Abstract

Dung beetles feed on and bury animal droppings, and their role is crucial in reducing the accumulation of manure, which diminishes the useful surface area of pastures. The aim of this research was to characterize the seasonal organization of dung beetle communities (Coleoptera: Scarabaeoidea) in the Middle Atlas region of Morocco in terms of core and satellite species. The beetles were collected using standard dung-baited traps. Four sites along a gradient of elevation were surveyed for one year every 7 to 10 days, depending on the season and local weather conditions. A total of 24,397 beetles were collected, belonging to 51 species. In most dung beetle communities, two to three species were found to be predominant, representing between 70 and 95% of all the individuals active at the same time but constituting only 10 to 30% of species diversity. The rapid succession of species at the same site limits the competition between species, allowing for the efficient use of available trophic resources.
