A total of 3,430 individuals of 8 Scarabaeinae species was collected, of which 5 species are abundant in the area: Euoniticellus intermedius (Reiche), Digitonthophagus gazella (Fabricius), Onthophagus mexicanus Bates, O. knulli Howden and Cartwright, and Canthon humectus (Say). Of these 5 species, E. intermedius, D. gazella, and C. humectus were dominant in terms of abundance and biomass. Cattle dung pats were exploited mostly within the first 48 h after deposition. The activity and abundance of dung beetles recorded in the study were insufficient to remove the amount of fresh dung deposited in cattle pastureland.

We report on the discriminatory power of different data sets with regard to the classification of sites along the disturbance gradient, using preliminary data accounting for 13 surveys and 142425 arthropods collected by Malaise, pitfall and yellow-pan traps. We compared the performance of different data sets. These were based upon ordinal, familial and guild composition, or upon 22 target taxa sorted to morphospecies and either considered in toto or grouped within different functional guilds. Finally we evaluated 'predictor sets' made up of a few families or other target taxa, selected on the basis of their indicator value index. Although the discriminatory power of data sets based on ordinal categories and guilds was low, that of target taxa belonging to chewers, parasitoids and predators was much higher. The data sets that best discriminated among sites of differing degrees of disturbance were the restricted sets of indicator families and target taxa. This validates the concept of predictor sets for species-rich tropical systems. Including or excluding rare taxa in the analyses did not alter these conclusions. We conclude that calibration studies similar to ours are needed elsewhere in the tropics and that this strategy will allow to devise a representative and efficient biotic index for the biological monitoring of terrestrial arthropod assemblages in the tropics.

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.

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.

Data were obtained from March 1998 to March 1999 in tropical rain forest, induced pasture land and secondary vegetation, between 400-1000 m above sea level. Records of 7 subfamilies, 18 subtribus, 34 genera and 63 species are presented. The greatest specific diversity corresponds to Dynastinae (21 spp), Melolonthinae (13 spp), Scarabaeidae (13 spp) and Passalinae (8 spp). The 50% of the species are concentrated in the genera: Phyllophaga (9 spp), Cyclocephala (9 spp), Onthophagus (5 spp), Ataenius (3 spp), Passalus (3 spp) and Anomala (2 spp). We present a parsimony analysis of endemicity in order to know the relationships between the fauna of Cuetzalan and other Mexican localities. The fauna of Cuetzalan de Progreso is closely related to the fauna of the humid mountains of the northeast of Hidalgo. A key to the taxa found in Cuetzalan del Progreso is included.

SP - 467 EP - 475 KW - diversity KW - ecotone (biological conservation 2007) KW - edge effects KW - modification KW - selective logging AB - The role of reduced-impact logging on the preservation of biodiversity in tropical lowland dipterocarp rainforest is examined by looking at differences in dung beetle community structure between two sites logged in 1993: one harvested using reduced-impact methods and one using conventional techniques. Collections were made using two night intercept traps over 7 d, and samples were compared with previous collections made from primary forest (riverine and interior-forest) and older forest logged using conventional techniques (logged in 1981). Of the two 1993 sites, the higher diversity and species richness (S = 57, n = 969, alpha = 13.23, H' = 3.24) was recorded in the forest logged using reduced-impact techniques: the conventionally logged site had both lower diversity and species richness (S = 18. n = 1968, alpha = 8.88, H' = 1.89), and lacked some primary forest specialists present in the reduced-impact forest samples. The dung beetle community in the 1993 conventional logged site is similar to that of the conventional logging site harvested in 1981. Primary forest has a well-defined ecotone, from interior to riverine forest: both 1993 sites contain a mixture of interior-forest and riverine specialists that are usually spatially separated along this ecotone. Although the dung beetle assemblage in the forest harvested by reduced-impact logging is more similar to a primary interior-forest assemblage than the conventionally logged site, both 1993 sites have assemblages that are closer in similarity to assemblages from primary-riverine habitat than they are to ones from primary interior-forest. However, because the forest logged using reduced-impact logging techniques has a more equitable and diverse dung beetle assemblage and a greater number of interior-forest specialists than the conventionally logged site, this study suggests that reduced-impact logging has better preserved the primary forest assemblage than conventional logging techniques.

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.

