1. Oportunidades e desafios para a aquicultura em reservatórios brasileiros: uma revisão
Resumo Objetivo A aquicultura apresenta grande importância no cenário mundial e brasileiro. A construção artificial de grandes corpos de água, como açudes e reservatórios, aumenta o potencial de cultivo de peixes em tanques-redes nesses ambientes, gerando conflitos sobre o uso dessas águas públicas, onde de um lado está a cadeia produtiva buscand

2. Taxonomy, distribution and population structure of invasive Corbiculidae (Mollusca, Bivalvia) in the Suquía River basin, Córdoba, Argentina
Invasive species are one of the most significant causes of biodiversity loss and changes in ecosystem services, which underlines the importance of their detection and their study. The Asian clams (Corbiculidae) are invasive organisms that accidentally entered the La Plata River, Argentina, presumably in the 1960s. The objectives of the present study were to

3. Bioacumulação de metais pesados e nutrientes no mexilhão dourado do reservatório da Usina Hidrelétrica de Itaipu Binacional
This study aims to evaluate the bioaccumulation of macronutrients and heavy metals in the golden mussel according to its collection site and seasonality in the aquaculture area of the reservoir from April/2009 to March/2010. There is no difference (p > 0.05) in the concentration of metals with respect to the point of collection. The concentrations of Cu, Fe,

4. TRANSMISSÃO GERACIONAL E A PRESENÇA DA ESCOLA NA FORMAÇÃO DA CONSCIÊNCIA AMBIENTAL Estudo exploratório de famílias que convivem em áreas de proteção aos mananciais
This project proposes to conduct research to raise the influence of educational processes and awareness processes with two groups of families in three generations, which live in areas of protection of the sources of the Billings reservoir, having held these reserves of hydro high strategic importance and, secondly, shows the fragility of their ecosystems and

5. Contribuição metodológica para a pré-identificação de áreas adequadas à implantação de parques aquícolas no Reservatório de Nova Ponte - Minas Gerais / Methodological contribution for the delimitation of fish farms in tanks in the Reservoir of Nova Ponte - Minas Gerais
The purpose of this thesis is to propose a methodology for the delimitation of fish farms in tanks. The proposed methodology was applied in the reservoir of Nova Ponte - MG, with the cultivation in net cages of the Red-tailed Lambari (Astyanax fasciatus), Piracanjuba (Brycon orbygnianus) and Tilapia (Tilapia sp.) species, using GIS. It was surveyed the facto

6. TEMPORAL EVALUATION OF LIMNOLOGIC VARIABLES AT RODOLFO COSTA E SILVA RESERVOIR - RS, AND THE LAND USE IN THE DAM UP AREA / AVALIAÇÃO TEMPORAL DE VARIÁVEIS LIMNOLÓGICAS DO RESERVATÓRIO RODOLFO COSTA E SILVA - RS, E O USO DA TERRA NA ÁREA DE CAPTAÇÃO
The relationship between man and environment initially happens in a natural way. After a while, there is an accelerated populational growth, and new technology comes, which intensifies the human actions both in the terrestrial environment and in the aquatic one, imposing, therefore, unbalance in the relation man-nature. Thus, quantitative and qualitatively,

7. Medidas não convencionais de reservação dágua e controle da poluição hídrica em lotes domiciliares / Unconventional measures of reservoir water and control water pollution in urban lots
This paper aims to analyze the reduction of hydropollution through monitoring non conventional reservation of water applied in urban lots starting from individual and global efficiency integrated to the lot. It also prioritizes the monitoring of both quality and quantity of pollution and the rain flow from its draining. The inclusion of these measurements on

8. Eutrophication of Cruzeta reservoir in the representative basin of the Seridó river - RN. Natal / Eutrofização do Reservatório Cruzeta na bacia representativa do rio Seridó RN
Eutrophication has been listed as one of the main problems of water pollution on a global level. In the Brazilian semi-arid areas this problem takes even greater proportions due to characteristical water scarcity of the region. It is extremely important to the predictive eutrophication models development and to the reservoirs management in the semi-arid regi

9. Pré-cloração associada à adsorção em carvão ativado em pó e flotação por ar dissolvido na remoção de microcistina presente em três diferentes concentrações em águas provenientes de reservatório eutrofizado / Prechlorination associated to adsorption with powdered activated carbon and dissolved air flotation in the removal of three concentrations of microcystin present in eutroficated reservoir water
The disordered growth of cities, the use of planting areas near the water sources and the launch of domestic and industrial wastewater without treatment are the main sources of water bodiespollution. Such pollution contributes to increase the nutrient loading in the water bodies. In association with climatic factors, this enrichment of nutrient provides suit

10. Estudo da comunidade fitoplanctônica como bioindicador de poluição em três reservatórios em série do Parque Estadual das Fontes do Ipiranga (PEFI), São Paulo, SP / Phytoplankton communitys study as bioindicator of pollution in three cascading reservoir system in Parque Estadual das Fontes do Ipiranga (PEFI), São Paulo, SP
The three shallow cascading reservoir system are located in Parque Estadual das Fontes do Ipiranga (PEFI) Biological Reserve in the southern of São Paulo city where located headwater Ipiranga Stream. The first reservoir is linked to Lago das Garças, a shallow and eutrophic environment, where have become frequent blooms of Cyanobacteria that produce aggress

11. Avaliação do risco de contaminação de mananciais hídricos para o abastecimento: o caso da bacia da barragem do descoberto
In catchments where the threat of impairment is due to non-point pollution, identifying the critical areas that contribute a large amount of pollutants is of paramount importance for the sustainable development of the watershed. Often resources for catchments management are poor and there is no way to establish a comprehensive monitoring system or to calibra

Aiming to identify the apportionment of pollution sources/factors with a view to get better information about the water quality at Jaibaras watershed, a research composed of three steps was developed. In the first step (Step I), it was identified the water pollution sources at the upland of Jaibaras watershed until Ayres de Souza dam. The survey occurred fro
