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. 10aAggregation model10abiodiversity10abiomass10acoexistence10acommunity structure10adeforestation10ahabitat change10aPeru10aScarabaeidae10aspecies richness1 aHorgan, Finbarr, G  uhttps://scarabnet.myspecies.info/aggregation-and-coexistence-dung-beetles-montane-rain-forest-deforested-siters-central-peru01365nas a2200253   4500008004500000245018500045210006900230300001200299490000700311520043300318653001400751653002400765653001700789653001500806653001600821653002200837653001100859653001700870653002500887653002100912100002000933700002000953856013800973       2006                        spandsh  00aLos escarabeidos y geotrupidos de la comunidad de Madrid: lista de especies, distribucion geografica y patrones de diversidad (Coleoptera, Scarabaeoidea, Scarabaeidae y Geotrupidae0 aLos escarabeidos y geotrupidos de la comunidad de Madrid lista d  a419-4380 v623 aIn this work we summarize the main characteristics of Geotrupidae and Scarabaeidae (Coleoptera, Scarabaeoidea) fauna inhabiting Comunidad de Madrid, including an upda- ted checklist of species as well as maps representing the observed and potential distri- butions of all species.

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 27–32% of variance in abundance and 60–65% 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.10aResource availability10aScarabaeidae10asemi-arid ecosystems10asheep grazing activity10aspecies richness determinants1 aLobo, Jorge, M.1 aHortal, Joaquin1 aCabrero-Sanudo, Francisco-Jose  uhttps://scarabnet.myspecies.info/regional-and-local-influence-grazing-activity-diversity-semi-arid-dung-beetle-community00833nas a2200217   4500008004400000245015300044210007100197300000900268490000700277653001500284653001700299653001400316653001400330653002100344653001700365653002500382100002500407700002200432700002300454856013800477       2006                        frendh  00aLes Coléoptères Scarabaeoidea coprophages (Aphodiidae et Scarabaeidae) de la région d'Essaouira (Sud-Ouest Marocain): inventaire et écologie0 aLes Coléoptères Scarabaeoidea coprophages Aphodiidae et Scarab  a1-220 v2810aAphodiidae10acoprophagous10aEssaouira10ainventory10aPaleartic region10aScarabaeidae10aSouthwestern Morocco1 aFaucheux, Michel, J.1 aMeurgey, Francois1 aWahbi, Youssef, El  uhttps://scarabnet.myspecies.info/les-cole-opte-res-scarabaeoidea-coprophages-aphodiidae-et-scarabaeidae-de-la-re-gion-dessaouira-sud-00656nas a2200181   4500008004100000245010800041210006900149300001000218490000900228653001500237653001300252653001500265653001600280653001700296653001800313100002000331856012300351       2006                        eng d00aA new species of Aphodius Illiger (Coleoptera: Scarabaeidea: Aphodiinae) from the central United States0 anew species of Aphodius Illiger Coleoptera Scarabaeidea Aphodiin  a61-680 v118510aAphodiinae10aaphodius10aCOLEOPTERA10anew species10aScarabaeidae10aUnited States1 aPaulsen, M., J.  uhttps://scarabnet.myspecies.info/new-species-aphodius-illiger-coleoptera-scarabaeidea-aphodiinae-central-united-states02576nas a2200301   4500008004100000245010300041210006900144260000800213300001200221490000700233520168000240653002201920653001101942653002001953653001501973653007901988653001902067653001602086653001102102653001302113653001702126653002502143100002202168700001702190700001302207700001902220856003502239       2006                        eng d00aPrimary dispersal of seeds by primates and secondary dispersal by dung beetles in Tikal, Guatemala0 aPrimary dispersal of seeds by primates and secondary dispersal b  cMay  a390-3970 v383 aWe 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.10aalouatta-palliata10aAteles10aCEBUS-CAPUCINUS10aDEFECATION10aGERMINATION literature review function service seed dispersal mammal value10ahowler monkeys10alos-tuxtlas10aMexico10apatterns10aScarabaeidae10atropical rain-forest1 aPonce-Santizo, G.1 aAndresen, E.1 aCano, E.1 aCuaron, A., D.  u<Go to ISI>://000236766500014 02241nas a2200193   4500008004100000245013000041210006900171260000800240300001200248490000700260520154000267653001401807653001601821653001501837653001701852100002401869700001601893856013801909       2006                        eng d00aComposicao e diversidade de Scarabaeoidea (Coleoptera) atraidos por armadilha de luz em area rural no norte do Parana, Brasil0 aComposicao e diversidade de Scarabaeoidea Coleoptera atraidos po  cmar  a103-1080 v963 a 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. 10adiversity10alight trap.10arural area10aScarabaeidae1 aRonqui, Daniele, C.1 aLopes, Jose  uhttps://scarabnet.myspecies.info/composicao-e-diversidade-de-scarabaeoidea-coleoptera-atraidos-por-armadilha-de-luz-em-area-rural-no-01372nas a2200217   4500008004100000245012400041210006900165300001200234490000800246520061900254653002500873653001200898653001700910653000900927653001400936653001300950653001700963653001500980100002100995856013801016       2006                        eng d00aLaboratory studies on the feeding behavior of the putative dung beetle, Ateuchus histeroides (Coleoptera: Scarabaeidae)0 aLaboratory studies on the feeding behavior of the putative dung   a157-1690 v1143 aAbstract.—Through a series of laboratory feeding trials, it was demonstrated that the putative dung beetle, Ateuchus histeroides Weber (Coleoptera: Scarabaeidae), is a consumer of both vertebrate dung and insect carrion, and that it can produce progeny reared on either of those foods. There was no significant difference between the survival periods of adults maintained on either cow dung or dead insects, but both groups survived significantly longer than a group deprived of food. This is the first documentation of both dung and carrion feeding and subsequent progeny production for a member of this genus. 10aAteuchus histeroides10acarrion10adead insects10aDung10alongevity10aprogeny.10aScarabaeidae10astarvation1 aYoung, Orrey, P.  uhttps://scarabnet.myspecies.info/laboratory-studies-feeding-behavior-putative-dung-beetle-ateuchus-histeroides-coleoptera-scarabaeida
