Abstract
The diatoms flora of Adzopé Reservoir in Côte d’Ivoire was investigated from January to December 2005. The species composition of the assemblage was compiled, accompanied by illustrations. Firty-one taxa were identified in the temporal survey. Five taxa (16.3%) were new for Côte d’Ivoire. Eleven common species, 9 occasional taxa and 11 rare taxa were also recorded. No spatial variations in the taxonomic composition of the populations of diatoms were found. Variations were encountered in the seasonal analysis. Variation in the dimensions of some identified taxa have been observed. The species richness of Diatoms in the Adzopé Reservoir was in relation with water current velocity.
