	abstract = {Biodiversity loss can precipitate extinction cascades and impair ecological processes. These {\textquoteleft}downstream{\textquoteright} effects will be exacerbated if functionally important taxa are tightly linked with species threatened by extinction or population decline. We review the current evidence that such a scenario is currently playing out in the linked declines of persistently hunted<br />
mammal populations and the dung beetles communities (Coleoptera: Scarabaeidae: Scarabaeinae) that depend on them for adult and larval food resources. Through a close evolutionary association, mammal assemblages have played a fundamental role in structuring extant dung beetle communities. Today many game mammal species{\textquoteright} populations are severely depleted by subsistence or commercial hunting, especially in tropical forest systems. Multiple lines of evidence from temperate and tropical systems indicate that the regional-scale decline or extirpation of medium and large bodied mammal faunas can severely disrupt the diversity and abundance of dung beetle communities through alterations in the composition and availability of dung resources. These observed community disassemblies have significant short- and long-term implications for the maintenance of key ecosystem processes including nutrient recycling and secondary seed dispersal. Identifying the species- and community-level traits that buffer or exacerbate these species and functional responses is essential if we are to develop a better understanding of the cascading ecological consequences of hunting in tropical forests.

	abstract = {There is increasing concern about the conservation of dung beetles which are threatened by several peculiar dangers worldwide, both at the population and community level. 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. },

	abstract = {To determine the degree of completion of Western Palaearctic dung beetle species inventory, as well as to ascertain some of the main geographical and morphological characteristics associated with the probability of new species description, the available taxonomic and biogeographic information of the three Scarabaeoidea families that are associated with dung was analyzed. An asymptotic fit of the cumulative number of described species is used to estimate the approximate number of species not yet described. Variation partitioning and hierarchical decomposition techniques were used to explore the influence of body size, geographical range size and geographical location variables on the process of species description. Results indicate that the inventories of Western Palaearctic Scarabaeidae and Geotrupidae species are almost complete, but that around 16\% of Aphodiidae species have yet to be described. As the joint effect of geographical distribution and location is the main determinant of the species description rate in this family, it was predicted that new dung beetle species would be found in smaller areas of the southern and eastern Western Palaearctic region. The species body size accounted for a negligible fraction in the variation of the year of description. Both the geographical range size and the geographical location are essential variables negatively correlated with the year of species description, whose pure and combined effect can account for high percentages in the year of description variation (from 41 to 56\%). The location of most of the taxonomic workforce in areas where broader-ranged generalist species prevail in the assemblages is the probable reason for this pattern.},

	abstract = {Dung beetles are useful as indicators in conservation and global warming studies owing to their specialized regional and local distribution patterns. However, existing South African data are inadequate for indication at the necessary degree of spatial resolution. To improve the database, Survey methods need to Lie designed according to the spatial and temporal factors that influence dung beetle diversity. Across four major climatic regions, there are seven principal species distribution centres for dung beetles in which activity is influenced primarily by difference, in rainfall seasonality and temperature, Across these regions, generic endemism is largely concentrated around the coastline and in montane areas. The conservation status of endemic genera is discussed. At a local scale, spatial diversity is influenced primarily by soil, vegetation and dung type. Maximum local diversity of dung beetles is observed after rainfall and decreases as surface conditions become warmer and drier. After workshop discussions, a coarse-grained, asymmetrical gradsect survey grid has been designed according to vegetative, climatic and land-usage gradients across South Africa. It is suggested that each survey point across these regional gradients should comprise a quarter-degree square in which local ecological gradients should be surveyed for invertebrates, Baited pitfall trapping is an easy method to provide quantitative data for dung beetles across such environmental gradients. Lining up each catch on a tray provides a relatively quick way to compare the specimens, identify the species present, and provide a quantitative assessment of species abundance. Data collection may be conducted on one or more occasion., to accommodate seasonal and daily variation in species occurrence. This exercise could identify localities suitable for ecotourism reserves representative of the variation in ecotypes across the country, particularly, in coastal, natural grass and wooded regions, where many invertebrate taxa are endangered by habitat fragmentation including some rare dung beetle species.},

