“…Cochlodinium polykrikoides Margalef is an unarmored dinoflagellate that has caused catastrophic HABs in the Caribbean Sea, eastern and western Pacific Ocean, the western Atlantic Ocean, Indian Ocean, Mediterranean Sea, and the Arabian Gulf (Margalef, 1961;Matsuoka et al, 2008;Richlen et al, 2010;Kudela and Gobler, 2012). The initiation and development of C. polykrikoides blooms have been shown to be related to diurnal migration behavior (Park et al, 2001;Y.-S. Kim et al, 2010), mixotrophy (Jeong et al, 2004), light quantity and quality (Oh et al, 2006), the production of toxins lethal to grazers (Jiang et al, 2009;Tang and Gobler, 2009a,b), allelopathic effects on competing phytoplankton , transport by large-scale currents (Onitsuka et al, 2010), and stimulation by nutrients such as nitrogen and vitamins .…”

“…This species has been documented in coastal areas throughout tropical and temperate regions, since it was first described by Margalef (1961) from Puerto Rico in the Caribbean Sea. According to Matsuoka et al (2008), chain-forming Cochlodinium species similar to C. polykrikoides have been reported previously in East and Southeast Asia, North and Central America, the Indian Ocean, and the Mediterranean as www.elsevier.com/locate/hal Available online at www.sciencedirect.com Harmful Algae 7 (2008) 271-277 § Disclaimer: This publication does not constitute an endorsement of any commercial product or intend to be an opinion beyond scientific or other results obtained by the National Oceanic and Atmospheric Administration (NOAA).

RESUMENEn este estudio se analizaron los eventos de floraciones algales nocivas (FAN) en cuatro estaciones de muestreo fijas en el Golfo de Nicoya durante el periodo de enero de 2008 a diciembre de 2010. Se recolectaron muestras de agua a 1 y 5 m de profundidad durante cada evento de FAN. Además, se midieron in situ los parámetros fisicoquímicos: profundidad del disco de Secchi, temperatura, salinidad, oxígeno disuelto y el porcentaje de saturación de oxígeno del agua. Los datos de radiación solar y precipitación fueron suministrados por el Instituto Meteorológico Nacional de Costa Rica. Se determinaron las concentraciones de las microalgas responsables y las especies asociadas. Se registraron 11 eventos, de los cuales el 72.7% se presentaron en la época lluviosa y un 27.3% en la época seca, la mayoría de éstos, durante el fenómeno atmosférico de La Niña. Las especies responsables fueron los dinoflagelados Alexandrium monilatum, Levanderina fissa, Cochlodinium polykrikoides y Prorocentrum minimum, la diatomea Skeletonema costatum y la cianobacteria Trichodesmium erythraeum. Las especies asociadas que se registraron con mayor frecuencia fueron los dinoflagelados Dinophysis caudata, Prorocentrum micans, Tripos fusus, Tripos furca y Protoperidinium conicum. Las FAN en el Golfo de Nicoya fueron más frecuentes durante la época lluviosa, probablemente debido a los aportes fluviales al sistema estuarino de los ríos Tempisque, Barranca y Grande de Tárcoles. Esa estacionalidad, en conjunto con las alteraciones provocadas por eventos atmosféricos globales como La Niña y El Niño, determinó la formación de FAN en el golfo durante el periodo de estudio.Palabras claves: Floraciones algales nocivas, microalgas responsables, condiciones ambientales, El Niño y La Niña, Golfo de Nicoya. ABSTRACTHarmful Algal Blooms (HABs) events were analyzed in this study at four monitoring stations in the Gulf of Nicoya between January 2008 and December 2010. Water samples were collected at 1 and 5 m deep during each HAB event. Furthermore, the following physicochemical parameters were measured in situ: Secchi disk depth, temperature, salinity, dissolved oxygen, and saturation percentage of oxygen in water. Radiation and precipitation data was provided by the National Meteorological Institute of Costa Rica. The concentration of dominant microalgae and associated species was determined. A total of 11 events were recorded, 72.7% during rainy season and 27.3% during dry season, most of them during the La Niña atmospheric phenomenon. Dominant species included the following dinoflagellates; Alexandrium monilatum, Levanderina
