Environmental heterogeneity influences life-form richness and species composition but not species richness of aquatic macrophytes in tropical coastal rivers
(2020-01-01)
The coastal rivers of the São Paulo State in SE Brazil have different lengths and seawater influence. We evaluated whether: (1) environmental heterogeneity (EH) is associated with the species and life-form richness of ...
Estimating cyclopoid copepod species richness and geographical distribution (Crustacea) across a large hydrographical basin: comparing between samples from water column (plankton) and macrophyte stands
(Sociedade Brasileira de ZoologiaCuritiba, 2014-06)
Species richness and geographical distribution of Cyclopoida freshwater copepods were analyzed along the "La Plata" River basin. Ninety-six samples were taken from 24 sampling sites, twelve sites for zooplankton in open ...
Can a low concentration of an organophosphate insecticide cause negative effects on an aquatic macrophyte? Exposure of Potamogeton pusillus at environmentally relevant chlorpyrifos concentrations
(Pergamon-Elsevier Science Ltd, 2017-06)
The contamination of the aquatic environments with organophosphorus pesticides may affect non-target organisms. The aim of this study was to evaluate the toxic effects of the insecticide chlorpyrifos (CPF) at environmental ...
Interações macrófitas-invertebrados aquáticos: rede de interação e variação temporal
(Universidade Tecnológica Federal do ParanáSanta HelenaBrasilPrograma de Pós-Graduação em Recursos Naturais e SustentabilidadeUTFPR, 2022-02-25)
Macrophytes are important structural components of tropical aquatic ecosystems. They play crucial roles in the dynamics of these ecosystems and serve as storage and cycling of nutrients, food for various organisms, ...
Niche-breadth of freshwater macrophytes occurring in tropicalsouthern African rivers predicts species global latitudinal range
(Elsevier Science, 2016-09)
The study tested the hypothesis that measurement, using multivariate Principal Components Analy-sis (PCA), of the niche-breadth of river macrophyte species in southern tropical Africa, may predicttheir larger-scale ...
How water level management affects cladoceran assemblages in lakes lateral to a reservoir
(2016-01-01)
This study analysed the effects of induced water level depletion for macrophyte control in a tropical reservoir on the cladoceran fauna of two differentially connected lateral lakes. One lake, Pedra Branca, is located in ...
Comparing environmental impacts of native and introduced freshwater prawn farming in Brazil and the influence of better effluent management using LCA
(Elsevier B.V., 2015-07-01)
Concern about environmental impacts of aquaculture and its interaction with natural resources is increasing. Thus, it is important for new production systems to use practices that reduce environmental impacts, such as ...

A novel device with macrophytes and bio balls as a rehabilitation tool for small eutrophic urban ponds: a mesocosm approximation
(Elsevier, 2019-01)
During the last century, the human-derived impact on freshwater systems has been severe all around the world. Artificial eutrophication has an outstanding relevance in urban aquatic ecosystems and it is recognized as one ...
