Analysis of covariance table.

Fish mass (M), total length (LT), collection site (Collected), rearing treatment (Treatment), absolute maximum metabolic rate (MMR, mg O2 h-1), aerobic scope (AS, mg O2 h-1), pectoral fin aspect ratio (AR). R2LMM(m) is the marginal R2 representing the variance explained by fixed factors in the model, and R2LMM(c) is the conditional R2 representing the variance explained by fixed and random factors in the model. Factors in bold represent statistically significant effects (α = 0.05). Analysis of covariance table.
