Tradition vs. innovation: comparing bioacoustics and mist-net results to bat sampling

Bats are a complex and diverse group, making their study remarkably challenging. Several methods allow the of bats, e.g. mist-nets acoustic monitoring (AM). We compare use AM to inventory bats in mountainous region São Paulo state, Brazil. provide species list for area based on registered with both methodologies, comparing known obtained from literature. calculated beta diversity between methodologies evaluate dissimilarity composition sampled these methods. also performed PCA if bat fauna showed species-habitat associations. recorded 15 species/sonotypes through 22 mist-nets. Beta revealed 97% composition. The turnover component explained 96% this dissimilarity. that Vespertilionidae were associated border/cluttered habitats, while Molossidae present all habitat types. state comprises eighty species. Our more than 25% fauna. Mist-nets efficient sampling low-flying/low-intensity echolocating bats. is crucial high-flying/high-intensity This second state.
