Sažetak
Zooplankton was sampled during 39 cruises, from 1990 to 1993, at four fixed stations in the open Northern Adriatic. Hydrographic factors were important in determining the abundance of the smallest and largest components of the Northern Adriatic food chain during this period. Nauplii - especially those of the smallest size fractions - were the major mediators of material transfer between primary producers and higher trophic levels. There was a significant difference in the vertical distribution of nauplii between eastern and western parts of the northern Adriatic, but not in their population density. According to multiple correlation analyses, the abundance of naupliarsize fractions in the western area correlated strongly with temperature and with certain biological factors. This study confirms the important influence of the Po River and of Middle Adriatic waters on the planktonic ecosystem of the Northern Adriatic.
