Abstract

The abundance of Synechococcus and Prochlorococcus were determined at twenty-one stations located along the eastern coast of the central and southern Adriatic and at three stations located in the open central Adriatic Sea. Synechococcus abundance ranged from 102 to 105 cells mL-1 in the coastal area, and from 103 to 104 cells mL-1 in the open sea Prochlorococcus abundance in the coastal area ranged from 0 to 104 cells mL-1, and from 103 to 10 4 cells mL-1 in the open sea. The seasonal distribution of Synechococcus and Prochlorococcus mostly showed an increase in abundance during the warmer period and a decrease during winter. The highest abundance of Synechococcus was found in Kaštela Bay with values at 4.6 x 10 5 cells mL-1, while the highest abundance of Prochlo-rococcus was determined in the Šibenik area and recorded as 7.1 x 104 cells mL-1 Synechococcus was found to be more abundant than Prochlorococcus in most cases. The abundance of Synechococ-cus was influenced more by temperature than nutrient availability. The abundance of Prochlorococ-cocus was influenced by nutrient availability and the movement of water masses more than by HNF.
