A noticeable threat in Europe is the dramatic reduction in the number of cattle and sheep grazing in the open, which is associated with both intensive agriculture and the progressive reforestation of previously pastured areas. We studied dung beetle habitat and resource preferences at La Mandria Park (north-west Italy) which is a mosaic of open and wooded patches where domestic (cows and horses) and wild ungulates (deer and wild boar) co-exist. Scarabaeidae were numerically dominant, accounting for 61.5% of the approximately 3000 individuals sampled (Aphodiidae accounted for 32.5% and Geotrupidae for only 6%). However, when species richness was considered, Aphodiidae were dominant, with 17 of the 27 species found (Scarabaeidae with eight and Geotrupidae with two). Assuming a null hypothesis of equal probability of colonizing any habitat or faeces, we found that most species were significantly associated with one of the four dung types or with one of the two habitats considered. On average, Scarabaeidae preferred cattle dung and open habitats whereas most Aphodiidae used deer lumps and wooded habitats. In spite of the precise ecological choices observed at La Mandria, surveys from other European areas suggest that both habitat and food selection are quite flexible. From a conservation viewpoint, the ability of coprophagous beetles to choose herbivore faeces according to their availability and to select habitats that satisfy their own microclimate requirements may certainly be useful in preserving biodiversity. Agroecology, which implies some woodland and hedgerow management practices associated with pastoralism, could be the right approach to the management of the agricultural landscape. Conversely, in reforested areas, while wild ungulate populations should be preserved, some form of human disturbance, particularly clearings used for pastoralism, should also be maintained. 10aconservation10adeforestation10adomestic and wild ungulates10adung beetle10ahabitat and food selection10aregeneration mammals10aScarabaeoidae1 aBarbero, Enrico1 aPalestrini, Claudia1 aRolando, Antonio  uhttps://scarabnet.myspecies.info/dung-beetle-conservation-effects-habitat-and-resource-selection-coleoptera-scarabaeoidea02183nas a2200241   4500008004100000245014500041210006900186260000800255300001400263490000700277520143300284653001801717653000901735653001601744653001001760653001701770653001501787653001501802653004801817100002101865700002001886856003501906       2005                        eng d00aEffect of deforestation on a southwest Ghana dung beetle assemblage (Coleoptera : Scarabaeidae) at the periphery of Ankasa conservation area0 aEffect of deforestation on a southwest Ghana dung beetle assembl  cOct  a1081-10880 v343 aDuring June 2003, an exploratory dung beetle survey (Coleoptera: Scarabaeidae: Scarabaeinae) was conducted in southwest Ghana at the southern edge of Ankasa Conservation Area, which is a 500-km(2) conserved region of the threatened Eastern Upper Guinean rainforest. The survey provided a quantitative assessment of peripheral deforestation effects and an inventory for species on omnivore dung. Pitfall traps baited with pig dung were placed in both selectively logged and unlogged rainforest as well as in nearby oil palm and cacao plantations. The Ankasa forest inventory was mostly comprised of species previously trapped by human dung in the Western Upper Guinean rainforest of TO National Park, Cote d'Ivoire. However, there was relatively low species abundance similarity between the June/July assemblages on omnivore dung in Tai and Ankasa rainforests, and even lower similarity between assemblages of Ankasa and the adjacent plantations. Of 29 species recorded in Ankasa forest, most were absent or rare in plantations where assemblages were numerically dominated by species previously recorded from the West African savannas. This replacement plantation fauna showed significantly lower species richness and diversity, but significantly higher abundance, compared with Ankasa forest assemblages. The results reiterate that forest reserves are essential for the conservation of specialist rainforest dung beetle species.10adeforestation10aDung10adung beetle10aGhana10amodification10aplantation10arainforest10ascarabaeinae (biological conservation 2007)1 aDavis, A., L.

This study examines the role of aggregation in maintaining tropical dung beetle diversity and the effects of deforestation on aggregation patterns and diversity loss. Using clusters of pitfall traps, dung beetle aggregation was quantified in natural and disturbed habitat at nested temporal and spatial scales in central Peru. The results indicate that dung was colonized by a greater number of species, many of which were large, leading to a higher total beetle biomass in forest habitat than in deforested, farm habitat. Beetles were intraspecifically aggregated at each spatial scale examined. Habitat-type (forest/deforested) had no effect on the intensity of intra- or interspecific aggregation. Analyses of aggregation patterns revealed that dung beetle assemblages in forest habitat were generally saturated whereas in deforested habitat they were unsaturated. In general, interspecific aggregation was too weak relative to intraspecific aggregation to explain the high diversity of species in forest habitat. Other mechanisms, including resource partitioning are likely to play a greater role in maintaining the diversity of dung beetle assemblages in the region. These results also indicate that the loss of species from disturbed habitat has not been due to a breakdown in the aggregation mechanism. 10aAggregation model10abiodiversity10abiomass10acoexistence10acommunity structure10adeforestation10ahabitat change10aPeru10aScarabaeidae10aspecies richness1 aHorgan, Finbarr, G  uhttps://scarabnet.myspecies.info/aggregation-and-coexistence-dung-beetles-montane-rain-forest-deforested-siters-central-peru01961nas a2200217   4500008004100000245009200041210006900133300001400202490000700216520123800223653001201461653001801473653001801491653002301509653002201532653001101554653001701565653002201582100002301604856011601627       2008                        eng d00aDung beetle assemblages in forests and pastures of El Salvador: a functional comparison0 aDung beetle assemblages in forests and pastures of El Salvador a  a2961-29780 v173 aThis study examines the functional attributes of Neotropical dung beetles, and, based on the analysis, evaluates the role of dung beetles in pastures and tropical dry forest in El Salvador. Dung beetle diversity was lower in pastures than in forests. However, the total biomass of beetles at similarly-sized dung baits was frequently higher in pastures. Diversity loss followed structured patterns: (1) carrion and fruit feeding beetles were well represented (species number) in the forests but were largely absent from pastures; (2) large ball rollers and small fast tunnellers were present in forests but were absent from pastures; (3) large fast tunnellers and small slow tunnellers were poorly represented in pastures com- pared to forests but the few species that survived in pastures attained extremely high popu- lations; and (4) each functional group in the species-poor pasture assemblages was divided almost equally into day and night active species. Substrate and habitat generalists that were present in both the forests and pastures were attracted to fruit and carrion in forested habitat but not in open pastures. In open habitats, Xies and other insects may be the principal decomposers of decaying fruit and carrion. 