1. Caracterização da influência de sistemas frontais sobre a qualidade da água do reservatório de Itumbiara, GO, utilizando dados de sensoriamento remoto e dados in situ / Characterization of frontal systems influence on water quality of Itumbiara reservoir, GO, Brazil, using remote sensing and in situ data
In addition to human activities the water quality in reservoirs is influenced by weather and climate forcings that determine spatial and temporal variations in these systems. Conventional techniques for water quality monitoring require large time and fund investments. The synoptic view of large areas and high temporal frequency remote sensing data provides a

2. Relações tróficas e limnológicas no reservatório de Itaipu: uma análise do impacto da biomassa pesqueira nas comunidades planctônicas / Trophic and limnological interactions in the Itaipu reservoir: an analysis of the impact of the fishing biomass in the planktonic communities
Many experimental studies contributed for the development of the theory of the lacustrine food web, disclosing the important paper of the fish, for decades ignored by the limnology. These studies, in its majority, had been developed in Europe and North America and the generality of the hypotheses supporting the theory was not tested yet in subtropical and tr

3. Aspectos limnológicos e sanitários de uma lagoa costeira no litoral leste do Ceará - lagoa do Batoque / Limnological and sanitary aspects of a coastal lagoon in the eastern coast of Ceará lagoa do Batoque
The water quality of Batoque lagoon, a coastal lagoon located along the eastern shoreline of the state of Ceará, Brazil, was characterized by means of monthly samplings from May to November 2005 to obtain dry-season (May-Jun) and wet-season (Aug-Nov) data. Additionally, two nycthemeral (24hr.) samplings were performed in July and December to observe daily v

4. Limnologia do rio Uberaba (MG) e a utilização de macroinvertebrados bentônicos como bioindicadores das modificações ambientais / Limnology of Uberaba river and using of benthic macroinvertebrates as bioindicator of environmental changes
Lotic systems are considered opened and one-way energy flux systems. In these cases, the intense relationship with adjacent terrestrial environment renders rivers ecological conditions a reflex of transformations occurred at its watershed. The present study aimed to profile an Uberaba river ecological features as a function of the watershed main uses. Limnol

5. Composição de rotífera em corpos d água da bacia do rio Tietê São Paulo, Brasil.
Rotifera composition in four Units of Management of Water Resources of Tietê River, in São Paulo State, was studied. Samples were obtained using a 35m plankton net pulled, horizontally and vertically, through limnetic and littoral regions and, afterwards, fixed with 4% formalin. One hundred and ninety nine taxa were identified. These belong to 23 families
