Measures of genetic structure and gene flow among selected population groupings (as identified by STUCTURE at K = 3). F_ST and estimated number of migrants (m) derived from N_e = 100 and derived from ^SH_UA are presented, as well as relevant percentage of genetic diversity partitioned to within, between and among population groups (AMOVA) and significance values.
