| O estudo objetivou avaliar a riqueza e composição de vertebrados de médio e grande porte em latrinas ativas e inativas de ariranhas [Pteronura brasiliensis (Gmelin, 1788)], em uma Unidade de Conservação de Uso Sustentável na Amazônia Oriental Brasileira. O estudo foi realizado em 45 latrinas ao longo de 230 km nos rios Falsino e Araguari (0°55'N, 51°35'W), sendo que desse total, 24 apresentaram fezes frescas e 21 fezes velhas de ariranhas. De julho a novembro de 2012, cada latrina foi monitorada com uma armadilha fotográfica programada para operar por 24 horas. O esforço de campo resultou em 458,8 armadilhas/dia, sendo 247,5 armadilhas/dia em latrinas com fezes frescas e 211,3 armadilhas/dia com fezes velhas. Foram obtidos registros de 22 espécies de... |

| Observational and experimental studies have shown that increased concealment of bird nests reduces nest predation rates. The objective of the present study was to evaluate differences in predation rates between two experimental manipulations of artificial ground nests (i.e., clearing an area around the artificial nest or leaving it as natural as possible), and test whether environmental variables also affected nest predation in an undisturbed area of Amazonian forest in eastern Brazil. A generalized linear model was used to examine the influence of five variables (manipulation type, perpendicular distance from the main trail, total basal area of trees surrounding the nest site, understorey density, and liana quantity) on nest predation rates. Model... |

| The varzea forests of the estuary of the Amazon River cover 25,000 km2within the states of Pará and Amapá. The mammals of those forests, especially bats, are still poorly known. Hence, the present study aimed at inventorying the bat species from three localities of a varzea forest in the estuary of the Amazon River. Between November and December 2013, we selected 18 sampling sites in the mouths of three tributaries of the Amazon River: the rivers Ajuruxí, Maracá, and Mazagão. We set up ten mist nets (12 x 3 m) along a 150-m linear transect in each sampling site, in a total sampling effort of 38,888 m2.h. We captured 403 individual bats of 40 species and five families. We recorded the families: Phyllostomidae (n = 31 species), Emballonuridae (n = 6... |

| Standard line-transect census techniques were deployed to generate a checklist and quantify the abundance of medium and large-bodied vertebrate species in forest areas of eastern Amazonia with and without a history of reduced-impact logging (RIL). Three areas were allocated a total of 1,196.9 km of line-transect census effort. Sampling was conducted from April to June 2012 and from April to August 2013, and detected 29 forest vertebrate species considered in this study belonging to 15 orders, 20 families and 28 genera. Additionally, eight species were recorded outside census walks through direct and indirect observations. Of this total, six species are considered vulnerable according to IUCN (Ateles paniscus, Myrmecophaga tridactyla, Priodontes maximus,... |
