13. Susceptibility of Argentinean Biomphalaria tenagophila and Biomphalaria straminea to infection by Schistosoma mansoni and the possibility of geographic expansion of mansoni schistosomiasis
Introduction Human migration and the presence of natural vectors (mollusks) of Schistosoma mansoni are the primary causes of the expansion of mansoni schistosomiasis into southern areas of South America. Water conditions are favorable for the expansion of this disease because of the extensive hydrographic network, which includes the basins of the Paraná a

14. Phylogeographic pattern of Jenynsia multidentata(Cyprinodontiformes: Anablepidae) in the southern boundary of the Brazilian Subregion, Argentina
The Atlantic drainage basins are located in the southern Pampean area, in the southernmost part of the Brazilian subregion. Tectonic and paleoclimatic phenomena, occurring during the Quaternary, have currently isolated these basins from the present hydrographic system. Their ichthyofaunal composition is similar to that of hydric systems located further north

16. Karyotypic conservatism in five species of Prochilodus (Characiformes, Prochilodontidae) disclosed by cytogenetic markers
The family Prochilodontidae is considered a group with well conserved chromosomes characterized by their number, morphology and banding patterns. Thence, our study aimed at accomplishing a cytogenetic analysis with conventional methods (Giemsa staining, silver staining of the nucleolus organizer regions-AgNOR, and C-banding) and fluorescence in situ hybridiz

17. Análise dos critérios de priorização de projeto junto ao fundo estadual de recursos hídricos do Estado de São Paulo: estudo de caso do Comitê da Bacia Hidrográfica do Tietê-Jacaré
The State Water Resources Fund of São Paulo (FEHIDRO) was established by the 7.633 State Law, of December 30 of 1991, to give financial support to the hydrographic basins actions. The resources from this fund are distributed in the Water Basis Committees (CBH) every year, each CBH is responsible for finding the way to select the projects. This research aime

18. FLUTUAÇÃO DOS NÍVEIS DE ÁGUA SUBTERRÂNEA EM MICROBACIAS HIDROGRÁFICAS DO RIO VACACAÍ-MIRIM / GROUNDWATER LEVELS FLUCTUATION IN VACACAÍ-MIRIM RIVER SMALL WATERSHEDS
The intention in this work is to study (locally) the fluctuation system of groundwater levels in two small watersheds. We selected Rancho do Amaral and Rincão do Soturno small watersheds for being representative of the first order streams which compose the Vacacaí-Mirim river watershed headwaters. Both are located at the border of Paraná Sedimentary Basin

19. A criação dos Comitês de Bacias Hidrográficas dos rios Jucu e Santa Maria da Vitória : perspectivas e desafios da gestão hídrica capixaba
It examines the process of creating the Watershed Committees Jucu rivers and Santa Maria da Vitoria, which are located in the metropolitan area of Vitoria in Espirito Santo State, highlighting the current status of these Committees and their future prospects. This region is considered socio-economically and environmentally strategic due to the fact that the

20. Regionalização de vazões de referência Q7,10 e Q90
The main objective of the research was the study and application of different methods for estimating ten years return period minimum annual seven consecutive days low flows (Q7,10) and minimum flows associated with remaining 90% in time (Q90), for the region between Doce and Itabapoana basins, through the hydrological regionalization. The three compared meth

21. Avaliação e identificação de parâmetros importantes para a qualidade de corpos d'água no semiárido baiano. Estudo de caso: bacia hidrográfica do rio Salitre
Objective of this work was identifying superficial water quality parameters, significant to semi-arid hydrographic basins, minimizing costs of water monitoring. The Salitre river basin, an important sub-basin of the São Francisco river, was used as a case study. STD, Cl-, DO, BOD, pH, NO3-, PO4(3-), Al, Cu, Fe, Mn, Ni and Pb were considered the most signifi

22. Tipologia e fragmentação das terras úmidas do cerrado na alta bacia do Rio Araguaia, estado de Goiás / Typology and fragmentation wetland savanna int he high Araguia River basin, Goiás state
The aim of this research is to call the attention to the humid areas preservation for they are natural habitat with special dynamic and genesis and that they have been damaged by the gradual development of the use of the soil in the latest year. The upper basin of Araguaia river were chosen as an area study to follow systematically the development of Cerrado

23. Caracterização citogenética de populações alopátricas do gênero Hoplias (Characiformes, Erythrinidae), com enfoque nos grupos malabaricus e lacerdae
Erythrinidae represents a relatively small family of Neotropical fish, presenting a great geographical distribution. It is composed only by three genera, Hoplias, Hoplerythrinus and Erythrinus. The genus Hoplias is most widespread in the South American continent. Two great groups, H. malabaricus and H. lacerdae are described for the Southeast Brazil, showing

24. O ÍNDICE DE SUSTENTABILIDADE AMBIENTAL DO USO DA ÁGUA (ISA) COMO FERRAMENTA DE CONTRIBUIÇÃO ÀS POLITICAS PÚBLICAS DE DESENVOLVIMENTO E CONSERVAÇÃO NA BACIA DO RIO BACANGA, SÃO LUÍS/ MA. / INDEX FOR ENVIRONMENTAL SUSTAINABILITY OF WATER USE (ISA) AS A TOOL FOR CONTRIBUTION TO THE POLICIES PUBLIC DEVELOPMENT AND CONSERVATION IN BACANGA RIVER BASIN, SÃO LUIS / MA.
A hydrographic basin is a complex environmental system, resulting from the interrelations between the physical-natural and socioeconomic subsystems. Its identity as the unifying of environmental processes and human interference is leading to its adoption as a research unit. It allows from the analysis of the physical-chemical, biological and socioeconomic fa
