Does Intraspecific Size Variation in a Predator Affect Its Diet Diversity and Top-Down Control of Prey?
Figure 5
Post-hoc analysis of relationships between diet variation and the prey community in the enclosures.
Mean pairwise diet dissimilarity (E) is compared to a) benthic invertebrate density and b) benthic invertebrate composition, measured as the first RDA axis. Symbols correspond to spatial blocks; black symbols indicate high size variance treatment, while grey symbols indicate low size variance.
