Macrophytes in tropical shallow lakes: An important food item to benthic entomofauna or an underused resource?
(2019-01-01)
Although macrophytes are known to increase benthic diversity in lakes, the importance of this resource as food for the insects living at the bottom of these ecosystems are still poorly understood. This study assessed the ...
The contrasting roles of aquatic fungi and oomycetes in the degradation and transformation of polymeric organic matter
(2019)
Studies on the ecological role of fungi and, to a lesser extent, oomycetes, are receiving increasing attention, mainly due to their participation in the cycling of organic matter in aquatic ecosystems. To unravel their ...
In situ application of a cellulose bag and an ion exchanger for differentiation of labile and inert metal species in aquatic systems
(Springer Heidelberg, 2008-02-01)
This work involved the development and application of a new analytical procedure for in-situ characterization of the lability of metal species in aquatic systems by using a system equipped with a diffusion membrane and ...

Extração de matéria orgânica aquática por abaixamento de temperatura: Uma metodologia alternativa para manter a identidade da amostra
(2003-03-01)
In this work was developed an alternative methodology to separation of aquatic organic matter (AOM) present in natural river waters. The process is based in temperature decreasing of the aqueous sample under controlled ...

In situ differentiation of labile/inert metal species in Brazilian tropical rivers by means of a time-controlled batch-procedure based on TEPHA resin
(Taylor & Francis Ltd, 2011-01-01)
The present study deals with a new analytical procedure based on a cellulose diffusion membrane and immobilised tetraethylene-pentamine-hexaacetate chelator (DM-TEPHA) for an in situ differentiation of labile and inert ...

Use of Eichhornia crassipes dry matter as organic substrate for germination and initial growth of corn
(Univ Juarez Autonoma Tabasco, Direccion Investigacion & Posgrado, 2018-01-01)
The objective was to evaluate the potential use of the dry matter of the aquatic macrophyte (Eichhornia crassipes) as a substrate for germination and initial growth of corn (Zea mays L.). The experimental design was ...
