In the Pineto Urban Regional Park (Rome), dog dung is the sole food resource currently available for scarab dung beetles, after the recent removal of wild and domestic herbivores. A one-year sampling was conducted to study the scarab assemblage in dog scats (1999) and to compare it with the previous assemblage associated with sheep droppings (1986). Richness, evenness and similarity parameters were compared between the two allochronic assemblages. From sheep to dog dung, an impoverishment of the total richness was observed (from 19 to 9 species) together with an increase of individuals (by 7 times). Dog dung harboured 20\% of the current scarab dung beetle fauna of Rome, probably as a consequence of the dog mixed diet, rich in cellulose. Both the communities showed a high percentage of tunnellers, probably because of the food shortage and, for dog scats, of the high dehydration rate. A comparison with other Roman scarab communities enhanced that: (1) the change in food resource determined a higher difference in species composition respect to other parameters (size and habitat diversity); (2) dog dung provided a temporary refuge for species that otherwise may encounter local extinction in urban environments.

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.}, keywords = {bait, burial, capacity, cattle dung, COLEOPTERA, colonization, communities, dung beetle, Dung beetles, feces, food, horse dung, mammal mammals, olfactometer, Scarabaeidae, Scarabaeoidea, trophic preferences}, url = {://000220856500033}, author = {Dormont, L. and Epinat, G. and Lumaret, J.

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).}, keywords = {aphodius, assemblage composition, ba, baited pitfall traps, cattle, COLEOPTERA, colonization, dung beetle, GUILD, IVERMECTIN, mammal, patterns, Scarabaeidae, Scarabaeoidea, scarabaeoidea col communities, spatial, trophic resource, variability}, url = {://000189311200006 }, author = {Errouissi, F. and Haloti, S. and Jay-Robert, P. and Janati-Idrissi, A. and Lumaret, J.

This paper reports on Aphodius dung beetle movements at two scales: movements between dung pats within pastures, and movements between pastures. First, I test an assumption common to many recent models of spatially structured populations - that the probability of an individual moving between habitat patches decreases exponentially with distance. For dung beetles, I find sufficient evidence to reject this assumption. The distribution of dispersal distances was clearly leptokurtic, with more individuals moving short and long distances than expected on the basis of an exponential function. In contrast, the data were well described by a power function. I conclude that dung beetle movements include an element of non-randomness not captured by the simplistic exponential model. The power function offers a promising alternative, but the actual mechanisms behind the pattern need to be clarified. Second, I compare several species of Aphodius to each other. Although these species occur in the same network of habitat patches, their movement patterns are different enough to result in a mixture of different spatial population structures. Movements between pastures were more frequent the larger the species, the more specific its occurrence in relation to pat age, and the more specialized it is on cow dung and open pasture habitats. Within pastures, all species form "patchy" populations, with much movement among individual pats.}, keywords = {APHODIUS SCARABAEIDAE, butterfly, colonization, euphydryas-editha-bayensis, long-distance dispersal, melitaea-cinxia, metapopulation structure, migration, patch size, proclossiana-eunomia lepidoptera, resource utilization}, url = {://000166017800013}, author = {Roslin, T.} }
