Benthic Foraminiferal Assemblages in a Restricted Environment - An Example from the Mljet Lakes (Adriatic Sea, Croatia)

摘要: Benthic foraminiferal assemblages from a peculiar restricted marine environment, the Mljet Lakes (Mljet Island, Adriatic Sea, Croatia) have been studied. These lakes are drowned karst dolines, which connected with Sea through narrow, shallow channel. Occasional stagnant conditions in cause hypoxic and anoxic bottom waters. Such stressed reflected oligospecific benthic Shannon-Wiener species diversity index (H) ranging 0.8 to 1.0 equitability (E) 0.18 0.26, identified samples each lake. In more dysoxic Malo Jezero, Haynesina depressula dominates an assemblage of 12 species. less (and frequently) Veliko we found Asterigerinata mamilla s e m b l g 18 A diverse containing 55 different occupies adjacent opensea station. Long-term salinity measurements indicate that H. tolerates higher than formerly presumed (up 38 ‰), is well adapted conditions.
