Sažetak
Lipid classes and fatty acids of the particulate and the dissolved organic matter were investigated in the Krka River estuary (Adriatic Sea) in autumn (September 2008) and spring (May 2009) to get insight on different freshwater/marine processes taking place during different seasons. Krka River is one of the most pristine European rivers. The sampling strategy included sampling of freshwater, halocline and seawater at stations of different trophic status. Total particulate lipids showed large variations, from 12.6 to 55.4 μg/l, while total dissolved lipids varied only from 20.7 to 40.0 μg/l. Autumn was characterized by processes oforganic matter degradation, while new organic matter production takes place during spring. Fatty acid distribution patterns are used to distinguish between various sources. Bacterial branched fatty acids were very low in May. The halocline appeared to be the layer suitable for phytoplankton accumulation as revealed from higher contribution of phytoplankton polyunsaturated fatty acids (PUFA), compared to freshwater and marine layer. The comparison between estuarine and marine stations revealed that PUFA were more important at marine station although organic matter pool (DOC+POC) was lower there.
