| Streszczenie: | This study aimed to inventory, identify and describe the macroinvertebrate community in six
stations at Abiod wadi between February to June 2018, in order to know the health of the aquatic ecosystem. Physico-chemical parameters showed a significantly higher values among sampling sites (p<0.05), except for the speed of the water, which had no significant values (p> 0.05). The species were determined and the ecological indices were calculated (abundance, richness, Shannon index, Simpson index and equitability). The fauna recorded in this work is composed of 1979 individuals belonging to 31 families and 07 Orders corresponding to three faunistic groups (arthropods, annelids and molluscs). The groups with high abundance were Diptera (Chironomidae larvae) and Trichoptera. The Richness of the studied stations range from 7 families in Tiflfel station (S2) to 18 families at M’Chouneche station (S5). The values of the Shannon diversity index and Equitability were higher in M’Chouneche station (S5) (H′ = 2.537, E = 0.8776) compared with the other stations. We observed a similarity of the community structure between the six sample sites due to the constant type of habitats and the water depth. |
