1. Use of hydrogeophysical data to determine the role of faults in the geometry of the Barreiras Aquifer, Brazil
Abstract Characterizing the geometry of an aquifer is fundamental for determining the locations of more productive wells. Commonly, flow and hydraulic parameters, such as transmissivity, are related to the thickness of the aquifer, which emphasizes the importance of regional hydrogeophysical characterization. Shuttle radar imagery, well profiles and geoelect

2. Mineralogy, Micromorphology, and Genesis of Soils with Varying Drainage Along a Hillslope on Granitic Rocks of the Atlantic Forest Biome, Brazil
ABSTRACT Although the physical environment of the Atlantic Forest realm is well known, studies on the soil-landform relationships are fundamental to improve the management of soil resources to facilitate sustainable development. The purpose of this study was to evaluate a representative topossequence on the “Mares de Morros” landscape of deeply weathered

3. Mineralogy of the Clay Fraction and Chemical Properties of Soils Developed from Sedimentary Lithologies of Pirambóia, Sanga-the-Cabral and Guará Geological Formations in Southern Brazil
ABSTRACT Quali-quantitative and crystallographic characterizations of the different minerals of a soil are essential for the best evaluation of its genesis, degree of weathering, active pedogenetic processes, physical and chemical properties, and its potential reserve of mineral nutrients. This study presents the results of mineralogical investigations carri

4. Cytogenetic variation of repetitive DNA elements in Hoplias malabaricus (Characiformes - Erythrinidae) from white, black and clear water rivers of the Amazon basin
Abstract Hoplias malabaricus is a common fish species occurring in white, black and clear water rivers of the Amazon basin. Its large distribution across distinct aquatic environments can pose stressful conditions for dispersal and creates possibilities for the emergence of local adaptive profiles. We investigated the chromosomal localization of repetitive D

5. Epidemiological aspects of Toxoplasma gondii infection in riverside communities in the Southern Brazilian Amazon
INTRODUCTION: Toxoplasma gondii infection is widely prevalent in humans and other animals worldwide. Information on the prevalence of T. gondii infection is scarce in some regions of Brazil, including riverside communities along the Amazon River basin. M METHODS: The prevalence of T. gondii in 231 people, aged 1-85 years, who were living in four riverside c

6. Presencia de Hydrochoerus hydrochaeris (Hydrochoeridae, Rodentia, Mammalia) en la cuenca del río Carcarañá, Santa Fe, Argentina: Comentarios acerca de su conservación y biogeografía en Argentina
Capybara (Hydrochoerus hydrochaeris) is the world largest rodent and a typical mammal of the phytogeographical provinces of Pampa and Espinal, inhabiting the eastern sector of the same. These regions have been categorized by the World Wildlife Foundation (WWF) as "critical/ endangered threatened" and are assigned the highest priority level of conservation as

7. CitogenÃtica em peixes de cabeceiras de dois riachos pertencentes à bacia do Alto rio ParanÃ, regiÃo de Toledo (PR) / Cytogenetic in fishes from two headwaters streams belonging to the Upper Paranà river basin, Toledo (PR)
Cytogenetics studies were carried out in two genera of fishes from Pindorama and Lopei streams, Upper Paranà River basin, with cytossistematic and ecologic-evolutionary approaches. In Heptapterus mustelinus, the first cytogenetics characterization in the genus was carried out, verifying 54 chromosomes (26m+18sm+4st+6a), which is a diploid number not observe

8. Observations on Haemagogus janthinomys Dyar (Diptera: Culicidae) and other mosquito populations within tree holes in a gallery forest in the northwestern region of Sao Paulo state, Brazil
In 2000, an outbreak of sylvatic yellow fever possibly occurred in gallery forests of the Grande river in the Paraná basin in the northwestern region of São Paulo state. The aim of this study was to obtain information on the bionomics of Haemagogus and other mosquitoes inside tree holes in that area. Eighteen open tree holes were sampled for immature speci

9. Morphological and structural constraints on the dynamics of the river basin of the River Benevente - Espírito Santo / Condicionantes morfológicos e estruturais na dinâmica fluvial da bacia hidrográfica do Rio Benevente - Espírito Santo
The study of watersheds in the humid tropical environment, has acquired great importance in recent decades due to growing demand for water resources planning. However, many studies have confused the concept of watersheds, believing that this was simply a network of interconnected channels that form the hydrography of the land, thus making it as simple cartog

10. Analise morfodinamica do Rio Mogi Guaçu / Morphodynamics analysis of the Mogi Guaçu River
This study shows that fluvial dynamics of the Mogi Guaçu River (NE State of São Paulo, SE Brazilian) is influenced by hydrographic basin geological structures and lithologies that sustain the river bed. These structures and lithologies affect the shape of the longitudinal profile, changing the relationships between the stream flow dynamics and sedimentary

11. ESTRUTURA GENÉTICA DAS POPULAÇÕES DE IRAPUCA (Podocnemis erythrocephala, PODOCNEMIDIDAE) DA AMAZÔNIA BRASILEIRA: IMPLICAÇÕES PARA A CONSERVAÇÃO
The chelonians of the genus Podocnemis are endemics of the Orinoco, Amazon and Araguaia basins, and historically form an important part of the cultural habitats of the local human populations who utilize meat, fat and eggs as sources of food. Podocnemis erythrocephala, also known as irapuca, has a restricted distribution, and occupies only black and clear wa

12. Hidrossolidariedade como princípio de gestão participativa de risco de inundações por associação de bacia / Hydrosolidarity as a principle of participative management of flood risk for basin association
Throughout the XXI century, a culture of solidarity within a river basin is based on legal aspects. In Brazil, it is legitimated by the Federal Constitution of 1988, article 225, caput, "Everybody is entitled to a ecologically-balanced environment, as well of common using by the people and essential to a healthy life quality, being imposed to the Public Powe
