Abstract

The aim of this study was to compare the dung beetle (Coleoptera, Scarabaeidae: Scarabaeinae) community structure at two sites in the Charles Darwin Ecological Refuge in Igarassu, Pernambuco, Brazil. Dung beetles were collected in 2006 using monthly samples from 48 pitfall traps baited with human dung and bovine carrion. The dung beetle communities from the study sites were compared in terms of abundance, species richness, and diversity (Shannon index). Seasonality was analyzed by Spearman correlation between rainfall data and community parameters. In total, 2,560 individuals belonging to 40 species, 16 genera, and 6 tribes were collected. Species richness was higher for the clear-cut area compared with the forest habitat. Estimators of species richness suggested a total richness of 42–47 species in the entire study area. A positive correlation was observed between monthly rainfall and total abundance of individuals for the clear-cut area but not for the forest habitat. This study contributes to a better understanding of Scarabaeinae ecology in the Atlantic rainforest of northeastern Brazil.
