While their overall diversity and composition appear explicable in terms of historic and topographic factors, the regional variation in these communities between sample sites is argued to be a function of the interplay of the environmental requirements of the species and the quantity and quality of trophic resources available.},

	abstract = {Available information on trophic preferences of dung beetles (Scarabaeoidea) in different biogeographic regions is reviewed. Trophic resource partitioning in a dung beetle (Coleoptera, Scarabaeoidea) community in the "Parque Nacional de Donana", Spain, was also studied, using nine different kinds of wild and domestic vertebrate excrement as trap bait. Undifferentiated attraction to human and herbivore faeces was noted. Human and domestic ungulate faeces was colonized by a richer fauna than that of wild herbivores, which was not the specialized trophic adaptation of any species. Although polyphagy is the most common feeding behaviour, the excrement of carnivores and other omnivores was hardly colonized. This pattern differs from that of other biogeographic regions. Negligible importance of the trophic dimension on the structure of these communities may be due to the early presence of man in the Palaearctic Region. Nevertheless, human interference alone cannot have led to an absence of true polyphagy (undifferentiated attraction to all kinds of faeces). Further research is suggested, aimed at determining whether observed resource partitioning in dung beetles communities is a consequence of human colonization or is a pre-Neolithic evolutionary event.},

	abstract = {Under laboratory conditions brood care behaviour, nest structure and weight of dung supply in brood chambers of the dung beetle Onthophagus vacca proved to depend on water content of the soil beneath the dung. The substrate in a bucket beneath the dung pat was dry sand (4\% water content) or moist sand (8\% water content). Emigrating beetles were trapped and counted at 12 h intervals. In a total of 109 replicates one pair was released on an artificial 1000 g dung pat. From 95 replicates in which brood chambers were built the following results were derived: 1) Breeding females and resident males which helped the female stayed longer in dung pats on dry sand than in those on moist sand. 2) Nest architecture was influenced by substrate moisture: length of main tunnels did not differ between nests in dry and moist sand, but total length of side tunnels was shorter in dry sand. 3) Numbers of brood chambers were equal in both substrate types, weight of the dung supplies was larger in dry sand. 4) Offspring size was not only influenced by dung provision in the brood chambers. Beetles emerging from chambers in dry sand were smaller than those emerging from moist sand even if the amount of dung supply was equal.},
