1. Trophic relationships between macroinvertebrates and fish in a pampean lowland stream (Argentina)
The diet and trophic relationships between the macroinvertebrates Phyllogomphoides joaquini Rodrigues Capítulo, 1992 and Coenagrionidae (Odonata), Chironomidae (Diptera), Diplodon delodontus (Lamarck, 1919) (Bivalvia: Hyriidae), and Pomacea canaliculata (Lamarck, 1822) (Gastropoda: Ampulariidae) and the fishes Pimelodella laticeps Eigenmann, 1917 (Heptapter

2. Assessment of chromium contamination in the Monte Alegre stream: a case study
The aim of this work was to study the contamination by chromium in the sediments of the Monte Alegre stream and in the larvae of Odonata and the possible impact caused by them on the stream macroinvertebrates community. It was found that chromium contaminated the sediments and the aquatic biota. Although, the stream macroinvertebrates community structure did

3. Diet of invertebrates sampled in leaf-bags incubated in a tropical headwater stream
The diet of macroinvertebrates sampled in leaf-bags incubated in a tropical stream was analyzed on a spatial scale (one forested and one deforested area) and on a temporal scale (dry and rainy seasons). The macroinvertebrates were mostly represented by detritivores specialized in fine detritus (69%), followed by generalist detritivores (10% with a diet based

4. DIVERSIDADE DE ODONATA (INSECTA)EM SISTEMAS LÓTICOS DA SERRA DA BODOQUENA,MATO GROSSO DO SUL, BRASIL / Odonata (Insecta) from Serra da Bodoquena, Mato Grosso do Sul State, Brazil
The biggest obstacles for the conservation of tropical biodiversity are the lack of information, arising mainly from the lack of inventories of fauna in many areas. Data on distribution and species richness generated in these inventories, can subsidize these conservation plans and management of ecosystem with environmental protection, allowing the establishm

5. Neutral Theory could explain diversity of aquatic insects in streams? / A Teoria Neutra pode explicar a diversidade de insetos aquáticos em riachos?
The generality of Unified Neutral Theory of Biodiversity and Biogeography was evaluated across its support for diversity structure of Odonata adults and predators, shredders and collectors insect guilds in streams. The evaluation of Neutral Theory was done in two levels of theorys hierarchical structure. One evaluation in the level of yours assumptions, the

6. EFEITOS DA IMPLANTAÇÃO DA USINA HIDRELÉTRICA DONA FRANCISCA (RS, BRASIL) SOBRE ESTÁGIOS IMATUROS DE ODONATA (INSECTA) / EFFECTS OF DEPLOYMENT OF USINA HIDRELÉTRICA DONA FRANCISCA (RS, BRAZIL) ON IMMATURE STAGES OF ODONATA (INSECTA)
Este estudo foi realizado com o objetivo de avaliar o impacto de curto prazo da construção de uma barragem sobre a comunidade de imaturos de Odonata através da sua análise em ambientes lênticos e lóticos, antes e após o enchimento do reservatório. Na fase de pré-enchimento foram amostradas 17 estações de coleta, sendo cinco em ambientes lênticos

7. Aquatic insects as the main food resource of fish the community in a Neotropical reservoir
Neste estudo foi avaliada a dieta das espécies de peixes do reservatório de Nova Avanhandava, baixo rio Tietê, Estado de São Paulo, Brasil. Os peixes foram coletados em dois trechos do reservatório: trecho Santa Bárbara (14 coletas) e trecho Bonito (duas coletas) entre setembro de 2002 e março de 2004, utilizando-se de redes de espera e arrasto. Os re

8. Comunidade de Odonata (Insecta) em áreas naturais de Cerrado e monocultura no nordeste do Estado de São Paulo, Brasil: relação entre o uso do solo e a riqueza faunística
Stream ecosystems may be strongly influenced in different ways by land use. The effects of land-cover patterns on Odonata community were studied in eight streams and seven lakes-dams of northeastern São Paulo State. The pattern analyzed was monoculture (sugar cane) vs. nature reserve in terms of Odonata species richness and similarity. Eighty-five Odonata s

9. Efeito da alteração ambiental sobre comunidades de Odonata em riachos de Mata Atlântica de Minas Gerais, Brasil
The effect of riparian deforestation and stream impoundments on an odonate community was studied in áreas of surviving Atlantic forest in Viçosa and in Rio Doce State Park (PERD), Marliéria, Minas Gerais, Brazil. During 1997 16 species of Libellulidae, 4 Coenagrionidae, 2 Gomphidae, 2 Calopterygidae, 1 Megapodagrionidae, 1 Aeshnidae and 3 Protoneuridae we
