| The hypothesis that forest disturbance is important for the recruitment of the large arborescent palms Attalea maripa was tested with a natural experiment in the Pinkaití site (7º 46'S; 51º 57'W), a seasonally-dry Amazonian forest. A 8,000 m long trail, that crosses, in its lower half, an open forest along the Pinkaití stream bottomlands and, on its upper half, a dense forest on a hill, was divided in 160 0.15 ha (50x30 m) sampling units. At each unit, adult palms were counted and percentage of canopy openness was measured with a concave spherical densiometer. The palms were nearly five times more abundant at the bottomlands, whose forest had a canopy 14.8% more open than that of the hill; supporting the hypothesis that disturbance is important for their... |

| Stingrays of the Potamotrygonidae family are a singular group of Neotropical ichthyofauna. Although ancient reports exist about the group, there are still many questions that need to be clarified, such as the biology of the species that occur in the Paraná-Paraguay River system. In the present work, the diet of Potamotrygon falkneri and Potamotrygon motoro, captured in the Upper Paraná River, downstream from the Engenheiro Souza Dias Hydroelectric Power Station (UHE Jupiá), was analyzed. Both species showed a diversified diet, consisting of 14 food items, including Mollusca, Crustacea, Insecta and fish, with the predominance in diversity and abundance of aquatic insects. Only one individual of each species ingested fish. Potamotrygon motoro consumed mainly... |

| This study identified patterns of geographic distribution of 102 Leguminosae taxa within the Park, based on literature data and herbarium specimens. Among the taxa, 38 grow exclusively in CamposRupestres (rocky fields) and 49 in the Semideciduous Forest. Eleven patterns of geographic distribution were identified, of which the West-East-Central South America pattern was the most representative, with 27 taxa. Of the 102 sampled taxa of Leguminosae, five are endemic to the Espinhaço Range and ten are included in lists of endangered species of the flora of Brazil and Minas Gerais. Information on these taxa is crucial to provide conservation practices for conserving the vegetation formations of the PEIT. |

| This paper presents a review of the geographical distribution of Chiasmocleis albopunctata (Boettger, 1885), based on data from literature, scientific collections, and field notes. Our reviewing significantly enlarges the distribution of the species within the Brazilian territory, with new records for the states of Bahia, Maranhão, and Tocantins. Among all species of the genus, C. albopunctata can be considered the one with the widest latitudinal and altitudinal ranges, as well as greater environmental plasticity. |

| Abstract Accurate distributional information is crucial for studies on systematics, biodiversity and conservation. To improve the knowledge regarding the geographical distribution of Omalonyx in South America, we present updated information based on data from a literature review, institutional collections and malacological surveys. All this information composed the dataset used to predict species distribution employing the Maximum Entropy Algorithm (MaxEnt). The model was run using data on species distribution, altitude and bioclimatic variables (WorldClim database). The model had consistent performance, and areas presenting similar conditions to areas where the species were recorded were considered areas of occurrence. The predicted occurrence areas... |

| Neste trabalho foi realizado o primeiro levantamento da macrofauna de fital da ilha da Queimada Pequena, focalizando o registro das espécies de moluscos, crustáceos e equinodermos associados a Sargassum spp. Para a amostragem da macrofauna associada, foram coletadas aleatoriamente 6 frondes de Sargassum localizadas a 6 m de profundidade, usando-se equipamento de mergulho autônomo. As frondes foram envolvidas em sacos de tecido com malha de 200 mm, mraspadas do substrato, colocadas em recipientes com uma solução de formaldeído 10% e levadas ao laboratório para remoção e identificação da fauna. Quarenta e um táxons foram identificados, havendo dominância de crustáceos peracáridos. Em relação aos Mollusca, a composição específica foi diferente em relação... |

