(Universidade Federal de São Carlos, 2010-06-01)
This work aimed evaluates the Alto Jacaré-Guaçu rivers basin quality through physical, chemical and biological and ecotoxicological analysis. Samples of water and sediment were collected in April /07; July/07; October/07 ...
Caracterização limnológica e análise da comunidade de macro-invertebrados bentônicos em um trecho da sub-bacia do alto Rio São Francisco (MG, Brasil)
(Universidade Federal de São Carlos, 2010-03-09)
In lotic environments, the benthic fauna is generally well developed and constitutes a community of great importance in the functioning of these ecosystems. The benthic macroinvertebrates participate in food chains, ...

Evaluation of quality and quantity of water contributes to the strategic decisionmaking policies and techniques to ensure the potential use of this resource for agriculture, industry, animal watering and for human consumption. ...
Efeitos de variáveis físicas e químicas na decomposição de recursos vegetais terrestres alagados em reservatórios
(Universidade Federal de São Carlos, 2011-06-08)
Reservoirs provide many benefits (e.g. recreation, water supply, electricity production) to human populations. However, the damming of a water body changes the characteristics from lotic to lentic environment. These changes ...
