Cladocerans were not included in our studied because they not showed any correlation with water quality. Planktonic rotifers as indicators of lake trophy. Irai Reservoir has a residence time of days. Rotifers copepofos indicators of water quality.

Se escogieron aquellas especies que presentaron las mayores diferencias. Urban reservoirs have several social services and available environments used for fishing, recreation, tourism, and water supply, and are also submitted to many forces due to it is multiple uses, such as discharge of solid residues, shore degradation, punctual coopepodos non-punctual sources of phosphorus, sedimentation and intense urban occupation Tundisi et al.

Primary productivity in lakes and reservoirs is controlled by a set of physical, chemical and biological variables Thornton, The interpretation of ecological data; a primer on classification and ordination. Among copepods, only M. Zooplankton biomass and community structure in a Danube River floodplain system: The dominance of some species of Brachionus for rotifers and T. John Wiley and Sons, New York, pp.

Species diversity index for aquatic systems offers distinct possibilities for quantitatively evaluate the response of a community to pollution. Distribution of rotifers in North Island, New Zealand, and their potential use as indicator of lake trophic state. The composition, richness and the diversity of these organisms in eutrophic environments is different when compared to oligotrophic ones. The diversity and equitability were calculated using the Past V.

The two reservoirs have some similar morphometric characteristics, but contrasting trophic conditions, as shown in Table 1. 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.

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, Different water volumes were filtered in each reservoir for determining the abundance of zooplankton, because data comes from different projects.

A pesar de la dominancia de T. The nomenclature of the Rotifera: In China, Xiong et al. A close relationship among richness, diversity and total abundance of copepods was observed in the interaction between months and reservoirs, suggesting that reservoirs show distinct temporal variations according to the trophic state.

Proceedings, conference of primary productivity measurements in marine and freshwater. The annual precipitation and the mean temperature are 1, mm and In the eutrophic reservoir, in the first canonical variable, mainly Polyarthra remata, P. For copepods, Thermocyclops decipiens has been employed in other studies as indicators of eutrophic waters Landa et al. In Irai Reservoir, L of subsurface 30 cm water were filtered using a motor pump which is widely used to sample zooplankton, and in Rio Verde Reservoir, samples were obtained through vertical hauls filtering about L of water.

Zooplankton biomass in tropical reservoirs in southern Brazil. In both reservoirs, diversity and richness were higher at station 2, and abundance at station 1. World Agroforestry Centre Kenya, pp. Although the dominance of T.

Some problems in the estimation of chlorophyll – a in phytoplankton. Copepods were identified and quantified under optical microscope, in subsamples varying from 0.

These authors stated that some modifications in diversity are responses to the environmental stress caused by eutrophication.

For copepods, Tropocyclops prasinus dominated in the eutrophic reservoir, cope;odos Thermocyclops decipiens, T. Comparative study of the zooplankton composition of six lacustre ecosystems in central Brazil during the dry season. Correspondence Canonical Analysis for abundance of a rotifers, and b copepods species and environmental variables of the two reservoirs. On the other hand, transparency and conductivity were positively correlated with Thermocyclops decipiens and T.

The continental zooplankton is composed of rotifers, small crustaceans cladocerans and copepods and protozoans. Two small, shallow and polymictic reservoirs near to Curitiba city Parana State, Brazilwere studied.
