Animals experience varying levels of predation risk as they navigate heterogeneous landscapes, and behavioral responses to perceived risk can structure ecosystems. The concept of the landscape of fear has recently become central to describing this spatial variation in risk, perception, and response. We present a framework linking the landscape of fear, defined as spatial variation in prey perception of risk, to the underlying physical landscape and predation risk, and to resulting patterns of prey distribution and antipredator behavior. By disambiguating the mechanisms through which prey perceive risk and incorporate fear into decision making, we can better quantify the nonlinear relationship between risk and response and evaluate the relative importance of the landscape of fear across taxa and ecosystems.
动物在穿越异质景观时会经历不同程度的捕食风险,而对感知到的风险的行为反应可以构造生态系统。恐惧景观的概念最近成为描述风险、感知和反应的空间变化的核心。我们提出了一个框架,将恐惧景观(定义为猎物对风险感知的空间变化)与潜在的物理景观和捕食风险联系起来,并与猎物分布和捕食防御行为的模式联系起来。通过澄清猎物感知风险的机制,并将恐惧纳入决策过程,我们可以更好地量化风险与反应之间的非线性关系,并评估恐惧景观在不同分类群和生态系统中的相对重要性。
