1. Reproductive phenology of aquatic macrophytes in the Cerrado-Pantanal ecotone
ABSTRACT Studies of plant phenology have been performed predominantly with terrestrial species and rarely so with aquatic communities. Such plants are fundamental for the aquatic ecosystems, representing a valuable source of resources when they are scarce in terrestrial environments for the fauna. Studies of phenology help to understand the reproduction rhyt

2. O valor do serviço de proteção de mananciais
RESUMO Unidades de conservação são espaços protegidos que prestam serviços ambientais continuamente para toda a sociedade. O Serviço de Proteção aos Mananciais de abastecimento público (SPM) é um desses serviços. Como previsto no art. 47 do Sistema Nacional de Unidades de Conservação (SNUC), Lei nº 9.985, de 2000 (BRASIL, 2004b), deve contribui

3. Actual status of fishing reserves of the Yesil River
ABSTRACT In this article, the study and prediction of the state of fish resources in the Yesil River was carried out to determine the boundary reference points of the reserve and management decisions in case they are exceeded, to ensure sustainable fisheries and preserve biological diversity. Ichthyological studies, retrospective analyses and rankings of the

4. Análise crítica por comparação entre modelos de qualidade de água aplicados em rios poluídos: contribuições à saúde, água e saneamento
RESUMO Este artigo discute a dispersão no ambiente da matéria orgânica presente no esgoto doméstico a partir de modelos oxigênio dissolvido-demanda bioquímica de oxigênio (OD-DBO). O modelo relaciona a poluição de corpos d'água por matéria orgânica e a queda dos níveis de OD. Dá-se destaque à modelagem de diferentes tipos de lançamentos da ca

5. Eco-hidrologia integrada ao manejo dos recursos hídricos em áreas úmidas: caso do Banhado do Taim, RS
RESUMO A eco-hidrologia busca integrar os conhecimentos da hidrologia aos da ecologia, criando uma abordagem mais ampla para a compreensão da dinâmica dos recursos hídricos, facilitando o planejamento e as ações de programas de gestão. Uma das formas de integrar hidrologia à ecologia é por meio da elaboração de índices de adequabilidade de hábita

6. Hydropedology of a High Tableland with Cerrado, Brazilian Central Plateau: the Frutal Catchment Case Study
ABSTRACT: Currently, the Brazilian savanna (Cerrado) represents the main agricultural area of the country, comprising a great variety of landscapes and soils, geological formations and vegetation patterns, as well as the major watershed. We studied the hydropedology and morphometry of a representative catchment (Frutal river), on a high tableland (Chapada) i

7. Antiherbivory defense mechanisms along an environmental gradient in restinga
ABSTRACT Plant-herbivore interactions have directed the evolution of defense mechanisms in plants, which can vary intraspecifically according to environmental quality. This study evaluated variation in the production of antiherbivory defenses in plant species distributed along an environmental gradient of restinga. The study was performed in Parque Estadual

8. Estimates of Annual Soil Loss Rates in the State of São Paulo, Brazil
ABSTRACT: Soil is a natural resource that has been affected by human pressures beyond its renewal capacity. For this reason, large agricultural areas that were productive have been abandoned due to soil degradation, mainly caused by the erosion process. The objective of this study was to apply the Universal Soil Loss Equation to generate more recent estimate

9. Water Erosion on an Oxisol under Integrated Crop-Forest Systems in a Transitional Area between the Amazon and Cerrado Biomes
ABSTRACT Water erosion is one of the main factors driving soil degradation, which has large economic and environmental impacts. Agricultural production systems that are able to provide soil and water conservation are of crucial importance in achieving more sustainable use of natural resources, such as soil and water. The aim of this study was to evaluate soi

10. Tissue culture of ornamental cacti
Cacti species are plants that are well adapted to growing in arid and semiarid regions where the main problem is water availability. Cacti have developed a series of adaptations to cope with water scarcity, such as reduced leaf surface via morphological modifications including spines, cereous cuticles, extended root systems and stem tissue modifications to i

12. Aperfeiçoamento do emprego da equação universal de perda de solo na aplicação do pagamento por serviços ambientais da política espírito-santense de recursos hídricos
The mechanism of Payment for Environmental Services is a management tool in water resources policy of the state of Espírito Santo, which has the project Produtores de Água as part of this. This project is based on soil conservation for improvement/maintenance of water quality of streams and, therefore, offers financial compensation to those that preserve o
