<br/><br/> <br/><br/>ABSTRACT<br/><br/>The aim of this study was to evaluate the edge effect using the macrofauna community of the<br/>soil as indicator in three fragments of Semi-deciduous Seasonal Forest in the city of Vitória da<br/>Conquista, Bahia, Brazil. Three sampling ranges denominated edge, transition and interior were<br/>delimited in each fragment. The macrofauna community was sampled at two seasons of the year<br/>(dry and wet). Monoliths were collected from soil at 10 cm depth in each range. The density and<br/>richness of the fauna, as well as the Shannon diversity index and the Pielou equitability index,<br/>were calculated. It was observed that the edge effect is expressed from the presence/absence of<br/>orders of individuals in the different fragment ranges, with no interference in the density, average<br/>wealth or number of individuals in each group. The edaphic community presents higher density<br/>and average richness in the dry period within the transition and interior range of the fragments.<br/><br/>Keywords: fragmentation, density, richness.
