Diversidade de mamíferos e aves cinegéticas na terra do meio
(Universidade Federal do Pará, 2018-02-28) SACCARDI, Victor; HERNÁNDEZ-RUZ, Emil José; http://lattes.cnpq.br/9304799439158425; https://orcid.org/0000-0002-3593-3260
Studies on species abundance are critical to understand the patterns and responses of communities to everlasting effects, like climate change, or transient disturbances, like hunting and deforestation. Millions of people in tropical forests depend on wildlife to ensure their protein intake and their food security. Terra do Meio is located in Pará state, Brazilian Amazon, in the watershed of the middle Xingu river, composing a group of protected areas that receive great deforestation pressure, where traditional indigenous and riverside populations live. In order to describe the diversity of medium and large mammals and game bird species of three Conservation Units, 835 km were covered in nine transects. Comparisons were also made between the areas, ascertaining the impacts of hunting, and proposed recommendations for the monitoring of the biodiversity. Population estimates of the species were obtained by the Distance Sampling method. Indirect data were also collected and camera traps also installed. 47 species were recorded. The results suggest that hunting does not drastically affect wild populations in the area and may indicate that local hunting currently tends to be sustainable. This study reinforces the importance of extensive areas for the maintenance of viable populations and the sustainability of hunting in these regions. This study presents estimates of species density in these areas, and it provides the first information on the diversity of mammals and game birds of Riozinho do Anfrísio Extractive Reserve.

Eastern extension of the geographic range of Mico emiliae
(Instituto Nacional de Pesquisas da Amazônia, 2018-09) ANDRADE, Roberto Portella de; MOURTHÉ, Ítalo Martins da Costa; SACCARDI, Victor; HERNÁNDEZ-RUZ, Emil José
The distribution of the callitrichids inhabiting the Tapajós-Xingu interfluvium is still poorly understood, probably because of the limited number of studies in this remote region. Mico emiliae is a callitrichid endemic to Brazil, occurring between the Jamanxim and Teles Pires rivers, and Serra do Cachimbo in the west and Iriri River in the east, in the states of Pará and Mato Grosso. However, its current distribution is still uncertain. After ca. 430-km surveys in Serra do Pardo National Park, we successfully confirmed the occurrence of this species for the first time approximately 180 km east of its previously known eastern limit in Pará. Our records expand the distribution of M. emiliae to the left bank of the Xingu River, increasing the known extent of its occurrence by 83%.
