Abstract
Nitrogen fixation (acetylene reduction) by Aulosira and Anabaena in samples of flooded soil was reduced by Cypris sp. The number and biomass of this ostracod increased in the flooded soil when the animals were provided with Aulosira, Calothrix and Tolypothrix tenuis but not Anabaena. The decline in biomass of Aulosira was prevented by the addition of ethyl parathion to the floodwater. The predatory action was affected by temperature, and the optimum temperatures for reduction in biomass of the four blue-green algae (cyanobacteria) were different. Established populations of Aulosira. Calothrix and T. tenuis were more resistant to predation by Cypris sp. than developing populations.
