Means and s.e. values for population divergence (FST values) between coastal populations (C/C), coastal and island populations (C/I), and island populations (I/I). The three groups of FST estimates were significantly different by a Tukey–Kramer HSD test (significant differences indicated by letters [a], [b] and [c]), with C/C populations showing the lowest divergence and I/I populations showing the highest.
