Fig. 4. Feeding strategy diagram for individuals of three size classes (A: <400 mm TL; B: 400-500 mm TL; C:>500 mm TL) of the dusky grouper Mycteroperca marginata. Prey-specific abundance plotted against frequency of occurrence of food items in the diet of the dusky grouper. The inserted boxed (A) represents a conceptual diagram of a resource niche width characterized by a high between-phenotype component (sensu Amundsen et al., 1996) to niche width contribution. The number of individuals analyzed in each size class is 29, 34 and 15, respectively.
