Figure 4 
Trophic diversity (exp (H')) as a function of the number of stomachs analyzed for Summer Flounder (Paralichthys dentatus), 
Weakfish ( Cynoscion regalis), Bluefish ( Pomatomus saltatrix), and Striped Bass ( Morone saxatilis), collected from June (top 
row) to October (bottom row) in 2005 off the coast of New Jersey. Plotted are the means of 100 randomizations for a selected 
number of stomachs (error bars indicate ±1 standard deviation). Lines with triangles, circles, or squares indicate results for 
small, medium, or large size classes, respectively. Note that the x-axis scales are different across species.
