Table 1.
Estimation of diversity within native and introduced populations of Arctotheca populifolia and Petrorhagia nanteuilii including measures across three diversity orders: zero (allelic richness, R), unity (Shannon index, SH; and the effective numbers equivalent, 1Dwithin), and two (Hardy–Weinberg expected heterozygosity, HE; and the effective numbers equivalent, 2D). For both species, genetic differentiation within the native and introduced ranges was calculated using FST and Shannon's mutual information index (SHUA), and the numerical equivalent of SHUA (1Dbetween)
