From the 180 Brazilian bat species (Order Chiroptera), 46,7% can occur in urban areas, although little is known about the influence of these environments on species' ecology, and there are no published works about urban bat community structure in Brazil to date. The urbanization process, however, may potentially lead to important ecological changes on intra and interspecific pathogenic transmissions dynamics in bat communities. Existing urban chiropterofauna surveys come from secondary data from rabies passive surveillance systems, which has been providing evidences about viral circulation on these populations. However, these data do not allow to acknowledge the ecological and epidemiological roles of urban bats using only secondary data. This knowledge is crucial in a context of harmonious coexistence between humans, bats and domestic animals in areas with different levels of anthropization. Thus, the aims of the present work are to perform a bioacustic monitoring on bat communities to investigate how the landscape components influence aspects such as richness and relative abundance of species and the activity degree of these animals on an urban-rural-natural gradient, and access people's atitudes and perception about their coexistence with bats and the potential disease transmission that can come with it.
