Journal ArticleDOI
Microcystins (cyanobacteria hepatotoxins) bioaccumulation in fish and crustaceans from Sepetiba Bay (Brasil, RJ)
Valéria Freitas de Magalhães,Marcelo Manzi Marinho,Patrícia Domingos,Ariclécio Cunha de Oliveira,Simone M. Costa,Luiz Otávio Azevedo,Sandra M.F.O. Azevedo +6 more
TL;DR: It was verified that 19% of the animals' samples were above the limit recommended by WHO for human consumption, which refers to healthy adult, and data demonstrate that, although in low concentrations, there is already a contamination of fish and crustaceans from Sepetiba Bay.
Book ChapterDOI
Cyanoprokaryote assemblages in eight productive tropical Brazilian waters
Vera L. M. Huszar,Lúcia H. S. Silva,Marcelo Manzi Marinho,Patrícia Domingos,Célia Leite Sant’Anna +4 more
TL;DR: In this article, the main driving forces of the dominance of non-N2-fixing organisms in eight very productive Brazilian lakes are described and the main drivers of their dominance are considered, and the relative abundance of blue-greens is shown to have been positively related to temperature, but not to pH or total-P, and negatively associated with light, mixing, NO3 but not with NH4.
Journal ArticleDOI
The effects of water retention time and watershed features on the limnology of two tropical reservoirs in Brazil
Maria Carolina S. Soares,Marcelo Manzi Marinho,Vera L. M. Huszar,Christina W. C. Branco,Sandra M.F.O. Azevedo +4 more
TL;DR: In this article, physical and chemical variables were measured at four sampling sites in two reservoirs in southern Brazil, from June 2002 to June 2003, with the goal of investigating how these factors influence the limnology of tropical reservoirs.
Journal ArticleDOI
Controlling cyanobacterial blooms through effective flocculation and sedimentation with combined use of flocculants and phosphorus adsorbing natural soil and modified clay
Natalia Pessoa Noyma,Leonardo de Magalhães,Luciana Lima Furtado,Maíra Mucci,Frank van Oosterhout,Vera L. M. Huszar,Marcelo Manzi Marinho,Miquel Lürling +7 more
TL;DR: The authors' data showed that buoyant cyanobacteria could be flocked and effectively precipitated using a combination of PAC or chitosan with LMB or LRS and the soluble reactive P adsorbing capacity of both LMB and LRS under oxic and anoxic conditions.
Journal ArticleDOI
Changes in species composition during annual cyanobacterial dominance in a tropical reservoir: physical factors, nutrients and grazing effects
Maria Carolina S. Soares,M. I. de A. Rocha,Marcelo Manzi Marinho,Sandra M.F.O. Azevedo,Christina W. C. Branco,Vera L. M. Huszar +5 more
TL;DR: The present study showed that under high and constant input of nutrients, other factors, especially physical variables, present a more plausible explanation to promote changes in species composition.
