| description |
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. |

Gran parte de estos dinoflagelados son productores de toxinas causando síndromes de intoxicación en regiones tropicales y subtropicales. En ocasiones, cambios en los factores ambientales pueden desencadenar grandes proliferaciones denominadas “blooms”. Por tal motivo, el objetivo de este estudio es caracterizar la comunidad de microalgas epibentónicas potencialmente tóxicas a lo largo de la costa norte del Ecuador en la Reserva Marina de Galera San Francisco (RMGSF), y en su Archipiélago en la Reserva Marina de Galápagos (RMG) sobre diferentes especies de macrófitos. En la RMGSF, en Estero de Plátano, perteneciente a la provincia de Esmeraldas, se muestreó de noviembre 2016 a mayo 2017 los géneros de macroalga Padina y Coralina, recolectando un total de 36 muestras. En la RMG, las microalgas fueron recolectadas en tres sitios Bahía Tortuga, Santa Fé y Venecia, durante el mes de abril 2017 a través de 17 muestras de macroalgas verdes, pardas y rojas. En ambos lugares se determinó la presencia del género Ostreopsis sp, encontrando una mayor diversidad y abundancia de especies en Galápagos. En la RMG se identificó también Gambierdiscus sp en una de las muestras estudiadas, además de géneros como Prorocentrum, Amphidinium y Coolia. La presencia de estas microalgas potencialmente tóxicas a lo largo de la región litoral e insular del Ecuador podría asociarse a las condiciones ambientales favorables y a las características climatológicas de las áreas de estudio convirtiéndolas en ecosistemas propicios para el desarrollo y proliferación de estos microorganismos.Pontifica Universidad Católica del Ecuador Sede Esmeraldas2018-06-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.pucese.edu.ec/hallazgos21/article/view/235Revista Científica Hallazgos21; Vol. 3: SUPLEMENTO ESPECIAL2528-79152528-7915reponame:Revista Pontificia Universidad Católica del Ecuador - Sede Esmeraldasinstname:Pontificia Universidad Católica del Ecuador - Sede Esmeraldasinstacron:PUCESEspahttps://revistas.pucese.edu.ec/hallazgos21/article/view/235/141Derechos de autor 2018 Hallazgos21, develando ciencia por el desarrolloinfo:eu-repo/semantics/openAccess2019-11-19T14:38:11Zoai:ojs.pkp.sfu.ca:article/235Institucionalhttps://revistas.pucese.edu.ec/Universidad públicahttps://www.pucese.edu.ec/..Ecuador.2550-665X1390-9800opendoar:02025-04-20T07:36:34.763824Revista Pontificia Universidad Católica del Ecuador - Sede Esmeraldas - Pontificia Universidad Católica del Ecuador - Sede Esmeraldastrue |
