Association between the hand-wing index and mitochondrial dN molecular rates across species of the avian family Furnariidae. The relationship changes with body mass, showing a positive association between molecular rates and hand-wing index in small-bodied species, whereas the association appears negative in large-bodied species. Colours represent mid-quartile values of body mass, where darker colours indicate species with greater body mass. The predicted regression lines are also coloured for each of the mid-quartile values of body mass. Molecular rates are shown normalized and under a Box-Cox transformation
