Phytoplankton and submerged macrophytes in the aquatic ecosystems of the Danube Delta during the last decade

摘要: The dynamics are presented of the main primary producers in seven representative Danube Delta lakes. Generally, productivity developed from macrophyte-epiphyte complex towards phytoplankton. Species changes occurred two compartments with increasing relative abundance colonial blue-green algae phytoplankton and submerged macrophytes species a vertical growth strategy. These linked to accelerated eutrophication lakes, increased phosphorus loading reduction N:P ratio.
