Notas preliminares sobre os morcegos do Parque Nacional da Amazônia (Médio Tapajós)

Abstract

A Study on "bats was made at the Amazon National Park located partly in the state of Para and partly in Amazonas. This Park has an area of 1.000.000 ha. The objectives of the study were to make a survey of the species that exist there and to collect data about their distribution and ecology. Bird nets of 120 to 180 m2 were used to capture the bats; in 10 different places within the accessible area of the Park. One hundred and thirty three individuals of 17 species of 5 families were captured; 11 species from the family Phillostomidae. Carollia is the most common genus. It was concluded that the coexistence of so many different species in a single area is possible because of the diversity in feeding habitat. Frugivorous bats were the most commonly collected but insectivorous, nectivorous and sanguivorous bats were also found. The bat fauna of Manaus, the National Parque of Amazônia, and Belem were compared. Only 11% of the species were found to be in common to the three localities. The fauna of the Park showed greater affinity to that of Manaus than Belem.
