| ABSTRACT We describe and illustrate a new species of Coccoloba (Polygonaceae), named Coccoloba gigantifolia, from the Brazilian Amazon. It resembles Coccoloba mollis Casar, but differs from the latter species by its much larger leaves in the fertile branches. The species has only been recorded in the Madeira River basin, in the states of Amazonas and Rondônia, in the central and southwestern Brazilian Amazon. The description was based on herbarium material, cultivated plants, and individual trees in their natural habitat. We provide illustrations, photographs, and an identification key with morphological characteristics that distinguish the new taxon from the other two related taxa of the Coccoloba sect. Paniculatae, as well as comments on the geographic... |

| Abstract Amazonian biodiversity is increasingly threatened due to the weakening of policies for combating deforestation, especially in Brazil. Loss of animal and plant species, many not yet known to science, is just one among many negative consequences of Amazon deforestation. Deforestation affects indigenous communities, riverside as well as urban populations, and even planetary health. Amazonia has a prominent role in regulating the Earth’s climate, with forest loss contributing to rising regional and global temperatures and intensification of extreme weather events. These climatic conditions are important drivers of emerging infectious diseases, and activities associated with deforestation contribute to the spread of disease vectors. This review... |

| ABSTRACT The present study encompasses the species composition and ecological characteristics of the snake community in a Cerrado-Amazon transition zone in Midwest of Brazil (state of Mato Grosso). The data were collected during six excursions to the "Tanguro" (study area) by visual encounter survey, pitfall traps with drift fences and non-systematic sampling. We collected 194 specimens, distributed in 34 species, 26 genera, and eight families. The most abundant species were Crotalus durissus Linnaeus, 1758 (n = 50), Philodryas olfersii (Lichtenstein, 1823) (n = 15), Philodryas nattereri Steindachner, 1870 (n = 13), Xenodon rabdocephalus (Wied, 1824) (n = 12), Lachesis muta (Linnaeus, 1766) (n = 10) and Erythrolamprus almadensis (Wagler, 1824) (n = 10).... |

| ABSTRACT Sphingidae attracted to light were systematically collected in an Amazonian forest canopy. Sampling occurred at a height of 34 m in an upland primary rainforest plateau in the Cueiras River basin, located within the Experimental Station of Tropical Silviculture, Manaus municipality, Amazonas, Brazil. The hawkmoths were collected using a vertical white sheet illuminated by a 250 W mixed mercury light and a 20 W black-light (BLB) fluorescent tube. Monthly collections were carried out from January to December 2004, during three nights of lunar transition from third quarter moon to new moon between 6 p.m. and 6 a.m. We sampled 1748 specimens, represented by 1485 males and 263 females, belonging to 52 species and 21 genera. Xylophanes comprised the... |

| This survey aimed to describe the floristic composition and structure of the epiphytic community occurring in a terra firme forest in the city of Coari, Brazil, in the Amazon region. Data collection was performed with a 1.5 ha plot method, with which upland, slope and lowland habitats were sampled. All angiosperm epiphytes and their host plants (diameter at breast height > 10 cm) were sampled. We recorded 3.528 individuals in 13 families, 48 genera and 164 species. Araceae was the most prevalent family with regard to the importance value and stood out in all related parameters, followed by Bromeliaceae, Cyclanthaceae and Orchidaceae. The species with the highest epiphytic importance values were Guzmania lingulata (L.) Mez. and Philodendron linnaei... |

| Abstract: Despite being the largest and most remarkable species of Chalcidoidea, species of Leptofoeninae are very rarely collected. Here, we expand the distribution range extension of the Leptofoenus howardi (Ashmead, 1895) for Rondônia and Minas Gerais, Leptofoenus stephanoides (Roman, 1920) for Rondônia, Espírito Santo and São Paulo and Leptofoenus westwoodi (Ashmead, 1895) for Roraima, Amazonas, Rondônia, Bahia, Minas Gerais, Rio de Janeiro and Rio Grande do Sul. |
