The effect of bacteria on interspecific relationships between the euryhaline rotifer Brachionus rotundiformis and the harpacticoid copepod Tigriopus japonicus

摘要: Inconsistent results have been obtained on the population growth of Brachionus rotundiformis and Tigriopus japonicus, when from single-species two-species mixed cultures are compared. Bacteria was not regulated in these experiments, which could be cause for this. In order to test this possibility, we conducted similar experiments under axenic synxenic (with presence one species bacteria) conditions. The B. suppressed by T. japonicus cultures. persist cultures, but its increased grown used RT bacteria strain as a food source, while were toxic rotundiformis. These suggest that can modify interspecific relationship between japonicus.
