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.10aAnimalia-10aArthropoda-10aBehavior-10aChordata-10aColeoptera-: Insecta-10aDigestive-System (Ingestion-and-Assimilation)10adung-beetles (Coleo10aEcology- (Environmental-Sciences)10aHominidae-: Primates-10aInvertebrata-10aMammalia-10aNutrition-10aVertebrata-1 aMartin-Piera, F.1 aLobo, J., M.  uhttps://scarabnet.myspecies.info/comparative-discussion-trophic-preferences-dung-beetle-communities02941nas a2200289   4500008004100000245011200041210006900153300001200222490000700234520197600241653001402217653001602231653002802247653001402275653004202289653002602331653001502357653003802372653001802410653001402428653001602442653001502458653001602473653001602489100002002505856012602525       1995                        eng d00aSelection of the spatial habitat of Coprophagous beetles in the Kaiserstuhl area near Freiburg (SE-Germany)0 aSelection of the spatial habitat of Coprophagous beetles in the   a461-4780 v163 a1. In an all-year-round survey of coprophagous beetles in a pasture in the Kaiserstuhl area (SW-Germany), cow-pats and sheep lumps were gathered from two field areas and one wooded area twice a month. 40,298 beetles belonging to 40 species of Scarabaeoidea and 14 of Hydrophilidae were detected. The small site on the Kaiserstuhl has the highest species diversity of Scarabaeoidea species among all local dung beetle coenoses described in Europe thus far. 2. In all seasons of the year, population density and biomass of dung beetles were higher on the open pastures than in the wooded pasture. Only in summer and on the coldest days of winter, values of both macrohabitats were approximately the same, which might be due to the mediated climate of wooded habitats in those seasons. 3. 11 out of 29 abundant species showed a clear preference for open macrohabitats, while only four preferred the wooded macrohabitat. All other species were eurytopic. Faunistic similarity was low among all three macrohabitats and did not show closer relationships between the two open pastures than between both of them and the wooded pasture. 4. Sheep lumps were more densely populated than cow-pats, whereas the latter contained a higher biomass in dung beetles. The cow-pat community was higher in species number as well as in diversity. Faunistic similarity between both dung beetle communities was minimal. 5. 13 out of 32 abundant dung beetle species preferred each dung type. Mean size of Scarabaeoidea dung beetles preferring sheep lumps was significantly lower than of those preferring cow-pats. Regardless their size difference, all but one Hydrophilidae species showed a pronounced preference for cow-pats. 6. Selection of the spatial habitats played a minor role in compartmentation of the total niche space of the dung beetle community as compared to temporal niche dimensions such as seasonality. As in the case of seasonality, Aphodius was best separated within the genus.10aAnimalia-10aArthropoda-10aBovidae-: Artiodactyla-10aChordata-10aClimatology- (Environmental-Sciences)10aColeoptera-: Insecta-10acow- (Bovi10aEcology- (Environmental-Sciences)10aInvertebrata-10aMammalia-10aMetabolism-10aNutrition-10aPhysiology-10aVertebrata-1 aWassmer, Thomas  uhttps://scarabnet.myspecies.info/selection-spatial-habitat-coprophagous-beetles-kaiserstuhl-area-near-freiburg-se-germany
