Does the evasive behavior of Hexarthra influence its competition with cladocerans?

  title={Does the evasive behavior of Hexarthra influence its competition with cladocerans?},
  author={Anupama Kak and T. Ramakrishna Rao},
We tested the hypothesis that evasive movements by Hexarthra mira reduce adverse effects of interference competition with cladocerans permitting coexistence. To do this we studied the population growth of Hexarthra mira and two non-evasive Brachionus species in the presence of one of either two cladocerans (Daphnia similoides, Ceriodaphnia cornuta) at three food (Chlorella) levels (0.5, 2 and 4 × 106 cells ml-1) at 25°C. The non-evasive, but larger-sized B. calyciflorus was suppressed by D… CONTINUE READING
