The four habitats had similar richness, species composition, and assemblage structure of dung and carrion beetles. Differences were found in abundance and biomass levels for the four dominant species in the landscape. Dung beetles were more abundant than carrion beetles, but the biomass was higher for the latter. Carrion beetles were seasonal, while dung beetles were clearly not. When forest fragments and shade coffee plantations were compared to other similar habitats in the region, the same general pattern was observed. However, forests with high disturbance and monospecific shade coffee plantations had lower species richness than forests with low and medium disturbance and polyspecific shade coffee plantations. Thus shade coffee plantations maintain connectivity between patches of cloud forest in a landscape that is strongly affected by human activities. Protecting landscape diversity appears to ensure high species richness.10aanthropogenic change10abiodiversity10acarrion beetles10adung beetle10afragmentation10amodification (biological conservation 2007)10ashade coffee plantations10atropical montane cloud forest10aVeracruz1 aArellano, Lucrecia1 aFavila, Mario, E1 aHuerta, Carmen  uhttps://scarabnet.myspecies.info/diversity-dung-and-carrion-beetles-disturbed-mexican-tropical-montane-cloud-forest-and-shade-coffee-02351nas a2200253   4500008004100000245012500041210006900166260000800235300001200243490000700255520156400262653002501826653001701851653001801868653002201886653001401908653001501922653002501937100002901962700002601991700001902017700002702036856003402063       2005                        eng d00aDung beetle community (Coleoptera : Scarabaeidae : Scarabaeinae) in a tropical landscape at the Lachua Region, Guatemala0 aDung beetle community Coleoptera Scarabaeidae Scarabaeinae in a   cApr  a801-8220 v143 aBiological diversity conservation within natural reserves has been prioritized, but conservation efforts outside protected areas (where most human activities take place) have been very little considered. In this scenario, an alternative agricultural practice that may reduce the impacts of fragmentation in outer landscapes is a perforation process, which involves conservation in agricultural fields surrounded by continuous forests. Such practices enhance the positive impact of ecological services on fields. In this study we analyzed the biological diversity state in perforation fields and their surrounding forests. The analysis was done using dung beetles as biological indicators. A nested pattern in dung beetles distribution was found, which ordered the surrounding continuous forest sites as the ones with the highest species richness, followed by the perforation fields, and placed the fragmentation practice fields (continuous agricultural fields surrounding forest patches) with the lowest one. Indicator species for perforation fields and surrounding continuous forests were chosen. In general, perforation practice fields differed in composition, based upon functional groups richness and identity; it also contained a higher species richness than the fragmentation practice. Agricultural practices that enhance biological diversity conservation such as perforation, should be recommended and considered in natural resource management by local communities in order to take advantage of ecological services that otherwise may be gradually lost.10abiological diversity10aDung beetles10afragmentation10afunctional groups10alandscape10anestedness10aperforation practice1 aAvendano-Mendoza, Carlos1 aMoron-Rios, Alejandro1 aCano, Enio, B.1 aLeon-Cortes, Jorge, L.  u<Go to ISI>://00022850380000202473nas a2200349   4500008004100000245012300041210006900164260000800233300001200241490000700253520148700260653002201747653001501769653001601784653001301800653001801813653001601831653001101847653002401858653001901882653001901901653002901920653001701949653001701966653002201983653002502005100001402030700001502044700001602059700001302075856003502088       2005                        eng d00aDiversity of dung-beetle community in declining Japanese subalpine forest caused by an increasing sika deer population0 aDiversity of dungbeetle community in declining Japanese subalpin  cMar  a135-1410 v203 aThe Ohdaigahara subalpine plateau in Japan has recently suffered a reduction in primary forest land caused by an increasing population of sika deer (Cervus nippon). Deer have debarked many trees, causing die-back, gradually changing the primary forest first to light forest with a floor that is densely covered with sasa grass (Sasa nipponica) and then to S. nipponica grassland. To examine the effects of vegetative transformation on the dung-beetle community, we compared the diversity and abundance of dung-beetle assemblages in the primary forest, transition forest, and S. nipponica grassland using dung-baited pitfall traps. The species richness and species diversity (Shannon-Wiener index) were significantly highest in the primary forest and lowest in the S. nipponica grassland. The evenness (Smith-Wilson index) was highest in the primary forest and nearly equal in the transition forest and S. nipponica grassland. The abundance was apparently greater in the transition forest than in the primary forest and S. nipponica grassland. These results suggest that loss of primary forest resulting from an increasing deer population decreases the diversity of the dung-beetle community while increasing the abundance of dung beetles in the transition forest. Sika deer use transition forests and grasslands more frequently than primary forests as habitat, but an increase in dung supply there does not necessarily increase the diversity or abundance of dung-beetle assemblages.10aalouatta-palliata10aCOLEOPTERA10adung beetle10aevenness10afragmentation10alos-tuxtlas10aMexico10aohdaigahara mammals10aprimary forest10asasa nipponica10aSasa nipponica grassland10aScarabaeidae10asouth-africa10atransition forest10atropical rain-forest1 aKanda, N.1 aYokota, T.1 aShibata, E.1 aSato, H.  u<Go to ISI>://000228011500004 04086nas a2200181   