Data from: Spatial variation in the relationship between performance and metabolic rate in wild juvenile Atlantic salmon
1. Maintenance metabolic rate (MR, the energy cost of self-maintenance) is linked to behavioural traits and fitness and varies substantially within populations. Despite having received much attention, the causes and consequences of this variation remain obscure. 2. Theoretically, such within-populat...
