Sažetak
Hydromedusae Niobia dendrotentaculata and thaliacea Thalia orientalis, newly observed in the Adriatic, were recorded as dominant species in August 2006 and January 2008, respectively. Niobia dendrotentaculata with 11.2 ind./m3 made 44% of the total number of hydromedusae in the coastal area of the South Adriatic. Previously predominant (> 70%) hydromedusas in the coastal part of the South Adriatic Aglaura hemistoma contributed 38% to total number in August 2006. Similar, Thalia orientalis has replaced (with more than 55% individuals in total thaliacean) its formerly dominant congener Thalia democratica in the coastal and open south Adriatic water in January 2008. These faunal changes follow changes in zooplankton community structure recorded from 1995 in the Adriatic Sea. This coincides with - and perhaps partly are owed to - documented circulation changes in the Eastern Mediterranean, the proximate source of southern Adriatic water. Such hydrological changes were associated to large-scale hydroclimatic fluctuations, i.e. the North Atlantic Oscillation (NAO).
