Phytobenthos - Key Biological Element in Shallow Marine Waters
AbstractThe present paper describes the situation of the macroalgal flora from the past years (2009-2012) along the Romanian Black Sea coast, from the qualitative and quantitative point of view. Key species (Cystoseira barbata and Zostera noltei) are characterized and their role for the communities inhabiting the shallow marine waters is highlighted. Also the pressures that have negatively affected the development of macroalgal flora over the years, leading to decline (in some cases irreversible) of some species are described. In order to answer to the requirements of the Water Framework Directive the biological element macroalgae is used and indicators able to characterize the water bodies from the ecological point of view are applied.
