Individual variability in space use near power lines by a long-lived territorial raptor

Evaluating species responses to anthropogenic infrastructures and other habitat changes is often used to assess environmental impacts and to guide conservation actions. However, such studies are generally carried out at the population-level, disregarding inter-individual variability. Here, we investigate population- and individual-level responses towards power lines of a territorial raptor, the Bonelli’s eagle Aquila fasciata. We used GPS-PTT tracking data of seventeen adult eagles to model space use as a function of distance to transmission and distribution lines, while accounting for other habitat features known to affect this species. At population level, eagles increased the intensity of space use in the proximity of power lines (up to 1000 m), suggesting an attraction effect. At individual level, some eagles shared the general population attraction pattern, while others showed reduced intensity of space use in the proximity of power lines. These differential responses were unrelate...评估物种对人为基础设施及其他生境变化的响应，常被用于评估环境影响并指导保护行动。然而，此类研究通常仅在种群层面开展，忽略了个体间的异质性。本研究以具有领地性的猛禽——博内利雕（Bonelli’s eagle，学名Aquila fasciata）为研究对象，探讨其对输电线路的种群及个体层面响应。我们利用17只成年博内利雕的GPS-PTT追踪数据，将空间利用模式建模为与输电、配电线路距离的函数，同时纳入已知会影响该物种的其他生境特征作为控制变量。在种群层面，博内利雕在输电线路周边（1000米范围内）的空间利用强度更高，表明存在吸引效应。在个体层面，部分博内利雕契合种群整体的吸引模式，而另一些个体则在输电线路周边表现出更低的空间利用强度。此类差异化响应与……
