Sažetak
Surface sediment samples from Mljet Lakes and adjacent open sea (south-eastern Adriatic coast, Croatia) were analyzed for stained and total foraminifer content in relation to water depth and substrate characteristics. Foraminifer distribution changes substantially in a short distance. The assemblages from muddy substrate samples are predominantly hyaline, poor in term of specimens and species. The assemblages from sandy substrate samples consist of abundant permanently mobile porcelaneous species, rich in number of specimens and species. Primary conclusion of this study is that the shallow-water foraminiferal distribution in this peculiar environment is governed by a complex interaction between several environmental constrains (enclosed nature of the Mljet Lakes , its particular hydrography, occasional anoxia). Reduction of foraminiferal species observed in a 10 years period suggests dynamics of environmental conditions reflected in changed microhabitats. In spite of the peculiarity of the investigated area, the observed pattern of foraminiferal distribution might be useful in paleoenvironmental interpretation.
