摘要: The dominance patterns of the main zooplankton groups depend on whether they are analysed by numerical density or dry weight. This fact is discussed in relation to trophic state system. Biomass planktonic crustaceans from Broa reservoir was For Argyrodiaptomus furcatus organic carbon also determined. Values 4.42 µg C ind.−1 and 6.83 were obtained for males females, respectively. Seasonal fluctuation species showed two peaks abundance: rainy season (summer), windy period (winter), these factors being thus principal controlling forces growth populations.