	abstract = {A faunistic and conservation-oriented analysis of the Scarabaeoidea beetles from the Hidalgo State, México is presented. Seven families with 95 genera and 276 species are recorded, of which five genera and six species are considered introduced. Fifteen species are cited for the first time for this state and 21 species are considered to be erroneously or doubtfully recorded for Hidalgo. Thus, Hidalgo is the fifth Mexican state with the highest number of Scarabaeoidea species. On the basis of estimates of species numbers of several biological groups, it is extrapolated that at least 100 species are missing to record from this state. According to the geographical distribution of the species, six groups are proposed (with the exception of introduced species): endemic from Hidalgo (13 spp.), endemic from México (104 spp.), North American (37 spp.), Central American (55 spp.), Latin American (32 spp.), and American (29 spp.). With respect to the vegetation types of the state, the coniferous forest has 92 species of which 37 are restricted to this forest, the oak forest 71 species and none are restricted, the cloud forest 108 species with 34 restricted, the tropical evergreen and semideciduous forests 108 species with 29 restricted, the tropical deciduous forest 69 species with one restricted, and the xerophilous scrub 52 species with 12 restricted. The distribution of the species by biogeographical provinces shows that 62.1 \% of the total species are exclusively located in the Sierra Madre Oriental, 13.8 \% in the Altiplano Mexicano, 3.8 \% in the Eje Neovolcánico Transmexicano and 1.9 \% in the Golfo de México. With regard to endemism of Hidalgo and México, the coniferous forest presents 60 species, the cloud forest 59 species, the oak forest 44 species, the tropical evergreen and semideciduous forests 16 species, the xerophilous scrub 13 species, and the tropical deciduous forest nine species. With regard to the four federal protected natural areas of the Hidalgo state, it is necessary to carry out a systematic faunal work at the Biosphere Reserve Barranca de Metztitlán, due to the lack of data of scarab beetles from this and many other arid and semiarid areas of México. It is also important to complete the faunal inventories of the areas with coniferous and oak forests, among them the National Parks Los Mármoles and El Chico. In addition, it is advisable to conduct supplementary collections in areas with tropical deciduous forest, since information on scarab beetles in this forest in Hidalgo state is scarce. On the basis of the high values of richness, endemism and restricted species numbers of the scarab beetles inhabiting the cloud forests, it is urgent to propose protected areas in the state of Hidalgo with this type of vegetation. It is also necessary to obtain more information on the eco-geographical distribution of scarab beetles from Hidalgo, in order to propose species into categories of risk. Likewise, the present-day number of protected natural areas is considered inadequate to preserve this insects group.},

	abstract = {The responsiveness of South African fauna to climate change events is poorly documented and not routinely incorporated into regional conservation planning. We model the likely range alterations of a representative suite of 179 animal species to climate change brought about by the doubling of CO2 concentrations. This scenario is expected to cause a mean temperature increase of 2 degreesC. We applied a multivariate climate envelope approach and evaluated model performance using the most comprehensive bird data set. The results were encouraging, although model performance was inconsistent in the eastern coastal area of the country. The levels of climate change induced impacts on species ranges varied from little impact to local extinction. Some 17\% of species expanded their ranges, 78\% displayed range contraction (4-98\%), 3\% showed no response and 2\% became locally extinct. The majority of range shifts (41\%) were in an easterly direction, reflecting the east-west aridity gradient across the country. Species losses were highest in the west. Substantially smaller westward shifts were present in some eastern species. This may reflect a response to the strong altitudinal gradient in this region, or may be a model artifact. Species range change (composite measure reflecting range contraction and displacement) identified selected species that could act as climate change indicator taxa. Red-data and vulnerable species showed similar responses but were more likely to display range change (58\% vs. 43\% for all species). Predictions suggest that the flagship, Kruger National Park conservation area may loose up to 66\% of the species included in this analysis. This highlights the extent of the predicted range shifts, and indicates why conflicts between conservation and other land uses are likely to escalate under conditions of climate change.},

