“…The total zooplankton biomass estimated for Ponte Nova corresponds to other environments with similar trophic conditions, such as the Carioca Lake, Doce River and Lobo reservoir, for which values of 10.9 and 11 to 16 mgDW.m -3 were estimated, respectively, by Matsumura-Tundisi & Tundisi (1986) and Matsumura-Tundisi et al (1989).…”

“…As for calanoid copepods, the dry weight of Argyrodiaptomus furcatus was estimated earlier by Matsumura-Tundisi et al (1989); however, this study adds an estimate of the dry weight of Odontodiaptomus paulistanus and of three Notodiaptomus species.…”

“…A comparative approach is difficult due to the use of different methodologies. Matsumura-Tundisi et al (1989) and Melão (1997) estimated dry weights of microcrustaceans in the Broa reservoir (SP) and in the Lagoa Dourada reservoir (SP) using a microbalance. Wisniewski (1998) obtained data from the literature for the Barra Bonita reservoir.…”

“…The species of the zooplankton community display a wide array of sizes, so numerical population densities do not always provide useful information (Matsumura-Tundisi et al, 1989), making comparative studies of tropical and temperate reservoirs or different hydrographic basins and trophic states difficult.…”

This paper reports on a study involving an estimate of the biomass of rotifers, cladocerans, and cyclopoid and calanoid copepods found in reservoirs in different trophic conditions, comparing and relating numerical density data and pointing out differences between the dry and rainy seasons. In terms of numerical densities, both reservoirs were dominated by rotifers, although cladocerans represented a higher biomass in the oligotrophic environment in both seasons. In the eutrophic environment, higher biomass values were found for cyclopoids during the dry season and for cladocerans during the rainy one. Different biomass patterns were observed relating to both the trophic conditions and the rainy and dry seasons.Keywords: biomass, zooplankton, trophic state, Alto Tietê Basin. RESUMO Biomassa de organismos zooplanctônicos em represas de diferentes condições tróficas do Estado de São Paulo, BrasilEste trabalho descreve um estudo sobre a determinação dos valores de biomassa de rotíferos, cladóceros, copépodos calanóides e ciclopóides em represas de diferentes estados tróficos, com o objetivo de comparar e relacionar com dados de densidades numéricas, considerando os períodos chuvoso quente e estiagem frio. Verificou-se que, embora rotíferos tenham dominado numericamente em ambas as represas, em termos de biomassa os cladóceros predominaram no ambiente oligotrófico, em ambos os períodos considerados. No ambiente eutrófico, copépodos ciclopóides predominaram no período estiagem frio, e cladóceros, no chuvoso quente, evidenciando padrões diferenciados de biomassa tanto em relação às condições tróficas quanto aos períodos chuvoso e seco.Palavras-chave: biomassa, zooplâncton, estado trófico, Bacia do Alto Tietê.

Zooplankton biomass in tropical reservoirs in southern Brazil

et al. 2006

In order to test the hypothesis that zooplankton biomass distribution (total and taxonomic groups) was influenced by the nutrient concentration and primary productivity distribution in three tropical reservoirs, subsurface samples were taken in the fluvial, transitional and lacustrine regions of three reservoirs (oligotrophic, mesotrophic and eutrophic) in southern Brazil (Paraná State) in March and September 2002. Zooplankton biomass ranged from 0.04 to 264.47 mg DW m -3 . Higher biomass values were observed for cladocerans (73.60%; 0.01-259.86 mg DW m -3 ), followed by copepods (22.05%; 0.01-69.69 mg DW m -3 ) and rotifers (4.35%; 0.01-11.52 mg DW m -3 ). In general, the total zooplankton, rotifer, cladoceran and copepod biomass, and chlorophyll-a and total nutrient concentrations showed a similar longitudinal distribution within the reservoirs. Total zooplankton, rotifer and cladoceran biomass were related to the chlorophyll-a concentration, and zooplankton biomass was related to the total phosphorus distribution. This may have been due to the significant multicolinearity between the chlorophyll-a and total phosphorus concentrations. Cyanobacteria influenced the taxonomic group biomass results by interfering with the filter feeding in larger zooplankton species, which favoured the dominance of smaller species. As regards the longitudinal distribution of copepod biomass, cyanobacteria biomass determined the displacement of the microcrustaceans to the fluvial region of Iraí Reservoir. Our results supported the hypothesis formulated and the primary productivity was the major predictor of the zooplankton biomass distribution in the reservoirs.
