dc.description.abstractThe present work tested the food selectivity of the cladoceran Ceriodaphnia quadrangula (O. F. Muller, 1785) and its impact on competition outcome between Chlorella vulgaris Beijerinck, 1890 and Chlamydomonas globosa J. W. Snow, 1902. Freshwater green algae, Chlorella, have heavy cell walls and their size usually exceeds the lower limits of limb size of Ceriodaphnia. According to the optimal foraging theory, it is speculated that Ceriodaphnia would graze on the more exposed and relatively larger Chlamydomonas rather than on Chlorella, and this process would lead to small-sized Chlorella becoming a superior competitor in the presence of Ceriodaphnia. This work used Ceriodaphnia, Chlamydomonas globosa and Chlorella vulgaris to test this hypothesis. The grazing experiment showed that Ceriodaphnia preferred Chl. globosa to Ch. vulgaris, regardless of the concentration and relative abundance of these algae. The decrease in relative abundance of high-quality Chlamydomonas in Chlamydomonas-Chlorella assemblages did not diminish the grazing efficiency of Ceriodaphnia on this algal species, but increased the selectivity of small-sized cells of Chlorella. However, when the concentration of Chlamydomonas was extremely high, the grazing of Ceriodaphnia on Chlamydomonas decreased. In competition experiments, it was observed that the presence of Chlamydomonas restrained the growth potential of Chlorella; however, the introduction of Ceriodaphnia into the competing environment weakened this influence and to some extent enhanced the growth ability of Chlorella. The different densities of Ceriodaphnia had an obvious influence on the competition outcome between Chlamydomonas and Chlorella.en_US
