The high anthropogenic pressure Bandama River is undergoing is relatively of concern. Considering that the aforementioned actions could constitute a factor of imbalance in the functioning of the ecosystem, this study was carried out with the aim of determining the effect of anthropogenic pressure on the phytoplankton community. We analyzed the spatial variation of phytoplankton biovolume and its relationship with abiotic factors by sampling in six stations established on the two mains tributaries of Bandama river once a month from October 2019 to August 2020. The results showed that except dissolved oxygen, conductivity and water depth, the other physicochemical parameters did not vary significantly from one station to another. The total biovolume was dominated by the phyla of Chlorophyta 2.81.107mm3/L, Charophyta and Euglenozoa 1.63.107mm3/L and 1.53.107mm3/L respectively. The lowest average biovolume (5.34.104±3.67.104mm3/L) was determined at station S6 and the highest (3.15.105±3.03.105mm3/L) at the station of lake Kossou upstream of the dike (S1). Station S6, which is located at the confluence of the two arms of Bandama river although having the lowest biovolume, presents the greatest regularity and stability of phytoplankton communities. From the redundancy analysis (RDA), it appears that the largest biovolumes are weakly linked to the high concentrations of nitrogen, phosphorus, nitrate and nitrite in the environment. However, the transparency of the water and the dissolved oxygen are the factors discriminating the quantity of biomass. Phytoplankton, although having environmental preferences, this study made it possible to establish a negative correlation between a high phytoplankton biomass and the concentration salts.

Augustinito de la Caldera

C’è un personaggio che non conoscono in molti, eppure è un pioniere della letteratura. La cavalca con il suo puledro, sempre al galoppo. È molto difficile dormire per #Augustinito, con i sobbalzi. Persona sempre attiva… è riuscito a entrare nell’immaginario collettivo come l’eroe contadino, cavaliere dei plebei, inarrestabile sognatore. Era solito trottare su e giù dal monte Bandama almeno due…
