Resumen
Landscape composition and heterogeneity are considered important factors for enhancing biodiversity and their associated ecosystem services in human-modified landscapes. Despite their roles in pest suppression in agricultural areas, insectivorous bats have been poorly represented in studies assessing the effects of landscape structural changes, particularly in the Neotropics. We evaluated how the composition and heterogeneity of the landscape, at several spatial scales, influenced the diversity and activity of aerial insectivorous bats in organic vineyards. Bat activity was quantified using acoustic surveys at 16 vineyards distributed across the central zone of Chile, where landscape composition and heterogeneity were determined by spatial analysis (GIS). Data were analyzed using partial least square regressions (PLS). The diversity and activity of aerial insectivorous bats in vineyards increased with the compositional and configurational heterogeneity of the lands
