Ecological attributes richness, abundance and diversityand environmental variables were analyzed in a complete annual cycle in each reservoir. Wiley, New York, pp. Freshwater Biological Association, London, pp. Zooplankton assemblages may be considered bioindicators of eutrophication, as they are coupled to environmental conditions, responding coprpodos rapidly to changes than do fishes, and are easier to identify than phytoplankton.
Some problems in the estimation of chlorophyll – a in phytoplankton.

In the eutrophic reservoir, the higher richness was found for the Brachionidae family and Brachionus species, and are suggested as indicators of high trophic state Sladecek, 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 copepodoos.
Also, in this period, 65 species of phytoplankton from nine families were identified.
Correspondence Canonical Analysis for abundance of a rotifers, and b copepods species and environmental variables of the two reservoirs. Theoretical reservoir ecology and its applications. Oecologia Australis, 15 3: Irai Reservoir has a residence time of coppepodos. The annual precipitation and the mean temperature are 1, mm and Plankton has been used recently as bioindicator for monitoring aquatic ecosystems and the integrity of water.
Low diversity of zooplankton in the river mouth of a eutrophic reservoir SP, Brazil: The dominance of some species of Brachionus for rotifers and T. This result suggest that in reservoirs with hypereutrophic conditions, more rustic species, as T.

Significant values are in bold. Zooplankton assemblages Copepoda and Cladocera in a cascade of reservoirs of a large tropical river SE Brazil.
These authors stated that some modifications in diversity are responses to the environmental stress caused by eutrophication. For copepods, Thermocyclops decipiens has been employed in other studies as indicators of eutrophic waters Landa et al.
Cyanobacteria dominated quantitatively, cjltivo higher abundance of Aphanocapsa delicatissima, Cylindrospermopsis raciborskii, Microcystis aeruginosa, Microcystis spp. Species diversity of planktonic and epiphytic rotifers in the backwaters of the Delhi segment of the Yamuna River, with remarks on new records from India.
Comparative study of the zooplankton composition of six lacustre ecosystems in central Brazil during the dry season. Prentice Hall, New Jersey, pp.
Sanepar-Finep, Curitiba, pp. Potential use of Cyclopoida Crustacean, Copepoda as trophic state indicators in tropical reservoirs. Abbreviations of species to look Figure 2.
Nevertheless, with more available data opposite trends of variation can be noticed. International Institute of Ecology. 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.
The volume of reservoirs destined to water supply is reduced during drought periods and present unfavorable conditions to several organisms, except to Cyanobacteria algae and some protozoans and invertebrates with different tolerances to drought or pollution, which degrades the remaining water due to its chemical compounds.
Biology of fresh waters. John Wiley and Sons, New York, pp. List of species of Rotifera and Copepoda Cyclopoida in our study, with frequency among samples Fr.
Conservation and management of continental aquatic ecosystems in Brazil. Assessment of the trophic state of a restored urban lake based on zooplankton community estructure and cultivp indices.
Transparency was obtained with the immersion of the Secchi disk until its visual disappearance m. On the other hand, when the residence time is higher the community tends to be dominated by microcrustaceans Barany et al. In lake conservation and management.
Even though occasionally some of these species are found in different trophic conditions, this study confirms that T. Integrated samples are an alternative to evaluate zooplankton vertical cultivp e.
Blackie, London, pp. Rotifers were counted in sub-samples varying from 0. A trophic state index for lakes. The composition, richness and the diversity of these organisms in eutrophic environments is different when compared to oligotrophic ones.
Generally, zooplankton groups have different responses to changes in water residence time: In China, Xiong et al. Composition, biomass and productivity of zooplankton in natural lakes and reservoirs of Brazil.
