Contribution of non-native plants to the phylogenetic homogenization of U.S. yard floras Abstract. Cultivation and spread of non-native plant species may result in either phylogenetic homoge- nization (increasing similarity) or differentiation (decreasing similarity) of urban floras. However, it is unknown how non-native species influence homogenization of cultivated versus spontaneously occurring species in cities, and which traits are associated with species that promote homogenization versus differentia- tion. In this study, we compared homogenization effects of cultivated and spontaneous non-native species in yard floras across and within seven widely distributed U.S. cities. Additionally, we explored which traits explained their particular contribution to …
