Heat budgets, thermal structure and dissolved oxygen in Brazilian reservoirs
(International Institute Ecology, 2014)
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 ...
Defining a fish bio-assessment tool to monitoring the biological condition of a cascade reservoirs system in tropical area
(Elsevier B.V., 2014-08-01)
We studied five tropical reservoirs in the cascade system of the Tiete River (State of Sao Paulo, Brazil) in order evaluate the suitability of a fish multimetric index (Reservoir Fish Assemblage Index-RFAI) as a bio-assessment ...
Trophic state index (TSI) and physico-chemical characteristics of a shallow reservoir in southeast Brazil
(2016-01-01)
This paper presents the trophic state index (TSI) and water physico-chemical characteristics of a shallow tropical reservoir located in southeast Brazil. It describes a study held over a hydrological and diurnal period, ...
Spatial and temporal heterogeneity in the Jurumirim Reservoir, São Paulo, Brazil
(1999-09-01)
Jurumirim is a large tropical reservoir with remarkable spatial gradients. This structure seems to be determined by a longitudinal gradient in the trophic conditions along the main axis of the reservoir. Nutrient-rich ...
Phytoplankton composition, dominance and abundance as indicators of environmental compartmentalization in Jurumirim Reservoir (Paranapanema River), São Paulo, Brazil
(Kluwer Academic Publ, 2000-07-01)
Patterns in the spatial and temporal composition, dominance and abundance of the phytoplankton community of the Jurumirim Reservoir (Brazil) were studied during one year at ten different sampling stations. The main ...

Selection of sites for establishing aquaculture parks, and estimation of fish production carrying capacity, for a tropical reservoir in South America
(2017-06-01)
Actions facilitating the reconciliation of multiple uses of a reservoir with electric power generation should be implemented so as to avoid conflicts and support the best development of the water resource. In view of the ...
