Abstract

Resting metabolic rates can vary greatly between individuals of the same species. These differences are generally repeatable and show moderate-to-high heritability, suggesting that they could be a target for natural selection. The present study therefore aimed to determine if inter-individual differences in resting metabolic rates (RMR) in garden skinks Lampropholis delicata were associated with inter-individual differences in a suite of physiological and behavioural variables: aerobic capacity, burst sprinting speed and thermal preference. Whole-animal measures of aerobic capacity and RMR were significantly positively correlated, but mass-independent measures were not. Burst sprinting speed and thermal preference were also not correlated with RMR.
