Carnivore predation on livestock is a complex management and policy challenge, yet it is also intrinsically an ecological interaction between predators and prey. Human-wildlife interactions occur in socioecological systems in which human and environmental processes are closely linked. However, underlying human-wildlife conflict and key to unpacking its complexity are concrete and identifiable ecological mechanisms that lead to predation events. To better understand how ecological theory accords with interactions between wild predators and domestic prey, we developed a framework to describe ecological drivers of predation on livestock. We based this framework on foundational ecological theory and current research on interactions between predators and domestic prey. We used this framework to examine ecological mechanisms (e.g., density-mediated effects, behaviorally mediated effects, and optimal foraging theory) through which specific management interventions operate, and we analyzed the ecological determinants of failure and success of management interventions in 3 case studies: snow leopards (Panthera uncia), wolves (Canis lupus), and cougars (Puma concolor). The varied, context-dependent successes and failures of the management interventions in these case studies demonstrated the utility of using an ecological framework to ground research and management of carnivore-livestock conflict. Mitigation of human-wildlife conflict appears to require an understanding of how fundamental ecological theories work within domestic predator-prey systems.
肉食性动物捕食家畜是一个复杂的管理和政策挑战,但它也是捕食者和猎物之间内在的生态相互作用。人类与野生动物的相互作用发生在社会生态系统中,人类和环境过程紧密相连。然而,导致捕食事件的根本的人类与野生动物冲突和关键在于可识别的生态机制。为了更好地理解生态理论如何与野生捕食者和家畜之间的相互作用一致,我们制定了一个描述捕食家畜的生态驱动因素的框架。我们基于基础生态理论和当前关于捕食者与家畜之间相互作用的研究,建立了这个框架。我们通过这个框架来研究生态机制(例如,密度介导的效应、行为介导的效应和最适觅食理论),这些机制通过具体的管理干预措施发挥作用,我们还分析了 3 个案例研究中管理干预措施失败和成功的生态决定因素:雪豹(Panthera uncia)、狼(Canis lupus)和美洲狮(Puma concolor)。这些案例研究中管理干预措施的不同、取决于背景的成功和失败,证明了使用生态框架来为研究和管理肉食性动物与家畜冲突提供基础的实用性。缓解人类与野生动物的冲突似乎需要理解基本生态理论如何在国内的捕食者-猎物系统中发挥作用。
