Relative support is indicated by small sample AICcWs. The evolutionary rate is given by $σ^{2}$ , whereas scalar refers to model-specific parameters [accelerating/decelerating rate (ACDC) = r; diversity dependent models = ψ, trended random walk (Trend) = μ, OU = α]. For variable rate (BMV) and multipeak OU models, diet-specific values are provided in the final three columns. AICc, corrected Akaike information criterion; lnLk, ln(likelihood).
