Abstract
The effect of environmental conditions on bacterial community structures, production and enzymatic activities was studied in north-eastern Adriatic in the late spring of 2009 in waters belonging to the two gyres, the cyclonic (CG) and the anticyclonic (AG) one, and in waters non-affected by presence of the two gyres. The AG and CG were formed in a same pool of warm, low salinity, nutrient rich waters characterized with increased autotrophic production and abundances. Differences in bacterial community structures and in intensities of cell-specific prokaryotic production and enzymatic activities indicated that CG and AG were isolated cells in which water resided for different time period. Bulk prokaryotic production and enzymatic activities were significantly lower in region outside the influence of the gyres. Bacterial communities of these waters, particularly in deeper layers, were likely introduced by high salinity oligotrophic waters from central AdriaticKeywords
