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 ...

Invasion of the dinoflagellate Ceratium furcoides (Levander) Langhans 1925 at tropical reservoir and its relation to environmental variables
(REVISTA BIOTA NEOTROPICACAMPINAS, 2012)
Dinoflagellates of the genus Ceratium are chiefly marine but there are rare occurrences in freshwater. In this study we analyze the invasion and progressive establishment of Ceratium furcoides, an exotic species, in the ...

Phytoplankton, trophic state and ecological potential in reservoirs in the State of São Paulo, BrazilFitoplâncton, estado trófico e potencial ecológico em reservatórios do estado de São Paulo, Brasil
(2019-01-01)
This study evaluated the ecological potential of reservoirs in the Brazilian state of São Paulo, having phytoplankton as a biological quality element. Integrated water column sampling was carried out in the dam, and in the ...
A estrutura da comunidade de macro-invertebrados bentônicos em três represas do médio rio Tietê (SP), com ênfase nas espécies exóticas Melanoides tuberculata (Gastropoda, Thiaridae) e Corbicula fluminea (Bivalvia, Corbiculidae)
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERN, 2006-02-24)
The reservoirs are artificial ecosystems constructed by the man and attend to the multiple
uses. The reservoir provokes alterations in the aquatic ecosystem, causing modifications in
the chemical and physical composition ...
Aquatic macrophytes of Itaipu Reservoir, Brazil: Survey of species and ecological considerations
(1999-12-01)
In a survey of the aquatic macrophytes of the Itaipu Reservoir, we identified 62 taxa in 25 families and 42 genera. The highest number taxa was observed for the emergent macrophytes (40 taxa). Reduced fluctuation in water ...
