Results of the hierarchical analysis of molecular variance that partitioned genetic variation between atoll systems (FRT), among sites relative to variation within both atoll systems (FSR), and among sites relative to overall variation (FST). Additionally, we calculated the variation partitioned among the sites relative to variation within each atoll system (FSR Rowleys and FSR Scott). A standardized measure of all the F -statistics (F′RT, F′SR, and F′ST) was also calculated according to the method of Meirmans (2006). Exact tests were applied to asses statistical significance at each hierarchical level; * P < 0.001 and appears next to F′ estimates.
| Adults | Rowleys | Scott | All |
|---|---|---|---|
| FRT: between systems | – | – | 0.002 |
| FSR: within systems | – | – | 0.000 |
| FST: among sites | 0.000 | 0.000 | 0.002 |
| F′RT: between systems | – | – | 0.011* |
| FSR: within systems | – | – | 0.000 |
| F′ST: among all sites | 0.000 | 0.002* | 0.011* |
