  abstract = {{K}nowledge of the pathways of colonization is critical for risk assessment and management of weeds. {I}n this study we adopted a landscape genetics approach to assess the impact of human disturbances and large-scale environmental features on the colonization of a global agricultural weed, {R}aphanus raphanistrum. {W}e used nuclear microsatellite and chloroplast {DNA} sequence data to quantify the pattern of genetic diversity in 336 plants collected from 13 sites throughout the {C}ape {F}loristic {R}egion, {S}outh {A}frica, one of the world's recognized global biodiversity hotspots. {T}he lack of strong spatial genetic structure suggests that {R}. raphanistrum colonized throughout the {C}ape {F}loristic {R}egion via both local diffusive spread and long-distance jump dispersal. {F}urthermore, 47 % of analyzed plants contained {R}aphanus sativus (cultivated radish) chloroplast genomes, indicating historical and/or contemporary gene flow between wild and cultivated radish populations. {T}he prevalence of high genetic diversity and long-distance gene flow are discussed in the context of ecological risk assessment.},
