Sažetak
Year-to-year fluctuations in the abundance of zooplankton (1960-1982) and bacteria (1968-1988) were examined. Three main patterns of year-to-year changes in abundance were extracted by Principal Component Analysis (PCA):(1) Cyclical oscillations with 5.5 yr periodicity. This pattern is well correlated with salinity and southerly weather type (lower atmospheric pressure, south-easterly wind and higher precipitation) and can be accounted for by the water exchange between the Mediterranean and the Adriatic Sea. (2) Long-term trend of increasing abundance presumably due to the open Adriatic eutrophication. (3) Oscillations with 7.3 yr periodicity. This pattern is well correlated with temperature.
