Zooplankton richness, abundance and biomass of two hypertrophic shallow lakes with different salinity in central Argentina Biota Neotropica
Echaniz,Santiago Andrés; Vignatti,Alicia María; Cabrera,Gabriela Cecilia; Paggi,Susana Beatriz José de.
The zooplankton of lakes is controlled by biological and physico-chemical parameters. Among the former, predation by fish can determine the replacement of large-sized species by small-sized ones and among the latter, salinity exerts negative effects on richness and abundance. Since it has been suggested that saline lakes without fishes have higher zooplankton biomass than low salinity ones, the aim of this study was to determine the richness, abundance and biomass of zooplankton in two lakes with different salinity and test the hypothesis that in the presence of zooplanktivorous fishes and at equal concentrations of nutrients and chlorophyll-a, saline lakes have higher biomass than those with low salinity. The study was conducted in two shallow lakes of...
