waters and its consumption of mixotrophic dinoflagellates, raphidophytes and fish blood cells
To explore the distribution of Pfiesteria piscicida in Korean coastal waters, we analyzed the morphology and DNA sequence of several isolates collected from 6 locations along the southern and western Korean coasts. We also investigated the prey species consumed by a Korean isolate and determined the growth and ingestion rates of P. piscicida when it fed on the dinoflagellate Amphidinium cartera...
متن کاملFirst Report of sp. Parasites Infecting Dinoflagellates from Brazilian Coastal Waters Amoebophrya
Members of the parasitic dinoflagellate genus lethally infect other marine dinoflagellates, including red tide forming and toxin-producing species. The known geographical distribution of sp. parasites in costal waters of the northern hemisphere is more likely reflecting a lack of information from other areas rather than the actual picture. We investigated the presence of sp. parasites infecting...
