Toxicity 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 کاملThe 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 کاملFish-derived nutrient hotspots shape coral reef benthic communities.
Animal-derived nutrients play an important role in structuring nutrient regimes within and between ecosystems. When animals undergo repetitive, aggregating behavior through time, they can create nutrient hotspots where rates of biogeochemical activity are higher than those found in the surrounding environment. In turn, these hotspots can influence ecosystem processes and community structure. We...
متن کاملMycosporine-like amino acids from coral dinoflagellates.
Coral reefs are one of the most important marine ecosystems, providing habitat for approximately a quarter of all marine organisms. Within the foundation of this ecosystem, reef-building corals form mutualistic symbioses with unicellular photosynthetic dinoflagellates of the genus Symbiodinium. Exposure to UV radiation (UVR) (280 to 400 nm) especially when combined with thermal stress has been ...
