	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 = {Circellium bacchus is a flightless telecoprid (ball-rolling) dung beetle, endemic to the afrotropical region, where it is found in a few restricted populations in the eastern Cape of South Africa. Its apterous condition and large size (mass ranges from 6 to 12 g) are considered to be adaptations to a semi-arid habitat. This beetle is active in the sun for long periods, walking between widely scattered dung pats, thus is under selection pressure to reduce water loss. C bacchus has eight spiracles on each side of the body. The metathoracic spiracle and six abdominal spiracles open into the sub-elytral cavity, which is closed. The mesothoracic spiracle is the largest and most exposed, occurring ventrally in the membrane connecting the prothorax and mesothorax. When at rest a cyclic form of respiration, known as discontinuous gas exchange cycle, is used by C. bacchus, releasing a burst of carbon dioxide approximately once an hour when the spiracles open for about 33 minutes. Flow-through respirometry was used to measure water loss from the thorax (being the head, prothorax and mesothorax) and elytral case (containing the metathorax and abdomen) separately. The total water loss of C. bacchus could be divided up as 65\% cuticular water loss from the thorax, 35\% cuticular water loss from the elytral case, 4\% respiratory water loss from the thorax and no measurable respiratory water loss from the elytral case. 1.51 mug of water is lost for every mul of CO2 emitted during respiration in the thorax. Thus, the main avenue for both respiration and respiratory water loss is via the mesothoracic spiracles, suggesting that the primary function of the subelytral cavity is not to reduce respiratory water loss.},

	abstract = {The sealed subelytral cavity of many flightless beetle species is widely acknowledged to be an adaptation to water saving in arid-habitat species. However, this hypothesis relies on the acceptance of two largely untested assumptions: (i) that the movement of respiratory gases is unidirectional from anterior to posterior and (ii) that the coordinated action of the spiracles directs this flow. We tested these assumptions by simultaneously measuring CO2 and O2 exchange at the anterior mesothorax, independently of gas exchange in the posterior body, which included the subelytral cavity, of a large apterous beetle, Circellium bacchus. Flow-through respirometry revealed a marked discontinuous gas-exchange cycle (DGC) pattern from the anterior half of the body. Very little CO2was released from the posterior body, where the DGC was not apparent. Labelled air was shown to flow forwards from the posterior to the anterior body. Individual sampling from the mesothoracic spiracles revealed that the right mesothoracic spiracle, lying outside the elytral cavity, is the primary route for respiratory gas exchange in C. bacchusat rest. This discovery necessitates a reassessment of the currently assumed role of the subelytral cavity in water conservation and is, to our knowledge, the first demonstration of forward airflow associated with the unilateral use of a single thoracic spiracle for respiration in an insect. },

	abstract = {The effect of seed burial by dung beetles on seed survival and seedling establishment in Tetragastris altissima (Burseraceae) was measured on 3 sites of continuous forest and 7 islands in the man-inundated rain forest of Saint-Eugene, French Guiana. Experiments using a total of 250 seeds were performed using wire enclosures open to dung beetles but excluding terrestrial seed predators. Fragmentation had no effect on the rate of dung disappearance at 12, 24 and 48 h because there was a high variability between sites. On average, 24 \% of seeds were buried by dung beetles after 72 h, Overall, there was no effect of fragmentation due to variation between sites. Dung burial rates were positively correlated with rarefaction of the dung beetle samples collected on the different sites. They were also positively correlated with weighted abundances of large diurnal tunnellers after 12 h and to total tunnellers after 24 h. Seed burial was positively correlated to weighted abundance of large nocturnal tunnellers and of total tunnellers. The species diversity and abundance were positively related to area that did not involve a correlation between seed burial rates and area. After 72 h, survival rate of protected seeds at ground surface was significantly larger (78 \%) than for non protected seeds (22 \%), which were attacked by rodents. There was no difference between continuous forest and islands. Eight percent of buried seeds emerged, i.e. 2 \% of all seeds deposited. Burial depth significantly affected the rate of emergence of buried seeds. Ninety percent of seeds at surface germinated versus 0 \% at 10 and 15 cm. The effects of seed burial by dung beetles on early recruitment of T altissima was low and highly variable between sites in relation with the structure of the community of Scarabaeidae and intensity of seed predation.},

	abstract = {Field experiments investigated the colonisation by a north temperate dung beetle community (Aphodius, Geotrupes and Sphaeridium species) of artificial, standardised (11) dung pats from native herbivore species (cow, horse and sheep). An additional experiment compared the colonisation by dung beetles of five different types of cow dung. These experiments did not examine naturally occurring dung pats, but used experimental dung pats to examine the ability of north temperate dung beetles to discriminate among different dung types. A small number of laboratory experiments investigated pat residence times (PRT) and larval production across different dung types. There were significant differences in the biomass and abundance of dung beetle colonisation across different dung types. Sheep dung tended to have highest abundances of beetles, but there was evidence of species-specific differences in dung beetle colonisation of the different kinds of dung. In two out of three comparisons, laboratory experiments provided evidence that adult PRT were significantly different among different kinds of dung. In each of three laboratory experiments, larval production was significantly higher in sheep than cow dung pats of the same size. The relevance of these findings to the interpretation of what constitutes a dung type preference is discussed. (C) 2002 Elsevier Science B.V. All rights reserved.},

	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.},
