Composition and abundance of zooplankton in the limnetic zone of seven reservoirs of the Paranapanema River, Brazil
The species composition and abundance of the zooplankton community of seven reservoirs of the Paranapanema River, located between 22º37'-23º11'S and 48º55'-50º32'W, were analysed over four periods, in the year of 1979. The zooplankton community was composed of 76 species of Rotif...
