Table 2. AMOVA results of two grouping options.
| Grouping option | ΦST | ΦSC | ΦCT | % among groups | % among populations within groups | % within populations |
|---|---|---|---|---|---|---|
| Three clades | 0.90* | 0.61* | 0.73* | 73.62 | 16.13 | 10.25 |
| Divided by rivers (nine groups) | 0.85* | 0.57* | 0.66* | 65.61 | 19.55 | 14.85 |
Abbreviation: AMOVA, analysis of molecular variance. Φ refers to Phi statistic. ΦST refers to differentiation among groups, ΦSC refers to differentiation within populations, and ΦCT refers to differentiation within groups among populations.
