Plot of standardized coefficients for canonical variables based upon discriminant function analysis of samples classified only by collection sites.
Little Cayman Island –open circles, San Salvador – closed squares, Lee Stocking Island – open squares.
Figure 2.
Plot of standardized coefficients for canonical variables based upon discriminant function analysis of samples classified only by collection depth.
Shallow (3–10 m) - circles, Medium depth (15–25 m) – open squares, Deep (30–50 m) – closed squares, and Very Deep (60–90) – diamonds

Figure 3.
Plot of marker frequencies for three markers identified in the FST outlier analysis to exhibit significant deviation from neutral expectations.
The three markers in the Lee Stocking Island samples all showed significantly higher FST compared to neutral expectations suggesting positive selection. The three markers in the Little Cayman Island data set all showed significantly lower FST suggesting balancing selection.
