Settlement of Beetles of the Wetland of Sidi Moussa-Oualidia

Iradati Tamadouni and Mohamed Arahou
Background: After a brief description of the study area and of the sampling methodology, the researchers present the commented list of beetles identified during the period 2013-2014 in the wetland complex of Sidi Moussa-Oualidia. Materials and Methods: Samples of the fauna of beetles are taken by traps barber, quadrat, sight hunting and threshing trees using the “Japanese umbrella”, in order to ensure almost complete coverage of habitat types. Results: Surveys conducted in four stations, have culminated in the identification of 40 species distributed in 24 tribes. Amongst these species, 47% are detritivores, 28% phytophagous, 17% predatory and 8% necrophagous. The trophic organization of the species is arranged by hierarchization from the shore where the predators and the granivores are preponderant towards the interior of the cultivated lands where detrivores dominate widely. The geographical distribution of the species includes several distinct categories: Mediterranean species, North African species, Moroccan endemic species and species with large distributions. Conclusion: The completion of this study allowed us to identify 40 species of beetles predominantly Mediterranean and 22% of endemic species. The composition of the population reveals an ecosystem in the process of degradation. These results should alert the authorities responsible for the danger that runs the complex and the urgency of taking appropriate measures to safeguard it.
