Fine spatial and temporal phytoplankton variability in Mali Ston Bay has been observed for the first time based on physicochemical properties and small herbivorous zooplankton. Extensive year-through research was conducted during 2002 at Usko station which is traditionally an area of intensive shellfish farming. The Neretva River inflow, submarine springs(More)
Phytoplankton distribution and environmental characteristics were determined in a shallow, highly stratified and oligotrophic estuary (Zrmanja, eastern Adriatic). Samples were collected in two contrasting seasons; winter (February 2000), when river discharge was high, and in summer (July 2003), a period of drought. Phytoplankton distribution was closely(More)
Frequent sampling at a fixed South Adriatic station over 1996 was designed to capture the annual cycle of life-history stages of the dominant gelatinous invertebrate zooplankton, which are very seldom encountered in the world literature. Two groups of dominant species were distinguished by their periods of most intense reproduction, one in late(More)
The Mali Ston Bay has been qualified as a moderately/naturally eutrophicated ecosystem. Extensive phytoplankton blooms (red-tides) were not recorded. One hundred and ninety-five phytoplankton taxa were determined in the bay so far. The phytoplankton species composition and diversity reflect stable conditions throughout most of the year. Although toxic(More)
Deep chlorophyll amaximum (DCM) was found in the 80–110m deep northeastern coastal Adriatic (Pag and Velebit Channels) in July 2007. Eight times higher concentrations of chlorophyll were determined in the 50 to 60 mDCM layer (0.81 to 0.91 mg L–1) relative to the surface waters. According to thermohaline conditions and phytoplankton biomass distribution,(More)
The abundance, biomass and species composition of phytoplankton were determined in relation to hydrographic conditions in the highly stratified Zrmanja Estuary, eastern Adriatic coast, Croatia, during the October 1998 episode of strong river outflow. Phytoplankton accumulated around the halocline in the middle portion of the estuary, where nanoplankton(More)
This paper describes the plant communities of two oligotrophic karstic rivers with a slight anthropogenic influence — the Trebižat and the Lištica — in South Bosnia and Herzegovina, their sinecology, and the relationship between vegetation and plant species and environmental parameters. According to 87 relevés, a total of 26 plant associations, using(More)

Gruž Bay (south-eastern Adriatic) is moderately eutrophicated, mostly by discharge from the karst river Ombla. Input of inorganic nitrogen might be attributed to enrichment from the open sea during strong and continuous north winds in winter 1988/89. Annual succession of primary producers, herbivores and decomposers was defined by seven stages and induced(More)
The recruitment of leaping grey mullet, Liza saliens juveniles in the Neretva River estuary (middle eastern Adriatic Sea, Croatia) started in July, was highest in August, decreased in September, and was unobserved later. The juveniles firstly occupied mouths of rivers and channels and then started migrating to more freshwater habitats. By feeding(More)
