Figure D3. Visualization of the R2 values from linear models investigating the relationship between the covariances of dentigerous arm width, lower jaw length, maxilla length, and palatine height and the traits labeled in each graph for Caribbean, SSI generalist-only, and SSI radiating groups. The first column of graphs shows a relationship between traits that shift across groups in a manner that suggests that they promote diversification. The second column shows relationships between traits which may inhibit diversification specifically in SSI generalist-only groups, as they deviate from those seen in the Caribbean and SSI radiation.
