	abstract = {The {\textquoteleft}aggregation model of coexistence{\textquoteright} predicts that a strong and independent aggregation of species across ephemeral resource patches promotes species coexistence and maintains diversity. 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. },

	journal = {Diversity and Distributions},
	volume = {12},
	year = {2006},

	abstract = {This study analyses the effect of resource availability (i.e. sheep dung) on dung beetle communities in an arid region of Central Spain, both at regional and at local scales. A total of 18 sites within 600 km2 were sampled for the regional analysis and 16 sites within the 30 km2 of an Iberian municipality were sampled for the local ana- lysis. Spatial and environmental characteristics of sampling sites were also compiled at both scales, including measures of grazing activity (livestock density at regional scale, and two counts of rabbit and sheep dung at local scale). At a regional scale, any environmental or spatial variable can help to explain the variation in abundance. However, species richness was related to summer precipitation and composition was related to elevation. At local scale, abundance is not significantly related to any of the environmental variables, but species richness was related to the local amount of sheep dung (27\% of variance). The amount of dung in a 2-km buffer around the site accounts for 27{\textendash}32\% of variance in abundance and 60{\textendash}65\% of variance in species richness. The presence of the flock with the highest sheep density explains 53\% of abundance variability and 73\% of species richness variance. A cluster analysis of localities identified two main groups, one characterized by a lower abundance and species richness that can be considered a nested subsample of the species-rich group. The mean and maximum amount of sheep dung in the sites separated by less than 2 km are the only significant explanatory variables able to discriminate both groups. These results suggest that grazing intensity (and the associated increase in the amount of trophic resources) is a key factor in determining local variation in the diversity and composition of dung beetle assemblages. However, dung beetle assem- blages are not spatially independent at the analysed resolution, and the amount of dung in the surroundings seems to be more important for locally collected species than the dung effectively found in the site. Although differences in the availability and quantity of trophic resources among nearby sites could be affecting the popula- tion dynamics and dispersion of dung beetles within a locality, sites with larger popu- lations, and greater species numbers would not be able to exercise enough influence as to bring about a complete local faunistic homogenization.},

	abstract = {We linked primary dispersal by spider monkeys (Ateles geoffroyi) and howler monkeys (Alouatta pigra) to post-dispersal seed fate by studying the effects of dung type and defecation pattern on secondary seed dispersal by dung beetles. First, we described the defecation patterns for both primate species. Howler monkeys generally defecated in groups (88\% of observed defecations), with each individual producing on average 31 g of dung, resulting in a large area of the forest floor (31 m(2)) covered by large amounts of dung (clumped spatial pattern). Spider monkeys generally (96\% of observed defecations) defecated individually, each individual producing an average of 11 g of dung, resulting in a small area of the forest floor (2 m(2)) covered by small amounts of dung (scattered spatial pattern). Secondly, we captured dung beetles using as bait the dung of both primate species, to detect differences in the assemblages of these secondary seed dispersers attracted to the dung of both primates. More individual dung beetles, but not more species, were attracted to howler monkey dung than to spider monkey dung. Finally, we assessed experimentally (using plastic beads as seed mimics) how dung type (Ateles vs. Alouatta) and defecation pattern (scattered vs. clumped) affect secondary seed dispersal by dung beetles. We found that post-dispersal seed fate was affected by dung type, with more seeds being buried when present in howler monkey dung, than in spider monkey dung, but was not affected by defecation pattern. It is important to consider post-dispersal processes, such as secondary seed dispersal by dung beetles, when comparing species of primary dispersers.},

	abstract = { 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 {\textquotedblleft}Luiz de Queiroz{\textquotedblright} 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{\textquoteright}= 1,74), and the distribution of individuals species was relatively uniform (J{\textquoteright}= 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. },
