Correlations between nutrient concentrations and zooplankton populations in a mesotrophic reservoir
1. A year‐round study was conducted in a mesotrophic reservoir to determine the dynamics of zooplankton populations as a function of food availability (edible phytoplankton), nutrient concentration, temperature and hydraulic regime. 2. Rotifer biomass was correlated with soluble reactive phosphorus...
