Diversidade de morcegos em unidades de conservação na Amazônia

Author(s): SANTOS, Tamily Carvalho Melo dos
Summary: This study represents the first systematic survey of mammals in three conservation units in Central Amazonia. Thirty-six species were recorded in the Jutaí River Extractive Reserve, 33 in the Jutaí-Solimões Ecological Station and 56 species in the Auatí-Paraná Extractive Reserve. Although the fauna of bats is among the richest mammals in the Amazon, we observed that the Auatí-Paraná Extractive Reserve is the only locality sampled in the Solimões-Japurá interflow. We also observed that the Jutaí River Extractive Reserve and the Jutaí-Solimões Ecological Station, in addition to the Serra do Divisor National Park are the only sites sampled for bats in Brazil. This demonstrates how fragmented the knowledge of Amazon bats is. Estimates using the Jackkinfe 2 estimator indicate that we sampled just over 56%, 59% and 63% of the expected species, respectively. Regarding the composition of the species of Amazonian assemblages, in the clusters it was possible to observe that the sites tend to correspond to the groups: East and West of the Amazon and Guianas region. With the units of this study grouped in the West region, and the Carajás FLONA in the eastern region, as expected. The clustering of the sites analyzed was not related to their proximity, which may be due to the high beta-diversity in the biogeographic scale.We also present the study on the potential distribution of Vampyrode caraccioli through the use of Species Distribution Modeling. The results showed that the species V. caraccioli is more likely to occur in the Amazon and Atlantic Forest biomes. According to the model, the species occurs, preferably, in areas where primary productivity is high, and where annual mean precipitation and leaf vegetation index have intermediate values
