Genetic diversity and differentiation in south-western Australian bloodwoods (

An understanding of how variation is shared within and among closely related species important for evolutionary processes managing biological diversity. We studied genetic structure in the three occurring south-western Australia that form small distinct monophyletic section Calophyllae genus Corymbia. compared diversity nuclear microsatellites chloroplast DNA sequences two with patchy distributions, namely, Corymbia haematoxylon (Maiden) K.D. Hill & L.A.S. Johnson ficifolia (F. Muell.) Johnson, widespread congener, C. calophylla (Lindl.) Johnson. Consistent predictions influence range abundance on Australian flora, population differentiation was higher restricted than widespread, semicontinuous calophylla. Genetic similar to calophylla, but lower highly localised ficifolia, likely owing bottlenecks. All were distinguished by SSR variation, each haplotypes from incomplete lineage sorting ancestral introgression. Limited evidence recent hybridisation populations also present.
