ABSTRACT
Abstract In order to evaluate the impact of oil palm cultivation on dung beetles in the eastern Brazilian Amazon, comparisons were made of communities in oil palm plantations and native forest. Pitfall traps baited with human feces were buried to soil level in plantations and surrounding forests. Fifty traps were used in each type of vegetation, placed at 50 m intervals along five transects. Dung beetle communities in oil palm plantations have lower species richness (18 spp.) than in surrounding tropical rainforest (48 spp.), as well as altered species composition. Total abundance of individuals was not significantly different between the two habitats, but species composition was greatly different. Species evenness was greater in the forest. Forest corridors for the preservation of dung beetle species may need to be much wider than current designs. The erosion of biodiversity in dung beetles due to oil palm monoculture parallels what has been seen in other animal taxa in tropical tree plantations.
