Analyses of directionality associated with ecological covariates. a-c: trophic level, d-f: dietary breadth, and g-i: relative home range size. Columns indicate analyses of skull length (a, d, g), skull width (b, e, h), and skull length-to-width (c, f, i). Forest plot lines that do not cross the dotted zero line are associated with a significant effect. Red arrows on the skull illustrations indicate the morphology associated with the positive and negative effect sizes on each plot
