Notations are as follows: N, sample size; H O, observed heterozygosity; H E, expected heterozygosity; A R, allelic richness; R, Queller and Goodnight's relatedness index; N e(LD), effective population size based on linkage disequilibrium; N e(ABC), effective population size based on approximate Bayesian computation; M c, Garza & Williamson's M‐ratio and its critical value; (P < 0.05*; P < 0.01**; P < 0.001***), significance for H E excess tests based on a Wilcoxon signed‐rank test; A priv, number of private alleles; and A mono, number of monomorphic alleles.
Sites with multiple sampling locations are the West Santa Ynez Mountains (Salsipuedes Cr., Cañada Honda and Jalama Cr.) and the Central Santa Ynez Mountains (Arroyo Quemado and Arroyo Hondo). We do not report N e estimates or results of bottleneck tests at sites with fewer than 10 samples.
