    From benthic to floating: phytoplankton dynamics in African freshwater lakes and reservoirs
    (Elsevier, 2023) Dube, Timothy; Madzivanzira, Takudzwa C; Mungenge, Chipo P; Dalu, Tatenda
    This chapter reviewed phytoplankton communities in African freshwater lakes and reservoirs and further assessed the latitudinal diversity gradient (LDG) which has been used to explain species variations in other taxonomic groups. The chapter also identified freshwater reservoirs on the continent, heavily impacted by anthropogenic impacts, and assessed how these have led to changes in phytoplankton communities. From the systematic review, phytoplankton information was available for 51 reservoirs in Africa with 1633 freshwater phytoplankton species belonging to nine taxa recorded from the 51 reservoirs. There was strong evidence that supports LDG for phytoplankton species richness increased from the poles toward the Equator. Species that highly occurred in all reservoirs included Microcystis aeruginosa among other species. Despite the basal trophic importance of phytoplankton, undesirable phytoplankton blooms have been reported from several reservoirs on the continent.
