Living and lost mammals of Rio de Janeiro's largest biological reserve: an updated species list of Tinguá

Mamíferos atuais e extintos na maior Reserva Biológica do Rio de Janeiro: uma lista atualizada de espécies do Tinguá

Abstract:

The Tinguá Biological Reserve (TBR) is the largest protected area of this category in Rio de Janeiro state. Here, for the first time, we present the historical composition of terrestrial mammals' assemblage of TBR region. An inventory was conducted using transect surveys, nonstandard transects, survey of museum specimens and informal reports. Considering all the data, eighty-five species were recorded, placing TBR as the second one in the number of mammals recorded in "Serra do Mar" ecoregion of Atlantic Forest and in the Rio de Janeiro state. Among the species with historical records are the jaguar (Panthera onca) and the golden-lion-tamarin (Leontopithecus rosalia) while the current presence of the maned wolf (Chrysocyon brachyurus) was recorded for the first time. Priority studies should focus on Chiroptera, Rodentia and Didelphimorphia orders, especially in the most remote areas of the reserve, and long-term surveys of endangered species. Besides hunting, fragmentation of its interior by roads, pipelines and transmission lines and exotic species, TBR is also threatened by the urban growth around it and the pressure to reduce its area and its protection category, demanding greater attention by the high levels of governance of protected areas in Brazil.
