Relationship between dN/dS and log-transformed body mass for different substitution categories. a All substitution categories together (total; black circles), b GC-conservative substitutions (gray diamonds), c S-to-W substitutions (blue triangles), and d W-to-S substitutions (red squares). Each dot corresponds to a terminal branch of the avian phylogeny. Regression lines for each substitution category are shown using the same color scheme. Pearson correlation coefficients and their statistical significance are provided in the right upper corner of each panel