Endemism was examined in relation to whether the species were shared with Nicaragua and/or Panama, or if they were strictly Costa Rican.  The species composition of dung beetle distributions in the sampling areas and life-zones was evaluated.  Species distribution was also analyzed in relation to altitudinal levels.  The species richness and endemicity maps served as a base for doing a gap analysis and defining four different levels of high priority conservation areas.  We also investigated what percentage of these priority areas is under some type of protection or conservation scheme and which of these areas should be enlarged.  Also considered is the feasibility that these areas under protection have for enlargement, considering possible problems and interactions with present land-use.  We include a list of all the recorded dung beetle species for Costa Rica, as well as their presence in the different Holdridge life-zones and their endemicity status.  This study clearly demonstrates the need to include insects in biodiversity-endemicity studies because different and more detailed results are obtained in relation to vertebrate and plant-based studies.},

The beetles{\textquoteright} activity is governed by precipitation and temperature; 18-26 "C and high relative humid- ity favour activity. The beetles are generalist dung feeders and breeders but have clear preferences for elephant dung for feeding, and buffalo dung for breeding. Fecundity is the lowest recorded for a dung beetle, with a maximum of two but on average only one progeny produced per year. The species is unique amongst ball-rolling (ielecoprid) dung beetles in that females initiate, form and roll brood balls, something carried out exclusively by males in other species. The beetles are habitat specialisrs prefening dense undisturbed vegetation to more open, dis- turbed vegetation. The species should be considered rare because of its narrow geographical range, restricted biotope specificity and biological attributes. Fur- thermore, ii complies with most of the characteristics that increase its likelihood of endangerment or extinction and qualifies as "vulnerable" according to IUCN criteria of threatened species.},

	abstract = {In Mediterranean countries, inventories of many animal groups particularly insects, are incomplete or nonexistent. Hence, a feasible spatial picture of unequally surveyed areas is required to ascertain which faunistic surveys are good enough to produce reliable estimates of species richness. We used generalized linear models to build a multiple-regression function through which we predicted the distribution of Iberian dung beetle species richness. Given the scarcity and unevenness of the species-richness spatial distribution, the number of records of a dung beetle database (BANDASCA), falling within each of the 50 x 50 km grid squares, was chosen as a measure of the sampling effort for that square. Examining the asymptotic relationship between the number of dung-beetle species and database records for each physioclimatic Iberian subregion, we found that 82 grid squares (32\% of the total) were adequately sampled. Dung-beetle species richness was related in each of these 82 cells to 24 explanatory variables. Curvilinear functions, interaction terms, and the significant third-degree polynomial terms of latitude and longitude were included to model species-richness distribution. The final model accounted for 62.4\% of the total deviance after we eliminated seven outlier squares, with maximum elevation, grassland area, land-use diversity, forest area, geological diversity, interaction of terrestrial area and maximum elevation, and interaction between calcareous rock, and geological diversity and latitude being the most significant independent variables. The residuals of the function were not spatially autocorrelated, and we validated the final model by a jackknife procedure. Large and environmentally complex hotspots in the Iberian Central, Baetic, and Subbaetic mountain ranges stand out from the emerging map of species richness. Further detailed research is required to determine the complementarity of the faunas of these two main hotspots, the key question in conservation planning for a dung-feeding beetle.},

	abstract = {Abstract. The Pantanal is one of the faunistic provinces considered as a priority area for inverte- brate conservation. However, it is one of the areas in Brazil where the local fauna is less assessed, thus needing more scientific information that could allow political decisions to be made regarding conservation. The continuous pressure for new pasture areas leads to improper habitat occupation and destruction, like fragmentation of forest areas in the region. Such alterations can cause different impacts on the local fauna, including the soil arthropods. The main objective of this work was to compare the morphospecies composition, diversity and density of the soil arthropod fauna between a secondary single species forest (Cambarazal) and a cultivated pasture with exotic and native grass species, using only pitfall traps as sampling method. We found a great variation on the vegetal cover among environments. A higher humidity in the forest soil was observed, as well as a greater com- paction of the soil in the cultivated pasture. A total of 3635 individuals were collected, belonging to 214 different morphospecies. 139 morphospecies were collected in the forest (37\% exclusive to this environment), while 134 morphospecies were collected in the cultivated pasture (35\% exclusive). The diversity was higher in the forest (H{\textcent} = 1.634) than in the cultivated pasture (H{\textcent} = 1.253). How- ever, considering the area as a whole (forest and pasture) the global diversity was increased. In this paper we discuss about the effects of environmental changes on soil arthropod diversity and propose a hypothetical model for invertebrate management in mosaic ecosystems.},

