Preliminary survey of the mammalian fauna in the Anajás-Muaná region, Marajó Island, Pará State, Brazil

Abstract

A short inventory of the mammalian fauna occurring in an area of the Marajó Island was performed during the rainy season. In addition to captures by using Sherman and Tomahawk traps, and mist-nets, indirect evidence was considered, e.g. finding of body fragments of specimens, vocalization, and testimonies from local people. A total of 57 species (22 families) was recorded. None of them is presently considered as critically endangered according to the IUCN criteria. First confirmed record for the fruit-eating bat Platyrrhinus brachycephalus (Rouk & Carter, 1972) in the Marajó archipelago. Additional surveys conducted in both wet and dry seasons are required for improving the profile of richness and diversity of mammal species in that region.
