| The benthic macroinvertebrate community structure is directly related to environmental factors such as water characteristics, habitat availability and substrate heterogeneity. This study had the purpose of characterizing the benthic macroinvertebrate community and compare its attributes in streams located inside (preserved area) and outside (altered area) the Iguaçu National Park, in the west of Parana, Brazil, in two season (dry and rainy). Three replicates per site were obtained through the Surber collector in four microhabitats (litter pool, litter riffle, substrate pool and substrate riffle). There was significant discrimination in the benthic fauna composition among the study areas (Wilks=0.091; F272,746= 2.249; P<0.0001). The taxa Corbiculidae,... |

| A vegetação é parte importante no equilíbrio da Terra, pois permite manter a vida dos animais, a qualidade do solo e da água. Devido a sua importância, esta cartilha apresenta conceitos e técnicas para conservar e recuperar um tipo particular de vegetação, as matas de galeria, importantes para a preservação de rios que fazem parte das bacias hidrográficas no Cerrado. |

| Esse manual para recuperacao de Matas de Galeria da regiao do Brasil Central enfatiza que os plantios devem utilizar especies nativas do local a ser reabilitado, respeitando as condicoes encontradas na microbacia, tais como umidade, fertilidade do solo e luminosidade. As sugestoes propostas procuram reestruturar o ambiente de forma que este retorne o mais rapido e semelhante possivel as condicoes originais, buscando atender a crescente demanda da sociedade e do governo que solicitam subsidios para recuperar matas que foram degradadas por causa das pressoes do desenvolvimento economico. O manual foi elaborado com base na experiencia dos autores, em pesquisas de campo e de laboratorio, alem de sintetizar informacoes disponiveis na literatura. O texto busca... |

| ABSTRACT Diversity patterns and their causes remain important questions, especially for ecosystems that preserve natural conditions. This is the case of fish diversity in large Neotropical rivers. In this context, we investigated fish diversity patterns along an extensive unregulated river section (ca. 450 km) in the Middle Uruguay River Basin. Sampling was conducted seasonally between May 2017 and March 2018, at six sites (patches) with contrasting environmental conditions. We collected 3,008 individuals belonging to 90 species. Nine were migratory, which summed relevant biomass in local assemblages (20 to 60%). We observed spatial variation in assemblage structure, but weak seasonal effects. Overall, biomass was similar among sites, but richness tended... |

| This study addressed the feeding ecology of fish fauna from a first-order stream located in a rural area. The purposes were to evaluate the influence of interspecific, seasonal and spatial factors on the diet, examine the dietary overlap, and determine the predominant food sources. Sampling was conducted in December 2007, September 2008, and March 2009, in three 50-m stretches of Itiz stream (upstream, intermediate, and downstream), through electrofishing. A total of 1,102 stomach contents were analyzed from 14 species, by the volumetric method. In general, allochthonous resources were predominant in the diets. Astyanax aff. fasciatus, Astyanax aff. paranae, Astyanax bockmanni, and Bryconamericus aff. iheringi consumed a higher proportion of plant remains,... |

| Comparative abundance and diversity of Dryininae (Hymenoptera, Dryinidae) in three savannah phytophysiognomies in southeastern Brazil, under three sampling methods. This study aimed to assess the abundance and diversity of Dryininae in riparian vegetation, Brazilian savannah, and savannah woodland vegetation at the Estação Ecológica de Jataí, in Luiz Antônio, State of São Paulo, Brazil, by using Moericke, Malaise, and light traps. The sampling was carried out from December 2006 to November 2009, and 371 specimens of Dryininae were caught, with the highest frequencies in spring and summer. Fourteen species of Dryinus Latreille, 1804 and one of Thaumatodryinus Perkins, 1905 were identified. The highest frequencies of Dryinus in the riparian vegetation... |
