| Sumario: | Epi-benthic microalgae communities are organisms that are usually attached to the marine substrate and sometimes on macroalgae, most of these dinoflagellates are producing toxins causing intoxication syndromes in tropical and subtropical regions. At times, changes in environmental factors can trigger large blooms called blooms. Therefore, the objective of this study is to characterize the community of potentially toxic epibenthic microalgae along the northern coast of Ecuador in the Galera Marine Reserve and its Archipelago in the Galapagos Marine Reserve (RMG) on different species of macrophytes. In the northern part of Ecuador, in Estero de Plátano, in the province of Esmeraldas, the genres Padina and Coralina were sampled from November 2016 to May 2017, collecting a total of 36 samples. In the RMG, the microalgae were collected in three sites: Tortuga Bay, Santa Fe and Venice, during the month of April 2017 through 17 samples of green, brown and red macroalgae. In both places the presence of the genus Ostreopsis sp was determined, finding a greater diversity and abundance of species in Galapagos. In the RMG Gambierdiscus sp was also identified in one of the studied samples, in addition to genera such as Prorocentrum, Amphidinium and Coolia. The presence of these potentially toxic microalgae along the coastal and insular region of Ecuador could be associated with favorable environmental conditions and the climatological characteristics of the study areas, making them ecosystems conducive to the development and proliferation of these microorganisms. |
