Sažetak
Northern Adriatic Sea is an oligotrophic shallow basin (with average depth 35 m) relatively small in volume (635 km3) spreading over the area of 19000 km2. However, due to intense nutrient-rich freshwater inflows, with major impact of the Po River, western part of northern Adriatic is eutrophic. Influence of the trophic state in different parts of the region reflects on the qualitative and quantitative characteristics of the phytoplankton, indicating even some species as possible indicators. Over the past decades, qualitative changes of the phytoplankton community were observed. With statistical analyses of solely phytoplankton as well as together with environmental data, we aim to explain long-term changes and differences in this region to result from the following: nutrient concentration and ratio variations primarily due to freshwater inflow oscillations of Po River, decrease of phosphorous due to its reduction in the Italian detergents during the eighties and the trend of sea surface warming which also started in the eighties.
