	abstract = {Scarab beetles colonizing vertebrate feces are considered polyphagous insects, because they often use dung of several species. However, recent works have provided evidence for strong feeding preferences in some dung beetle species. The influence of dung odors in the process of resource selection by beetles has not received attention. The objective of this study was to investigate trophic preferences in Mediterranean dung beetles colonizing cattle and horse dung. The pattern of resource use by insects was studied using series of pitfall traps baited with cattle or horse dung in three different sites of south-central France. A total of 4,276 insects belonging to 39 species were captured. Cattle dung attracted more insects than horse feces (2,570 versus 1,706 individuals). Twenty-four of the 39 beetle species collected had clear feeding preferences for cattle dung (13 species) or horse dung (11 species). None of these species seemed linked exclusively to one kind of dung. The behavioral responses of seven scarab beetles to volatile compounds emitted by cattle and horse dung were compared in laboratory olfactometer bioassays. Three insect species (Aphodius erraticus, A. scrutator, Onthophagus vacca) were more attracted to volatile compounds from cattle dung. Two other species (Euonthophagus amyntas, Bubas bubalus) orientated preferentially toward horse dung volatiles. Except for two species, beetles were thus attracted to volatiles from the dung type they preferred in the field. The reasons why coprophagous beetles show local feeding preferences for particular dung types are discussed.},

	abstract = {Dung beetle (Coleoptera:Geotrupidae, Scarabaeidae) assemblages were monitored by dung-baited pitfall trapping at three sites distributed along a bioclimatic gradient from semiarid to mesic temperate. For each type of dung, both small and large sized baits were used. Under semiarid conditions{\textquoteright}(Morocco), three dung beetle assemblages were distinguished: small bait assemblages in any dung; large cattle bait assemblages; large sheep bait assemblages. Under more temperate conditions (southern France and the Alps), only large and small bait assemblages were observed, whatever the origin of the dung. Large baits attracted significantly more species and more beetles than did small baits, and very few species were attracted significantly more by either sheep or goat baits than by cattle baits. A significant, positive correlation between dung beetle size and dung pat size was observed in Morocco where the large species are predominant, whereas a negative relationship was observed in southern France where the small species are predominant. Cattle pats were more attractive for beetles under xeric and Mediterranean conditions (Morocco and southern France) that under cold temperate conditions (Alps).},

	abstract = {1. The confidence limits and the validity of the results obtained by using dung-baited traps were examined in five sites in southern France, which were very close together and similar for most environmental variables but differed in their pastoral history. Site 1 was a virgin site which had been grazed for only a few months by cattle; site 2 had been grazed for 10 years by cattle but the cattle herd had been removed in the previous year; the other three sites had been grazed by sheep, more or less extensively, for many years. 2. Beetle abundance, biomass or richness were not correlated with temperature and precipitation, but were significantly correlated with radiant energy. The energy necessary for flight activity was probably related to the radiant energy level at the soil surface. This allowed identification of the most favourable periods for sampling. 3. At the sites with at present limited resources, the mean biomass of trapped beetles decreased rapidly when repetitive trappings were carried out over several days. An intense trapping during a continuous period led to an underestimate of the number of beetles, due to site impoverishment. When the cattle herd was removed and dung was therefore not available, the trappings made a few months later overestimated the number of beetles. In contrast, after the establishment of a new large cattle herd in a virgin site, formerly free of grazing, the baited traps underestimated the number of beetles, due to the amount of dung present in the vicinity of the traps. 4. One trapping session and five traps collected 75-80\% of total local species but 95\% of the abundance and biomass of the community. So, for most of the ecological studies, one trapping session and a few baited traps (five in the Mediterranean area where dung beetle communities are very diverse when compared with more temperate areas) are sufficient to give a sample representing the structure of the dung beetle communities. Conversely, an exhaustive inventory for biogeographical studies need more baited traps. At least 15 traps are necessary to collect 95\% of species present at a site. An abacus allows an estimate of the quality of the sampling.},

	abstract = {Aim To predict French Scarabaeidae dung beetle species richness distribution, and to determine the possible underlying causal factors. Location The entire French territory has been studied by dividing it into 301 grid cells of 0.72 x 0.36 degrees. Method Species richness distribution was predicted using generalized linear models to relate the number of species with spatial, topographic and climate variables in grid squares previously identified as well sampled (n = 66). The predictive function includes the curvilinear relationship between variables, interaction terms and the significant third-degree polynomial terms of latitude and longitude. The final model was validated by a jack-knife procedure. The underlying causal factors were investigated by partial regression analysis, decomposing the variation in species richness among spatial, topographic and climate type variables. Results The final model accounts for 86.2\% of total deviance, with a mean jack-knife predictive error of 17.7\%. The species richness map obtained highlights the Mediterranean as the region richest in species, and the less well-explored south-western region as also being species-rich. The largest fraction of variability (38\%) in the number of species is accounted for by the combined effect of the three groups of explanatory variables. The spatially structured climate component explains 21\% of variation, while the pure climate and pure spatial components explain 14\% and 11\%, respectively. The effect of topography was negligible. Conclusions Delimiting the adequately inventoried areas and elaborating forecasting models using simple environmental variables can rapidly produce an estimate of the species richness distribution. Scarabaeidae species richness distribution seems to be mainly influenced by temperature. Minimum mean temperature is the most influential variable on a local scale, while maximum and mean temperature are the most important spatially structured variables. We suggest that species richness variation is mainly conditioned by the failure of many species to go beyond determined temperature range limits.},

	abstract = {This paper addresses the association between use of a herbicide and anecdotal reports of reduced dung degradation and dung beetle populations. Dung beetles were monthly collected at two adjacent ranches in Mexico. Ranches were similar in area, elevation, exposition, soil, and vegetation, but differed in weed control. Ranch A controlled weeds manually, and ranch B controlled unwanted vegetation with applications of the herbicide Tordon(R)101M. The main species recovered on each ranch (Ataenius apicalis) was significantly more abundant at ranch A than at ranch B. Conversely, similar numbers of a second species, Ataenius sculptor, were recovered from both ranches. Three lines of evidence support the tentative conclusion that herbicide applications may be causing a decline in populations of A. apicalis on ranch B. First, the greatest reductions of A. apicalis were observed during periods of herbicide application. Second, A. sculptor, apparently little affected by these same herbicide applications, is active primarily during months without herbicide applications. Third, preliminary results of laboratory studies show that exposure to herbicide can impair reproductive function of the dung beetle Canthon cyanellus.
