1. Forecasting the impact of an invasive macrophyte species in the littoral zone through aquatic insect species composition
ABSTRACT Invasive macrophytes threaten freshwater ecosystem biodiversity. We analyzed the impact of the invasive white ginger lily (Hedychium coronarium J. König, Zingiberaceae) on aquatic insect assemblages living in the littoral zone of a tropical reservoir. We took aquatic insect samples in the littoral zone on four main vegetal profile banks: white ging

2. Desempenho de tanques vegetados em um ecossistema engenheirado para tratamento descentralizado de esgotos domiciliares na Ilha Grande, RJ / Performance of vegetated tanks in an engineered ecosystem for decentralized treatment of sewage in Grande Island, RJ
The lack of appropriate infrastructure for sewage collection and treatment affects several communities living under unhealthy conditions in coastal areas and in insular systems in Rio de Janeiro State. The objective of this study was to assess the performance of an engineering ecosystem for the descentralized treatment of domestic wastewater located at the C

3. BioacumulaÃÃo de Ãons de Pb+Â na macrÃfita Salvinia auriculata / Of the lead ions bioaccumulation process by living aquatic macrophytes Salvinia auriculata
In this work was carried out a study of the lead bioaccumulation process by living aquatic macrophytes Salvinia auriculata. Initially, they were performed toxicological and growing tests in order to determine the non-toxic lead concentration limits and the minimum amount of biomass for the lead uptake experiment duration. The bioaccumulation experiment was p

4. Hexavalent chromium detoxification by living aquatic macrophites root-based biosorption using high resolution x-ray fluorescence / Estudo da reduÃÃo de Cr(VI) usando espÃcies de macrÃfitas aquÃticas vivas pela tÃcnica de fluorescÃncia de raios-X de alta resoluÃÃo
Neste trabalho foi feito o experimento de bioacumulaÃÃo do cromo trivalente e hexavalente por trÃs espÃcies de macrÃfitas aquÃticas: Salvinia auriculata, Pistia stratiotes e Eicchornia crassipes, visando verificar a ocorrÃncia do processo de reduÃÃo do Cr(VI) durante a biossorÃÃo. Previamente, um teste de especiaÃÃo de cromo baseado em extraÃÃ

5. AvaliaÃÃo do potencial de biossorÃÃo dos Ãons Cd (II), Cu (II) e Zn (II) pela macrÃfita Egeria densa / Biosorption potential study for Cd (II), Cu (II) and Zn (II) by aquatic macrophytes Egeria densa
In the present work has been studied the metallic ion removal from aqueous solutions using the non-living aquatic macrophytes Egeria densa as biosorbent in order to assess its potential on cadmium, cuprum and zinc ions adsorption experiments. For this purpose, several adsorption tests were performed by duplicate in order to determine the optimal experimental

6. Lead bioaccumulation kinetic by living aquatic macrophytes Pistia stratiotes / CinÃtica de bioacumulaÃÃo do Ãon Pb+Â na macrÃfita aquÃtica Pistia stratiotes
In the present work the lead uptake onto a living free floating aquatic macrophyte Pistia stratiotes was investigated. The bioaccumulation mechanism were applied to understand the metal uptake by the autochthonous free floating Pistia, common in ponds and shallow lakes from southern Brazilian states from a hydroponics solution. The experiment was performed u

7. Gastrópodes e outros invertebrados bentônicos do sedimento litorâneo e associados a macrófitas aquáticas em açudes do semi-árido paraibano, nordeste do Brasil.
The Northeastern region in Brazil is characterized by long dry seasons, and the dams are very important to the people living in this region. In this work two dams in the semiarid of Paraiba State were studied to evaluate the quality of the water for human consumption, through the analysis of the benthonic community in the sediment and associated to aquatic m

8. Plantas hospedeiras de cornops aquaticum (Bruner) (Orthoptera : Acrididae) no Pantanal de Pocone-MT
The grasshopper Cornops aquaticum lives permanently on aquatic macrophytes in floodplains of tropical South America. Its host plants and its feeding preference were determined by means of field observations, crop analysis and feedings tests in the laboratory. Macrophytes were sampled and their petiols were examined for potential egg deposition in order to re

9. Annual Cycle of Bacterial Secondary Production in Five Aquatic Habitats of the Okefenokee Swamp Ecosystem †
Rates of bacterial secondary production by free-living bacterioplankton in the Okefenokee Swamp are high and comparable to reported values for a wide variety of marine and freshwater ecosystems. Bacterial production in the water column of five aquatic habitats of the Okefenokee Swamp was substantial despite the acidic (pH 3.7), low-nutrient, peat-accumulatin
