Abstract:

The aim of this study carried out in Mayo Tsanaga River was to determine the major indices which are more appropriate to characterize ephemeral stream in Sudano-Sahelian zone. Despite the influence of human activities in watershed physicochemical characteristics did not reveal a poor quality of water due to organic pollution. But the HBI values, the dominance of tolerant taxa to organic pollution on intolerant taxa at all sampling periods and the dominance of macroinvertebrates community by collectors-gatherers showed a site rich in organic matter, specially FPOM in suspension. The river is colonized by multivoltine species which are able to accomplish several life cycles during the short flow duration.


Keywords: Sudano-sahelian zone, Macro invertebrates, functional feeding groups, taxonomic approach.