4500008004100000245008000041210006900121300001400190490000700204520354300211653001603754653001803770653002203788653001103810100001903821700001803840856004603858       2005                        eng d00aEffects of Forest Fragmentation on a Dung Beetle Community in French Guiana0 aEffects of Forest Fragmentation on a Dung Beetle Community in Fr  a1103-11120 v193 aAbstract: Fragmentation is the most common disturbance induced by humans in tropical forests. Some insect groups are particularly suitable for studying the effects of fragmentation on animal communities because they are taxonomically and ecologically homogenous. We investigated the effects of forest fragmentation on a dung beetle species community in the forest archipelago created in 1994-1995 by the dam of Petit Saut, French Guiana. We set and baited an equal number of pitfall traps for dung beetles on three mainland sites and seven island sites. The sites ranged from 1.1 to 38 ha. In 250 trap days, we captured 50 species in 19 genera. Diversity indices were high (2.18-4.06). The lowest diversity was on the small islands and one mainland site. Species richness and abundance were positively related to fragment area but not to distance from mainland or distance to the larger island. The islands had lower species richness and population than mainland forest, but rarefied species richness was relatively invariant across sites. There was a marked change in species composition with decreasing fragment that was not caused by the presence of a common fauna of disturbed-area species on islands. Small islands differed from larger islands, which did not differ significantly from mainland sites. Partial correlation analyses suggested that species richness and abundance of dung beetle species were positively related to the number of species of nonflying mammals and the density index of howler monkeys (Alouatta seniculus), two parameters positively related to fragment area. Efectos de la Fragmentacion de Bosques sobre una Comunidad de Escarabajos Coprofagos en La Guyana Francesa Resumen: La fragmentacion es la mas comun de las perturbaciones inducidas por humanos en bosques tropicales. Algunos grupos de insectos son particularmente adecuados para estudiar los efectos de la fragmentacion sobre comunidades animales porque son taxonomica y ecologicamente homogeneos. Investigamos los efectos de la fragmentacion de bosques sobre una comunidad de especies de escarabajos coprofagos en el archipielago de bosque creado en 1994-1995 por la presa de Petit Saut, Guyana Francesa. Colocamos y cebamos el mismo numero de trampas para escarabajos coprofagos en tres sitios continentales y siete sitios insulares. Los sitios variaron entre 1.1 y 38 ha. En 250 dias-trampa, capturamos 50 especies en 19 generos. Los indices de diversidad fueron altos (2.18-4.06). La menor diversidad ocurrio en las islas pequenas y en un sitio continental. La riqueza y abundancia de especies se relacionaron positivamente con el area del fragmento pero negativamente con la distancia al continente o a la isla mas grande. Las islas tuvieron menor riqueza de especies y tamano poblacional que el bosque continental, pero la riqueza de especies rarificada fue relativamente invariable en todos los sitios. Hubo un cambio notable en la composicion de especies con la disminucion del fragmento que no se debio a la presencia de una fauna comun de especies de areas perturbadas en las islas. Las islas pequenas difirieron de islas mas grandes que no difirieron significativamente de los sitios continentales. Los analisis de correlacion parcial sugirieron que la riqueza y abundancia de especies de escarabajos coprofagos se correlacionaron positivamente con el numero de especies de mamiferos no voladores y con el indice de densidad de monos aulladores (Alouatta seniculus), dos parametros que se relacionan positivamente con el area del fragmento.10adung beetle10afragmentation10alago guri mammals10amammal1 aFeer, Francois1 aHingrat, Yves  uhttp://www.blackwell-synergy.com/loi/cbi 00666nas a2200169   4500008004100000245012800041210006900169300001400238490000800252653001300260653001800273653001100291653001200302100001700314700002700331856013800358       2005                        eng d00aAnthropogenic determinants of primate and carnivore local extinctions in a fragmented forest landscape of southern Amazonia0 aAnthropogenic determinants of primate and carnivore local extinc  a383–3960 v12410aAmazonia10afragmentation10amammal10amammals1 aMichalski, F1 aPeres, CA., . . 124: .  uhttps://scarabnet.myspecies.info/anthropogenic-determinants-primate-and-carnivore-local-extinctions-fragmented-forest-landscape-south00877nas a2200253   4500008004100000245010600041210006900147300001200216490000700228653004800235653001700283653001600300653001700316653001800333653001100351653001500362653002100377653001300398100002000411700002000431700002300451700002200474856012700496       2005                        eng d00aFrog, Bat and Dung Beetle Diversity in the Cloud Forest and Coffee Agroecosystems of Veracruz, Mexico0 aFrog Bat and Dung Beetle Diversity in the Cloud Forest and Coffe  a400-4100 v1910aagroforestry (biological conservation 2007)10acloud forest10aDisturbance10aDung beetles10afragmentation10aMexico10amulti-taxa10apolyagroforestry10aVeracruz1 aPineda, Eduardo1 aMoreno, Claudia1 aEscobar, Frederico1 aHalffter, Gonzalo  uhttps://scarabnet.myspecies.info/frog-bat-and-dung-beetle-diversity-cloud-forest-and-coffee-agroecosystems-veracruz-mexico00758nas a2200217   4500008004100000245009800041210006900139300001400208490000700222653001100229653001600240653001700256653005100273653001800324653001000342653001100352653001300363100002100376700001800397856012500415       2005                        eng d00aRapid recovery of dung beetle communities following habitat fragmentation in Central Amazonia0 aRapid recovery of dung beetle communities following habitat frag  a3303-33110 v8610abrazil10aDisturbance10aDung beetles10afaunal collapse (biological conservation 2007)10afragmentation10aklein10amanaus10arecovery1 aQuintero, Ingrid1 aRoslin, Tomas  uhttps://scarabnet.myspecies.info/rapid-recovery-dung-beetle-communities-following-habitat-fragmentation-central-amazonia
