Dispersion patterns of zooplankton in two waste stabilization ponds

Abstract

The dominant zooplankters in waste stabilization ponds at Gumeracha were contagiously distributed on both small and gross scales. Individuals were never randomly distributed on a scale defined by the sampling unit. Overall patchiness of littoral species was more pronounced in the presence of high standing crops of aquatic macrophytes. Other possible causes of contagion in zooplankters are briefly discussed.
