1. How much do we know about the groundwater quality and its impact on Brazilian society today?
Resumo As águas subterrâneas são um recurso imprescindível para a sociedade e o meio ambiente no Brasil. Mais de 557 m3/s (17.5 km3/a) são extraídos através de 2.5 milhões de poços para atender a demanda nas cidades e no campo, gerando uma economia de R$ 56 bilhões ao ano (US$ 14 bilhões/ano). O aquífero tem função impar no ciclo hidrológico,

2. Restoring Ecological Functions Using Agroforestry Systems in Riparian Forests
ABSTRACT Agroforestry systems and restoration models were compared with native forests by examining the restoration of ecological processes that generate stability, resilience and reliability. The stability assessment was obtained using indicators of diversity, structure and functionality. Indicators of soil protection and nutrient cycling were also used to

3. Limnology of shallow lakes of the semi-arid Central Pampa of Argentina
Resumo Objetivo No Pampa Central da Argentina, há três regiões fitogeográficas criadas pela diminuição da precipitação vinda do oeste. Essa região possui um grande número de lagos sendo a maioria desses temporários com hidroperíodos definidos por ciclos climáticos, embora alterados pela ação antrópica. Alguns desses lagos foram estudados co

4. IMPACT OF LAND USE CHANGE ON THE WATER BALANCE IN A REPRESENTATIVE WATERSHED IN THE SEMIARID OF THE STATE OF PERNAMBUCO USING THE SWAT MODEL
ABSTRACT The Brazilian semiarid region present high rainfall variability and long dry periods. Thus, the main springs and streams are generally intermittent, and both native vegetation and human activities have a strong influence on hydrological processes and the water yield in the watershed. The aim of this study was to investigate the impacts of reforestat

5. Seasonal Variability of Trace Elements by Soil Depth in a Protected Area
ABSTRACT Conservation units are legally protected areas containing natural fragments of Brazilian biomes. They may contain forest areas and can be found near to urban areas, which exposes them to pollutants. The Cicuta Forest Area of Relevant Ecological Interest (ARIE) is located in Volta Redonda and Barra Mansa-RJ, cities with industrial activity and near

6. Occurrence of Yeast Species in Soils under Native and Modified Vegetation in an Iron Mining Area
ABSTRACT Soils of the Quadrilátero Ferrífero are rich in mineral resources, especially gold and iron. Soil management and mining activities greatly impact soil biology. However, studies addressed to the diversity of microorganisms and their ecological role in the recovery of these areas are scarce. This study aimed to assess the yeast occurrence in soils w

7. Responses of water mite assemblages (Acari) to environmental parameters at irrigated rice cultivation fields and native lakes
ABSTRACT Many studies have revealed that water mite communities can be affected by the physical and chemical parameters of the water. The similarity between the water ‘mite assemblages in local water bodies and in irrigated rice areas can be a way to measure the water conditions, enabling an assessment of the anthropic impact in the environment. The aim of

8. Terrestrial impact structures as geoheritage: an assessment method of their scientific value and its application to Brazil
ABSTRACT Terrestrial impact structures are geological and geomorphological features with particular importance to understand the history and evolution of the planet. Impact structures are scattered around the world but in many countries these features are under threat, essentially due to anthropic factors. Impact structures with higher scientific value shoul

9. Genética aplicada à ecologia de estradas: um estudo na estrada municipal Guilherme Scatena (São Carlos, SP) e potencial impacto na biodiversidade local.
Roads generate a large ecological impact to wildlife by raising barriers among ranges of species originally continuous and for causing road-kills. After road-killing, a morphological identification becomes impossible for the loss of diagnostic features, especially in the case of small vertebrates. Use of molecular tools for identification is an alternative t

10. Macrolgae as an indicator of the environmental health of the Pirangi reefs, Rio Grande do Norte, Brazil
The coral reefs of Pirangi beach have suffered the impact of anthropic actions, mainly those related to tourism. To evaluate these effects, algal samples were collected at nine stations, distributed along the reef fringe. The macrobenthic community (algae/coral) was identified through photographic methods. A total of thirty species of algae, five species of

11. Estoque de carbono nos solos da bacia do Rio Araguari-MG: estimativas, modelagem e cenários
The soils can act as a source or carbon sink to the atmosphere, depending on the climate conditions and, especially, the type of use and management adopted. Taking into consideration the stock/sequestration carbon potential, admittedly, attributed to several land uses, as in planted forests (Pinus and Eucaliptus), and no-till areas, as well as the efficiency

12. Diversidade da fauna de Squamata em fragmentos florestais urbanos de Juiz de Fora, Minas Gerais, Brasil
A maior parte dos remanescentes florestais, na região sudeste do Brasil, se encontra em forma de fragmentos florestais, e por isso o interesse da comunidade científica em estudá-los e analisar as conseqüências sobre a biodiversidade. Pretendeu-se, portanto, avaliar a diversidade da herpetofauna em fragmentos urbanos de Mata Atlântica em Juiz de Fora, n
