| Region (n) | Mean allelic richnessa | Fis b | Outcrossing ratec | Region-specific genotypes (%)d |
|---|---|---|---|---|
| West Auckland (82) | 7±1.5 | 0.73±0.19 | 0.12–0.16–0.20 | 100 |
| Waiheke Island (96) | 7.6±2.6 | 0.61±0.20 | 0.08–0.11–0.14 | 90 |

Abbreviations: n, the number of genotypes; NZ, New Zealand.
a
Mean allelic richness was calculated for each locus independently by rarefaction using HP-rare and the mean and s.d. across all loci are reported.
b
The mean inbreeding coefficients across all ten loci (±s.d.); a value of 1 indicates a completely inbred population.
c
Average proportion of the mating of spores from independent tetrads per meiotic generation surrounded by 2 log likelihood support limits, which are equivalent to the 95% confidence intervals, calculated following Johnson et al. (2004).
d
Percentage of genotypes found in that region only.
