Data from: Allometric scaling of intraspecific space use

Allometric scaling relationships enable exploration of animal space use patterns, yet interspecific studies cannot address many of the underlying mechanisms. We present the first intraspecific study of home range allometry relative to energetic requirements over several orders of magnitude of body mass, using as a model the predatory fish, pike Esox lucius. Analogous with interspecific studies, we show that space use increases more rapidly with mass (exponent = 1.08) than metabolic scaling theories predict. Our results support a theory that suggests increasing home range overlap with body mass explains many of these differences in allometric scaling of home range size. We conclude that, on a population scale, home range size and energetic requirement scale allometrically, but with different exponents.异速缩放（allometric scaling）关系可用于探究动物空间利用模式，然而种间（interspecific）研究无法阐明诸多潜在作用机制。本研究以肉食性鱼类白斑狗鱼（Esox lucius）为模式物种，首次针对体重跨越多个数量级的种群开展了家域异速生长（home range allometry）与能量需求相关性的种内（intraspecific）研究。与种间研究类似，本研究发现空间利用随体重增长的速率（缩放指数为1.08）远超代谢缩放（metabolic scaling）理论的预测结果。本研究结果支持某一理论假说：该假说提出家域重叠度随体重提升可解释家域大小异速缩放的诸多差异。本研究最终得出结论：在种群尺度下，家域大小与能量需求均呈异速缩放关系，但二者具有不同的缩放指数。
