Jorge Laco Portinho jorgeportinho gmail. Biology of fresh waters. Two small, shallow and polymictic reservoirs near to Curitiba city Parana State, Brazilwere studied. Palaeontological statistics software package for education and data analysis. The species that showed significant differences between reservoirs are shown in Table 2.
New morphological characters useful for the taxonomy of genus Copepoddos Copepoda, Cyclopoida. Physis, Buenos Aires, 58 A trophic state index for lakes. Ecological attributes richness, abundance and diversityand environmental variables were analyzed in a complete annual cycle in each reservoir.
Correlation coefficients r 2 and P value P of the environmental variables and Rotifera and Copepoda species through the Canonical Correspondence Analysis, using 1, permutations.
More details of Irai Reservoir can be found for zooplankton assemblages Serafim-Junior et al. Probably due the excessive eutrophication with intense algal blooms and other variables such reservoir morphometry, climate and altitude, Thermocyclops was present but was never dominant during the studied period.
Other species of cyclopoid copepods copepods become dominant in hypereutrophic environments, such as Metacyclops mendocinus, found in high abundance in Barra Bonita Reservoir, in Tiete River Zaganini et al.
Zooplankton especially crustaceans and rotifers as indicators of water quality. Rotifers and cyclopoids species can be selected due its contrasting abundances between reservoirs. The interaction was used to examine if differences among months in each reservoir were absent.

Zooplankton assemblage concordance patterns in Brazilian reservoirs. In central Brazil, one comparative study of the zooplankton composition of six lacustrine ecosystems, observed a tendency of decreasing diversity with increasing trophic level Starling, The diversity and equitability were calculated using the Past V.
Perspectives on reservoir limnology. Several studies provided lists of rotifer species that are indicative of different trophic states, among them good indicators of eutrophic conditions are Bra-chionus sp. Coppodos samples are an alternative to evaluate zooplankton vertical distribution e. In first variable, Acanthocyclops robustus and Tropocyclops prasinus were correlated with total phosphorus, water temperature, chlorophyll – aand total phytoplankton in the copelodos reservoir.
The effects of hydrobiology on plankton biomass in shallow lakes of the Pampa Plain. Despite the dominance of T. Species that showed higher differences between reservoirs were chosen.
The dominance of Brachionus for rotifers and Tropocyclops prasinus and Acanthocyclops robustus for copepods were indicative of eutrophic conditions.
Nevertheless, with more available data opposite trends of variation can be noticed. A minimum of individuals were counted per sample and density was expressed in individuals m Correspondence Canonical Analysis for abundance of a rotifers, and b copepods species and environmental variables of the two reservoirs.
For example, according to Paturej the Shannon-Weaver index of species diversity, for the whole zooplankton community, tends to decrease as a water body becomes more ucltivo. The annual precipitation and the mean temperature are 1, mm and On the other hand, transparency and conductivity were positively correlated with Thermocyclops decipiens and T.

Thus, it is important to obtain predictive water quality monitoring in urban reservoirs destined to water supply. Relations among planktonic rotifers, cyclopoid copepods, and water quality in two Brazilian reservoirs. The same is observed for some species of Metacyclops genera. During a cuktivo, monthly samplings were carried out in three stations in each reservoir.
