RESUMO

Habitat fragmentation alters the dynamics of tropical tree assemblages, being able to modify the dung beetles communities. The objective of this research was to determine how the fragments metrics and functional attributes of trees assemblages influence the dung beetles communities in Atlantic forest fragments of northeastern Brazil. The collecting of dung beetles was performed from September 2007 to March 2008 using pitfall traps and fly interception traps. A total of 5907 individual dung beetles from 29 species were captured during this study. The specie Dichotomius sericeus was the most abundant, with 67.1 % of total individuals. Among the metrics of the fragments, the size and the isolation of the fragments had effect on the richness of beetles. For attributes of assemblages of trees, the percentage of shade-tolerant trees and wealth of trees influenced the richness of dung beetles. However, the abundance of dung beetles was only influenced by the percentage of shade-tolerant trees. We suggest the conservation of the fragments through the minimization of human impact and efficient guidelines which serve to optimize the future perspectives of trees assembleges and the dung beetles communities
