| O presente trabalho objetivou investigar a relação entre a velocidade da água e a distribuição dos estágios imaturos de Chirostilbia pertinax (Kollar, 1832) e os macroinvertebrados bentônicos associados. As coletas foram realizadas em cinco pontos, no trecho superior do Rio dos Sinos, no Estado do Rio Grande do Sul. A fauna bentônica foi amostrada com substratos artificiais, que permaneceram instalados nos locais de maior corenteza d'água por períodos de 14 dias. Antes do recolhimento dos substratos foram realizadas medidas de velocidade d'água no local da sua instalação. Essas medidas foram agrupadas em três classes: baixa (0,20 a 0,63 m/s), média (0,64 a 1,07 m/s) e alta (1,08 a 1,50 m/s) para posterior relação com a distribuição da fauna coletada. Para... |

| What is the importance of open habitat in a predominantly closed forest to the dung beetle assemblage? The Atlantic Forest in Brazil is one of the most highly disturbed ecosystems and is mainly represented by fragmented areas. However, in places where human disturbances have ceased, certain areas are showing a natural regeneration pattern. The aim of the present study was to determine how the dung beetle assemblage responds to distinct habitat structures in a fragment of Atlantic Forest. For such, open and closed forest areas were sampled in a fragment of the Atlantic Forest in the northeastern region of Brazil. Pitfall traps baited with excrement and carrion were used to collect the beetles. A total of 7,267 individuals belonging to 35 species were... |

| When rare is just a matter of sampling: Unexpected dominance of clubtail dragonflies (Odonata, Gomphidae) through different collecting methods at Parque Nacional da Serra do Cipó, Minas Gerais State, Brazil. Capture of dragonfly adults during two short expeditions to Parque Nacional da Serra do Cipó, Minas Gerais State, using three distinct collecting methodsaerial nets, Malaise and light sheet trapsis reported. The results are outstanding due the high number of species of Gomphidae (7 out of 26 Odonata species), including a new species of Cyanogomphus Selys, 1873, obtained by two non-traditional collecting methods. Because active collecting with aerial nets is the standard approach for dragonfly inventories, we discuss some aspects of the use of traps,... |

| White grubs (Coleoptera, Melolonthidae) in the "Planalto Region", Rio Grande do Sul state, Brazil: Key for identification, species richness and distribution. The objective of this study was to survey the occurrence and geographic distribution of white grub species (Coleoptera, Melolonthidae) in cultivated and non-cultivated fields of the "Planalto Region", Rio Grande do Sul state, Brazil and develop a key at genus-level. Twenty-eight species from 15 genera and three subfamilies were recorded: Dynastinae, Melolonthinae and Rutelinae. The species or genera recorded for the first time in the state are: Cyclocephala metrica, C. tucumana, Isonychus albicinctus, Liogenys bidenticeps, L. fusca, L. obesa and L. sinuaticeps, Paranomala violacea, as well as... |

| ABSTRACT We measured variation and covariation in wing morphology in six populations of the fly Polietina orbitalis (Stein) (Diptera: Muscidae) to test for geographic morphological structure. Additionally, we examined the role of environmental variables in determining geographic variation in wing shape. We sampled five populations in the state of Paraná, southern Brazil (Colombo, Fênix, Guarapuava, Jundiaí do Sul and Ponta Grossa), and one in Paraguay (Mbaracayú). We choose 15 landmarks to describe the wing shape and size and 19 environmental variables to describe the local environmental conditions. Our results showed that P. orbitalis wing shape, but not size, varies geographically. A canonical variate analysis showed the existence of two clusters of... |

| For the first time, we identified the insect herbivore that induces one of the most conspicuous galls on the leaves of Caryocar brasiliense Camb. (Caryocaraceae), a widespread, typical cerrado woody plant of large economic importance. The gall inducing organism is a new and undescribed species of Eurytoma sp. (Hymenoptera, Eurytomidae). Furthermore, we recorded its spatial distribution within C. brasiliense trees. More Eurytoma galls were found on the eastern tree slope, followed the southern and northern slopes. More galls were found in the interior of the tree crown, i.e., on the proximal portion of the stems compared to the terminal portion. At the leaf level, more galls were found on the median region compared to the distal or proximal, perhaps due to... |

| Morphological traits, such as size and shape, may reflect a combination of ecological and evolutionary responses by organisms. Ants have been used to evaluate the relationship between the environment and species coexistence and morphology. In the present study, we analyzed the morphology of workers of Gnamptogenys striatula Mayr in different landscapes from the Atlantic Domain in southeastern Brazil, focusing on the variation in the morphological attributes of these populations compared to those from a dense ombrophilous forest. Eighteen morphological traits of functional importance for interactions between workers and the environment were measured to characterize the size and shape of the workers. In general, the results show that ants of urban areas... |