10acarrion10adecomposition10adeforestation10aDiversity-function10afunctional groups10aguilds10aScarabaeidae10atropical pastures1 aHorgan, Finbarr, G  uhttps://scarabnet.myspecies.info/dung-beetle-assemblages-forests-and-pastures-el-salvador-functional-comparison03455nas a2200253   4500008004100000245014200041210006900183300001200252490000700264520258000271653001202851653001102863653001802874653001902892653001802911653001802929653001702947653002102964100002002985700002503005700001503030700001803045856013803063       2008                        eng d00aUnderstanding the biodiversity consequences of habitat change: the value of secondary and plantation forests for neotropical dung beetles0 aUnderstanding the biodiversity consequences of habitat change th  a883-8930 v453 a1. Secondary and plantation forests are becoming increasingly widespread in the tropics. A recent meta-analysis on the impacts of land-use change on tropical forest dung beetles concluded that regenerating forests can be effective in helping to offset species loss following deforestation. How- ever, our understanding of the extent to which these results can be generalized to new locations remains very poor. 2. We attempted to overcome many of the design limitations that characterize previous studies by collecting spatially independent dung beetle samples from primary, secondary and Eucalyptus plantation forests in north-east Brazilian Amazonia across a large quasi-experimental landscape that minimized confounding edge and fragmentation effects. 3. We recorded 9203 dung beetles, comprising 85 species. Species richness was significantly higher in primary forest and the majority of species were more abundant there than elsewhere, whereas secondary and plantation sites harboured an impoverished subset of primary forest species. 4. Our data illustrate the low value of tropical secondary and plantation forests for dung beetles in our study area, and our conclusions are more pessimistic than those of earlier studies. 5. Because of differences in the order of species rank-abundance and rank-biomass patterns, re-coding community data from abundance to biomass significantly altered the analytical weight of individual species in determining community patterns. Larger bodied beetles were more prone to local extinctions and abundance declines and this effect was consistent both within and between genera. 6. Synthesis and applications . Our study demonstrates that secondary and plantation forests in a large neotropical landscape host exceptionally impoverished dung beetle communities. Furthermore, the depletion of beetle abundance combined with a reduction in average body mass in converted forests is likely to have detrimental consequences for the maintenance of dung beetle-mediated ecosystem services in these habitats. Differences in biogeographical and landscape context, and the influence of common limitations in sampling design, may explain why many other studies have painted a more optimistic picture of the conservation value of anthropogenic habitats. In the absence of further evidence we caution strongly against the claim that forest regeneration schemes on degraded land can effectively offset the loss of species following deforestation, and urge that conservation strategies prioritize the protection of remaining areas of primary forest.10abiomass10abrazil10adeforestation10ahabitat change10ahabitat value10asampling bias10aScarabaeinae10aTropical forests1 aGardner, T., A.1 aHernandez, M., I.

This is no less true of dung-burying beetles (Coleoptera: Scarabaeidae: Scarabaeinae), which provide a suite of critical ecosystem functions and services, yet but face multiple conservation threats, particularly from landscape conversion. Here we use a review and meta-analysis to synthesize the current knowledge concerning response to tropical forest modification and fragmentation of dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae). For every modified habitat type and individual forest fragment across 33 studies, we calculated six dung beetle community parameters, standardized relative to intact tropical forest. We organized modified habitats along an approximate disturbance gradient ranging from selectively logged, late and early secondary forest, through agroforestry, tree plantations, to annual crops, cattle pastures and clear-cuts. Secondary forests, selectively logged forest and agroforests supported rich communities with many intact forest species, while cattle pastures and clear-cuts contained fewer species overall with few forest-dwelling species. Abundance generally declined with increasing modification, but was quite variable. Communities in open habitats were often characterized by hyper-abundance of a small number of small-bodied species, leading to low evenness. Across fragmentation studies, dung beetle species richness, abundance and evenness declined in smaller forest fragments. Richness and abundance sometimes declined in more isolated fragments, although this response appeared to depend on matrix quality. Across both habitat modification and fragmentation studies, geographic location and landscape context appeared to modify dung beetle response by influencing the available pool of colonists. We discuss potential underlying mechanisms and conclude with recommendations for management and conservation and for future research.10aAgroforestry10acommunity ecology10adeforestation10aInvertebrate10aLand-use change10aScarabaeinae1 aNichols, E.1 aLarsen, T.1 aSpector, S.1 aDavis, A., L.1 aEscobar, F.1 aFavila, M.1 aVulinec, K.  uhttp://www.sciencedirect.com/science/article/B6V5X-4ND710H-1/2/3d7a5f4362824647199ebdfd5821fa14
