Studies on cyanoprokaryotes of the water bodies along the Bulgarian Black Sea Coast (1890-2017): A review, with special reference to new, rare and harmful taxa

The report presents a review of the studies on cyanoprokaryotes from Bulgarian coastal wetlands carried out in the period 1890-2017. The biodiversity of cyanoprokaryotes in coastal water basins (their phytoplankton and phytobenthos) was evaluated and analyzed by wetlands types with emphasis on the new and peculiar taxa described. The conservation status of the recorded species follows the Red List of Bulgarian microalgae. Special attention is paid to the occurrence of cyanoblooms, cyanotoxins and toxic species, as well as to the invasive and alien species.
