In an energy-limited environment, caloric investments in one characteristic should trade-off with investments in other characteristics. In high pathogen ecologies, biasing energy allocation towards immune function over growth would be predicted, given strong selective pressures against early-life mortality.

高病原体人群中青春期前儿童身高和免疫功能权衡的证据

在能量有限的环境中，对一个特征的热量投资应该与对其他特征的投资进行权衡。在高病原体生态系统中，考虑到对生命早期死亡率的强大选择压力，可以预测能量分配会偏向免疫功能而不是生长。
