Isolation-by-distance in Acanthochromis polyacanthus on the Great Barrier Reef. Relationship between genetic differentiation and linear geographical distance. ΦST = 0.00051 (0.00043 - 0.00058) km + 0.41 (0.36 - 0.47).

Figure 3
Pairwise genetic distances and asymmetric migration rates among reefs within regions. The thickness of arrows indicates the strength of genetic structure (ΦST: a – c) or rate of migration (4Nem:
d – f) and the colour indicates statistical difference. For pairwise
genetic distances black arrows indicate estimates significantly
different from 0. For migration rates black arrows indicate that
reciprocal estimates were different (95% confidence intervals of did
not overlap) and grey arrows indicate that reciprocal estimates were
not different (95% confidence intervals of estimates overlapped).

Figure 4
Mismatch distributions of pairwise sequence differences in Acanthochromis polyacanthus among regions and reefs.
Panels represent the mismatch frequency distribution of individual
reefs (n = 15) or regions (n = 3). Location abbreviations follow Table
1.
