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 (HR) 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 HR overlap with body mass explains many of these differences in allometric scaling of HR size. We conclude that, on a population scale, HR size and energetic requirement scale allometrically, but with different exponents.
异速生长比例关系有助于探索动物的空间利用模式，但种间研究无法揭示许多潜在机制。我们首次进行了种内研究，以掠食性鱼类白斑狗鱼（Esox lucius）为模型，探讨了跨越几个体重数量级的家域（HR）异速生长与能量需求之间的关系。与种间研究类似，我们发现空间利用随体重增加的速度（指数 = 1.08）比代谢比例理论预测的要快。我们的结果支持了一种理论，即家域重叠随体重增加可以解释家域大小异速生长的许多差异。我们得出结论，在种群尺度上，家域大小和能量需求呈异速生长，但指数不同。
