Abstract
Seasonal changes in the periphyton on the trunks of flooded trees in the Pawmpawm arm of the Volta Lake are reported. Of the three algal groups forming the periphyton, the quantitatively most important species are in such genera as Navicula, Synedra and Melosira (diatoms), Spirogyra, Oedogonium and Stigeoclonium (green algae), and Oscillatoria and Anabaena (blue-green algae). The fluctuations in species diversity and cell numbers are attributed to changes in the nutrient status of the lake water and lake level.
