FIGURE 4.
Effects of a stomach and durophagous diet on (a) intestinal length, (b) diameter, and (c) surface area for 142 species of coral reef fishes. Estimates are posterior medians (circles), 50% credible intervals (CIs; thick lines) and 95% CIs (thin lines) from Bayesian phylogenetic hierarchical linear models after controlling for the remaining fixed and random effects. Posterior densities are also displayed (shaded regions)
