Sažetak
Benthic foraminifera are a major component of marine communities. They have ability to tolerate a broad range of environmental conditions. Dominant species have been determined ; diversity indices and foraminiferal density were calculated in surface sediments from two karstic river mouths located at east coast of the Adriatic Sea: the Cetina Estuary (CE, outer estuary, depth 30 m) and the Neretva Delta (ND, prodelta, depth 32 m). Both assemblages are dominated by Bulimina, Haynesina, Ammonia and Elphidium genera. However, these genera comprise only 37 % at CE and 70.8 % at ND of total foraminiferal assemblages. At station CE, Fisher α index reaches value of 30.83 and foraminiferal density is 860 specimens per 1 g of dry sediment. On the other hand, at station ND, α index is very low (2.72) and foraminiferal density is 36.8 specimens per 1 g of dry sediment, also. We presume that the difference between foraminiferal assemblages is result of higher river influence at Neretva Delta area.
