During 1993 we monitored three habitats: primary and secondary forest, and open fields used for cattle grazing. A total of 55 295 trap / hours, evenly distributed among the three habitat types, captured 9 115 individuals (18 species, 11 general. There were differences in species richness between habitats (F-2,F-9 = 29.88; P < 0.001), an in number of individuals (F-2,F-9 = 36.22; P < 0.001). Collecting sites differed within habitats. Cluster analyses show that species composition differs between habitats with and without tree cover. Open areas act as barriers for movements of forest species. Differences between habitats and collecting sites may reflect high environmental heterogeneity, land use history of the sites or the influence of nearby disturbance. Some of the species found in open fields come from lower elevations and are usually associated with intense human disturbance. The proportion of digging and rolling: species is similar in both primary and secondary forest, nocturnal species are more abundant; in open areas rolling species are absent and the number of diurnal species increases. We found no relationship between rainfall and species richness (r(2) = 0.26; P = 0.41), nor between rainfall and number of individuals collected throughout the year (r(2) = 0.07; P = 0.84). For all species the number of individuals collected decreased during dry season and during the onset of the rainy season.10aAphodiinae10aColombian Andes10aconsequences10adiversity and conservation10aDung beetles10afragmentation10aheterogeneity10aScarabaeinae10asoil-moisture10aspatial10asuccession gradient1 aEscobar, F.1 ade Ulloa, P., C.  u<Go to ISI>://00016972090002000672nas a2200157   4500008004100000245016700041210006900208300001400277490000700291100001600298700001600314700001300330700001600343700001700359856013800376       2008                        eng d00aTemporal shifts in dung beetle community structure within a protected area of tropical wet forest: a 35-year study and its implications for long-term conservation0 aTemporal shifts in dung beetle community structure within a prot  a1584-15920 v451 aEscobar, F.1 aHalffter, G1 aSolis, A1 aHalffter, V1 aNavarrete, D  uhttps://scarabnet.myspecies.info/temporal-shifts-dung-beetle-community-structure-within-protected-area-tropical-wet-forest-35-year-st02876nas a2200265   4500008004100000245013400041210006900175300000900244490000800253520202500261653001702286653002202303653001802325653001702343653002002360653001702380100001602397700001502413700001602428700001802444700001602462700001502478700001602493856010102509       2007                        eng d00aGlobal dung beetle response to tropical forest modification and fragmentation: A quantitative literature review and meta-analysis0 aGlobal dung beetle response to tropical forest modification and   a1-190 v1373 aAlthough insects are crucial for maintaining ecosystem function, our understanding of their overall response to human activity remains limited. This is no less true of dung-burying beetles (Coleoptera: Scarabaeidae: Scarabaeinae), which provide a suite of critical ecosystem functions and services, yet but face multiple conservation threats, particularly from landscape conversion. Here we use a review and meta-analysis to synthesize the current knowledge concerning response to tropical forest modification and fragmentation of dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae). For every modified habitat type and individual forest fragment across 33 studies, we calculated six dung beetle community parameters, standardized relative to intact tropical forest. We organized modified habitats along an approximate disturbance gradient ranging from selectively logged, late and early secondary forest, through agroforestry, tree plantations, to annual crops, cattle pastures and clear-cuts. Secondary forests, selectively logged forest and agroforests supported rich communities with many intact forest species, while cattle pastures and clear-cuts contained fewer species overall with few forest-dwelling species. Abundance generally declined with increasing modification, but was quite variable. Communities in open habitats were often characterized by hyper-abundance of a small number of small-bodied species, leading to low evenness. Across fragmentation studies, dung beetle species richness, abundance and evenness declined in smaller forest fragments. Richness and abundance sometimes declined in more isolated fragments, although this response appeared to depend on matrix quality. Across both habitat modification and fragmentation studies, geographic location and landscape context appeared to modify dung beetle response by influencing the available pool of colonists. We discuss potential underlying mechanisms and conclude with recommendations for management and conservation and for future research.10aAgroforestry10acommunity ecology10adeforestation10aInvertebrate10aLand-use change10aScarabaeinae1 aNichols, E.1 aLarsen, T.1 aSpector, S.1 aDavis, A., L.1 aEscobar, F.1 aFavila, M.1 aVulinec, K.  uhttp://www.sciencedirect.com/science/article/B6V5X-4ND710H-1/2/3d7a5f4362824647199ebdfd5821fa14
