在保护生物学中，研究人员经常想研究濒危种群生存状况不佳的原因，但由于后勤或政治原因无法直接研究。相反，他们研究了一个物种，以取代一个关注，希望它将投光对保护问题。在这里，我们概述了这种方法的基本假设。替代品可以是不同的种群或物种，并且可以因为它们在生物学上与目标相似或代表目标所属的一系列物种而被选择。它们也可用于开发与保护目标相关的预测模型。为使替代品适当，它们应具有相同的关键生态或行为特征，使目标对环境干扰敏感，人口生命率和干扰程度之间的关系应与目标相匹配。这些条件不太可能适用于大多数情况下，使用替代物种来预测濒危种群对干扰的反应是值得怀疑的。
In conservation biology, researchers often want to study the reasons why an endangered population is faring poorly but are unable to study it directly for logistical or political reasons. Instead they study a species that substitutes for the one of concern in the hope that it will cast light on the conservation problem. Here we outline the assumptions underlying this approach. Substitutes can be different populations or species and may be chosen because they are similar biologically to the target or representatives of a constellation of species of which the target is one. They also may be used to develop a predictive model to which the conservation target can be related. For substitutes to be appropriate, they should share the same key ecological or behavioral traits that make the target sensitive to environmental disturbance and the relationship between population vital rates and level of disturbance should match that of the target. These conditions are unlikely to pertain in most circumstances and the use of substitute species to predict endangered populations' responses to disturbance is questionable.
