Fisheries in large tropical reservoirs in South America
(1996-12-01)
The present status of large reservoir fisheries and their management in large reservoirs in South America are reviewed. There is a brief discussion about reservoir typology, and how most of it is inappropriate to fish. ...
Spatial distribution, bioavailability, and toxicity of metals in surface sediments of tropical reservoirs, Brazil
(2018-04-01)
Depending on the environmental conditions, surface sediments can retain all the contaminants present and provide a record of the anthropic activities affecting the aquatic environment. In order to analyze the impacts on ...
Increases in microcrustaceans (Cladocera and Copepoda) associated with phytoplankton peaks in tropical reservoirs
(Int Soc Tropical Ecology, 2016-09-01)
We studied the interactions between microcrustaceans and phytoplankton in storage and run-of-river tropical cascade reservoirs in Brazil by performing comparisons on a spatial-temporal scale and non-parametric correlations. ...
Heat budgets, thermal structure and dissolved oxygen in Brazilian reservoirs
(International Institute Ecology, 1999-01-01)
A comparison of the thermal regime and oxygen distribution patterns of some Brazilian reservoirs was made. A strong latitudinal dependence of surface temperature, annual mean and annual range was found. Except for Tucurui ...
Influence of watershed activities on the water quality and fish assemblages of a tropical African reservoir
(Universidad de Costa Rica, 2009)
Phosphorus fractionation in sediments of tropical semiarid reservoirs
(Elsevier BV, 2018-04-01)
Empirical model comparison and model tuning for estimating aCDOM in a tropical reservoir in Brazil
(2015-11-10)
The aim of this work was to fit an empirical model for estimating the Colored Dissolved Organic Matter (CDOM) absorption coefficient (aCDOM) at 412 nm [aCDOM(412)] and 443 nm [aCDOM(443)], in Itumbiara reservoir (Goiás ...
