“…Because of its unique features, this reach of the Upper Paraná River floodplain has been the subject of many studies since 1980. These studies have focused on ecologic and taxonomic aspects including the various communities of phytoplankton [6,7], zooplankton [8], periphyton [9,10], benthic macroinvertebrates [11,12], ichthyofauna [13,14], aquatic macrophytes [15,16] and birds [17,18] and on the geomorphologic [19,20] and hydrologic aspects of the area [21].…”

The aim of this study was to investigate the temporal evolution of the supply of chemical elements to the Upper Paraná River floodplain and identify trends in the geochemistry of its drainage basin. The primary factor that regulates the supply of chemical elements of the Upper Paraná River floodplain is the flood pulse, which can be magnified by the El Niño-Southern Oscillation. Garças Pond is affected by agriculture, urbanization, discharge of industrial effluents and hydroelectric power production activities. Patos Pond is affected by sugarcane burning, gold mining, agriculture and urbanization.

The variation in energy in the muscles of the most representative fish species from three Neotropical Reservoirs was investigated to determine the effect of the reproductive process on the amount of energy allocated and a possible relationship between the general welfare of the species and their caloric content. Significant differences were detected between the sexes and among the stages of gonad maturity. In general, the variation in energy in the muscles indicate to be a function of the reproductive cycle. In most examined species, females presented the highest caloric values, reflecting physiological differences in their use of energy, relative to the reproductive process. However, there was no significant correlation between caloric values and the condition factor of any species. Significant differences in the caloric content and condition factor were identified in each species belonging different trophic groups, indicating an effect of food quality on the amount of energy stored in the muscles. We conclude that the analyzed species presented a similar pattern of variation in energy, but that this was not reflected in their condition. In addition, an effect of reproduction and feeding habit on energy allocation was observed in both sexes.Foi investigada a variação da energia nos músculos das espécies de peixes mais representativas de três reservatórios neotropicais, para determinar o efeito do processo reprodutivo na quantidade de energia alocada e uma possível relação entre o bem-estar geral das espécies e seu conteúdo calórico. Foram detectadas diferenças significativas entre os sexos e os estádios de maturidade gonadal. Em geral, a variação da energia nos músculos demonstra ser dependente do ciclo reprodutivo. Na maioria das espécies estudadas, as fêmeas apresentaram os maiores valores calóricos, refletindo as diferenças fisiológicas no uso de sua energia, em relação ao processo reprodutivo. No entanto, não houve correlação significativa entre os valores calóricos e o fator de condição as espécies estudadas. Diferenças significativas do conteúdo calórico e no fator de condição foram identificadas em cada espécie pertencente aos diferentes grupos trófcos, indicando um efeito de qualidade alimentar sobre a quantidade de energia armazenada nos músculos. Conclui-se que as espécies analisadas apresentaram um padrão semelhante de variação de energia, mas que isso não se refletiu em sua condição. Além disso, um efeito da reprodução e hábito alimentar, sobre a alocação de energia, foi observado em ambos os sexos.
