Figure 3. The Multivariate trait values of SSI radiating pupfish are on average larger than the multivariate trait values of SSI generalist-only and Caribbean pupfish groups. Violin plots display the posterior draws from a Bayesian mixed effects model with the 18 craniofacial trait values as the response variable, pupfish group and species designations as fixed effects and population ID as a random effect. Black points and lines represent the median and 95% HDI for each group. Dots show average trait values for individuals.
