Table 2.
Measures of genetic differentiation calculated between the historical and contemporary sample groups, and between “age” class subsets within the contemporary sample group
| Phi ST | DAF | |
|---|---|---|
| Historical and contemporary | 0.028a | 0.040 |
| Historical and adult | 0.027a | 0.037 |
| Historical and young | 0.037a | 0.046 |
| Adult and young | 0.010a | 0.019 |
“Adult” refers to the subset of individuals in the contemporary sample group with a curved carapace length >65 cm; “Young” refers to the subset of individuals in the contemporary sample with a curved carapace length >15 and <35 cm.
a
Denoting significance at p < 0.001 for the Phi ST, DAF, the proportion of loci with significantly different allele frequencies (adjusted p‐value 0.0059).
