Table 2.

Population genetic diversity indices for native, and non-native (introduced and invasive) populations of various Prosopis species, putative hybrids and Prosopis spp. individuals from South Africa. Native Prosopis and non-native Prosopis groups (i.e. all native and non-native Prosopis individuals, respectively) were analysed as well. Statistics were calculated as mean values of each index over the seven loci analysed. N = number of samples; H_E = expected heterozygosity expected; H_O = observed heterozygosity observed; F_IS = inbreeding coefficient.
