dc.description | Phytoplankton is one of the primary components of marine aquatic environments, in the coral reefs their play a fundamental role, because they provide food to corals and secondarily zooplankton feed their prey, thus they promote important trophic interactions in this ecosystem. Degradation of these ecosystems at a global level has caused, among many of the factors, an increase in the abundance of phytoplankton species due to the increase in nutrients and sediments that do not favor the health of the reefs. The Nacional Natural Park Corales del Rosario and San Bernardo is affected during the rainy season mainly by continental discharges, this study contributes with detailed data of the phytoplankton community that occurs and the relative abundance in the Protected Area during this period time. 16 samples were collected in the season with the highest rainfall between 2016 and 2019 in four stations within the Nacional Natural Park area were analyzed, using horizontal drags with a 63- µm net. 228 phytoplankton morphospecies were identified that correspond to species from shallow and coastal water environments, diatoms were the most representative group during 2016, 2017, and 2019, with the presence of species such as Skeletonema costatum, Chaetoceros affinis, Bacteriastrum furcatum. During 2018 dinoflagellates increased their representativeness above diatoms and with the presence of species with harmful potential such as Pyrodinium bahamense, Alexandrium monilatum, which presented the highest relative abundances in this year. | en-US |
dc.description | El fitoplancton es uno de los componentes primarios de los ambientes acuáticos marinos. En los arrecifes de coral, tiene un papel fundamental porque provee alimento a los corales y, secundariamente, da alimento al zooplancton, por lo que crea interacciones tróficas importantes en este ecosistema. El deterioro de los arrecifes a nivel global ha ocasionado, entre muchos otros factores, un aumento en la abundancia de especies de fitoplancton debido al incremento de nutrientes y sedimentos que no favorecen a la salud de estos ecosistemas. En el Parque Nacional Natural Corales del Rosario y de San Bernardo, en particular, estos efectos se perciben durante la época de precipitaciones, principalmente por descargas continentales. Por lo tanto, este estudio intenta contribuir con información detallada de la comunidad fitoplanctónica que se presenta en el área protegida y la abundancia relativa durante dicho periodo. Para esto se analizaron 16 muestras recolectadas en la temporada de mayor precipitación entre 2016 y 2019 en cuatro estaciones dentro del área del parque, mediante arrastres horizontales con una red de 63 µm. Se identificaron 228 morfoespecies de fitoplancton que corresponden a especies de ambientes de aguas someras y costeras. Las diatomeas fueron el grupo de mayor representatividad durante 2016, 2017 y 2019, con la presencia de especies como Skeletonema costatum, Chaetoceros affinis y Bacteriastrum furcatum. Durante 2018 los dinoflagelados aumentaron su representatividad por encima de las diatomeas, con la presencia de algunas especies con potencial nocivo como Pyrodinium bahamense y Alexandrium monilatum, las cuales registraron las mayores abundancias relativas en ese año. | es-ES |
