The pace-of-life syndrome describes covariation between life-history, behavioral and physiological traits; while, the emerging behavioral-bioenergetics theory proposes mechanistic links between those traits in a spatial-ecological context. However, little is known about the association between the limits to metabolic rate and spatial performance (i.e., mobility, home range size) in free-living individuals. Here we show, for the first time at the intra-specific level, that mobility traits increased with the aerobic exercise capacity (<(V)over dot>O(2)max) in a wild rodent, the bank vole (Myodes glareolus): <(V)over dot>O(2)max affected directly the movement intensity, which in turn affected home ranges. The results show that evolution of high <(V)over dot>O(2)max could be driven by selection for spatial performance traits, and corroborate one of the key assumptions of the behavioral-bioenergetics theory. However, the minimum maintenance metabolism, measured as the basal metabolic rate (BMR), was not correlated with movement intensity, and the direction of the BMR-home range correlation tended to change with age of the voles. The latter result indicates that testing the theory will be particularly challenging.
