A case study from Borneo using dung beetles (Coleoptera: Scarabaeoidea) as indicators0 aDoes reducedimpact logging help preserve biodiversity in tropica  a467-4750 v293 aThe 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.10adiversity10aecotone (biological conservation 2007)10aedge effects10amodification10aselective logging1 aDavis, Andrew, J.  uhttps://scarabnet.myspecies.info/does-reduced-impact-logging-help-preserve-biodiversity-tropical-rainforests-case-study-borneo-using-01014nas a2200241   4500008004100000245014400041210007000185260009900255300001000354653001400364653004800378653001800426653001400444653001700458653001700475653001700492100002200509700002300531700003000554700002700584700002300611856013800634       2001                        eng d00aVariación de la diversidad en especies de Scarabaeinae (Coleoptera:Scarabaeidae) como respuesta a la antropización de un paisaje tropical0 aVariación de la diversidad en especies de Scarabaeinae Coleopter  aGuadelajara, MéxicobUniversidad de Guadalajara—Universidad Autónoma del Estado de Morelos  a35-5310acommunity10aconservation (biological conservation 2007)10adeforestation10adiversity10amicroclimate10amodification10aScarabaeinae1 aHalffter, Gonzalo1 aArellano, Lucrecia1 aNavarrete-Heredia, J., L.1 aLopéz, H., E.
