	abstract = {The Amazon Basin can be divided into two geomorphological regions based on the age of its soils: young (< 30 mya) and old (> 300 mya). We tested the effects of soil age on dung beetle communities by comparing biomass, abundance, and species between reserves in Ecuador on young soils and reserves in Brazil on old soils. Beetle biomass in the old Amazon was one-third that in the young Amazon, and beetle abundance in the old Amazon was one-fourth that in the young Amazon. Species richness, rarefied to equal sample sizes, was not significantly different between old and young soils. These data suggest young soils of the Amazon support a significantly greater biomass and abundance of dung beetles than old soils, but that species richness across the Basin is similar. As dung beetles are bio-indicators of mammals, our data support previous studies indicating a greater biomass of mammals on young versus old Amazon soils. },

	abstract = {Arboreal foraging by dung beetles has been reported from tropical rainforests in several regions. In the central Amazon, Brazil, the widespread, arboreal dung beetle Canthon subhyalinus Harold was caught most often in dung traps at 8{\textendash}24 m above the forest floor, below the height of most primate activity in the area, where dung should be plentiful yet competition for it low. Studies of dung beetle diversity routinely only include traps set on the forest floor, missing arboreal species such as C. subhyalinus, and generating misleading descriptions of dung beetle diversity and abundance. Future studies of dung beetle diversity should include arboreal traps to accurately sample the diversity and abundance of species that rarely forage at ground level. },
