The saproxylophagous beetles studied can be differentiated according to their presence in three distinct microhabitats of rotting logs: underbark, sapwood - heartwood and microhabitat generalists. Over the 2-year study period, 12 passalid species were recorded (six Passalini and six Proculini) represented by a total of 2971 individuals, collected from 234 rotting logs. The rarefaction method, the lognormal species - abundance relationship, and the nonparametric jackknife method were used to compare species richness between the habitats. The data were also fitted to log series, truncated lognormal, geometric, and broken-stick species abundance models to detect changes in community structure. The community composition of Passalidae in Los Tuxtlas did not differ ostensibly between the primary and secondary forests. Neither the mean number of individuals nor the biomass per log differed significantly. Furthermore, there were no significant differences between the two habitats in terms of the number of underbark, sapwood/heartwood, and microhabitat generalist species. Different richness estimators indicated that the primary forest community is only slightly richer. The slight decrease in richness of the secondary forest is related to a decrease in dominance by certain species, as well as to a more balanced abundance distribution, which is adequately described by the broken-stick model. Complementary explanations for this pattern may be: ( 1) that logging reduces the abundance of dominant species, thus preventing competitive exclusion in the secondary forest; and ( 2) that passalid diversity is not regulated by the diversity of tree species.10aforest change biodiversity dung beetles1 aCastillo, M., L.1 aLobo, J., M.  u<Go to ISI>://00022021350000202230nas a2200169   4500008004100000245012100041210006900162260000800231300001200239490000700251520155400258653004401812100002301856700002201879700002101901856013801922       2006                        eng d00aBeetle species' responses suggest that microclimate mediates fragmentation effects in tropical Australian rainforest0 aBeetle species responses suggest that microclimate mediates frag  cJun  a458-4700 v313 aDespite the enormous contribution of invertebrates to global biodiversity and ecosystem function, the patterns and causes of insect responses to tropical rainforest destruction and fragmentation remain poorly understood. We studied the responses of beetles to these factors in a fragmented upland rainforest landscape in north-east Queensland, Australia. Beetles were sampled using flight interception traps from six replicate sites in rainforest interior, rainforest edge, small rainforest remnants and pasture, interspersed across about 600 km(2). Beetles from 10 family/subfamily groups were sorted to species. There were three major findings. First, converting rainforest into pasture has a very strong negative effect on beetle diversity and species composition. Very few beetle species were present in pasture and none of the most abundant species was more abundant in pasture than rainforest. Second, beetle assemblages appeared to respond to climate. Beetle species composition in drier rainforest habitats was different from that of moister rainforest and there were species unique to each rainforest type. Third, beetle species composition differed between small remnants and interior rainforest: drier-associated species were more abundant in small remnants, whereas wetter-associated species were more abundant in interiors. Edges tended to be intermediate. We argue that this pattern can be attributed to a fragmentation effect mediated by differences in microclimate rather than by floristic, structural, or area and isolation effects.10aforest change biodiversity dung beetles1 aGrimbacher, P., S.1 aCatterall, C., P.1 aKitching, R., L.  uhttps://scarabnet.myspecies.info/beetle-species-responses-suggest-microclimate-mediates-fragmentation-effects-tropical-australian-rai01319nas a2200169   4500008004100000245009100041210006900132260001100201300001200212490000800224520077700232653004401009100002101053700002401074700001701098856003401115       1992                        eng d00aThe Response of Some Rain-Forest Insect Groups to Logging and Conversion to Plantation0 aResponse of Some RainForest Insect Groups to Logging and Convers  cMar 30  a425-4360 v3353 aData and analyses from pilot studies in the Danum area of Sabah, East Malaysia, and elsewhere in the Indo-Australian tropics are used to measure the effects of logging and other human disturbance, such as conversion to plantation, on insect diversity. The two insect groups studied have very different trophic requirements: moths, with floristically specific herbivory, and dung and carrion beetles, exploiting resources of much more uniform quality over different forest systems. Moths show significant loss of diversity and taxonomic quality with disturbance and conversion to plantation. The beetles show much less change in diversity and faunistic composition. The implications for conservation of biodiversity are discussed, and suggestions for further work are made.10aforest change biodiversity dung beetles1 aHolloway, J., D.1 aKirkspriggs, A., H.1 aKhen, C., V.  u<Go to ISI>://A1992HN4610001101523nas a2200217   4500008004100000245008900041210006900130260000800199300001000207490000700217520088500224653004401109100001801153700001501171700002001186700001601206700001701222700001901239700001301258856003401271       2002                        eng d00aA framework for assessment and monitoring of arthropods in a lowland tropical forest0 aframework for assessment and monitoring of arthropods in a lowla  cMay  a43-530 v763 aBy applying principles of adaptive management, and by using the valuable information that arthropods provide from assessment and monitoring programs, managers can identify and reduce possible impacts on biodiversity in development projects. In 1996, the Smithsonian Institution's Monitoring and Assessment of Biodiversity program worked together with Shell Prospecting and Development Peru to establish an adaptive management program to protect biodiversity in a natural gas exploration project in a Peruvian rainforest. In this paper, we outlined the conceptual steps involved in establishing an assessment and monitoring program for arthropods, including setting objectives, evaluating the results and making decisions. We also present the results of the assessment using some of groups of arthropods, and summarize the steps taken to identify appropriate groups for monitoring.10aforest change biodiversity dung beetles1 aFinnamore, A.1 aAlonso, A.1 aSantisteban, J.1 aCordova, S.1 aValencia, G.1 aDe La Cruz, A.1 aPolo, R.  u<Go to ISI>://00017521360000301651nas a2200169   4500008004100000245012800041210006900169260000800238300001200246490000800258520108400266653004401350100002201394700001601416700001501432856003401447       2004                        eng d00aComparison of Coleoptera assemblages from a recently burned and unburned black spruce forests of northeastern North America0 aComparison of Coleoptera assemblages from a recently burned and   cAug  a583-5920 v1183 aSeveral insect groups have adapted to fire cycles in boreal forests, and can efficiently use new habitats created by fire. Our study aimed at producing a first characterization of post- fire Coleoptera assemblages of black spruce forests of eastern North America. For two years, we sampled Coleoptera using flight-interception traps in burned stands of contrasting age and structure in a 5097-ha wildfire and in neighbouring unburned mature stands. More than 40 species were exclusively captured in burned stands. Time elapsed since fire and proximity of unburned forests were the most significant parameters affecting Coleoptera assemblages. Stand age and structure had limited effects on assemblage structure; the Scolytid Polygraphus rufipennis Kirby was the only common species to clearly favor older stands. Fire-associated Coleoptera assemblages found in our study area were clearly distinct from those found in similar unburned stands; we should thus be conservative in our management approach concerning recently burned stands.
