37. ComposiÃÃo, abundÃncia e dinÃmica reprodutiva e alimentar de populaÃÃes de peixes de um reservatÃrio recÃm-formado (UHE - Capim Branco I / MG)
The loss of diversity is one of the main damage to the environment caused by the construction of reservoirs and it is related to the disappearance of terrestrial habitats by flooding, and the changes produced in the aquatic habitat. These changes reflect, above all, in the availability of food and in the reproduction of the fish species, leading to a remarka

38. Distribuição de Trichoptera Kirby, 1813 (Insecta) em riachos de Mata Atlântica da Serra de Paranapiacaba, Estado de São Paulo, Brasil. / Distribution of Trichoptera Kirby, 1813 (Insecta) in Atlantic Rainforest streams of Serra de Paranapiacaba, São Paulo State, Brazil.
Data on the fauna of immature stages of Trichoptera were gathered for sites within and outside the range of conservation units in Serra de Paranapiacaba, State of São Paulo, aiming to test the effects of environmental variables and degree of environmental integrity on faunistic composition, abundance and richness of larvae. The relationship between abundanc

39. Ciclo de vida, produtividade secundária, distribuição, alimentação e crescimento de Massartella brieni (Lestage) (Ephemeroptera: Leptophlebiidae) em riachos do Parque Estadual Intervales, Estado de São Paulo / Life cycle, secondary production, distribution, feeding habits and growth of Massartela brieni from streams of the Parque Estadual Intervales, State of São Paulo
The present work had as general aim to study the life cycle, secondary production, distribution, feeding habits and growth of Massartela brieni from streams of the Parque Estadual Intervales, State of São Paulo. The analyzed material was collected in six collection stations, one in Roda d´Água stream, one in Mirante stream, one in Bocaina stream, two in �

40. Insectos acuáticos asociados a los lagos interdunarios de la región central del Estado de Veracruz, México
The aim of this study is to register the presence of aquatic insects during the rainy and dry seasons, in 15 dune lakes of the Gulf of Mexico's coastal zone. These ecosystems lodge a wealth of 62 families, 60 of them present during the rainy season and 46 during the dry period. At both times Coleoptera is the order with a greater number of families, followed

41. DISTRIBUIÇÃO ESPACIAL E TEMPORAL DOS INSETOS E OLIGOCHAETA AQUÁTICOS DA SUB-BACIA DO CÓRREGO SÃO PEDRO, JUIZ DE FORA, MINAS GERAIS
In order to obtain information about the spatial and temporal variation of Oligochaeta fauna and aquatic insects and to use this information to characterize the environmental quality of Córrego São Pedro Subbasin (which is part of the drainage basin of Paraibuna River, Juiz de Fora city, Minas Gerais state, Brazil) we collected sediment samples at 5 spots

42. Ecologia trófica da comunidade de peixes do reservatório do Lobo (Broa), Brotas-Itirapina/SP, com ênfase à introdução recente da espécie alóctone Cichla kelberi (Perciformes, Cichlidae).
The introduction of predatory species has carrying deep modifications on the original fish wildlife structure at aquatic environments. The feeding spectrum characterization of fish community from Lobo Reservoir (Broa), beside providing information about the species biology and establishing trophic guilds, made possible the follow-up of trophic alterations du

43. Macroinvertebrados em córregos da região da Mata Atlântica (Sudeste do Brasil) : influência da cultivo de banana
A integridade dos ecossistemas aquáticos tem sido comprometida por inúmeras ações antrópicas, como por exemplo, pela agricultura extensiva que tem mostrado alterações na qualidade de água e nas características da comunidade aquática. Muito se conhece a respeito de plantações anuais, como da cana-de-açúcar, sojas, milho, etc., mas pouca informa�

44. Padrões de diversidade e organização temporal de Chironomidae (Diptera) em um córego tropical
In this study we investigated the temporal dynamics of a chironomid assemblage in a forested stream located in southeastern Brazil. First, we analyzed some diversity patterns of this assemblage by describing two macroecological relationships (body size-species richness and body size-abundance) and by testing with they vary in an intra-annual scale. Second, w

45. A ordem Ephemeroptera no Brasil (Insecta): Taxonomia e diversidade / The order Ephemeroptera (Insecta) in Brazil: Taxonomy and diversity
The main objectives of this thesis was to improve the knowledge regarding the order Ephemeroptera, or Mayflies, in Brazil, as well as provide bases for future studies by taxonomists of this group and ecologists of aquatic insects in the country. The first step was to establish, based on literature, the less documented areas of Brazil regarding mayflies. Afte

46. The ANUROFAUNA Of FORMATION CRATO, EOCRETÃCEO Of the BASIN Of the ARARIPE / A ANUROFAUNA DA FORMAÃÃO CRATO, EOCRETÃCEO DA BACIA DO ARARIPE,
The Crato Formation, Araripe Basin, has yielded one of the most important Early Cretaceous fossil assemblages world-wide, being specially famous for the abundance, taxonomic diversity, and exceptional preservation of its fossils. Its beds contain remains of a continental flora and fauna that have been interpreted to represent a lacustrine environment. The ai

47. Efeitos dos macroconsumidores (peixes e camarões) sobre a assembléia de insetos aquáticos e na taxa de degradação de folhas em riachos de floresta de terra firme, Amazônia central
Este trabalho teve como objetivo verificar os potenciais efeitos sobre a assembléia de insetos aquáticos e degradação de folhas causados pela exclusão de macroconsumidores (peixes e camarões). A diminuição na taxa de degradação e o aumento na abundância de alguns táxons eram esperadas na ausência de macroconsumidores, como observado em outros es

48. Alterações morfofuncionais e metabólicas no teleósteo de água doce matrinxã, Brycon cephalus (Günther, 1869) exposto ao organofosforado metil paration (Folisuper 600BR).
The xenobiotics influxes into the aquatic systems are continuous increasing in Brazil due to their use in the agriculture and to control insects in aquaculture. In the present study was evaluated if the exposure of the freshwater teleost fish matrinxã (Brycon cephalus) to sublethal concentration of the organophosphorus pesticides methylparathion (MP) induce
