These species were divided into 2 groups according to their distribution between the rainfall regions of southern Africa. Group 1, which was numerically dominant at Langebaan, was largely endemic to the winter and bimodal rainfall regions and was principally active during the winter rainy season in the south-western Cape. Group 2, which was numerically dominant at Paarl, was widespread in the winter, bimodal and summer rainfall regions and was principally active during the summer dry season and beginning of the rainy season in the south-western Cape. The potential of these beetles as control agents of the dung-breeding bush fly in south-western Australia is discussed.},

	abstract = {Climatic and biogeographical associations of southern African dung beetles (Scarabaeinae, Coprinae) were analysed from a collection amassed between 1971 and 1986. Endemism to Africa south of 15 degrees S was much greater in southwesterly climates (winter rainfall, bimodal spring/autumn rainfall, arid late summer rainfall) than to the north-east in the moist, mid- summer rainfall region. Major biogeographical groups centred to the south-west comprised predominantly southern African endemics, Western/Eastern Cape coast, Karoo, Karoo/Namib, northern Namibia and the south-western Kalahari. Biogeographical groups centred on the south-eastern highlands and the subtropical east coast (midsummer rainfall) also comprised predominantly southern African endemics. All other major groups centred to the north-east in the mid-summer rainfall region comprised predominantly species with widespread tropical biogeographical affiliations, pan-southern Africa but centred in the east, pan-mid-summer rainfall region, eastern mid-summer rainfall region, tropical east Zimbabwe/central Mocambique, subtropical/tropical game reserves (non-ruminant dung specialists). There were cross-climatic differences in taxonomic composition of the fauna. Within the winter rainfall region, percentage species composition of Scarabaeinae was greater whereas that of the coprine tribe, Onthophagini, was lower than within the other three climatic regions. Percentage species richness of most other tribes of Coprinae differed little between most climates but that of Scarabaeinae declined from west to east (Canthonini, Scarabaeini), east to west (Sisyphini) or to either side of the late summer rainfall region (Gymnopleurini).},

	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 = {Alterations in VO2 or VCO2 are amongst the more polemical physiological adaptations ascribed to insects. Generally, metabolic rate is thought to be lowered in response to arid conditions, and elevated in species from cold environments compared to their more temperate relatives. However, most studies have rarely addressed the influence of both environmental factors in unison. To this end, standard metabolic rate and its temperature dependence were measured (at 4 degrees C intervals from 16 to 32 degrees C) in six Scarabaeus dung beetle species (three flightless, three volant) from a variety of habitats (warm, arid to cool, mesic) in southern Africa using flow-through respirometry. Mass specific VCO2 varied from 0.0158 mi g(-1) h(-1) at 16 degrees C to 0.1839 ml g(-1) h(-1) at 32 degrees C. The slopes of the rate temperature curves were similar for all species (Q(10)s of 2.14-2.84), although the intercepts differed significantly in the direction (warm arid to cool mesic): S. gariepinus<S. hippocrates<S. striatum<S. galenus<S. rusticus<S. westwoodi. General Linear models were fitted to the VCO2 data with treatment temperature, wing status, mean annual rainfall and mean annual temperature as the independent variables. For all six species, the best fit model included treatment temperature and wing status only. Flightless species had significantly lower VCO(2)s than did winged ones. Amongst the flightless species, S. gariepinus, from the driest area, had the lowest VCO2. Among the winged species it was impossible to determine whether environmental temperature or water availability were most important in influencing VCO2; both were significant. We conclude that investigations of metabolic rate modulation, and especially metabolic cold adaptation, in insects must take both temperature and water availability into account.

