Resumen
Agroforestry systems are known to reduce impacts of traditional agriculture due to their capacity of decreasing deforestation and maintain biological diversity. This study investigated bat abundance, richness and diversity in an alley cropping system in São Paulo state, comparing bat assemblage to an adjacent forest fragment. Captures occurred in two distinct periods and the sampling effort of 1,296m2/h was applied for each site. From thirteen species captured in the fragment (n=109), in which C. perspicillata, A. lituratus and S. lilium were the most abundant, only two (A. lituratus and S. lilium) were recorded at the alley cropping (n=7). Shannon diversity was also significantly lower for the alley cropping (H?= 0.60), when compared to the forest fragment (H?= 2.02). Contrary to our expectations, the alley cropping system studied here does not support bat richness and diversity, as accomplished by other agroforestry complexes. The results also reinforce the importance of considering wildlife while managing agricultural landscapes and establishing agroforestry systems.
