The bat fauna of the Kararaô and Kararaô Novo caves in the area under the influence of the Belo Monte hydroelectric dam, in Pará, Brazil.

Brazil's large territory displays significant richness in caves with about 12 thousand caves already recorded. Nevertheless, studies on bats in these environments are extremely scarce and fragmented. This study characterized the chiropteran fauna from two sandstone caves under the influence of the Belo Monte hydroelectric dam (Belo Monte UHE) in Pará, Brazil.