	abstract = {Although discontinuous gas exchange cycles (DGC) are known from many insects, the effects of body size and temperature on DGC have not been widely examined. Here, these effects are investigated in five Scarabaeus dung beetle species from mesic and xeric habitats. The investigation tests two hypotheses: that previous estimates of the scaling exponents for the DGC and its characteristics are more broadly applicable to insects, and that, in response to temperature, both DGC frequency and the quantity of CO2 emitted during the open (O) phase (O-phase emission volume) are modulated. Like previous workers, we find that (V) over dot (CO2) scaled as mass(0.968) and that O-phase emission volume scaled as mass(0.968) . However, temperature- associated increases in (V) over dot (CO2) (Q(10){\textquoteright}s of 2.19- 2.65) were modulated mostly by increases in DGC frequency since O-phase volumes remained constant across temperature. Flutter (F)-phase and O-phase durations were closely coupled to DGC duration, although the relationship between closed (C)-phase duration and DGC duration was less pronounced. We show that ventilation phase coefficients, previously considered a measure of the proportional duration of each phase of the DGC, calculated from the slopes of these relationships are a measure of change in phase duration with change in DGC duration and not a measure of the way in which total DGC duration is apportioned among phases. We suggest that proportions be used to estimate the contribution of each of the phases to the total duration of the DGC.},

	abstract = {During 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{\textquoteright}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.},

	abstract = {As integral members of pasture ecosystems in warmer climates, scarabaeine dung beetles are useful indicators both of high biodiversity in untransformed pastoral regions and of healthy pastures in untransformed or intensively farmed areas. We outline the use of dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae) variously as biodiversity, ecological or environmental indicators at each of three spatial scales: regional, local, and pasture. At a regional scale, analyses of species distribution are useful both for determining regional boundaries, thus defining limits within which local comparisons are valid, and for defining group distribution centres, which facilitates comparison of biogeographical group compositions of local faunas. At a local scale, characteristic differences in species assemblage structure between natural and transformed habitats are useful both for conservation issues and for certification and marketing of high quality meat produced on natural pastures. At a pasture scale, species responses or assemblage structure may differ between dung containing residues and that lacking residues of avermectin or synthetic pyrethroid livestock pesticides. Thus, dung beetles are useful both for bioassaying the relative toxicity of old and newly developed veterinary products, and for developing more environmentally benign pest control practices. For each of the three spatial scales, we discuss goals, provide mini-reviews of pertinent results, and discuss further research.},

	abstract = {Aim (1) To review briefly global biogeographical patterns in dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae), a group whose evolutionary history has been dominated by ecological specialization to vertebrate dung in warmer climates. (2) To develop hypotheses accounting for the evolution of these patterns. Location Six principal biogeographical regions: Palaearctic, Oriental, Afrotropical, Australasia, Neotropical, Nearctic and five outlying islands or island groups harbouring endemic genera: Caribbean, Madagascar, Mauritius, New Caledonia, New Zealand. Methods Major patterns of tribal, generic and species distribution are investigated using cluster analysis, ordination, parsimony analysis of endemism and track analysis. Attempts are made to resolve biogeographical patterns with findings in the fields of plate tectonics, fossil and evolutionary history, plus phylogeny of both mammals and dung beetles. Results Because of conflict between published findings, it is uncertain at what point in time density of dinosaur dung, mammal dung or both became sufficiently great to select for specialized habits in dung beetles. However, biogeographical evidence would suggest a Mesozoic origin followed by further taxonomic radiation during the Cenozoic, possibly in response to the increasing size and diversity of mammalian dung types in South America and Afro-Eurasia. Proportional generic distribution in fourteen tribes and subtribes showed four principal biogeographical patterns: (1) southerly biased Gondwanaland distribution, (2) Americas or (3) Madagascar endemism, and (4) northerly biased, Afro-Eurasian- centred distribution with limited numbers of genera also widespread in other regions. Proportional composition of faunas in eleven geographical regions indicated three principal distributional centres, East Gondwanaland fragments, Afro- Eurasia and the Americas. These patterns probably result from three principal long-term range expansion and vicariance events (Mesozoic: Gondwanaland interchange and fragmentation, Cenozoic: Afro-Eurasian/Nearctic interchange and the Great American interchange). It is suggested that old vicariance caused by the Mesozoic fragmentation of Gondwanaland leads to a high degree of regional endemism at generic or tribal level across one or more Gondwanaland tracks. In contrast, it is suggested that the more recent Cenozoic range expansions occurred primarily towards northern regions leading to endemism primarily at species level. These Cenozoic radiations were facilitated by the re-linking of continents, either because of tectonic plate movements (Africa to Eurasia in Miocene), climatically induced sea-level change (Afro-Eurasia to Nearctic in Miocene and Pleistocene), or similar coupled with orogenics (Nearctic to Neotropical in Pliocene). Speciation has followed vicariance either because of climatic change or physical barrier development. These recent range expansions probably occurred principally along an Afro-Eurasian land track to the Nearctic and Neotropical and an Americas land track northwards from the Neotropics to the Nearctic, with limited dispersal from Eurasia to Australia, probably across a sea barrier. This accounts for the overall, spatially constrained, biogeographical pattern comprising large numbers of species- poor genera endemic to a single biogeographical region and fewer more species-rich genera, many of which show wider biogeographical distributions. In most southerly regions (Australasia, Madagascar, Neotropical), faunal composition and generic endemism is primarily dominated by elements with Gondwanaland ancestry, which is consistent with the Gondwanaland origin claimed for Scarabaeinae. In Afro-Eurasia (Palaearctic, Oriental, Afrotropical), generic endemism of monophyletically derived Afro-Eurasian and widespread lineages is centred in the Afrotropical region and faunal composition is numerically dominated by Afro-Eurasian and widespread elements. In the Nearctic region, the fauna is jointly dominated by widespread elements, derived from Afro-Eurasia, and Gondwanaland and Americas elements derived from the Neotropical region. Main conclusions Global biogeographical patterns in scarabaeine dung beetles primarily result from Mesozoic and Cenozoic range expansion events followed by vicariance, although recent dispersal to Australia may have occurred across sea barriers. Detailed phylogenetics research is required to provide data to support dispersal/vicariance hypotheses.},

