1. [PROVISIONAL] Genetic evidence for a species complex within the piranha Serrasalmus maculatus (Characiformes, Serrasalmidae) from three Neotropical River basins based on mitochondrial DNA sequences
Abstract Mitochondrial molecular markers (DNA sequences of D-loop, cytochrome b and cytochrome c oxidase I) were employed to characterize populations of the piranha Serrasalmus maculatus from Upper Paraná, Upper Paraguay and Tocantins River basins. D-loop sequences of S. maculatus population from Paraná-Paraguay River basin exhibited tandem repeats of shor

2. Mass balances of major solutes, nutrients and particulate matter as water moves through the floodplains of the Pantanal (Paraguay River, Brazil)
RESUMO Na Bacia do Alto Paraguai, formadora do Pantanal Mato-grossense, uma das maiores áreas úmidas do mundo, os rios fazem a conexão entre o planalto e a extensa planície de inundação. Agropecuária, potencial erosivo associado a desmatamento elevado, efluentes urbanos e dezenas de barramentos hidrelétricos no planalto podem alterar o transporte de

3. Genetic Variability of Brycon hilarii in a Repopulation Program
ABSTRACT Brycon hilarii, popularly called piraputanga in Brazil, is a species distributed throughout the whole basin of the river Paraguay. In recent years, the species has been on a repopulation program due to its remarkable decline as a wild species in the region. Assessment of the genetic diversity of broodstock and fingerling stocks in repopulation progr

4. Sub-regiões fitogeográficas da floresta atlântica entre as bacias dos rios São Francisco e Uruguai baseadas na análise dos padrões de distribuição espacial da flora arbórea e do clima / Phytogeographic subregions of the Atlantic Forests between São Francisco and Uruguay River basins based on the analysis of spatial distribution patterns of the tree flora and climate
The spatial variation in the composition of the tree flora of some Atlantic forest areas distributed in the East Atlantic basins, Southeastern and Southern Brazil, extended to Paraguay and Argentina, was investigated under four main aspects: (1) to evaluate the level of floristic differentiation of tropical and subtropical forests along their latitudinal, al

5. Modeling the potential distribution of the invasive golden mussel Limnoperna fortunei in the Upper Paraguay River system using limnological variables.
The invasive golden mussel, Limnoperna fortunei (Dunker, 1857), was introduced into the La Plata River estuary and quickly expanded upstream to the North, into the Paraguay and Paraná rivers. An ecological niche modeling approach, based on limnological variables, was used to predict the expansion of the golden mussel in the Paraguay River and its tributarie

6. Abiotic factors controlling the establishment and abundance of the invasive golden mussel Limnoperna fortunei.
Limnoperna fortunei (Bivalvia, Mytilidae), a freshwater bivalve native to Southern Asia, has been an invasive species in South America since 1991. It spread upstream in the La Plata basin reaching the Paraguay River in the vicinity of the Pantanal wetland, Brazil, around 1998. The role of abiotic factors in controlling establishment and abundance of this spe

7. Evolução e conversão de áreas de cana-de-açúcar na bacia do Pantanal.
A política de incentivo à produção de biocombustíveis vem nos últimos anos, construindo um novo cenário de investimentos no setor sucroalcooleiro, tendo maior foco na região Centro-Sul. Por se apresentar como uma área importante para conservação, a bacia do alto Paraguai, por conter o Pantanal, não foi incluída no Zoneamento Agroecológico da ca

8. Diversidade genética em Dourado (Salminus brasiliensis Curvier,1816), uma espécie de grande interesse comercial no Pantanal Mato-grossense
Salminus brasiliensis is a migratory fish which is distributed in all parts of the rio de la Plata Basin. The Dourado is called the king of the river. Its one of the most sought after fish by amateur and/or professional fishermen. However, in some regions it is considered to be a vulnerable species. Recent reports have shown the existence of some populations

9. Genetic variability of two populations of Pseudoplatystoma reticulatum from the Upper Paraguay River Basin
Catfishes of the genus Pseudoplatystoma are very important species due to both their high commercial value and their ecological role as voracious predators. They undertake lengthy migratory movements during their life-cycle, this including reproductive migration which occurs from October to December in the rainy season. In the present study, seven microsatel

10. Estudo floristico e fitossociologico de um trecho de mata ciliar do Rio Paraguai, Pantanal-MS, e suas relações com o regime de inundação
A floristic and phytosociological study was carried out in a galIery forest of the Paraguay river near Corumbá and Ladário - MS, Brazil. Structural aspects of the forest were correlated to the flooding of the river, and the dynamics and some caracteristics of dispersion of the species were evaluated. The floristic survey comprised an area of about 22 km al
