RODRIGUEZ, E. ANGELICA; MANCERA PINEDA, J. ERNESTO  and  GAVIO, BRIGITTE. SURVEY OF BENTHIC DINOFLAGELLATESASSOCIATED TO BEDS OF Thalassia testudinumIN SAN ANDRÉS ISLAND, SEAFLOWER BIOSPHERE RESERVE,CARIBBEAN COLOMBIA. Acta biol.Colomb. [online]. 2010, vol.15, n.2, pp.229-246. ISSN 0120-548X.

In order to determine the occurrence of epiphytic toxic dinoflagellates in the coastal waters of San Andrés Island, Caribbean Colombia, we analyzed the seagrass beds on the northern and eastern sides of the island. We found seven species of toxicogenic dinoflagellates, belonging to the genera Prorocentrum and Ostreopsis. The cell densities were generally low if compared with previous studies in other Caribbean sites, ranging from 0 to 836 cells/dry weight. The species encountered are known to produce toxins causing the Diarrehic Shellfish Poisoning and Ciguatera, poisonings which have been documented in the island

Keywords : Epiphytes; macroalgae; Ostreopsis; Prorocentrum; Toxic dinoflagellates.
