Phytoplankton communities are widely used as indicators of trophic status and eutrophication in freshwater ecosystems. This is particularly true for tropical reservoirs, which are strongly influenced by seasonal and human activities. The present study examined the structure, diversity, and spatial and temporal dynamics of phytoplankton communities in Taabo lake (Côte d’Ivoire). Sampling was conducted over a one-year period, from November 2017 to October 2018. Five sampling sites were monitored during contrasting four seasons. Phytoplankton composition, abundance, and environmental variables were simultaneously assessed. A total of 242 phytoplankton taxa belonging to seven phyla were identified. Chlorophyta represented the most taxonomically diverse phyla. Despite the high taxonomic richness, phytoplankton composition showed strong similarity among sites. In contrast, phytoplankton abundance was largely dominated by Cyanoprokaryota throughout the study period. The most abundant species were Pseudanabaena limnetica and Microcystis aeruginosa. Phytoplankton densities increased markedly during the rainy seasons, coinciding with higher concentrations of nitrogen and phosphorus. Diversity and evenness indices were significantly lower at sites (S1 and S2) affected by fish farming activities. This pattern reflected the dominance of a few opportunistic Cyanoprokaryota species under nutrient-enriched conditions. ReDundancy Analysis demonstrated that seasonal variations in nutrient availability, conductivity, lake depth, and water transparency were the main factors structuring phytoplankton communities. Overall, the results indicate that Taabo lake exhibits clear symptoms of eutrophication. Nutrient enrichment, combined with seasonal hydrological dynamics, strongly controls phytoplankton structure and promotes Cyanoprokaryota dominance.