| Cerambycidae is one of the largest families of beetles and it is estimated that there are about 25,000 species of longhorned beetles in the world. However, little is known about the distribution of many species in some regions, including the Amazon. The longhorned beetles are indispensable in the ecological chain, contributing mostly to the recycling of dead wood in forest. The present study is an inventory of the Cerambycidae of the Parque Natural Municipal de Porto Velho, Rondônia, Brazil. Insects were sampled from June 2008 to May 2009 using Malaise and light traps. A total of 61 species were identified, of which 33 are new records for Rondônia and one for Amazon region, i.e., Anisopodus melzeri Gilmour, 1965. |

| Ten species of Testudines, from four different families: Chelidae, Kinosternidae, Podocnemididae, and Testudinidae, are reported from the Tiputini Biodiversity Station (Universidad San Francisco de Quito), northeastern Amazonian Ecuador; including the second report from Ecuador of Batrachemys heliostemma. These ten species are sympatric but not completely syntopic, thus I comment on their diversity and habitat preferences patterns. The general distribution of some turtles from Amazonian Ecuador is discussed, providing additional records and distribution maps for Chelus fimbriatus, Platemys platycephala, Batrachemys heliostemma, Batrachemys raniceps, Mesoclemmys gibba, Phrynops geoffroanus, Kinosternon scorpioides, and Geochelone denticulata. The presence... |

| Abstract A floristic survey of climbing plants was carried out in an ecotone area of seasonal semideciduous forest (SSF) and forested savanna (CER), in Porto Ferreira State Park (PFSP), Southeastern Brazil. We sampled the reproductive specimens every month during two periods, March 2010 to September 2011 and April and July 2015. The surveys were performed by the walking method, and the sampled individuals were classified by habit, climbing mechanism and dispersal mode. Overall, 109 species, belonging to 67 genera and 29 families, were recorded; 49 species occurred in both, 29 and 31 were exclusive to SSF and CER, respectively. Bignoniaceae and Malpighiaceae were the richest families, with 17 species, followed by... |

| Para este trabalho, foram considerados os resultados de quatro estudos que amostraram abelhas nas flores nos dois principais biomas do Estado de São Paulo: Mata Atlântica (3 localidades) e cerrado (4 localidades). Foram coletadas 276 espécies de abelhas, pertencentes a 88 gêneros: 207 espécies e 78 gêneros na Mata Atlântica e 105 espécies e 40 gêneros no cerrado. Apidae foi a família mais representada nos dois biomas. Nas áreas amostradas, as abelhas visitaram 433 espécies de plantas: 361 na Mata Atlântica e 75 no cerrado. |

| A tesourinha Tyrannus savana é um Passeriforme (Tyrannidae) migratório que ocorre no Planalto central entre os meses de agosto e fevereiro. Sua biologia reprodutiva é ainda pouco conhecida e foi abordada pelo presente estudo quanto aos seguintes aspectos: período reprodutivo, tamanho da ninhada, tempo de incubação e de permanência dos ninhegos no ninho, características dos ninhos e ovos, taxa de sucesso dos ninhos e taxa de predação. O estudo foi realizado na Estação Ecológica Águas Emendadas e em fragmentos do entorno, DF, nas estações reprodutivas de 2002 a 2007. Os ninhos (n = 78) foram monitorados em intervalos de 2-4 dias. O período reprodutivo estendeu-se de setembro a dezembro. O período médio de incubação foi de 13,6 ± 0,4 dias (n = 21) (média ±... |

| Abstract: Specimens of phanerogamic plants from the Catimbau National Park, located in northeastern Brazil, were collected during extensive fieldwork and analyzed together with information gathered from the specialized literature. A total of 613 species was recorded, belonging to 366 genera and 85 families. The largest families were Fabaceae, Poaceae, Euphorbiaceae, Asteraceae, Convolvulaceae, Malvaceae, Myrtaceae, Apocynaceae, Malpighiaceae, and Cyperaceae, comprising almost 60% of the species. The level of endemism found was below that projected in the literature, as only four known species are unique to the study area. The area is, however, home to a varied flora with high richness and numerous rare or threatened species, demonstrating the importance of... |
