Beyond Abundance: An experimental study of the effects of predators on prey behaviour and reproduction. Understanding the influence of top predators on community composition and population dynamics at lower trophic levels is a central problem in ecology, with important implications for ecological theory and conservation biology. Our study will be among the first to examine effects of presence and absence of top-level predators on the behaviour, reproduction, and microhabitat use of mid-level predators. Understanding how the behaviour and ecology of lower-level species change in response to changes in abundance of top-level predators will increase the ability of managers to mitigate the impacts of changes in predator abundance on managed ecosystems.

《超越捕食：捕食者对猎物行为和繁殖影响的实验研究》。了解上层捕食者对低营养级群落组成和种群动态的影响是生态学的核心问题，对生态学理论和保护生物学具有重要意义。我们的研究将是第一个研究顶级捕食者的存在和不存在对中级捕食者的行为，繁殖和微栖息地使用的影响。了解低层物种的行为和生态如何随着顶层捕食者丰度的变化而变化，将提高管理人员减轻捕食者丰度变化对管理的生态系统的影响的能力。