Using four trap types, 14 211 insect specimens, belonging to 102 dung beetle species, 18 tiger beetle species, 16 tabanid species, and 83 butterfly species were collected and classified during 21 sampling days. Among the five habitats that were sampled, the semi-deciduous Chiquitano forest and the riverine forest showed higher species richness of dung beetles and butterflies than the Cerrado savannas and other habitats. Some taxa of dung beetles and butterflies were classified as habitat specialists, while fewer ones were classified as generalists. Preliminary data suggest that regional diversity depends more on movement of species between sites than on species richness of different habitats at each site. We discuss the limitations of this study and present recommendations for future surveys.

Location The entire French territory has been studied by dividing it into 301 grid cells of 0.72 x 0.36 degrees. Method Species richness distribution was predicted using generalized linear models to relate the number of species with spatial, topographic and climate variables in grid squares previously identified as well sampled (n = 66). The predictive function includes the curvilinear relationship between variables, interaction terms and the significant third-degree polynomial terms of latitude and longitude. The final model was validated by a jack-knife procedure. The underlying causal factors were investigated by partial regression analysis, decomposing the variation in species richness among spatial, topographic and climate type variables. Results The final model accounts for 86.2% of total deviance, with a mean jack-knife predictive error of 17.7%. The species richness map obtained highlights the Mediterranean as the region richest in species, and the less well-explored south-western region as also being species-rich. The largest fraction of variability (38%) in the number of species is accounted for by the combined effect of the three groups of explanatory variables. The spatially structured climate component explains 21% of variation, while the pure climate and pure spatial components explain 14% and 11%, respectively. The effect of topography was negligible. Conclusions Delimiting the adequately inventoried areas and elaborating forecasting models using simple environmental variables can rapidly produce an estimate of the species richness distribution. Scarabaeidae species richness distribution seems to be mainly influenced by temperature. Minimum mean temperature is the most influential variable on a local scale, while maximum and mean temperature are the most important spatially structured variables. We suggest that species richness variation is mainly conditioned by the failure of many species to go beyond determined temperature range limits.

The accuracy of spatial richness variation predictions based on area size was also checked. The log-log model (log S = c + z log A) was found to be the best-fit linear model, with slopes (z) ranging from 0.089 to 0.142. Between-group comparisons of z (slope) and q (intercept) parameters, using the S = q + cA(Z) curvilinear regression model, corroborated early results, indicating a lower beta-diversity (slope) for Scarabaeinae than for Geotrupinae and Aphodiinae. The latter group, probably more sensitive to environmental heterogeneity, should contribute more to species richness in large areas. alpha-Diversity is greater for Aphodiinae, more relevant to local diversity (1 km(2)), than for Scarabaeinae and considerably greater for these two groups than for Geotrupinae. As earlier results show that the richness of a single dung pat is rather more a function of the Scarabaeinae species pool, richness on dung pat scales is probably due more to the between-dropping mobile Scarabaeinae, while Aphodiinae contribute mainly to local and regional pool richness. Nearly 88 % of the total richness variance is explained by area size. This percentage decreases to 37 % when the spatial structure of area size and species number are extracted. The corresponding figures for Scarabaeinae, Aphodiinae and Geotrupinae are 44, 22 and 31 %, respectively. (C) 1999 Editions scientifiques et medicales Elsevier SAS.

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¢ = 1.634) than in the cultivated pasture (H¢ = 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.

Several species are of primary veterinary importance for they may act as natural enemies of pest insects that breed in this habitat. To survey the diversity and abundance of Coleoptera associated to undisturbed cattle droppings, four undisturbed cattle dung pats naturally dropped in pastures and 5 cm of the soil immediately beneath them were collected almost allweekly from april 1992 to april 1994 in a farm located in the vicinity of São Carlos, State of São Paulo, Southeastern Brazil. Beetles were collected from the pats both using Berlese funnels and by allowing the beetles to emerge for 30 to 40 days. A total of 24,332 specimens belonging to 13 beetle families and at least 66 species were identifi ed. The most abundant and diverse families were Aphodiidae, Staphylinidae and Scarabaeidae. In general, the Coleoptera were more abundant in the warmer and wet period, from October to March, with a few exceptions. The importance of the beetles, both as horn fl y natural enemies and as cattle dung decaying agents, is discussed.

KW - Scarabaeidae AB - In a gallery forest in the oriental flat lands of Meta-Colombia, dung beetles associated to three sections inside a forest with different times of alteration by deforestation (50, 5 and 1 year) were studied. Pitfall traps were used to data collection. Richness, abundance and diversity of species were calculated, during the rain season. 2358 individuals of 22 species were captured. For the three sections Canthidium cupreum was the most dominant species. 27,3% from the total species is specific from a section, 40,9% was found in two of the three sections, and 31,8% is generalists. Brillouin index showed that the forest section of 5 years of alteration has the highest diversity with 1233 individuals and 16 species, followed by the forest section of 1 year with 607 individuals and 14 species and finally the forest section of 50 years with 518 individuals and 15 species. These results indicate that a proportional relation among conservation of a forest and dung beetles diversity does not exist, and suggests a positive correlation among transformed areas and high diversity index results. Probably selective deforestation is contributing to conserve dung beetles populations inside this ecosystem, and also to maintain functional processes for this kind of forests.

