Zooplankton density and species diversity during spring and autumn for the four identified habitat types H – helophyte zone; P – pleustophyte zone; M – mixed vegetation zone (pleustophytes, nymphaeids, and elodeids); O – open water zone. The bars represent an average of 3 replicates (±SD). Letters above the bars indicate statistically different mean values.