	abstract = {Aim Species assemblages with high proportions of localized taxa occur in regional islands with a history of strong eco-climatic separation from adjacent systems. Current disturbance in such islands of relictualism or endemism disrupts the distinctive local character in favour of regionally distributed taxa with a wider range of tolerances. However, rehabilitation of the system should restore the localized biota. Thus, we used biogeographical composition to assess progress towards restoration of the dung beetle fauna associated with such an island of endemism following dredge-mining. Location The study was conducted in natural coastal dune forest and a 23-year chronosequence of regenerating dune vegetation in the Maputaland centre of endemism, KwaZulu-Natal, South Africa. Methods Dung beetles were trapped in eight stands of regenerating vegetation of different ages (<1 year to -21 years) and in four stands of natural dune forest with differing ecological characteristics defined by measurements of vegetative physiognomy and microclimate. Species groups defined from multivariate analysis of biogeographical distribution patterns and vegetation associations were used to demonstrate quantitative compositional changes in the dung beetle assemblages across the chronosequence to natural forest. Results Three biogeographical groups were defined. One group comprised species widespread in southern Africa or both southern and east Africa. The other two groups were endemic, one to the east coast and the other to Maputaland. There was a general trend from dominance by regionally distributed dung beetle taxa to dominance by locally distributed taxa across the chronosequence of regenerating vegetation from grassland, to open Acacia karroo thicket, to dense A. karroo-dominated woodland. However, this trend was linked closely to the relative physiognomic and microclimatic similarity between the regenerating vegetation and natural forest. Thus, proportions of locally distributed taxa were lower in older chronosequence woodland (\&SIM;18-\&SIM;21 years) with its low canopy cover and open understorey than in dense early chronosequence woodland (\&SIM;9-\&SIM;12 years), which is physiognomically and microclimatically closer to species-diverse natural forest with its dense canopy and understorey. Overall, the present dung beetle community comprises five species groups. Single widespread (21 spp.) and endemic groups (14 spp.) showed similar patterns of association with early chronosequence grassland and open thicket stands. A single widespread (3 spp.) and two endemic shade-associated groups (3 and 11 spp.) showed differing patterns of association centred, respectively, in late chronosequence woodland, natural forest, or all shaded stands. Main conclusions At 23 years, vegetative regeneration is still at an early stage, but abundant activity of most, although not all species recorded in natural forest, is recovered with the closure of the woodland canopy at \&SIM;9 years. Compositional differences with respect to natural forest vary closely with vegetative physiognomy and its effect on the microclimate. Therefore, full compositional recovery is dependent on the re-establishment of natural forest physiognomy and microclimate.},
