Groups of "cooper-enriched" and "copper-deficient" isopods were allowed to choose between three batches of birch litter differing in their copper contents. The relative amounts of litter ingested by the three species were the following (ranges of average contribution of each type of litter to total amount ingested): Thus the selection of food in these animals appears to be influenced by the status of the copper reserves in their bodies.
将“富含铜”和“缺铜”的等足类动物分组，让它们在三批铜含量不同的桦树落叶中进行选择。这三个物种摄取的落叶相对量如下（每种落叶对总摄入量的平均贡献范围）：因此，这些动物对食物的选择似乎受其体内铜储备状况的影响。
