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. specialized allometry home range behaviour metabolic ecology ANGLETERRE 036 080 12 3 art. 20150673 [3 p.] 2016 1744-9561 https://www.documentation.ird.fr/hor/fdi:010066788 10.1098/rsbl.2015.0673 1744-9561 [F B010066788] https://www.documentation.ird.fr/hor/fdi:010066788 https://www.documentation.ird.fr/intranet/publi/2016/05/010066788.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2016-06-02 2017-08-23 fdi:010066788 fre
