Figure 4From: Effects of predation pressure and resource use on morphological divergence in omnivorous prey fishContribution of benthic prey to diet of roach. Comparison of benthic contribution in diets of roach, revealed by gut content analysis (open symbols; depicted are mean values ± 95% confidence interval) and stable isotope analysis (shaded symbols; depicted are mean values ± 95% bayesian credibility interval) for roach from Gollinsee and Schulzensee.Back to article page
