Fig. 6: Principal components analysis and dot plots showing differences in the optimal or mean trait values for each diet.
From: Complexity and weak integration promote the diversity of reef fish oral jaws
A Principal component analysis of optimal or mean trait values for all 13 oral jaw traits showing that, while trait combinations associated with diet are largely aligned with an overarching trade-off between jaw strength and mobility, there is variation in trait combinations beyond this trend. The black polygon represents diets that feed primarily through biting. The gray polygon represents diets that feed primarily through suction. Omnivores (pink circle) are represented by an almost equal split of biters and suction feeders. B Dotplot showing the variation in trait values between the diet groups for each trait. Asterisks denote traits in which the mean trait value was used instead of the optimal trait value as the multi-peak OU models could not converge.
