Deforestation causes the formation of forest fragments and edges, changing the biotic and abiotic conditions of a forest ecosystem. The edge effects in a forest can be assessed by soil indicators. The objective of this study was to evaluate the litter stock and arbuscular mycorrhizal fungal community as edge effect indicators in a fragment of a seasonal forest in Vitória da Conquista, Bahia state. Sampling was carried out at the end of each season. Four sampling ranges were established in the edge-interior direction (edge: 0–10 m, range 1: 40–50 m, range 2: 80–90 m, and interior: 400 m). The accumulated litter was collected four times using a wooden template (area 0.25 m2). The soil samples (layer 0–5 cm) for extracting the spores of mycorrhizal fungi were collected from the same litter collection areas. The edge effect in areas of a seasonal forest can change the litter stock, showing a mass reduction closer to the edge. The community of mycorrhizal fungi shows the occurrence of unique species in the gradient of edge-interior fragment.
