The microbiome of brazilian mangrove sediments as revealed by metagenomics. Author(s): ANDREOTE, F. D.; JIMENEZ, D. J.; CHAVES, D.; DIAS, A. C. F.; LUVIZOTTO, D. M.; DINI-ANDREOTE, F.; FASANELLA, C. C.; VARON LOPEZ, M.; BAENA, S.; TAKETANI, R. G.; MELO, I. S. de ABSTRACT: Here we embark in a deep metagenomic survey that revealed the taxonomic and potential metabolic pathways aspects of mangrove sediment microbiology. The extraction of DNA from sediment sample... ... Repository: BDPA Publication year: 2012
Trace metals concentrations in mangrove sediments of Sepetiba Bay (Rio de Janeiro, Brazil): microwave assisted digestion with nitric acid and aqua regia. Author(s): SOUZA, P. S. A. de; MARQUES, M. R. C.; SOARES, M. L. G.; PEREZ, D. V. Mangrove sediments have a great capacity to accumulate trace metals that can be remobilized thus contaminating the water and biota. Concentrations of trace metals (Cu, Ni, Pb and Zn) in mangrove sedim... ... Repository: BDPA Publication year: 2012
Assessment of suspended sediment discharge in the Purus River basin, Brazil. Author(s): LATUF, M.; AMARAL, E. F. do Having a river basin as the study site, it is of fundamental importance to comprehend the sediment dynamics of river systems, in order to diagnose and understand them, aiming to carry out predictions.... ...

Sediment infill of tropical floodplain lakes: rates, controls, and implications for ecosystem services. Author(s): LO, E. L.; YEAGER, K, M.; BERGIER, I.; DOMINGOS-LUZ, L.; SILVA, A.; MCGLUE, M. M. Shallow lakes in tropical floodplains provide significant ecosystem services that can be altered by natural and anthropogenic forces. Despite their importance, little is known about the infill pattern... ... Repository: BDPA Publication year: 2022
Evaluation of the QuEChERS method and gas chromatography-Mass spectrometry for the analysis pesticide residues in water and sediment. Author(s): BRONDI, S. H. G.; MACEDO, A. N.; VICENTE, G. H. L.; NOGUEIRA, A. R. de A. A method for the determination of pesticide residues in water and sediment was developed using the QuEChERS method followed by gas chromatography ? mass spectrometry. The method was validated in terms... ... Repository: BDPA Publication year: 2011
Further development of small hydropower facilities will significantly reduce sediment transport to the Pantanal wetland of Brazil. Author(s): FANTIN-CRUZ, i.; OLIVEIRA, M. D. de; CAMPOS, J. A.; CAMPOS, M. M. de; RIBEIRO, L. de S.; MINGOTI, R.; SOUZA, M. L. de; PEDROLLO, O.; HAMILTON, S. K. Small hydropower (SHP) facilities, which are defined by installed capacities <10?50 MW, are increasingly being built around the world. SHPs are viewed as less environmentally harmful than larger dams,... ... Repository: BDPA Publication year: 2020
Sediment yield modeling using an alternative environmental scenario in northwestern Rio de Janeiro - Brazil. Author(s): MARCHIORO, E.; FERNANDES, N.; MACEDO, J.; BHERING, S.; GONCALVES, A.; PRADO, R. The northwestern Rio de Janeiro (RJ-Brazil) area has been going through deep transformations in its soil use and occupation, which has contributed to increased sediment yield and changes in the soil-w... ...