	abstract = {1.Bioindicators of habitat quality and environmental change must be identified quantitatively and tested independently to confirm their usefulness. We used the indicator value (IndVal ) method, which combines measures of habitat fidelity and specificity, to assess the indicator responses of dung beetles (Coleoptera: Scarabaeidae) in Tembe Elephant Park, South Africa. The indicator responses were verified by sampling in different areas of the Park, 2 years after the responses were originally quantified. 2. We postulated that terrestrial insect indicators with different combinations of habitat specificity and fidelity might fulfil different indicator roles. Indicator species with strong habitat specificity (characteristic species) are unlikely to provide information on the direction of ecological change despite high vulnerability. Rather, detector species that span a range of ecological states are likely to be better in this role. We used IndVal for selecting such detector species that indicate the direction of ecological change. 3. Sets of species were found to be robust bioindicators, i.e. reliably characteristic across the habitat of which they were indicative. The suite of indicators was refined by discarding those with IndVal s that varied significantly across years, thus improving the confidence in the final suite of species selected. By clearly responding to a change in habitat between two ecological states, detector species provided information complementary to that provided by characteristic species. 4. The IndVal method enabled both the identification and testing of indicator (characteristic and detector) species. Because of its resilience to changes in abundance, IndVal is a particularly effective tool for ecological bioindication. 5. We conclude that both characteristic and detector species are useful bioindicators of habitat quality and conversion. We propose that bioindicators that are categorized and verified in this way will have valuable application in the monitoring of habitat integrity.},

Local technicians are responsible for the day-to-day gathering of data. The existing monitoring protocols for blue monkey, silver-cheeked hornbills, trumpeter hornbills, forest interior dung beetles and Asplenium nidus have sufficient statistical power (>0.80) to detect trends of 65\% or less over a 10-year period. Monitoring protocols for black and white colobus and Asplenium holstii have lower statistical power (<0.80). We therefore conclude that the majority of monitoring protocols of the East Usambara Ecological Monitoring Project have the capacity both logistically and statistically to detect long-term trends in important functional groups in the East Usambara Mountains.},

	abstract = {Habitat fragmentation and the widespread creation of habitat edges have recently stimulated interest in assessing the effects of ecotones on biodiversity. Ecotones, natural or anthropogenic, can greatly affect faunal movement, population dynamics, species interactions, and community structure. Few data exist, however, on insect community response to forest- savanna ecotones, a natural analog to anthropogenically cleared areas adjacent to forest. In this study, the abundance, total biomass, average individual biomass, and distribution of scarabaeine dung beetles were examined at a sharp tropical evergreen forest-savanna ecotone in Santa Cruz, Bolivia. The abundance, total biomass, and average individual biomass of dung beetles varied significantly across the forest, edge, and savanna habitats. Species richness (S-obs) also varied significantly across the three habitats, but statistical estimations of true species richness (S-est) did not. Habitat specificity of the dung beetles in this study was extremely high. Of the 50 most common species collected during the study, only 2 species were collected in both the forest and savanna habitats, signaling nearly complete community turnover in just a few meters. Strong edge effects were evidenced by the decline in abundance, total biomass, and species richness at the forest-savanna boundary.},

	journal = {Biological Conservation},
	volume = {134},
	year = {2007},
	pages = {113-121},
	abstract = {We used dung beetles as an indicator group to identify the most important habitats for bio- diversity conservation in a Mediterranean traditional agroecosystem. The relationships between traditional grazing and farming activities and biodiversity were analysed by com- paring species richness and temporal turnover across three different habitat types, defined according to vegetation structure and human land use. In this study, both spatial (land- scape, among-habitats) and temporal (intra-annual, seasonal) analyses were contemplated at mesoscale. The measurement and use of temporal beta diversity (i.e. an index of temporal species turnover) in conservation biology showed that it is a simple method to characterize and compare different habitat species-assemblages, particularly when time seems to be a sig- nificant factor in explaining biodiversity features. Our results showed open mosaic areas as the richest and most temporally heteroge- neous habitats. We suggest the maintenance of traditional human activities carried out in these areas, since they have been a significant diversification agent, to avoid the loss of the high Mediterranean biological diversity. },