Each habitat had two 20 x 20 m2 plots with 5 traps /plot. Traps were placed 2 months interval between April 2000 - June 2002. A total of 117 species from 22,177 individuals in 11 genera (Aphodius Caccobius Cassolus Catharsius Copris Onthphagus Paragymnopleurus Panellus Phacosoma Sisyphus and Synapsis) were collected from the research sites. Among those, 94 species had already been identified while 23 species were unknown. Different degree of ecosystem had effects on the dung beetles species richness and abundance. According to the Fisher’s Index, the dung beetles spechies diversity was highest in reforestation while the dung beetles species diversity in the other habitat types (Agroecosystem, Disturbed diciduous-dipterocarp forest and Undisterbed diciduous-dipterocarp forest) were not significantly different.

The results of the preliminary paper are given, which include the first two expeditions launched to the Mesay river basin, with five landscape units, and to the Sararamano river basin, with six landscape units. These landscape units were established with satellite images identified by color. A total of 4,620 individuals from 61 species and 14 genera were collected; there are differences, for the richness and diversity values, between landscape units, and also the complementarity index shows differences between some landscape units. Seven new species are new records for the Colombian Guyana region.

KW - rural area KW - Scarabaeidae AB - The most devastated environments in the State of Paraná are those with great agricultural potential, and most human interference actions on the environment are seldom preceded by a careful study of the fauna, which would reveal the diversity and abundance of animals in these areas. This study aimed to describe the Scarabaeoidea fauna attracted by light traps in rural areas of the Tamarana County, Paraná, Brazil, and to contribute to the ecological knowledge on species of this group. The sampling was carried out quarterly, from March 2002 to April 2003, in two rural properties, using a modified “Luiz de Queiroz” light trap. The light traps captured 2447 specimens, distributed into 10 families, 24 genera and 67 species. The three most abundant species were also the most frequent: Aphodius lividus (Olivier, 1789), Melolonthidae sp. 1 e Ataenius sp. 5. The highest A. lividus population density occurred in April, fall season, whereas Melolonthidae sp. 1 and Ataeucus were most frequently found in Octubre and November, spring. The majority of the species were represented by few individuals (H’= 1,74), and the distribution of individuals species was relatively uniform (J’= 0,95; S=0,20). A large number of families was recorded, and they were represented by few individuals. There was a predominance of families of detritivores - Aphodiidae, Scarabaeidae, Hybosoridae and phytophagus - Melolonthidae, Dynastidae and Rutilidae. The study collected 25 detritivore species among the 1422 specimen recorded.

This paper reports substantial ecological variation within a set of Aphodius dung beetles occurring in the same patchily distributed resource, livestock dung in pastures. We show how variation in habitat and resource selectivity, in the rate of movements between pastures, and in the distribution of local population sizes all contribute to interspecific differences in spatial population structures. Local dung beetle assemblages are compared between two landscapes with different densities of pastures. In one of the landscapes, we contrast the abundances and regional distributions of Aphodius before and after 15 years of rapid habitat loss. Different species show very dissimilar responses to changes in the structure of the landscape. Our results suggest that generalist Aphodius species, and specialist species with high dispersal powers, occur as large "patchy" populations in the landscape. In contrast? a strict pasture specialist species with limited dispersal powers (A. pusillus) forms classical metapopulations. At the community level, interspecific differences in spatial population structures make the local community composition a function of the structure of the surrounding landscape.

I suggest that targeting the regions where biogeographic assemblages intersect - " biogeographic crossroads" - is a strategy that may achieve significant conservation economy by focusing on areas that satisfy many conservation criteria. I used a combination of data on Scarabaeine beetles in Bolivia and on other taxa and locations from the literature to consider the short- and long-term benefits of conserving these biogeographic crossroads. Biogeographic crossroads are areas of high species richness and beta diversity, often across many taxonomic groups. They are also regions where representativeness can be achieved with relative efficiency. Recent evidence that ecotones may be loci of evolution suggests that evolutionary processes such as speciation and coevolution may be conserved at biogeographic crossroads. Biogeographic crossroads appear to be areas of high conservation priority and opportunity in both the short and long term and require increased attention in the process of setting conservation priorities.
