The aim of this study was to identifythe abundance of the phytoplankton communities associated with the MARF to determine theseasonal changes between abiotic variables and phytoplankton in the Paquera-Tambor MARF,Gulf of Nicoya, Costa Rica. Monthly sampling (September 2013 to August 2014) was performedfor physical-chemical factors and phytoplankton. The data showed a temporal variation of bothenvironmental factors and the phytoplankton community. The most representative microalgaewere diatoms and dinoflagellates with a richness of 51 and 32 species, respectively, where thepresence of some algal bloom forming species such as Cochlodinium catenatum was highlighted,with a concentration of 5.85x104 cells L-1. Regarding diatoms and parameters such as Secchi diskdepth (r = -0.558) and the percentage of oxygen saturation (r = -0.490), a negative correlation was found due to climate variability in the area. Zooplanktonic tintinnids were identified and showed a positive correlation with diatoms (r = 0.433). A fundamental ecosystem dynamic was evident for the trophic development of the Tambor-Paquera-MARF, which underpins the importance of the fishing zone and reflects the relevance of continued biotic and abiotic monitoring for the area. 2016 artículo científico 1659-455X https://www.redalyc.org/articulo.oa?id=633766725002 en http://www.redalyc.org/revista.oa?id=6337 Revista Ciencias Marinas y Costeras application/pdf Universidad Nacional de Costa Rica Revista Ciencias Marinas y Costeras (Costa Rica) Num.2 Vol.8 |
