SUMMARY:

Soundscape studies has becoming more popular nowadays as an important tool with the potential to evaluate environmental health, changes in land use, climate change, in several temporal and spatial scales. In tropical environments, the high biodiversity associated with a restricted taxonomic knowledge for many taxa and the lack of financial resources make the acoustic ecology studies more challenging than in other regions. At the same time, tropical areas are the most important in terms of biodiversity conservation, and the use of acoustic monitoring is even more relevant once it can facilitate long-term studies at a lower cost than traditional ecological surveys. Facing a reality of rapid technological innovations and data analysis methods in the acoustic ecology field, this thesis has the main goal of evaluate the use of passive acoustic monitoring in Brazilian biomes, providing analysis protocols and contributing to advance of acoustic ecology in tropical regions. The thesis is divided in three chapters and an appendix with other production non-related to the thesis. In the first chapter we describe patterns in use of acoustic space in a Caatinga area by clustering multiple acoustic indices. During dry season, wind was predominant in the recordings, while in rainy season, was biophony. Daily variations included the birds and wind occupying the acoustic space during the day, while insects predominated at night. In the second chapter, also in a Caatinga area, we aimed to understand how a windfarm facility modifies the soundscape around it. We’ve found that biophonic activity increases as we move closer to the turbines, suggesting that both birds and insects have their acoustic activity patterns modified in response to wind turbines presence. In the third chapter, we used data from Caatinga, Cerrado and Atlantic Forest, to teste whether single indices are able to predict bird species richness and if a composition of several indices allow discrimination of different species’ composition. We’ve found that single indices performance is variable among habitats, and features of birds’ communities as predominance of species and frequency bands used may be affecting the indices results. Even so, a combination of indices was able to distinguish among biomes.
