1. Shelf-life of loricariid catfish (Pterygoplichthys disjunctivus [Weber, 1991]) roe stored in ice
Abstract Loricariid catfish (Pterygoplichthys disjunctivus [Weber, 1991]) has invaded water catchments throughout the world, due to the lack of predators and high fecundity. An approach to control its population could be using its roe as food; however, more knowledge is needed. Thus, the present study aimed to evaluate the shelf-life of fresh loricariid catf

2. Spectral analysis in determining water quality sampling intervals
RESUMO Para gerar séries históricas de qualidade da água mais representativas desenvolvem-se técnicas de monitoramento em tempo real. Contudo, estas técnicas possuem obstáculos quanto ao uso: alto custo, dificuldades de instalação, manutenção e calibração dos equipamentos. Uma alternativa seria o chamado monitoramento da qualidade da água em tem

3. Processos hidrológicos em uma sub-bacia do Parque Estadual da Serra do Mar, núcleo Santa Virgínia
Resumo O presente estudo busca caracterizar o funcionamento hidrológico de uma sub-bacia com cobertura de Mata Atlântica, localizada no Parque Estadual da Serra do Mar, núcleo Santa Virgínia. Para isso, foram monitorados entre os anos de 2008 e 2009, alguns processos hidrológicos: escoamento superficial, umidade do solo (0,15, 0,30, 0,50 e 0,90 metros d

4. Modified NRCS-CN-TUH methods for distributed rainfall-runoff modeling
RESUMO Pela facilidade de aplicação, os métodos CN e Hidrograma Unitário Triangular (HUT) são muito usados em projetos de obras hidráulicas. Este trabalho adapta tais métodos para incorporar a variabilidade espacial das características físicas da bacia hidrográfica. O tempo de viagem (tv) do escoamento é computado do MDE e os métodos CN e HUT s�

5. Spatial and Temporal Potential Groundwater Recharge: the Case of the Doce River Basin, Brazil
ABSTRACT: Little is known about the groundwater recharge potential of weathered tropical catchments, where increasing water uptake is widespread to meet various water demands. This study aimed to estimate the volume of groundwater recharge of the Doce River Basin, Minas Gerais, Brazil. The BALSEQ model was applied to calculate the water balance over a period

6. Phosphorus Forms in Sediments as Indicators of Anthropic Pressures in an Agricultural Catchment in Southern Brazil
ABSTRACT Phosphorus (P) fractionation is a suitable procedure to ascertain P lability in sediments and is able to distinguish sources of P under different soil management practices in a catchment. Brazil is the second largest producer and the largest exporter of tobacco in the world. Inadequate management of cultivated areas exposes the soil to erosion proce

7. Hydrological Modeling of Tributaries of Cantareira System, Southeast Brazil, with the Swat Model
ABSTRACT The lack of hydrological data in Brazil is the main limitation for structuring hydrological models, which are able to assist water resources management. Therefore, studies are needed to evaluate the performance of models without on-site calibration. Within this context, the aim of this study was to calibrate the SWAT hydrological model for the Caman

8. Polymerase chain reaction and nested-PCR approaches for detecting Cryptosporidium in water catchments of water treatment plants in Curitiba, State of Paraná, Brazil
Introduction Cryptosporidium is an important protozoan cause of waterborne disease worldwide of concern to public health authorities. To prevent outbreaks of cryptosporidiosis, the monitoring of this parasite in drinking water is necessary. In the present work, the polymerase chain reaction (PCR) and nested-PCR techniques were used to detect Cryptosporidium

9. Chumbo e zinco em águas e sedimentos de área de mineração e metalurgia de metais
Lead metallurgy at Adrianópolis is the largest environmental problem of Paraná, Brazil. The objective of this study was to determine Pb and Zn levels in water and sediment in two catchments by different extraction methods. The high levels of lead in water in most of samples do not allow the human use. Total Pb concentration as high as 795.3 µg L-1 was obs

10. Aproveitamento de água de chuva no meio urbano e seu efeito na drenagem pluvial
There is an increasing interest from the society in rainwater harvesting and use in urban areas, due to the benefits that this practice provides, such as: economic, environmental and urban flooding control. This interest may be perceived by the emergence of government regulations and increased availability of specific products in the domestic market for the

11. Macrobenthic community structure in a Brazilian chocked lagoon system under environmental stress
Saquarema-Jaconé lagoonal system (SJLS) comprises a sequence of five interconnected shallow brackish lagoons with access to the sea by a single permanent tidal channel. It is a eutrophic system, receiving constant input of organic load from its urbanized catchments. The relationship between several environmental variables and the spatial-temporal distributi

12. Modelagem da dinâmica do nitrogênio em uma micro-bacia com cobertura florestal no Parque Estadual da Serra do Mar, Núcleo Santa Virginia / Modeling of nitrogen dynamics in a forest coverage catchment in the Serra do Mar State Park, Santa Virginia Nucleus
A Mata Atlântica é um ecossistema reconhecidamente ameaçado, considerado um dos biomas prioritários para execução de políticas de conservação. Sua área florestal, reduzida atualmente a menos de 12% de sua cobertura original, necessita atenção especial em termos de compreensão do seu funcionamento como subsídio para sua melhor conservação. O n
