From: The relationship between sternum variation and mode of locomotion in birds
Overall sternal shape, represented by the Regression Score, plotted against log-transformed body mass, with each point representing an individual specimen. The solid line indicates the regression line from the best procD.pgls model sternal shape ~ body mass + sternum size + forelimb-driven lift-based propulsion + aerial flight + terrestriality + cursoriality + burst flight + foot-propelled swimming and diving + continuous flapping + soaring (slope = 0.00354, S.E. = 0.000578, p = 1.67 × 10−8, R2 = 0.267). Datapoint colors and symbols are indicated by simplified locomotory categories provide in the legend
