Chlorella vulgaris colonies were grown as nutrient agar for one week, followed by addition of Daphnia magna in overlying water for a second week. A range of concentrations of cadmium were added to the Chlorella or to the Chlorella followed by higher cadmium concentrations in the overlying fluid. A dose-dependent reduction in reproduction was observed with increased cadmium. When parent daphnids were first exposed to a lower cadmium concentration, and their offspring of preconditioned juvenile daphnids then exposed to a higher concentration, cadmium tolerance in new-born daphnids was observed.
将普通小球藻菌落作为营养琼脂培养一周，接着在覆盖水中添加大型溞再培养一周。向小球藻中添加一系列浓度的镉，或者先向小球藻添加镉，随后在覆盖液中添加更高浓度的镉。随着镉含量增加，观察到繁殖呈剂量依赖性减少。当亲代水蚤先暴露于较低镉浓度，然后将其预处理的幼体后代暴露于较高浓度时，观察到新生水蚤对镉的耐受性。
