Effects of phosphorus and nitrogen amendments on the growth of Egeria najas

Aquatic Botany, 2007
Abstract 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 ...

Limnological effects of Egeria najas Planchon (Hydrocharitaceae) in the arms of Itaipu Reservoir (Brazil, Paraguay)

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.

An efficient Egeria najas-derived biochar supported nZVI composite for Cr(VI) removal: Characterization and mechanism investigation based on visual MINTEQ model

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.

Response of native Egeria najas Planch. and invasive Hydrilla verticillata (L.f.) Royle to altered hydroecological regime in a subtropical river

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 ...
