Species core isotopic niches and Bayesian credibles by region, based on standard ellipse areas.

(A) Standard ellipse areas contain 40% of the data for gray triggerfish (gray), and red snapper (red). Stable isotope means and ellipses (SEAc) from length adjusted stable isotope values are shown for the east (circles, solid ellipses), central (squares, dotted ellipses), and west (triangles, dashed ellipses) regions; error bars represent the standard error. (B) Bayesian credible intervals for gray triggerfish and red snapper standard ellipse areas by region. Black points represent the mean, while gray boxes represent 50, 75, and 95% credible intervals. Red x’s represent SEA corrected for sample size (SEAc).
