Aquatic Botany, 2004
Abstract The ability of two submerged freshwater macrophyte species, Egeria najas Planchon and Egeria densa Planchon to use HCO 3 − as a source of inorganic carbon for photosynthesis was assessed by a pH drift experiment. The pH values and different HCO 3 − concentrations were set up at the beginning of the experiments, in low and high ...

Aquatic Botany, 2005
Abstract Incidence data of two native submerged aquatic macrophytes ( Egeria najas Planch. and Egeria densa Planch.) were obtained in eight arms of a large (1350 km 2 ) subtropical reservoir (Itaipu Binacional Reservoir, Brazil-Paraguay). Environmental variables were measured simultaneously.

Powder Technology, 2021
Abstract A novel Egeria najas driven-biochar was activated by loading ferric chloride onto surface (FeCl3@EN-BC). The synthesized composite was evaluated for its physicochemical properties and Cr(VI) adsorption behavior and mechanism. The result of SEM showed that the modified biochar is less porous than raw Egeria najas biochar, but loaded with γ ...

Effects of phosphorus and nitrogen amendments on the growth of Egeria najas
Aquatic Botany, 2007Abstract The effect of nutrient addition on the growth of E. najas was evaluated in a dose response experiment using sand amended with phosphorus (P) and nitrogen (N), and in enrichment trials with N and P amendments to natural sediments. Plants, water and sediment came from lagoons of the Upper Parana River Floodplain and from Itaipu Reservoir ...

Limnology, 2009
The limnological effects resulting from the metabolism of Egeria najas Planchon (Hydrocharitaceae) were evaluated in the arms of the Itaipu Reservoir (Brazil). Due to local population decline in biomass and coverage, decomposition was the main process that accounted for the observed limnological changes.

Environmental Research, 2020
Egeria najas is a submerged aquatic plant, and the literatures on resourcification of submerged aquatic plant biochar remain limited. Until now, there has been no study on submerged aquatic plant biochar supported nZVI that is widely applied for removal of diversified contaminants in solution.

Aquatic Botany, 2010
Abstract Egeria najas Planch. is the dominant native submersed macrophyte of the Upper Parana River in Brazil, while Hydrilla verticillata (L.f.) Royle has recently invaded this area. From January 2006 to December 2007, comprising two annual flood cycles, we conducted monthly surveys at two river stations and two lakes connected to the river ...
