Linear regression on species values compared with independent contrasts (ICs). Solid lines represent regressions through the pooled dataset. Dashed lines represent partitioned (wet/dry) data.

(c) Log–log plot of spatular width (μm) versus body mass (g) for 67 taxa. (d) Phylogenetically corrected values for spatular width versus body mass.
