Περιγραφή:From March 2012 to March 2013, and from September 2013 to August 2014, biodiversity and abundance of tintinnids and its relationship with environmental variables were determined in two Marine Areas for Responsible Fisheries (AMPR) (Puerto Níspero and Paquera) of Gulf of Nicoya, Costa Rica. For both sampling areas, it was determined seasonality of the physicochemical parameters influenced by the climate variability of the zone, which was evidenced by the significant differences in the sampling time. Tintinnids population showed a low diversity of species where the main representatives were Tintinnopsis parva, T. uruguayensis, and Tintinnidium balechi; and their abundance ranged from a 0 to 5583 cells L-1. By correlating the abundance of tintinnids regarding environmental variables studied in each sampling site, a tendency for significant interactions were negative, mainly tintinnids abundance and concentration of dissolved oxygen in both AMPR. Also, environmental variables interrelate with respect to temporal behavior of the abundance of tintinnids; it was determined whether there is a relationship between the increase in the concentration of organisms and environmental variation. Overall, the presence of tintinnids shows the natural process of the trophic web, ensuring a productive dynamics at the base of the food chain of the study areas.
