Sažetak
The planktonic diatoms belonging to two genera Chaetoceros and Bacteriastrum, included within the family Chaetocerotaceae, are ecologically important as they represent an important component of the phytoplankton in the coastal regions and are often among bloom-forming taxa. We analysed the chaetocerotacean species composition and abundances in the coastal area of northeastern Adriatic in a biweekly study conducted from September 2008 to October 2009 with the aim of investigating seasonal dynamics and species succession on a fine temporal scale and determining the most important ecological factors influencing their distribution. The study identified seven Chaetoceros and three Bacteriastrum species as major phytoplankton components showing the clear annual succession and two types of blooms (one species/multi species) governed by differing ecological conditions. Autumn bloom was composed of 20 chaetocerotacean species with Chaetoceros contortus and Chaetocerosvixvisibilis alternating in dominance. The summer period was characterized by spreading of freshwater from the Po River up to the eastern coast increasing availability of phosphate which triggered the monospecific Chaetoceros vixvisibilis bloom. We explained the chaetocerotacean dominant species succession pattern by the environmental parameters, with the temperature, salinity and phosphate availability as most important factors driving the species seasonality.
