Phytoplankton assemblages in a reservoir cascade of a large tropical - subtropical river (SE, Brazil)
(Instituto Internacional de Ecologia, 2010-10-01)
As assembleias fitoplanctônicas de oito reservatórios do rio Paranapanema foram estudadas durante dois anos consecutivos. Chlorophyceae e Bacillaryophyceae foram os grupos dominantes em riqueza. O elevado número de táxons ...

Modelagem da circulação de um reservatório tropical polimítico.
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERN, 2003-11-06)
Environmental pulses occur very often in warm polymitic reservoirs and, together with
shifts in the operational rules, lead to large internal temporal variability. The focus of this
work was: (i) to evaluate the main ...
Seasonal dynamics of fishery at the Piracicaba River (Brazil)

A satellite-based investigation into the algae bloom variability in large water supply urban reservoirs during COVID-19 lockdown
(2021-08-01)
Here we report the first case study of the significant algae blooming in large reservoirs in relation to the COVID-19 lockdown in Sao Paulo, Brazil. Chlorophyll-a (Chl-a) and phycocyanin (PC) concentrations were estimated ...
Secondary production and biomass of Cladocera in marginal lakes after the recovery of their hydrologic connectivity with a tropical river
(2010)
Secondary production and biomass of Cladoceran populations were studied in two marginal lakes whose connections to atropical river were re-established after a prolonged drought period. This study investigates the process ...

Modeling energy flow in a large Neotropical reservoir: a tool do evaluate fishing and stability
(Universidade Estadual de Maringá, 2006)
Recently, there is an increasing perception that the ecosystem approach gives important insights to support fisheries stock assessment and management. This paper aims to quantify energy flows in the Itaipu Reservoir (Brazil) ...
