The project intends to extend predator–prey theory by developing a predation–risk model that incorporates individual differences in predation rate. Predation by introduced predators is the most significant cause of fauna decline in Australia and New Zealand. Current predator–prey theory is based on population-level processes and predator control used to protect threatened wildlife assumes that the removal of each predator is equally important. However, evidence suggests that in many cases only a few individual predators are responsible for population decline. If the physical or behavioural characteristics of successful individual predators can be identified then predator profiling can be used to control problem animals and improve the efficacy of feral animal control programs.

该项目旨在通过开发一个捕食风险模型来扩展捕食者-被捕食者理论，该模型将捕食率的个体差异纳入其中。引入的掠食者的捕食是澳大利亚和新西兰动物群减少的最重要原因。目前的捕食者-被捕食者理论是基于种群水平的过程，用于保护受威胁野生动物的捕食者控制假设每个捕食者的消除是同等重要的。然而，有证据表明，在许多情况下，只有少数个别捕食者是负责人口下降。如果可以识别成功的个体捕食者的身体或行为特征，那么捕食者分析可以用于控制问题动物并提高野生动物控制计划的效力。
